Crossing the Line:
Distinguishing Fantasy and Intent In Sexual Crimes

Gilberto Valle, a New York City police officer, is currently on trial for plotting to kidnap, torture, rape, kill and cannibalize women, including his wife and some of her friends. This case has drawn a great deal of media and public attention for its disturbing details, and for shining some light into the shadows of the Internet, where extreme websites are available for almost every conceivable sexual variation, including cannibalism, necrophilia, and sadism.

A key aspect of this case are computer records of Mr. Valle’s chats with others about how he would carry out his alleged plans, and a charge that he illegally accessed a law enforcement database to gain information about one of the women. Does this digital evidence indicate Mr. Valle was plotting to commit these crimes, as the prosecution has claimed, or is it evidence that Mr. Valle was expressing his sexual fantasies online, with no intention of carrying them out, as his defense has argued?

There has long been interest in the connection between fantasy and behavior in forensic and legal arenas. This has been a central question in my research and clinical work over the past 20 years. The question usually is prompted by behavior rather than fantasy: Someone commits a sexual crime – molests a child, rapes a woman – and he (the perpetrator is usually male) is arrested, prosecuted, and convicted. Psychologists or other mental health professionals are then asked to try to understand what his motivations were: Is he a pedophile, sexually attracted to young children, and acting upon that attraction? Is he sexually aroused by sexual violence? What are his sexual fantasies, and how might that translate to crimes he might commit in the future?

Pre-Internet, mental health evaluators had to infer the contents of someone’s sexual fantasies because our understanding was constrained by a simple fact: Only the perpetrator really knew what was in his mind, and he might not tell us the truth, for very understandable reasons given the legal consequences. (Who would choose to admit to atypical sexual fantasies when facing years in prison?) The Internet has changed this, so that we can now gain valuable insight into someone’s sexual fantasies and desires by examining the pornography he views online, the websites he visits, and the content of his emails, instant messages, and message board posts. Even if he denies it, evidence of persistent and repeated access to particular kinds of pornography and sexual content is indicative of his sexual interests. For example, one study my colleagues and I completed suggested a majority of men convicted of child pornography offenses would meet diagnostic criteria for pedophilia; yet we found in another study that many of these men have never sexually molested children in the past (based on criminal history and their self-report).

What then distinguishes those who express their fantasies online only, and those who also act on those fantasies in the physical world? What is the likelihood that someone will act on these sexual fantasies? Our ongoing research suggests child pornography offenders who act on their sexual interests and fantasies differ from those who do not by younger age, impulsive personality, callousness, and substance abuse. Another recent study suggested that offenders who sexually approach minors online can be distinguished into “fantasy-driven” and “contact-driven” offenders. Fantasy-driven solicitation offenders spent more time online and engaged in more protracted interactions with minors. Their main interest was sexual gratification while online, including sexually explicit chats, masturbation in front of a webcam, and exchange of pornography. The contact-driven solicitation offenders, in contrast, spent less time interacting online; their main interest was in finding minors who would be interested in meeting them in real life.

We know that some sex offenders engage in “practice” behavior, such as following children or women before they commit a sexual assault, or exposing themselves to child or female victims over a period of months or even years before committing hands-on offenses. As I discussed with Rachel Aviv, the author of a recent New Yorker piece on sexual offending, the clinical and legal challenge is determining when someone is expressing their fantasies online, and when someone is preparing to act. I was involved in a similar case where the offender had accessed child pornography and written violent, sexually explicit stories about how he planned to abduct, rape and kill his friend’s young daughter. There was physical evidence to suggest he was making the transition from fantasy to action, though he vehemently denied any intentions to act.

The same dilemmas in differentiating individuals and forecasting the future are faced in other situations involving online evidence: When is someone simply expressing his frustrations with other students and/or teachers at his school on social media, and how can we tell if he is actually working himself up to committing a mass shooting? When is someone expressing his outrage at perceived American slights in online chat rooms, and how can we tell if he is instead preparing to commit a terrorist act?

There is science to guide these determinations, but our ability to predict future behavior is imperfect. There are risk factors we can look for in clinical interviews and careful review of files – including personality traits, criminal history, and sexual history – but they are noisy correlates, and no factor is definitive: Many young, impulsive, callous, and substance-abusing men break the law, but they are very unlikely to commit sexually motivated homicides, which are fortunately quite rare. This is the central problem of criminal profiling: What is the truly distinctive feature or set of features that can help investigators find the right suspect? The same noise-to-signal problem is faced in counter-terrorism efforts, in trying to identify the truly risky individuals from the chatterers.

Decisions can be informed by scientific knowledge, but we cannot clearly and confidently mark the line between expressing fantasies online and action in the physical world: Our scientifically based opinions about risk are expressed in probabilities, not certainties. Moreover, the Internet has created a new psychological space where sexual fantasy (usually private) can be expressed in a public domain, and where the distinction between expressing fantasy and expressing intention is even further blurred. Hanging over this confusing psychological space are the serious costs for making a mistake in either direction: Incarcerating someone for “thought crimes”, no matter how heinous or abhorrent; or not intervening before something truly terrible happens.



  1. Thanks, Michael, for a very thoughtful and insightful post. I wonder if having more information (eg a computer trail) makes it any easier than it used to be to decide what to do in these difficult cases. Does knowing more make you feel any more certain, or is it the same tortuous process that I remember it being before the Internet?

  2. Emotions prefigure actions, the act being the behaviour that resolves the arousal state. For most men (and others) frustrated sexual arousal can be resolved through masturbation, which is a way of externalizing and reifying the psychological intangibles that disturb equilibrium. The act of grasping the penis in itself lends security as it gives substance to the intangible. Considering the object of desire in all it's aspects, exploring the possible, probing the unknown, these are much more than double entendres, they're essential steps to psychic health.

    However, men experiencing sexual or romantic attraction to children are not just denied scope to act, they're denied the freedom to feel and to process their feelings in fantasy. Faced with dilemmas in how to act and how to feel, they urgently need a positive culture of paedophilia, with authentic values, in which to consider, explore and probe.

    This culture needs to be a safe but robust (even ribald) framework in which to rehearse appropriate responses to forbidden desires. In fact such a framework has existed for centuries but has come under attack in recent decades, during which paedophilia has been equated with sexual abuse and representations of paedophilia have been equated with child pornography.

    So, to distinguish offenders from non-offenders, start by giving non-offenders a voice and protecting their culture of benign paedophilia from attack by bigots and puritans. It is not a predictor of child abuse, it's a vaccine against it.


  3. Excellent article differentiating the attraction from the action. What are the risk factors for someone who is sexually attracted to children that differentiate those who do not act on it from those who do offend? Is there an actuarial risk assessment instrument for those who have not offended?


  4. Excellent analysis Sean and I agree that "the culture needs a safe framework to rehearse appropriate responses" but how does one define "benign paedophilia?" Are there ways beyond internet child sexually exploitative material (Child Porn) as those images and videos are by their very nature, NOT BENIGN. If there is a demand for those images, someone will supply them thus creating more child victims...
