Ganna explains how data science can help us understand human behaviour. She talks about different types of biases that affect human behaviour (like when we tend to think we are better drivers than we actually are), how data is biased, too, and how building algorithms needs insights from qualitative research. Ganna gives us lots of examples, including from her work on movies and supporting scriptwriters. She shares her thoughts on diversity in tech, positive change, and powerful story telling. As a behavioural data scientist, Ganna combines economics, psychology and computer science. She is co-author of The Big Bad Bias Book and has just written her first children’s book The Smartest Animal of them All.
