Do you like curly fries? Have you Liked them on Facebook? Watch this talk to find out the surprising things Facebook (and others) can guess about you from your random Likes and Shares.

Social media platforms can use seemingly random online actions to predict deeply personal traits with surprising accuracy. For example, liking a page about curly fries on Facebook was one of the strongest indicators of high intelligence in a research study, not because of the content, but because of hidden social patterns. These predictions rely on analyzing vast amounts of behavioral and preference data from millions of people.
