Summary

How much can you really tell about someone at first glance? Nicholas Rule, PhD, of the University of Toronto, talks about the science of first impressions: How your brain starts making judgments about other people in milliseconds--before you’re even aware of it--how accurate those judgments are and how they’re shaped by stereotypes and biases; the research on “gaydar”; to what degree you can pick up on traits like extraversion and trustworthiness; and the real-world consequences of our accurate – and inaccurate – snap judgments.
