What the Research Says About False Reports of Sexual Assault—and Why It Matters on Campus

In campus conversations about sexual misconduct, few topics are as misunderstood as false reporting. Misconceptions about how often false reports occur can influence institutional policies, shape investigations, and, perhaps most importantly, affect whether survivors feel safe reporting sexual violence perpetrated against them.

‍Research consistently finds that intentionally false reports of sexual assault are uncommon. Researchers estimate that false reports account for roughly 2% to 10% of reported cases.1 Equally important, experts caution that reports are sometimes incorrectly classified as “false” when they do not meet the legal standard for prosecution, lack sufficient evidence, or are withdrawn by the reporting party. These situations should not be equated with a knowingly false allegation.

Misclassification has significant consequences. Labeling reports as false prematurely or without evidence can distort campus data, reinforce misconceptions about sexual assault, and erode trust in institutional reporting systems. Accurate classification is essential to ensuring both fairness for all parties and confidence in the investigative process.

Several factors contribute to the persistence of the false-reporting myth. Sexual assault cases often lack eyewitnesses or definitive physical evidence, making them inherently difficult to investigate. In addition, trauma can affect how survivors recall and disclose events. As memories are processed over time, details may emerge gradually or be recounted differently, changes that can be mistaken for deception despite being documented in trauma research.2,3

Broader cultural narratives also shape perceptions of credibility. Biases related to gender, power, race, and social status can influence how reports are received and evaluated. On college campuses, these biases may lead survivors to anticipate skepticism rather than support, discouraging reporting and undermining confidence in institutional processes.

Although false reports are rare, they often receive more attention than the much more prevalent problem: underreporting. National research indicates that most college students who are sexually assaulted never report the incident to law enforcement or campus officials.4,5 Fear of not being believed, concerns about retaliation, lack of confidence in institutional responses, privacy concerns, and self-blame all contribute to low reporting rates.

Persistent myths about false reporting only compound these barriers.

For college and university leaders, the research points to several important priorities:

●       Train with precision. Ensure investigators, hearing officers, and responsible employees understand what the distinction between an unsubstantiated report and a verified intentionally false report. Accurate classification supports both due process and reliable institutional data.

●       Communicate responsibly. When discussing sexual misconduct cases or reporting trends, use language grounded in research and established definitions. Avoid statements that unintentionally reinforce myths or stigmatize survivors.

●       Adopt trauma-informed practices. Students are more likely to report misconduct and participate in institutional processes when they believe they will be treated with fairness, empathy, and respect.

●       Focus resources for maximal impact. The research demonstrates that false reports are uncommon, while sexual violence remains a significant concern on college campuses. Investments in prevention education, bystander intervention, equitable investigations, and survivor support are likely to have the greatest impact.

‍Moving beyond misconceptions about false reporting is not simply a matter of correcting the record. It’s about fostering a campus climate where reports are evaluated fairly, institutional processes are trusted, and students who are victims of sexual violence feel safe seeking help. By grounding policies and practices in evidence rather than myth, colleges and universities can better uphold equity and accountability for their students.
