From only 300 Facebook likes, an algorithm can model your personality more accurately than your spouse can. Kosinski & Stillwell, PNAS 2015
The behavioral inference model behind every feed, can identify your anxieties, your impulses, and your politics. It knows when you feel stressed or anxious1 Facebook told advertisers it can identify teens feeling “insecure” and “worthless” , if your parents separated before you turned 12, whether you're pregnant or not2 How Target figured out a teen was pregnant before her father did , and even the insecurities you didn't know you had.
It knows you better than you know yourself.
It is the most precise system ever created for understanding a human being, and it's being used to optimize ads.
We're taking that same data, and giving it back to you.
