Scott Alexander explores the effectiveness of public awareness campaigns, presenting examples of both failures and successes. He analyzes various theories about why some campaigns work while others don't, but ultimately concludes that it's difficult to predict the success of future campaigns. The post discusses failures like DARE, Scared Straight, and diversity training, as well as successes like anti-smoking campaigns and seatbelt promotion. Scott suggests that campaigns inflicted on captive audiences may be more likely to be counterproductive, but acknowledges that this theory doesn't fully explain all outcomes. He ends by expressing skepticism about public awareness campaigns, partly due to the implications for society if they were consistently effective. Shorter summary
