Defendant Arthur Stewart Cott was charged and convicted of violating section 725.10, The Code 1977, which prohibits lascivious acts with persons under sixteen years of age for the purpose of arousing or satisfying sexual desires. The evidence at trial showed that on November 28, 1977, a five-year-old girl accompanied her mother to the Target Store on Euclid Avenue in Des Moines. They initially went to the toy department, where the girl became temporarily separated from her mother. According to the girl’s testimony, a man approached her in the toy department, asked her if she wanted a quarter and she decided that she did. The man and she then walked to the adjacent shoe department because he told her that she would find the money there on the floor. In the shoe department, the man pulled down his pants and prompted the girl to touch his genitals. The man also touched the girl’s pubic area at a time when her pants were down. Afterwards, the man gave the girl a quarter, instructing her to tell her mother that she found it.
Other evidence which trial court admitted, pursuant to its ruling on defendant’s motion in limine, was the testimony of an eight-year-old girl regarding her involvement in similar incidents with defendant. The last of those incidents, for which he was convicted, had occurred approximately sixteen months earlier in Ames. She testified that defendant and she had touched each other’s genital area a couple of times in his home and that he had twice given her money, advising her to tell her family that she found it.
In its instructions, trial court cautioned the jury that a conviction of the defendant must be based on the incident which oc *326 curred at the Target Store “and no other act.” The jury was also instructed that the evidence of the prior incidents should only be considered as it might relate to defendant’s motive on November 28, 1977, his intent, his identity as the offender and any common scheme or plan the jury might have found the defendant to have followed.
The sole error which defendant has urged on appeal was the admission of the testimony regarding the Ames incidents. The court of appeals reversed and remanded for a new trial, holding that the trial court had abused its discretion in admitting that testimony. While acknowledging that the evidence of defendant’s prior offense had probative value, the court of appeals concluded that it was outweighed by its prejudicial effect.
We subsequently granted the State’s application for further review of the decision of the court of appeals and now vacate that decision and reinstate trial court’s judgment.
I. In reviewing trial court’s exercise of discretion in admitting the testimony regarding defendant’s prior offense, we first consider the bases upon which relevance of the evidence may be found. The general rule is that “one crime cannot be proved by proof of another.”
State v. Schlak,
(1) motive, (2) intent, (3) absence of mistake or accident, (4) a common scheme or system of criminal activity embracing the commission of two or more crimes so related that proof of one tends to prove the other, (5) identity of the person charged with the commission of the crime.
State v. Folkens,
The State urges that the contested testimony falls within one or more of these well-recognized exceptions and within a sixth proposed exception: to show the lewd and lascivious disposition of the defendant. Because a cursory examination of some of our more recent opinions might yield arguable support for the creation of such an added exception in cases of this nature, we believe clarification is necessary.
This court’s allowance of evidence of pri- or offenses for the purpose of showing the lewd disposition of the defendant in cases involving lascivious acts with a child apparently originated in
State v. Neubauer,
Later,
State v. Kinkade,
Those well-known exceptions were held applicable in cases subsequent to
Kinkade.
For example,
Schlak,
As is apparent from this summary, evidence tending to prove a lewd disposition of the defendant charged with lascivious acts with a minor was originally considered relevant only insofar as it showed his intent solely toward the prosecuting witness. Almost imperceptibly, the lewd disposition exception was overextended to permit evidence of the defendant’s acts with other victims. First, in Schlak, it crept in as a synonym for motive. Then, in Maestas, it was used as an alternative rationale to the common scheme exception. However, proving lewd disposition has never been the sole purpose for which this court has approved the admission of testimony concerning prior acts with persons other than the prosecu-trix. Nor are we now disposed to endorse lewd disposition as a separate, exclusively adequate exception to the rule prohibiting the admission of testimony regarding prior victims. A focus on the criminal or aberrant disposition of the defendant with regard to various victims is exactly the sort of prejudice which the general rule seeks to avoid. By creating an exception of this kind, we would seriously erode the impact of the general rule, proscribing evidence of prior criminal conduct, in the context of sex crimes. 1 The resultant unfairness to those accused of sex crimes is self-evident. 2
*328
Because we reject the lewd disposition rationale for approving admission of the testimony in question, our task is to determine if it falls within some other, acceptable exclusion from the rule. As stated in
Wright,
Nor do we believe the evidence was admissible to show a common scheme or system of criminal activity. The fact that defendant committed crimes of the same nature against the two girls is insufficient to bring the testimony within that exception.
See Wright,
Rather, we hold the testimony was relevant here to establish the identity of the defendant as the perpetrator of the offense. Identity of the assailant was apparently the principal issue at trial. Although the prose-cutrix was able to assist in the completion of a composite drawing of a bearded assailant which bears some resemblance to defendant, picked defendant’s photograph from an array and also picked defendant in a line-up, she also incorrectly described defendant as having orange hair and facial hair. Furthermore, she stated that he was wearing blue jeans on the day of the incident when in fact it appears he had been wearing blue-and-white-striped bib overalls. Also, defendant presented alibi testimony which accounted for his whereabouts during most of the time span within which the incident allegedly occurred.
Testimony regarding the Ames incidents tended to prove the identity of defendant as the same person who committed both crimes because of the similarity of the acts involved and the method by which they were accomplished.
See Schlak,
*329
II. While we agree with trial court’s conclusion that the testimony regarding the Ames incidents was relevant, we must also decide if trial court abused its discretion in determining whether any danger of unfair prejudice created by the evidence substantially outweighed its probative value.
State v. McDaniel,
Defendant apparently contends that the admission of testimony regarding the Ames incidents was prejudicial because of an alleged paucity of other reliable evidence of defendant’s guilt. In particular, he argues that the State offered no evidence to independently corroborate the prosecutrix’s testimony and that her description of the assailant did not entirely match defendant’s appearance. He also argues that the identification procedures employed by the police “smacked” of police intent to prove defendant’s involvement and that defendant adequately established an alibi. Defendant’s argument is untenable. The weight and credibility to be given to the prosecuting witness’s testimony was a factual issue for the jury.
McDaniel,
Also enhancing the probative value of the testimony was the fact that defendant’s culpability was clearly shown with regard to the Ames incidents. His conviction for the previous crime was based upon a guilty plea.
See Johnson,
To be balanced against these indicia of probative value are the possibilities for prejudice which accompany testimony regarding a prior offense. Dean Wigmore has summarized the types of prejudice the general exclusionary rule seeks to avoid as follows:
(1) The over-strong tendency to believe the defendant guilty of the charge merely because he is a likely person to do such acts; (2) The tendency to condemn, not because he is believed guilty of the present charge, but because he has escaped unpunished from other offences; *330 . (3) The injustice of attacking one necessarily unprepared to demonstrate that the attacking evidence is fabricated .

See, also Commonwealth v. Boulden,
Because trial court’s ruling to admit the testimony cannot be termed unreasonable or an abuse of discretion, we vacate the court of appeals’ decision and affirm the judgment entered in district court.
DECISION OF COURT OF APPEALS VACATED; JUDGMENT OF DISTRICT COURT AFFIRMED.

See
Gregg,
Other Acts of Sexual Misbehavior and Perversion as Evidence in Prosecutions for Sexual Offenses,
6 Ariz.L.Rev. 212, 215 (1965). The article indicates the majority of courts apply an exception for lewd disposition only to admit evidence regarding prior acts with the prosecutrix.
Id.

supra,
§ 190 at 449-50,
See generally
22A C.J.S.
Criminal Law
§ 691(31), (35) (1961). However, it also notes the trend, represented by a minority of jurisdictions, to extend the exception to evidence regarding prior victims. Gregg,
supra
at 215. Most of the courts which have so extended the rule have done so "almost unconsciously by extending the narrow exception for similar offenses with the prosecuting witness, or else by blithely forcing such offenses into one of the standard exceptions.”
Id.
at 225. It is noteworthy that some of those courts have recently placed restrictions on such use of the exception.
See, e. g„ Lovely
v.
United States,
. The implicit assumption in treating sexual offenders differently from other criminals is that they have a greater propensity for recidivism. Most studies show this assumption unwarranted. See State v, Spreigl,
■ Also, the possibility of prejudice resulting from the admission of evidence of prior sexual offenses is certainly not less than that resulting from admission of evidence of other types of criminal behavior. In fact, it has been argued that a blanket exception for the admission of prior sexual offenses “appears extremely un *328 usual in light of the intensely emotional nature of prosecutions for sex crimes which heightens the possibility of juror prejudice.” Note, Time for Change: Evidentiary Safeguards Needed in Trials for Sexual Offenses, 11 Ind.L.Rev. 895, 895, 907 (1978).
. We note that a clinical psychologist testified at the hearing on defendant’s motion in limine in answer to a hypothetical question that the Des Moines incident revealed a greater degree of behavioral disturbance. His opinion was based on the fact that the Ames incidents involved conduct with a neighbor girl, whom defendant had known over an extended period of time, in the privacy of his home, while the Des Moines incident involved conduct with a stranger in a public place. However, the expert also testified that there was some likelihood that the same individual committed both offenses and that the likelihood increased if his condition had deteriorated in the interim.
