Show description

We created this video in partnership with Unlikely Collaborators. Psychologist Lisa Feldman Barrett argues that reality is built, not found, and that changes everything about how we interact with each other.

Psychologist Lisa Feldman Barrett makes the case that it's not quite that simple. Barrett, a University Distinguished Professor of Psychology at Northeastern University, argues for a third option: relational realism, where reality is built in real time from sensory signals and the remembered past your brain uses to interpret them. Together, those ingredients create your Perception Box, the lens through which every moment reaches you. That means reality exists in relation to you — and in relation to whoever else is experiencing it alongside you. Barrett unpacks what it means for two people to experience the same moment differently, why "objective reality" doesn't hold up in an argument, and why she considers curiosity the key to expanding the reality you have access to.
