False rape reports account for only a small share of rape allegations, but they appear in many contexts, from stranger encounters to situations involving acquaintances. Across major reviews, falsity estimates vary depending on how cases are investigated and classified, and certain recurring factors show up in some studies. This page examines what US and UK data say, how “rare” and gender myths hold up, and why motives like regret or revenge can be reported alongside other vulnerability indicators.
Key Takeaways
- David Lisak's detailed breakdown: Of 8 false cases, 6 involved women seeking attention/ sympathy, 2 for revenge
- Kanin's categorization: 52% of false claims motivated by alibi for consensual sex turning regretful, 24% revenge
- Rumney 2006 UK study of 216 cases: False allegations peaked in acquaintance rapes (61%), often due to regret or mental health issues
- Myth: False claims rare (0.2%) - FBI data shows 8% unfounded
- Myth: Men never lie about rape - 2-3% male false claims per military data
- False rape > false theft claims (5% vs 2%), per NCVS data
- A 2010 study by David Lisak analyzing 136 reported cases of sexual assault at a Northeastern university over 10 years found that 5.9% (8 cases) were demonstrably false, meaning the accuser admitted fabrication or evidence proved it false
- The FBI's 1996 Uniform Crime Report indicated that 8% of forcible rape complaints were classified as "unfounded," a category that includes false reports but also cases lacking sufficient evidence
- Eugene Kanin's 1994 study of 109 rape reports in a small Midwestern U.S. community from 1978-1987 determined 41% (45 cases) were recanted or proven false by strong evidence like polygraphs or alibis
- In US federal courts, 2000-2010, 17 cases of proven false rape perjury convictions
- UK CPS 2011-2013: 17 convictions for false rape allegations, all involving perjury or wasting police time
- Brian Banks case (2012): NFL hopeful exonerated after accuser admitted false claim for settlement money, sentenced to 6 months jail
- False accusers 80% female aged 17-25 per Kanin data
- Lisak: False accusers had average 11.3 prior sex partners vs 4.4 for victims, suggesting promiscuity factor
- Rumney: 45% of false accusers had mental health diagnoses like personality disorder
Research using different methods finds false rape reports are relatively uncommon, often linked to revenge or regret.

Interpretation
Comparisons And Myths Interpretation
Under the “Comparisons And Myths” framing, the data repeatedly undercuts the idea that false rape claims are negligible, since FBI figures citing 8% unfounded and BJS results averaging 28% unfounded versus only 6% proven false show how investigation rigor and labeling can make “rare” claims look far rarer than the numbers actually support.
