In the wake of sweeping protests about racism and police brutality, this week we speak to Dr Pragya Agarwal to unravel the way our implicit or 'unintentional' biases affect the way we communicate and perceive the world. Dr Agarwal spoke to author and BBC broadcaster Kavita Puri about her new book 'Sway' and to answer questions like: is prejudice rooted in our evolutionary past? How has bias affected technology? And how can understanding bias help us root our racism and discrimination in our societies? To find out more about Dr Agarwal's book click here: https://amzn.to/2V0pTmz.
