Never thought of this angle:

Indeed, writers calculate that there is a greater likelihood of being attacked by a shark than being falsely accused of rape. And sticking with statistics from the United States, the National Center for Injury Prevention and Control cited in 2013 that a man is much more likely to be the victim of a rape than the victim of a false accusation.

The full article is also worth a read, not surprisingly.

Yet despite the concrete and rigorously researched data, the belief that false accusations are widespread continues to be a leading myth. Why? Perhaps it has something to do with centuries of devaluing a woman’s word on the sole count of her gender—a cultural practice that dates back to ancient times. Throughout history and in most cultures, women have habitually not been trusted; women’s words are discounted and devalued because they are not those of men. Certainly, men and boys are also rape victims—ones who, like women, all too often go unbelieved. However, when 90% of rape victims are women, there are gendered nuances to the conversation.
