False accusation of rape

Although there are widely varying estimates of the prevalence of false accusation of rape, according to a 2013 book on forensic victimology, very few reliable scientific studies have been conducted.

[9] According to Hines and Douglas (2017), 73% of men who've experienced partner-initiated violence reported that their partner threatened to make false accusations.

[30] According to the Globe and Mail, the statistics about unfounded cases are often kept secret, providing no incentive for police forces to analyze and account for them.

[33] Researchers Cassia Spohn, Clair White and Katharine Tellis examined data provided by the Los Angeles Police Department in the US from 2008, and found that false reports among rape cases was about 4.5 percent.

[18] Upon review of Cassia Spohn's work, the Los Angeles District Attorney's Office (LADO), which initially collaborated in the report, concluded "the perspective, conclusions and policy recommendations are inconsistent with American constitutional principles of justice, due process protections and the ethical obligations of prosecutors."

The LADO noted that Spohn et al. likely had ideological biases against the accused and "failed to develop an understanding of the criminal justice system in Los Angeles County.

"[18] A report by the Crown Prosecution Service (CPS) examined rape allegations in England and Wales over a 17-month period between January 2011 and May 2012.

[34] He added that the report also showed that a significant number of false allegations of rape (and domestic violence) "involved young, often vulnerable people.

"[35][36][37] David Lisak's study, published in 2010 in Violence Against Women, classified as demonstrably false 8 out of the 136 (5.9%) reported rapes at an American university over a ten-year period (1998 to 2007).

[24] A separate report by the same researchers that year which studied primary data from several countries in Europe, including Austria, Belgium, England, France, Germany, Greece, Hungary, Ireland, Portugal, Scotland, Sweden, and Wales, found the average proportion of reports designated by police as false was about 4%, and wasn't higher than 9% in any country they studied.

[25] The UK Ministry of Justice in their Research Series published a report describing the analysis of 1,149 case files of violent crimes recorded April 2008 to March 2009.

When it came to cases with grievous bodily harm (GBH), even the broader definition (no evidence, delayed report, retraction, or intoxicated victim) accounted for only 2% of crimes.

Lisak points out that even in the original paper, Rumney concludes that many of the studies have inadequacies and should not be used to estimate the frequency of false rape reports.

In contrast, the average rate of unfounded reports for all "index crimes" (murder, aggravated assault, forcible rape, robbery, arson, burglary, larceny-theft, and motor vehicle theft) tracked by the FBI is 2%.

[22] In 1994, Eugene J. Kanin of Purdue University investigated the incidences of false rape allegations made to the police in one small urban community in the Midwest United States (population 70,000) between 1978 and 1987.

[7] He states that unlike in many larger jurisdictions, this police department had the resources to "seriously record and pursue to closure all rape complaints, regardless of their merits".

After reviewing the police files, Kanin categorized the false accusations into three broad motivations: alibis, revenge, and attention-seeking.

Kanin also investigated the combined police records of two large Midwestern universities over a three-year period (1986–1988) and found that 50% of the reported forcible rapes were determined to be false accusations (32 of the total 64).

No polygraphs were used, the investigations were the sole responsibility of a ranking female officer, and a rape charge was only counted as false under complainant recantation.

Critics of Kanin's report include David Lisak, an associate professor of psychology and director of the Men's Sexual Trauma Research Project at the University of Massachusetts Boston.

These procedures include the "serious offer", in this department, of polygraph testing of complainants, which is viewed as a tactic of intimidation that leads victims to avoid the justice process[38] and which, Lisak says, is "based on the misperception that a significant percentage of sexual assault reports are false".

He argues that the study's most significant problem is Kanin's assumption "that police officers abided by departmental policy in only labeling as false those cases where the complainant admitted to fabrication.

[55] Sacks says, the media also normalizes sexual violence in general, often blames the person who reported the assault, and commonly expresses sympathy for the alleged perpetrators instead of the victim.

As a result, the people commonly had a difficult time believing someone they know or like is a rapist, and this could contribute to the idea that the person who reported the rape is at fault.

Some behaviors associated with lying by juries is actually typical of true rapes, including kissing or a previous relationship with the rapist.

[59][60] Over a five-year period ending in 2014, a total of 109 women were prosecuted for crimes related to making false accusations of rape.

Wells found that many victims of lynching had been falsely accused of rape or some other offense because they had engaged in economic competition with white-owned businesses.

In a survey done in the 1930s of a small town in Mississippi, 60 percent of respondents stated that lynching was an appropriate response to a case of rape and that it was necessary to maintain law and order and protect white women.

One of the accusers was rumored to be "a common street prostitute of the lowest type" who had been overheard asking "negro men" about the size of their "private parts".

[65] The accusers may have told the police that they were raped to divert police attention from themselves, as not only were they potentially at risk of being charged with prostitution by local authorities, the fact they were crossing state lines placed them at risk of being found guilty of violating the federal Mann Act (which prohibits interstate transport of "any woman or girl for the purpose of prostitution or debauchery, or for any other immoral purpose").
