IL41: They’re Not Just Reading You... They’re Rewriting You ft. Sandra Matz

Top Traders Unplugged

What if knowing you isn’t the end goal... but shaping you is? In this episode, Kevin Coldiron speaks with Columbia professor Sandra Matz about how algorithms trained on our clicks, searches, and faces don’t just predict our behavior - they influence it. They unpack how personalization narrows possibility, why convenience can come at the cost of resilience, and what happens when machines learn to mirror us better than we mirror each other. From the false promise of data consent to the quiet collapse of complexity, this is a conversation about power, psychology, and the systems quietly remaking the human experience.
