Can Psychology Reveal Who's Lying to the Senate Judiciary?

Psychology may be able to distinguish the truth from falsehoods in sex crimes.

The media reports that The U.S. Senate has received an FBI report on sexual misconduct allegations against Supreme Court nominee, Brett Kavanaugh, but the controversy continues over who was lying, and who was telling the truth.

Professor Christine Blasey Ford testified to the Senate Judiciary Committee that Mr. Kavanaugh and another man assaulted her in the 1980’s when they were teenagers.

Professor Christine Blasey Ford’s and Brett Kavanaugh’s emotional testimony have both come under intense scrutiny; how believable she or he appeared may determine how the public decides what really happened.

Psychologists currently approach the question of who is telling the truth in these predicaments of sexual assault and rape in a very different and surprising manner to the public, and even senior legislators.

The technique has recently been shown by the latest research to improve the ability to distinguish truth-tellers from fabricators in the arena of sexual assault.

False allegations, particularly if undetected as such, generate distress to victims and destroy lives, including unwarranted imprisonment, yet also raise unnecessary suspicion towards rape victims.

André De Zutter, a Professor at the Faculty of Law at Vrije University in Amsterdam, has pioneered a novel approach that is called ‘The theory of fabricated rape.' The technique relies on a more scientific approach to sexual assault allegations than relying on our instinctive reaction to testimony.

Zutter cites the example in the case of Gary Dotson (the first DNA exoneree in the USA); a victim of a false allegation made by Kathleen Crowell Webb, spending 10 years in and out of prison as a consequence. Webb's testimony was so powerful that even when she later recanted her allegation and confessed the truth, not everyone believed that the rape had never occurred. It was not until the advent of adequate DNA testing that Gary Dotson was fully vindicated.

But what about cases where DNA evidence cannot determine the issue, as with Brett Kavanaugh and Christine Blasey Ford, where it ends up—as it often does—as one person's word against another's? Is there still a way of getting at the truth?

Professor Zutter and his colleagues argue that a false complainant of rape or sexual assault has to fabricate a story, yet the account of a survivor is based on recollections of an actual event.

As false complainants are lying, their stories will diverge in a patterned and reliable way from the accounts of victims, so forensic scientists who have compared false testimony with true ones will be able to spot these differences.

Fabricators will also construct a narrative based on their own prior sexual experiences, and if these do not resemble rape or assault, then the fabricated version will exhibit detectable differences, compared to a true account of rape.

Deceivers will also construct a story based on their beliefs concerning rape. If the beliefs false complainants hold about rape are incorrect, then an unlikely account of rape will emerge.

André De Zutter, Robert Horselenberg and Peter J. van Koppen, the authors of the latest study based on this new theory published in the Journal of Police and Criminal Psychology, contend that it may be possible to distinguish to a considerable extent between true and false allegations of rape.

For example, a common strategy of liars is to keep the story simple and without details, so false complainants of rape or sexual assault will probably adopt the same approach and construct a more concise or abbreviated general story.

Previous research has established that a false complainant tends not to give an estimate of the duration of the rape, nor describes how she and the rapist became undressed. It has also been found that true accounts often contain significantly more utterances by the sexual or rapist offender compared to false accounts.

Researchers who studied rapists’ or victims’ accounts of rape found that if violence is used, it is often goal-oriented, so that once the goal is reached, the violence stops. The goal of violence, in the context of rape, is often to exert control over the victim. Research would suggest that extreme levels of physical brutality may be rare during the rape itself, as opposed to the moments before and after.

During a rape, research finds that the victim tends to be more concerned with survival, and thus submits to the attack with little resistance, while in false allegations, the levels of violence and resistance described by the complainants tend to be much higher.

Another difference is that a wider array of sexual acts occurs in the accounts of victims of rape. For instance, 13 of the 16 stories of victims in one study described anal intercourse and the insertion of objects. In that study, a description of sexual acts other than vaginal intercourse was only reported in 6 of the 17 stories deemed to be false or fabricated stories of rape.

Another way of distinguishing fabricators from truth-tellers comes from the way rape and sexual assault is reported by news media. Media reports will tend to underpin rape beliefs held by the lay-public and, therefore, this will emerge as a detectable difference between true (as opposed to false) accounts.

Portrayals of rape in the media are consistently atypical and generalized. As a consequence, a certain idea about sexual assault arises in the public domain and in the mind of lay people that does not correspond with the reality.

For example, pseudo-intimate behaviour is rarely described in news media, yet many rapists exhibit pseudo-intimate behaviour (like kissing). Pseudo-intimate behaviour is commonly exhibited in the context of consensual sex and mimics a caring relationship.

Laypeople tend not to believe that pseudo-intimate behaviour is exhibited by rapists.

One study found that jurors believed that an allegation of rape was false when the rape was preceded by kissing. Jurors become especially skeptical that an assault has occurred where the kissing was requested by the rapist and consented to by the victim. Jurors tended to believe that rapists would not be seeking a kiss if they intended to rape someone.

Previous research finds that rapists ask personal questions, try to uncover the identity and address of the victim, and remain with the victim longer than necessary. In 30 percent of the victim accounts studied, the rapist apologised afterwards, whereas no fabricated rapist in the stories of false complainants did. In 40 percent of the stories of victims, the rapist was friendly afterward, and in 53 percent, the rapist reassured the victim.

In the very latest study on the ‘Theory of Fabricated Rape,’ entitled ‘Detecting the True Nature of Allegations of Rape,’ a police sample of true and false allegations was studied. A total of 72 true and 57 false allegations of rape were investigated, and, using ‘the theory of fabricated rape,’ incidents were blindly categorised into true or false. ‘The theory of fabricated rape model’ was able to predict the true nature of the majority of allegations with an accuracy rate of 91 percent.

This scientific psychological approach, pioneered by academics at Maastricht and Vrije Universities in the Netherlands, could help the public and the Senate Judiciary Committee who questioned Professor Christine Blasey Ford and Brett Kavanaugh to make a better decision, less influenced by prior political or gender prejudices.

Psychological research has established that cases like these tend to be decided by us when we think we are being open-minded, but in fact, we have often already made up our minds using prior biases and prejudgments about men and women and sex.
