HECHT, Justice, delivered the opinion of the Court in which PHILLIPS, Chief Justice, and ENOCH, SPECTOR, BAKER and ABBOTT, Justices, join. R. intervened in her parents’ divorce proceeding, alleging that her father, S., was negligent by sexually abusing her until she was seventeen years old. (Given the sensitive nature of these allegations, we refer to the parties only by initials to avoid the use of proper names.) Because R. did not sue her father within two years of her eighteenth birthday as required by the applicable statutes of limitations, her action is barred as a matter of law unless the discovery rule permits her to sue within two years of when she knew or reasonably should have known of the alleged abuse. R. contends that the discovery rule should apply in this case because she repressed all memory of her father’s abuse until about a month after she turned twenty, some three months before she intervened in the divorce action. The district court directed a verdict against R. on the grounds that the discovery rule does not apply in this case, and that R. adduced no evidence of abuse. A divided court of appeals reversed and remanded for a new trial. 880 S.W.2d 804. We reverse the judgment of the court of appeals and affirm the judgment of the district court on limitations grounds. I Before we review the evidence in this case it is important to have clearly in mind the issue that is crucial in determining whether to apply the discovery rule. To pose that issue we begin with an analysis of our discovery rule jurisprudence. We have long recognized the salutary purpose of statutes of limitations. In Gautier v. Franklin, 1 Tex. 732, 739 (1847), we wrote that statutes of limitations are justly held “as statutes of repose to quiet titles, to suppress frauds, and to supply the deficiencies of proof arising from the ambiguity, obscurity and antiquity of transactions. They proceed upon the presumption that claims are extinguished, or ought to be held extinguished whenever they are not litigated in the proper forum at the prescribed period. They take away all solid ground of complaint, because they rest on the negligence or laches of the party himself; they quicken diligence by making it in some measure equivalent to right....” [Joseph P. Story, Conflicts of Law 482.] More recently, we explained: Limitations statutes afford plaintiffs what the legislature deems a reasonable time to present their claims and protect defendants and the courts from having to deal with cases in which the search for truth may be seriously impaired by the loss of evidence, whether by death or disappearance of witnesses, fading memories, disappearance of documents or otherwise. The purpose of a statute of limitations is to establish a point of repose and to terminate stale claims. Murray v. San Jacinto Agency, Inc., 800 S.W.2d 826, 828 (Tex.1990). The enactment of statutes of limitations is, of course, the prerogative of the Legislature. At the time this case was filed and tried, the applicable statute was the one governing personal injury actions generally, which provided: “A person must bring suit for ... personal injury ... not later than two years after the day the cause of action accrues.” Act of May 17, 1985, 69th Leg., R.S., ch. 959, § 1, 1985 Tex.Gen.Laws 3242, 3252, formerly codified as Tex.Civ.PraC. & Rem. Code § 16.003(a). The code contains two other provisions relevant to this ease. One is: “If a person entitled to bring a personal action is under a legal disability when the cause of action accrues, the time of the disability is not included in the limitations period.” Tex.Civ.Prac. & Rem.Code § 16.001(b). The other is: “For the purposes of this sub-chapter, a person is under a legal disability if the person is: (1) younger than 18 years of age_” Id. § 16.001(a). Thus, a person has until his or her twentieth birthday (or the next business day, id. § 16.072) to bring suit for personal injury from sexual assault if — and here we come to the root of the problem in the case before us — the cause of action “accrued” while the person was a minor. In 1995, the Legislature enacted a special five-year statute of limitations for sexual abuse cases: “A person must bring suit for personal injury not later than five years after the day the cause of action accrues if the injury arises as a result of conduct that violates: (1) Section 22.011, Penal Code (sexual assault); or (2) Section 22.021, Penal Code (aggravated sexual assault.” Tex.Civ.Prac. & Rem.Code § 16.0045(a); Act of May 27, 1995, 74th Leg., R.S., ch. 739, 1995 Tex.Gen.Laws 3850. This new statute was not enacted until long after the present case was filed and tried and therefore does not govern. Raley v. Wichita County, 123 Tex. 494, 72 S.W.2d 577, 579 (1934). We mention it here to point out that under both the new statute and its predecessor, the prescribed period begins to run on the day the cause of action “accrues”. Many other statutes peg the beginning of the limitations period on the date the cause of action “accrues”. Occasionally the date of accrual is defined. E.g., Tex.Civ.Prac. & Rem.Code § 16.003(b) (a wrongful death cause of action “accrues on the death of the injured person”). More often, however, the definition of accrual is not prescribed by statute and thus has been left to the courts. As a rule, we have held that a cause of action accrues when a wrongful act causes some legal injury, even if the fact of injury is not discovered until later, and even if all resulting damages have not yet occurred. Trinity River Auth. v. URS Consultants, Inc., 889 S.W.2d 259, 262 (Tex.1994); Quinn v. Press, 135 Tex. 60, 140 S.W.2d 438, 440 (1940). We have not applied this rule without exception, however, and have sometimes held that an action does not accrue until the plaintiff knew or in the exercise of reasonable diligence should have known of the wrongful act and resulting injury. Trinity River Auth., 889 S.W.2d at 262. (Deferring accrual and thus delaying the commencement of the limitations period is distinct from suspending or tolling the running of limitations once the period has begun.) We first referred to this exception as the “discovery rule” in Gaddis v. Smith, 417 S.W.2d 577, 578 (Tex.1967). We have sometimes used the phrase to refer generally to all instances in which accrual is deferred, including fraud and fraudulent concealment. Williams v. Khalaf, 802 S.W.2d 651, 657 (Tex.1990) (citing a case that “involved the ‘discovery rule’ since there was a claim of fraudulent concealment”); Moreno v. Sterling Drug, Inc., 787 S.W.2d 348, 351 (Tex.1990) (citing fraud case as one in whieh discovery rule applied). See also Robinson v. Weaver, 550 S.W.2d 18, 24 n. 2 (Tex.1977) (Pope, J., dissenting) (“The ‘discovery rule’ applies in actions based on fraud ... and fraudulent concealment in medical malpractice cases_”). At other times we have distinguished between fraudulent concealment and the discovery rule. Willis v. Maverick, 760 S.W.2d 642, 647 (Tex.1988) (besides asserting the discovery rule, plaintiff also alleged that fraudulent concealment tolled limitations); Weaver v. Witt, 561 S.W.2d 792, 793-794 (Tex.1977) (per curiam) (noting that if defendant moves for summary judgment on limitations, the burden of proving fraudulent concealment to avoid summary judgment is on the plaintiff, but the burden of proving the date plaintiff knew or should have known of injury to obtain summary judgment is on defendant); Nichols v. Smith, 507 S.W.2d 518, 521 (Tex.1974) (noting that plaintiff asserted fraudulent concealment only and not the discovery rule). See also Murray, 800 S.W.2d at 831 (Spears, J., dissenting) (“Fraudulent concealment gives rise to another such practical exception [besides the discovery rule] to the injury based rule of accrual.”); Moreno, 787 S.W.2d at 367 n. 6 (Doggett, J., dissenting) (referring to “common-law tolling principles such as the doctrine of fraudulent concealment and the discovery rule.”) Strictly speaking, the cases in which we have deferred accrual of causes of action for limitations purposes fall into two categories: those involving fraud and fraudulent concealment, and all others. The deferral of accrual in the latter cases is properly referred to as the discovery rule. We observe the distinction between the two categories because each is characterized by different substantive and procedural rules. Weaver, 561 S.W.2d at 793-794. See American Petrofina, Inc. v. Allen, 887 S.W.2d 829 (Tex.1994); Woods v. William M. Mercer, Inc., 769 S.W.2d 515, 518 (Tex.1988). We have considered the applicability of the deferred accrual exception to the legal injury rule in an assortment of settings. See Willis, 760 S.W.2d at 646 (attorney malpractice in drafting divorce decree led to forced partition of home; held discovery rule applies when lawyer’s expertise and client’s ignorance of the law make wrong undiseovera-ble); Nelson v. Krusen, 678 S.W.2d 918, 923 (Tex.1984) (child bom with muscular dystrophy after doctor informed parents that mother did not carry muscular dystrophy gene; held statute precluding discovery rule was unconstitutional); Weaver, 561 S.W.2d at 794 (negligently performed hemorrhoidectomy damaged plaintiffs rectal nerves and muscles, causing loss of bowel control; held doctor’s affidavit of last examination date was insufficient to negate discovery rule); Robinson, 550 S.W.2d at 22 (misdiagnosis when one disc repaired and another later removed; held discovery rule did not apply when fact of injury was unclear and no physical evidence established negligence); Kelley v. Rinkle, 532 S.W.2d 947, 949 (Tex.1976) (false and libelous credit report unsuspected until plaintiff refused credit; held discovery rule applies despite strong counterargument based on “intangible nature of the evidence and of the injury”); Nichols, 507 S.W.2d at 519-520 (nerves severed during operation and plaintiff assured that nerves would heal, and plaintiffs digestive disorders attributable to mistake; held accrual not delayed because fraudulent concealment not shown and discovery rule not alleged); Hays v. Hall, 488 S.W.2d 412, 414 (Tex.1972) (negligence in performing vasectomy confirmed by subsequent pregnancy; held discovery rule applies); Gaddis, 417 S.W.2d at 580 (foreign object left in patient’s body during surgery; held discovery rule applies); International Bankers Life Ins. Co. v. Holloway, 368 S.W.2d 567, 580 (Tex.1963) (corporate officers and directors engaged in self-dealing, received commissions on stock sales, and sold personal shares of corporate stock in competition with corporation’s own offerings; held accrual was delayed for property sale and commissions, and fact issue existed as to whether personal stock sales were discoverable by board); Slay v. Burnett Trust, 143 Tex. 621, 187 S.W.2d 377, 394 (1945) (secret dealings by trustee who conceded application of discovery rule; held facts did not alert beneficiary to delve into transactions); Ruebeck v. Hunt, 142 Tex. 167, 176 S.W.2d 738, 740 (1943) (use of inferior, noncomplying felt under roof shingles, spaced too far apart, discovered only when roof completely torn up; held fraud delayed accrual because roof and felt were invisible from ground and because homeowner trusted general contractor to inspect); Quinn, 140 S.W.2d at 441 (loan contract fraud discovered, but suit not brought until remedies under contract exhausted; held fraud action accrues from time of discovery, not when damages ascertained with certainty); Port Arthur Rice Milling Co. v. Beaumont Rice Mills, 105 Tex. 514, 143 S.W. 926, 929 (1912) (fraud in chattel mortgage admitted; held discovery rule applies when plaintiff did not and could not have discovered defendant’s representations were false); Houston Water-Works Co. v. Kennedy, 70 Tex. 233, 8 S.W. 36, 38 (1888) (property damage to building; held discovery rule did not apply); Rowe v. Horton, 65 Tex. 89, 92 (1885) (mutual mistake in land conveyance; held even if discovery rule applied, plaintiff did not show due diligence); Kuhlman v. Baker, 50 Tex. 630, 637 (1879) (land fraud in giving an illiterate a quitclaim deed representing it as warranty deed; held while fraud tolls limitations, plaintiff failed to exercise due diligence in discovering fraud); Fibreboard Corp. v. Pool, 813 S.W.2d 658, 679 (Tex.App.-Texarkana 1991), writ granted, 35 Tex.Sup.Ct.J. 674 (Apr. 29, 1992), writ denied as improvidently granted, 36 Tex.Sup.Ct.J. 162 (Nov. 11, 1992), cert. denied, 508 U.S. 909, 113 S.Ct. 2339, 124 L.Ed.2d 250, 509 U.S. 923, 113 S.Ct. 3037, 125 L.Ed.2d 724, 509 U.S. 933, 113 S.Ct. 3064, 125 L.Ed.2d 746 (1993) (report stated plaintiff’s chest x-ray consistent with asbestosis, but plaintiff was not informed of the report; held discovery rule applied); Turner v. PV Int’l Corp., 765 S.W.2d 455, 468 (Tex.App.-Dallas 1988), writ denied per curiam, 778 S.W.2d 865 (Tex.1989) (extramarital affair admitted in alienation of affections suit; held discovery rule applied). The justifications we have offered for deferring accrual have been diverse, somewhat inconsistent, and often overly broad. Fraud, we have said, in and of itself prevents running of the statute of limitations, e.g., Ruebeck, 176 S.W.2d at 739; Port Arthur Rice Milling, 143 S.W. at 929, as does fraudulent concealment, e.g., Nichols v. Smith, 507 S.W.2d 518, 519-520 (Tex.1974); Estate of Stonecipher v. Estate of Butts, 591 S.W.2d 806, 809 (Tex.1979); Borderlon v. Peck, 661 S.W.2d 907, 908-909 (Tex.1983). We have applied the discovery rule because of a special relationship between the plaintiff and defendant. E.g., Willis, 760 S.W.2d at 645-646 (attorney and client); Slay, 187 S.W.2d at 388-393 (trustee and beneficiary). Even apart from such a relationship, we have indicated that the discovery rule applies when it is otherwise difficult for the injured party to learn of the wrongful act. Gaddis, 417 S.W.2d at 580 (leaving surgical sponge in plaintiffs body). We have characterized barring claims before plaintiffs knew they had them “shocking results”. Id. at 581. On the other hand, we have observed: Statutes of limitations are not directed to the merits of any individual case, they are a result of legislative assessment of the merits of cases in general. The fact that a meritorious claim might thereby be rendered nonassertible is an unfortunate, occasional by-product of the operation of limitations. All statutes of limitations provide some time period during which the cause of action is assertible. However, preclusion of a legal remedy alone is not enough to justify a judicial exception to the statute. The primary purpose of limitations, to prevent litigation of stale or fraudulent claims, must be kept in mind. Robinson, 550 S.W.2d at 20. A principal factor in deciding whether to apply the discovery rule has been to what extent the claim was objectively verifiable. E.g., Gaddis, 417 S.W.2d at 581 (leaving a surgical sponge in a body “is a peculiar type of case which is not particularly susceptible to fraudulent prosecution”); Robinson, 550 S.W.2d at 21 (“Unlike Gaddis v. Smith there exists in the present case [alleging misdiagnosis of herniated intervertebral disc] no physical evidence which in-and-of-itself establishes the negligence of some person.”); Kelly, 532 S.W.2d at 949 (credit defamation clear from written report). While the language in the opinions in these cases varies, a general principle unites them. Computer Associates International, Inc. v. Altai Inc., 918 S.W.2d 453 (Tex.1996). Accrual of a cause of action is deferred in two types of cases. In one type, those involving allegations of fraud or fraudulent concealment, accrual is deferred because a person cannot be permitted to avoid liability for his actions by deceitfully concealing wrongdoing until limitations has run. The other type, in which the discovery rule applies, comprises those cases in which “the nature of the injury incurred is inherently undiscoverable and the evidence of injury is objectively verifiable.” Id. at 456. These two elements of inherent undiscoverability and objective verifiability balance the conflicting policies in statutes of limitations: the benefits of precluding stale or spurious claims versus the risks of precluding meritorious claims that happen to fall outside an arbitrarily set period. Restated, the general principle is this: accrual of a cause of action is deferred in cases of fraud or in which the wrongdoing is fraudulently concealed, and in discovery rule cases in which the alleged wrongful act and resulting injury were inherently undiscoverable at the time they occurred but may be objectively verified. This principle, while not expressed in every deferred accrual case, is derived from them and best defines when the exception to the legal injury rule has been and should be applied. We have considered the “inherently undis-coverable” element of the discovery rule in several cases. Willis, 760 S.W.2d at 645 (lawyer’s error could not be discovered by client who was ignorant of the law); Nelson, 678 S.W.2d at 923 (malpractice in muscular dystrophy gene screening could not be discovered by parents until child showed symptoms); Kelley, 532 S.W.2d at 949 (false credit report could not be discovered until credit denied); Hays, 488 S.W.2d at 414 (“One who undergoes a vasectomy ... and then after tests is told that he is sterile, cannot know that he is still fertile ... until either his wife becomes pregnant or he is shown to be fertile by further testing.”); Gaddis, 417 S.W.2d at 578 (“it is often difficult, if not impossible, to discover that a foreign object has been left within the body within the statutory period of limitation”); International Bankers, 368 S.W.2d at 580-581 (disinterested directors could not discover certain corporate self-dealing); Ruebeck, 176 S.W.2d at 739 (homeowner could not discover faulty construction of roof); Sherman v. Sipper, 137 Tex. 85, 152 S.W.2d 319, 321-322 (Tex.1941) (allegedly fraudulent deed was available for perusal by attorney of illiterate plaintiff); Houston Water-Works, 8 S.W. at 37 (cut into plaintiffs building not discoverable until walls cracked). The common thread in these cases is that when the wrong and injury were unknown to the plaintiff because of their very nature and not because of any fault of the plaintiff, accrual of the cause of action was delayed. To be “inherently undiscoverable”, an injury need not be absolutely impossible to discover, else suit would never be filed and the question whether to apply the discovery rule would never arise. Nor does “inherently undiscoverable” mean merely that a particular plaintiff did not discover his injury within the prescribed period of limitations; discovery of a particular injury is dependent not solely on the nature of the injury but on the circumstances in which it occurred and plaintiffs diligence as well. An injury is inherently undiscoverable if it is by nature unlikely to be discovered within the prescribed limitations period despite due diligence. Computer Associates, 918 S.W.2d at 456. We have also considered the “objectively verifiable” element of the rule in a number of cases. In Gaddis, a patient claimed that her doctors were negligent in leaving a sponge inside her body after surgery. The presence of the sponge in her body — the injury — and the explanation for how it got there — the wrongful act — were beyond dispute. The facts upon which liability was asserted were demonstrated by direct, physical evidence. In contrast, Robinson involved a claim by a patient against his doctors for misdiagnosis of his back condition. We summarized the issue this way: Plaintiff, to prove his cause of action, faces the burden of proving both a mistake in professional judgment and that such mistake was negligent. Expert testimony would be required. Physical evidence generally is not available when the primary issue relevant to liability concerns correctness of past judgment. Unlike Gaddis v. Smith there exists in the present case no physical evidence which in-and-of-itself establishes the negligence of some person. What physical evidence was to the cause of action alleged in Gaddis v. Smith, expert testimony is to the cause of action in the present case. Even the fact of injury is a matter of expert testimony. 550 S.W.2d at 21. Expert testimony, we concluded, did not supply the objective verification of wrong and injury necessary for application of the discovery rule. We have adhered to the requirement of objective verification fairly consistently in our discovery rule cases, although we have not always emphasized the requirement because the alleged injury was indisputable. Willis, 760 S.W.2d at 643 (attorney’s error apparent in divorce decree); Nelson, 678 S.W.2d at 923 (child born with muscular dystrophy after doctor informed parents that mother did not carry muscular dystrophy gene); Weaver, 561 S.W.2d at 793 (negligent hemorrhoidectomy damaged nerves and muscles of plaintiffs rectum, causing loss of bowel control); Robinson, 550 S.W.2d at 21-22 (misdiagnosis of back condition not susceptible to objective verification); Hays, 488 S.W.2d at 414 (negligent vasectomy confirmed by subsequent pregnancy); International Bankers Life, 368 S.W.2d at 580 (stock transfer records and board meeting minutes proved officers’ and directors’ misdealing); Slay, 187 S.W.2d at 385-387 (paper trail detailed self-dealing); Ruebeck, 176 S.W.2d at 739 (improper construction and inferior underlying materials proved by examining and tearing up roof); Sherman, 152 S.W.2d at 319-321 (land title records showed defendants could not warrant good and merchantable title); Quinn, 140 S.W.2d at 438-439 (value of notes and subsequent value of property showed defendant’s misrepresentations); Houston Water-Works, 8 S.W. at 37 (misconstruction of building was apparent). In the present case plaintiff R. claims that her father sexually abused her and that she unconsciously repressed all memory of it for years. If the legal injury rule were applied, R.’s claims against S. would each have accrued on the date the alleged incident of abuse occurred. In applying the statute of limitations, however, the years of her minority are not included. In effect, then, under the legal injury rule, R. is in the same position as if her claims all accrued on her eighteenth birthday and limitations began to run on that date, expiring about four months before she filed suit. R.’s claims are therefore barred unless she is entitled to an exception to the legal injury rule. R. does not allege fraud or fraudulent concealment, nor could she. R. was not deceived into thinking that she was not being abused when she was. To the contrary, R.’s contention is that she was fully aware of the episodes of abuse, so painfully so that she repressed all memory of them for years. Thus, for accrual to be deferred the discovery rule must apply. For the discovery rule to apply, R.’s claim must have been inherently undiscoverable within the limitations period and objectively verifiable. We have twice held a fiduciary’s misconduct to be inherently undiscoverable. Willis, 760 S.W.2d at 645 (attorney); Slay, 187 S.W.2d at 394 (trustee). The reason underlying both decisions is that a person to whom a fiduciary duty is owed is either unable to inquire into the fiduciary’s actions or unaware of the need to do so. Willis, 760 S.W.2d at 645 (“Facts which might ordinarily require investigation likely may not excite suspicion where a fiduciary relationship is involved.”); Slay, 187 S.W.2d at 394 (knowledge of facts did not cause trust beneficiaries or co-trustees to suspect wrongdoing by other co-trustees). While a person to whom a fiduciary duty is owed is relieved of the responsibility of diligent inquiry into the fiduciary’s conduct, so long ás that relationship exists, when the fact of misconduct becomes apparent it can no longer be ignored, regardless of the nature of the relationship. Because parents generally stand in the role of fiduciaries toward their minor children, see Thigpen v. Locke, 363 S.W.2d 247, 253 (Tex.1962), R. was not obliged to watch for misconduct by her father as long as she was a minor. Again, however, R. does not claim to have been misled. Nevertheless, given the special relationship between parent and child, and the evidence reviewed in detail below that some traumas are by nature impossible to recall for a time, we assume without deciding that plaintiff can satisfy the inherent undiscovera-bility element for application of the discovery rule. We therefore focus on the second element of objective verifiability. The question is whether there can be enough objective verification of wrong and injury in childhood sexual abuse cases to warrant application of the discovery rule. To answer this question, we look first at the facts of this case and then at the general nature of such cases. II In reviewing a directed verdict, we examine the evidence in the light most favorable to the person suffering an adverse judgment. Henderson v. Travelers Ins. Co., 544 S.W.2d 649, 650 (Tex.1976). Here that is the plaintiff, R. If the question to be decided were whether R. raised a material fact issue that she was entitled to have the jury resolve — such as when she knew or reasonably should have known of the claimed abuse — we would limit our consideration to the evidence in her favor and discard all contrary evidence and inferences. Id. However, as our focus is on a legal issue — namely, the applicability of the discovery rule in this context — we consider all of the evidence adduced at trial, viewing it, nevertheless, as much in R.’s favor as the record allows. From this perspective, the evidence is as follows. S. was bom in 1942. He received a B.A. degree and an M.B.A. degree, entered the U.S. Army as a commissioned officer, and served eighteen months in the medical corps in Vietnam. In March 1970, a few months after his discharge from the Army, S., then 27, married B., then 22, who had received her B.A. degree in elementary education and had just begun teaching when she met S. Neither had previously been married. Shortly after the birth of their first child, R., on October 15, 1970, S. was fired from his job, and the family moved to Texas. S. and B.’s only other child, H., was bom in August 1975. While S. testified that he considered B. a good sexual partner for most of their marriage, B. testified that she felt early on that S. had become dissatisfied and that the problems were hers more than his. B. specifically recalls S.’s wanting to tie her hands while being intimate, something she particularly disliked. Though S. and B. each characterize the problems differently, it is fair to say that their sexual relationship deteriorated slowly but steadily after R. was bom until it ceased altogether some three to five years before the couple separated in 1989. B. and S.’s marriage was also adversely affected by S.’s inability to remain employed. B. felt S. was mostly to blame for being terminated from one job after another; S. attributed his misfortune to changes in his employers’ businesses. B. had sufficient income to support the family from a large trust set up by her father. Eventually she provided S. an office from which he conducted a commercial real estate business. While he appears to have worked diligently at the business, he was largely unsuccessful. S. and B. agree that after B.’s parents died in 1978 and 1979, their marriage began a steep decline. From all outward appearances, however, they seemed a model family. R. and H. were bright, well-behaved children. They attended a private girls’ school. R. was at least an average student and her teachers liked her. She was a class officer in junior high school. In high school, she was awarded several prizes for citizenship, won speech contests, and was active in community service. In fact, R. graduated with over 500 hours of community service, more than any other senior at her school. Much of her work was devoted to tutoring children with learning disabilities and serving food to the homeless. R. expressed interest in the subject of incest. She participated in an improvisational theater group for teenagers, taking part in a sketch dealing with incest. In 1988, her junior year in high school, she wrote a term paper on father-daughter Incest. Citing several books on the subject, the paper described the impact of incest on the victim daughter, the abusing father, and innocent family members. R. worked on another paper on incest her freshman year of college. R. considered her relationship with her own father growing up as satisfactory but somewhat distant. S. was not, in her view, comfortable showing affection, and S. admits that this was true. R. recalls that S. hugged her only occasionally and never kissed her on the cheek or forehead, as a father might. She felt that when she was a little girl she could never sit in his lap and be close. He came to her school whenever parents were invited but never seemed very interested. Once, she recalls, he approached her at a school event and shook her hand, which she thought was silly. S. seemed cold to R., expressing no emotion and little or no interest. He was, she testified, “just there”. H. shares essentially the same view of her father. By contrast, R.’s relationship with her mother was very close. In college, R. came to believe that she and her mother were “enmeshed”, a term R. and her counselor used to refer to an overly dependent relationship. Until she left high school, R. was very dependent on B. And B. was very protective of her daughters, watching them, she said, “like a mother hawk” and even spying on them occasionally to make sure they were all right. R. dated several young men in high school and college. None of these relationships included sexual intercourse, but several did involve other sexual activities. She recalls being tied up during one encounter, although she does not remember whether that was her idea. In January 1989, as R. was nearing the end of her high school senior year, S. and B. separated. B. and the girls stayed in their home, and S. moved in with his mother. In July, B. filed for divorce. R. was very angry with her parents for divorcing and sought counseling from a psychiatrist during the summer. She looked forward to getting away to college out of state, and as it turned out, she very much enjoyed her freshman year. She kept a diary in which she expressed how glad she was to be maMng her own decisions. She again involved herself in community service and still maintained the necessary grade point average to rush and join the sorority she wanted. At the end of her first year she returned to Dallas. On May 18,1990, B. told R. that she, B., had been sexually abused as a child. B.’s first recollection of her own experiences had come to her a year earlier during an annual physical examination administered by her physician. She remembers that he asked her without warning, “Who sexually abused you as a child?” Instantly she recalled two instances, both involving her mother’s father, that she had never before remembered. On one occasion, when she was 12 or 13 years old, her grandfather came into the kitchen partially exposed, and she picked up a knife and said, “No!”, or, “Stay away!” Her grandfather did not do anything. The other incident she recalled was this: T was ucjjjg — j was tied to a wrought iron bed and I had pink shorts on, and he had pulled them down. And he was standing at the foot of the bed and he had a razor strap, a leather razor strap, and he always used a straight-edged razor, and he was sharpening the razor on the razor strap and he was just looking at me and laughing at me. He didn’t do anything. He just laughed. B. never recalled any other instances of this nature in her childhood. Two days after B. shared these memories with R., R. wrote in her diary: It has been very hard learning that my mother is an incest victim. It has been very interesting to watch her slowly recall some of the many things that happened to her. It is amazing how the mind is truly able to erase things like this from the mind!! In many ways I am scared to find out more. A few weeks later R. went to see Alice Frazier, a licensed profession.! counselor whom B. had been seeing for some ume. B. had continued to see various counselors since R.’s birth to cope with problems in her sexual relationship with S., her concerns about his inability to hold a job, weight problems, and various physical problems. R. was mainly seeking help in breaking up with her longtime boyfriend. Frazier told R. that her boyfriend was more like a father to her, saying, “Sounds like incest to me.” R. also discussed other problems with Frazier, including her growing anger toward her father over the divorce. R. was concerned that her parents had not yet settled the divorce and that their financial problems were jeopardizing her returning to college. R. told Frazier that she had become aware of her first feeling of “dissociation” (a term we discuss in detail below) while talking about the divorce at a lawyer’s office, where she became “very rageful at S.’s demands”. R. described her extreme fear of sexual intimacy despite her interest in dating. Frazier commented in her notes that R.: “Sees some relationship with father. Very resistant to working on anything to do with S.” In ten meetings with Frazier over the summer, R. never mentioned that she might have been sexually abused. Her parents’ divorce did not prevent R. from returning to college in the fall of 1990. She asked her father to drive her there, and he did. In the weeks that followed S. began to call R. at college and even sent her cards and flowers. R. found this attention very disturbing, and she asked him to stop, but he persisted. The emotional stress of the divorce and her father’s attentions began to take its toll on both her studies and her social life. Just before Thanksgiving, R. had her first image of incest. She testified that she had been napping in her room and was kind of half asleep and half awake, and was dreaming. And I had this dream of this authority — this man, but it was an authority figure — and he didn’t have a face, it was just this, it was just that authority figure over this young girl. And he was forcing himself upon her. And it wasn’t all real clear, it was a dream. The girl just had kind of brownish, blondish hair, kind of long, and as I r-clr. :he man didn’t have a face. At first R. assumed the little girl was her. mother, but then she began to feel what the little girl must have felt. She did not recognize the faceless man at the time, and never has. R. called Frazier and told her about the dream. Frazier suggested that they meet at Thanksgiving while R. was home. During that meeting R. told Frazier that she believed the dream had something to do with her father. Frazier had her lie on the floor, breathe deeply, and say whatever crossed her mind. Frazier refers to this as “imagery work” or free association. R. testified: “I had this, just this picture of myself and my dad and we were sitting on the edge of the bed in his room and he just had his hand on my chest, like inside my blouse. That was all.” Later the same day R. was trying to do homework when she started writing about the little girl she had seen in her first dream. The little girl was three or four years old, and her father was forcing her to touch his genitals, telling her that she was loving him and making him feel good. As she wrote, R. realized that she was the little girl and S. was the father. A week or so later R. met with her mother and sister in Frazier’s office and told them what she had recalled. B. and H. knew nothing to indicate that S. had abused R., and they found it hard to imagine, but they nevertheless believed R. Knowing the family as she did, Frazier was surprised by R.’s account of abuse, but as their discussions continued, Frazier also became convinced R. was telling the truth. As the days passed, R. continued to recall other instances when S. had abused her. Outraged that S. was demanding visitation with H., and concerned that he would abuse her, too, R. intervened in her parents’ divorce proceeding on February 19,1991. The divorce settled several months later with S. being allowed to visit H. only when she wished, but R. persisted in her action against S. As her memories flooded back, R. became increasingly dysfunctional. She did not return to college until January 1992 but remained at home with her mother and sister. She continued to meet with Frazier and began seeing a psychiatrist. Eventually R. recalled numerous instances when S. forced her to engage in a variety of sexual contacts. She also recalls that S.’s father fondled her. The memories R. took longest in recalling were of the two occasions S. had intercourse with her. The first time she was at home with her family on her seventeenth birthday, in October 1987. The second time was in a motel room in August 1990, when S. had driven R. back to college for the start of her sophomore year. Although R. was nearly twenty years old at the time, and began to recall instances of abuse three months later, she had no memory of the occurrence until shortly before trial, which took place in June 1992. (R. does not include the August 1990 event in her allegations in this case. In her pleadings she specifically limited the period for which she is claiming damages to 1973-1988, and she does not seek recovery for any abuse that occurred within two years of her filing suit.) At trial, R.’s experts explained how she could have been abused so often for so long without remembering anything until November 1990. They attributed the phenomenon to two psychological defense mechanisms— dissociation and repression — which we discuss more fully in Part IV. As explained by the experts at trial, dissociation is the segregation of part of a person’s mental process from the rest of it, so that certain ideas or experiences are removed from the main stream of consciousness. See Robert J. Campbell, Psychiatric Dictionary 211-212 (6th ed. 1989). Repression, according to the experts, is an active banning from consciousness of things that are unacceptable. See id. at 546-547. Repression blocks all memory of a traumatic event until the mind is prepared to cope with it. The experta testified that because S.’s abuse was so traumatic, she insulated herself first by being mentally “absent” while it was happening, and then by blocking all memory of it. Although the experts indicated that the distance R. felt toward her father growing up could be attributed to her unconscious awareness of his abuse, she was never actually aware of why she felt the way she did. R. is convinced that she engaged in certain sexual activities with her boyfriends because of her experiences with her father. The experts also testified that R.’s study of incest in high school and college and her enjoyment in having her hands tied during a sexual encounter with her boyfriend were examples of repetition compulsion — an unconscious desire to repeat what her father had done to her in a setting in which she did not fear it. Despite this acting out, the experts agreed that R. was not consciously aware of S.’s abuse until November 1990. Frazier, the counselor who helped R. recover her memories, based her therapy on the treatment for post-traumatic stress disorder. In more than seventy sessions with R., Frazier encouraged her to recognize that her symptoms were based on a trauma, then re-experience the trauma, and then “own” the experience. Frazier considered that it was her responsibility, not to attempt to verify R.’s recollections, but to provide R. a safe place in which to remember them. Although Frazier never hypnotized R., she had her relax and recount whatever came into her head, a technique Frazier described as similar to hypnosis. Frazier also used a technique’ she called “guided imagery”: she would read aloud memory fragments R. had written down earlier, and R. would fill in other recollections. Frazier had R. write down her dreams and then helped her interpret them. Frazier also instructed R. to write questions about her experiences with one hand and answers with the other. Switching hands, Frazier testified, helps a patient access her subconscious. Frazier also helped R. interpret her “body memories” — physical reactions to repressed experiences, such as episodes of gagging that Frazier considered to be indicative of forced oral sex. R. often saw herself as the little girl in her first dream. She described her recollection process like this: Well, first you remember them [i.e., abusive experiences]. It’s just like relive— like remembering — the child would write what happened to her, but it was like it happened to someone else. And so, there’s no feelings and no emotions and no body reactions connected with it. And for me, I just then kind of put it aside and then, usually it’s like three weeks to a month and a half, or, depending on the incident, three months, later that my body starts to react and go through what that little girl went through when the incident was going on. Frazier testified that she had never known a patient to have a false memory of childhood abuse and did not believe that it happened. Two other experts who testified for R., Dr. Madigan, a psychiatrist, and Dr. Powitsky, a forensic clinical psychologist, acknowledged that patients sometimes have false memories, but they were both convinced, for several reasons, that R.’s recollections were valid. First, her symptomatology was consistent with that of other survivors of childhood sexual abuse: headaches, gastrointestinal problems, fatigue, nightmares, low self-esteem, depression, anxiety, body memories, gagging, distraction, fear of sexual intercourse, and lack of emotion in recounting memories. All three experts diagnosed R. as suffering from post-traumatic stress disorder, the symptoms of which include all-pervading fear, anxiety, depression, intrusive thoughts, memories, flashbacks, mood swings, feelings of helplessness and confusion. However, the experts admitted that all of R.’s symptoms could have been caused by something other than child abuse. Second, the Minnesota Multiphasie Personality Inventory test administered to R. showed a classic “V” profile, shared by many survivors of sexual abuse. The experts admitted, however, that the test was not conclusive of abuse. Dr. Powitsky also noted that R. has traits of a borderline personality disorder, although she does not have that disorder. People with this disorder, he testified, are prone to distort the truth. Third, the MMPI, administered several times to S., and his Millón Clinical Multiaxial Inventory test, showed traits similar to those in sexual offenders: narcissistic traits like self-centeredness, overvaluation of self, high need for recognition, and a high need for control; reality distortion; and problems in his ability to express emotions, especially negative ones. However, Dr. Powitsky admitted that S. did not fit other profiles of sex offenders, that the tests had some contradictory results and did not show him to be a sex abuser, and that even if S. had fit the profile of a sex offender perfectly it did not mean that he had abused R. Further, one of S.’s personality tests showed no sexual deviancy, and his penile plethysmograph — a test for determining what subjects cause arousal in a man — revealed a “flat affect” indicating no arousal at all. On the other hand, while S. told Dr. Powitsky that he had not abused R., he also asked whether it was possible that he could have done it and not remembered. Finally, all three experts noted the consistent, vivid details of R.’s memories. They were each convinced that R. could not have made up the events she claimed to recall. Dr. Madigan testified that R. did not appear to be the sort of person who was highly suggestible or who could be brainwashed. As Dr. Powitsky confirmed at trial, R. would “have to get an Oscar to give those details if they weren’t true.” S. denies that he ever abused R. in any way, and testified specifically that he never did any of the abusive things R. had accused him of doing. Neither S. nor anyone else in the family ever used drugs, or used alcohol to excess. B. testified that she had never seen S. abuse R., and that given her strong interest in protecting her daughters, it was hard for her to imagine how S. could have done what R. claimed he did for fifteen years in their three-bedroom homes without her ever once finding out. H. stated that S. had never abused her and that she had never seen him abuse R. However, B. and H. both testified that they believed R. unequivocally. Ill R. sued S. for negligence “[djuring the years 1973 through 1988, inclusively,” in engaging or attempting to engage in sexual acts or contacts with her, and exposing himself to her while he was nude and aroused. She alleged that S.’s negligence was a breach of her right to privacy and caused her damages not in excess of $10 million. (The record does not reflect why R. alleged negligence rather than an intentional tort. One reason, presumably, would be to claim coverage under S. and B.’s homeowners’ insurance policy. See Boyles v. Kerr, 855 S.W.2d 593, 601 (Tex.1993).) As we have already explained, R.’s claims were subject to the two-year statute of limitations which did not begin to run until R.’s eighteenth birthday, October 15, 1988. R. has not complained of any occurrence after her eighteenth birthday. R.’s claims were thus barred by limitations after October 15, 1990, more than four months before she filed suit. She pleaded, however, that she was entitled to the benefit of the discovery rule. Trial commenced to a jury. At the close of plaintiffs case, S. moved for directed verdict on two grounds: that the discovery rule did not apply and R.’s action was therefore barred by limitations as a matter of law; and that R. had failed to offer any evidence of sexual abuse. The district court granted S.’s motion without explanation and rendered judgment accordingly. The court of appeals, by a divided vote, reversed the judgment of the district court and remanded the case for further proceedings. 880 S.W.2d 804. In a brief opinion, the appeals court held that application of the discovery rule was controlled by its en banc decision two months earlier in L.C. v. A.K.D., No. 05-92-02867-CV, 1994 WL 59968, — S.W.2d -(Tex.App.-Dallas Mar. 1, 1994, no writ) (en banc). In L.C., plaintiff claimed that her father had oral sex with her in 1959, when she was two years old, and that he had intercourse with her in 1966, when she was nine. Twenty-five years later, on December 24, 1991, plaintiff filed suit against her father. She asserted that while undergoing psychological treatment in 1988 and 1989 she was asked whether she had been a victim of incest or other sexual abuse. At the time she did not think she had been, but the questions made her suspicious. In her lawsuit she alleged that she repressed all memory of the abuse until February 1, 1990. Defendant moved for summary judgment on three grounds: that the discovery rule did not apply and plaintiffs claim was barred by limitations; that even if the discovery rule applied, plaintiff knew or should have known of her claims more than two years before she filed suit; and that there is no cause of action for the acts plaintiff alleged. The district court granted summary judgment without specifying the grounds. After hearing the case en banc, the court of appeals, by a vote of eight to five, reversed. In a plurality opinion, six justices looked first to the law of other jurisdictions, both caselaw and statutes. The plurality summarized: From our review of the law in other jurisdictions, it is clear that courts have moved more cautiously than legislatures in this area. Courts have split almost evenly on the issue now before us and, for the most part, have declined to apply the discovery rule when no suppression of memory is alleged. The presence or absence of corroborative evidence of the plaintiffs allegations has often been critical to these decisions. Id. at *5, at -. The plurality concluded that the “overwhelming trend” among state legislatures had been to apply the discovery rule in childhood sexual abuse cases, although it noted that in following this pattern the Oklahoma Legislature, heeding concerns expressed by its supreme court, had also required objective, verifiable evidence of both abuse and repression of memory. Concerning Texas law, the plurality stated: In determining whether to apply the discovery rule, Texas courts have been most concerned with (1) the presence of documentary or physical evidence to support the claim, which alleviates concerns about stale and fraudulent claims, and (2) the injustice of requiring an injured party to bring suit before discovering the injury. Id. The plurality concluded that these two factors should be weighed against one another, and that the balance in that case favored the plaintiff. The plurality also considered that the special relationship between parent and child justified application of the discovery rule. The plurality added, however, that it was “mindful of the tremendous evidentiary problems presented by claims based on events that occurred decades ago in which there may be no physical evidence of the abuse.” Id. Consequently, the plurality held “that as a prerequisite to application of the discovery rule, a plaintiff must present objective evidence of the fact of the abuse and resultant, continuous suppression of memory of the abuse until discovery.” Id. The plurality concluded that the necessary objective evidence was supplied by the expert testimony of plaintiffs psychiatrist describing the symptoms of childhood sexual abuse and resultant memory repression, describing plaintiffs therapy through which her memory emerged, diagnosing plaintiff as suffering from post-traumatic stress disorder, and explaining the general symptoms and memory repression associated with PTSD. Id. at *5-*6, at -. Two justices concurred in the plurality’s conclusion that the discovery rule should apply but disagreed that plaintiff should be required to produce objective evidence of abuse and repression in response to a motion for summary judgment. The concurring justices also disagreed that a psychiatrist’s opinion could qualify as objective evidence. The concurring opinion is not clear on whether plaintiff should be required to adduce objective evidence of abuse and repression at trial. Id. at *7, at - (Maloney, J., concurring). Five justices dissented, arguing that this Court’s decision in Robinson rejected expert testimony as sufficient evidence of wrong and injury to justify application of the discovery rule. These dissenters concluded that absent physical evidence of abuse plaintiffs claim was too uncertain to avoid the bar of limitations. Id. at *9-*10 at - (Barber, J., dissenting). One of the dissenting justices also joined in the concurring justices’ views that plaintiffs burden to avoid summary judgment should not be increased, and that a psychiatrist’s testimony is not objective evidence. Id. at *8 at - (Kinkeade, J., dissenting). The decision of the court of appeals is not entirely clear from its opinions. Eight of the thirteen justices would apply the discovery rule in childhood sexual abuse eases. It appears, however, that ten justices would require objective evidence of abuse before applying the discovery rule, and that seven would not recognize expert testimony as objective evidence. The balancing test formulated by the court of appeals plurality — weighing the availability of objective evidence against the injustice of requiring that suit be filed before injury is discovered — does not correctly state Texas law. As we have already noted, for the discovery rule to apply a plaintiffs claim must be inherently undiscoverable and objectively verifiable. The concern that meritorious claims will be barred is already taken into account in fashioning these two elements. The two elements strike the proper balance between the beneficial purposes of statutes of limitations and the real concern that a person’s rights may be cut off. To reweigh this concern, which is of course a legitimate one, against the very balance it has produced would be to make it the determinative factor. As we stated in Robinson, the “preclusion of a legal remedy alone is not enough to justify a judicial exception to the statute. The primary purpose of limitations, to prevent litigation of stale or fraudulent claims, must be kept in mind.” 550 S.W.2d at 20. Allowing late-filed claims that are inherently undiscoverable while requiring objectively verifiable injury reduces the likelihood of injustice in cutting off valid claims while affording some protection against stale and fraudulent claims. The only physical evidence to support R.’s allegations consists of her symptoms and to a lesser extent her behavioral traits, as described by her and the experts who testified on her behalf. In every instance this evidence was inconclusive. The experts testified that R.’s symptoms could have been caused by other things than sexual abuse by her father. While R. fit a behavioral profile for someone who has been sexually abused, the experts acknowledged that that did not mean she had actually been abused. Tests on S. were also inconclusive. While he had many of the characteristics of a sex abuser, he did not match a characteristic profile, and even if he had, it would not prove that he abused R. Thus, there is no physical or other evidence in this case to satisfy the element of objective verifiability for application of the discovery rule. The kinds of evidence that would suffice would be a confession by the abuser, e.g. Meiers-Post v. Schafer, 170 Mich.App. 174, 427 N.W.2d 606, 610 (1988); a criminal conviction, e.g. Petersen v. Bruen, 106 Nev. 271, 792 P.2d 18, 24-25 (1990); contemporaneous records or written statements of the abuser such as diaries or letters; medical records of the person abused showing contemporaneous physical injury resulting from the abuse; photographs or recordings of the abuse; an objective eyewitness’s account; and the like. Such evidence would provide sufficient objective verification of abuse, even if it occurred years before suit was brought, to warrant application of the discovery rule. Although we indicated in Robinson that expert testimony would not alone provide the objective verification of a claim necessary to invoke the discovery rule, we have not held that such testimony can never suffice, at least in connection with other evidence, such as the symptoms of a survivor of abuse. We have held only that the bar of limitations cannot be lowered for no other reason than a swearing match between parties over facts and between experts over opinions. It is quite possible that recognized expert opinion on a particular subject would be so near consensus that, in conjunction with objective evidence not based entirely on the plaintiffs assertions, it could provide the kind of verification required. That is not true in this case, but we must explain why. IV Dr. Madigan, a psychiatrist who examined R. and testified at trial on her behalf, stated that psychiatry is not an exact science. Recognizing the reality of false claims of sexual abuse and the danger they pose to innocent people, Dr. Madigan told the jury: “I think it’s a tremendous burden for everybody in this room to figure it out.” Dr. Madigan accurately characterized the problems of trying to determine whether childhood sexual abuse has occurred when the victim has repressed all memory of it for a long period of time. The scientific literature on memory in general and recovered memory in particular establishes the wealth of uncertainty about these subjects. There is some agreement among psychiatrists concerning psychiatric treatment in this area. See American Psychlatric Ass’n, Statement on Memories of Sexual Abuse (1993), reprinted in 42 Int’l J. Clinical & Experimental Hypnosis 261 (1994) [hereinafter Memories of Sexual Abuse]. But there is little agreement on the validity of recovered mem-ones or on the techniques used to retrieve them. Researchers and therapists view the question of repressed memory from disparate vantage points, and with strong disagreements about the phenomena. E.g., John G. Watkins, Dealing with the Problem of “False Memory” in Clinic and Court, 21 J. Psychiatry & L. 297 (1993). The schism between the controlled world of the laboratory and the working theories of practice demonstrates that science has simply not evolved to the point that it can give definite guidance in determining whether childhood sexual abuse has occurred in a particular instance. There is basic agreement about the workings of the memory process. The senses register an event; these sense images are organized into meaningful units; the organized images are stored or “encoded” in the brain’s neural structure; and finally, memories are retrieved and recounted. See Memories of Sexual Abuse, supra, at 261-262; Michael D. Yapko, Suggestions of Abuse: True and False Memories of Childhood Sexual Abuse 66-71 (1994); Australian Psychological Soc’y, Bd. of Directors, Guidelines Relating to the Reporting of Recovered Memories § C.I. (1994) [hereinafter Reporting of Recovered Memories]; Elizabeth Loftus & Katherine Ketcham, The Myth of Repressed Memory: False Memories and Allegations of Sexual Abuse 75 (1994). See also Roberta L. Klatzky, Human Memory: Structure and Processes 2-9 (2d ed. 1980). People commonly recall little from the first five to seven years of life, and very infrequently anything before the age of two or three, principally because the brain has not matured sufficiently to assimilate and carry forward meaningful memories. E.g. Yapko, supra, at 77. See also Donald P. Spence, Narrative Truth and Putative Child Abuse, 42 Int’l J. Clinical & Experimental Hypnosis 289, 293-295 (1994). Explicit, or declarative, memory refers to the ability to consciously recall events or facts. Memories of Sexual Abuse, supra, at 262. Implicit, or procedural, memory is behavioral knowledge of an experience without conscious recall. Examples of the latter are knowing how to ride a bicycle and a combat veteran’s feeling of panic upon hearing helicopters without remembering specifically the helicopter crash that killed a friend. Id. These two types of memory appear to be supported by different brain systems. Id. Some have posited that procedural memory may remain after declarative memory of the event that generated it has vanished. See Matthew H. Erdleyi, Repression, Reconstruction, and Defense: History and Integration of the Psychoanalytic and Experimented Frameworks, in Repression and Dissociation: Implications for Personality Theory, Psychopathology, and Health, 1, 16 (Jerome L. Singer ed. 1990) [hereinafter Repression and Dissociation]. Procedural memory could therefore play a role in tending to confirm or belie an accusation of abuse. The problem, of course, is that a certain type of procedural memory, like gagging, may indicate child abuse, but the fact that a person gags does not indicate why; it does not eliminate all other possible causes except abuse. Thus, procedural memories may be misinterpreted by a patient or therapist, and that misinterpretation may solidify into “truth”. Memory is a multifarious, complex, usually reconstructive process. It does not retrieve information the way a video recorder or computer does. Everything sensed is not stored; recall of picture-perfect images is not automatic. A variety of social, psychological, and developmental factors commonly cause distortions at each stage of the process. Memories of Sexual Abuse, supra, at 26
