Scott Alexander explores how controversial ideas spread more effectively than uncontroversial ones, using examples from activism and media to illustrate this 'toxoplasma of rage' effect. Longer summary

This post discusses the concept of 'toxoplasma of rage', where controversial and outrage-inducing ideas spread more effectively than uncontroversial ones. Scott uses examples like PETA's provocative campaigns, viral rape cases, and the Ferguson protests to illustrate how activists and media are incentivized to focus on the most divisive cases, even if it ultimately harms their cause. He compares this to the toxoplasma parasite's life cycle and explores how social media platforms like Tumblr can amplify these effects. The post concludes by suggesting that this phenomenon is part of a larger system of perverse incentives that makes it difficult for society to focus on important but uncontroversial issues.
