Vigilante violence, often targeting religious and sectarian minorities and preceded by unsubstantiated rumors, has taken the lives of many citizens in India and Pakistan in recent years. Despite its horrific nature, such vigilantism receives popular support. Can reducing the credibility of rumors via corrections decrease support for vigilantism? To answer this question, we field simultaneous, in-person experiments in Punjab, Pakistan, and Uttar Pradesh, India, regions where anti-minority vigilantism has been preceded by misinformation. We find that correcting rumors reduces support for vigilantism and increases the desire to hold vigilantes accountable. This effect is not attenuated by prior distrust toward out-groups. By contrast, information about state and elite behavior does not always shape attitudes toward vigilantism. These findings provide evidence that support for vigilantism can be reduced through the dissemination of credible information, even in polarized settings.
