We study dangerous speech and ways to counteract it.

People don’t commit violence against other groups - or even condone it - spontaneously. First they must be taught to see other people as pests, vermin, aliens, or threats. Malicious leaders often use the same types of rhetoric to do this, in myriad cultures, languages, countries, and historical periods. We call this Dangerous Speech. Violence might be prevented by making it less abundant or less convincing. We work to find the best ways to do this – while protecting freedom of expression.



This guide - updated for 2019 - provides an in-depth exploration of dangerous speech and how to identify it, dangerous speech on the internet, and some promising efforts to reduce the harmful effects of speech.
