Share, Like, Comment: Sandra Matz PhD Exposes The Truth Behind your Digital Footprint

April 25, 2021

Our guest this week, Sandra Matz PhD exposes the truth behind our online presence. In our conversation, Sandra reveals that with simple analytics, the digital footprints we leave behind online (our Facebook Likes, our credit card transactions, our Google Map searches) add up to paint a very revealing picture of our personality and state of mind.

Sandra Matz PhD is an associate professor at Columbia Business School. She takes a Big Data approach to studying human behaviour. Her methodologies use psychology, computer science and data collection to explore the relationships between people’s psychological characteristics and their digital footprints. 

Sandra’s work has been published in top-tier journals such as Psychological Science and the American Psychologist, and has attracted worldwide media attention from outlets like the Independent, the BBC, CNBC, the Washington Post, the Chicago Tribune, and the World Economic Forum.

Our discussion delves into Sandra’s experience around social media profiles, digital ethics, data privacy and our understanding of informed consent. As always we find out about our guest’s musical taste but this week we even find out what our musical preferences can reveal about our personality and social identities.
