Camera spots your hidden prejudices from your body language

ARE your hidden biases soon to be revealed? A computer program can unmask them by scrutinising people's body language for signs of prejudice. Algorithms can already accurately read people's emotions from their facial expressions or speech patterns. So a team of researchers in Italy wondered if they could be used to uncover people's hidden racial biases. First, they asked 32 white college students to fill out two questionnaires. One was designed to suss out their explicit biases, while the second, an Implicit Association Test, aimed to uncover their subconscious racial biases.
