Michal Kosinski, a Stanford-affiliated researcher, claims to build an algorithm to expose people’s political views from social media profiles and facial expressions. He used a dataset of over 1 million Facebook and dating sites profiles. He trained an algorithm that, according to him, can correctly classify political orientation in 72% of “liberal-conservative” face pairs.
His work revolves around the idea that a person’s personality can be judged from their appearance. According to Kosinski, several facial features such as head orientation, age, gender, emotional expression, and ethnicity reveal political affiliation.
