The'pink-haired liberal' has become something of a stereotype, but AI can now predict someone's politics based solely on their looks. A new program can spot tiny nuances in people's facial features that correlate to their political leaning - with over 70 percent accuracy. It was trained on hundreds of photos and voting habits of Americans. The results found that liberals tended to have smaller lower faces, their chins were smaller and their lips and noses pointed downward, while conservatives have larger, wider features in the lower halves of their faces. Dr. Michal Kosinski, the study's lead author, warned that facial recognition tools are dangerous if they fall into the wrong hands because millions of people's information could be accessed without their consent.
