Varies. English sources generally give figures up to 10%. In my country, I've seen legal psychologists throw around numbers like 80% in certain contexts such as divorce cases involving child custody disputes.

Every law, no matter how well meaning, can and will be abused. Women are not saints. Be especially wary when lies could provide secondary victories such as favorable child custody outcomes.

Feminist discourse is overwhelmingly in favor of disregarding false positives: they would rather see thousands of innocent men suffer than watch a single guilty man go free. They cast a wide net and hope to catch the guilty men within it. They care not for the suffering they cause to the innocent. Quite the contrary, in fact: I've seen them try to justify it as historical reparation.
