Ash Donaldson — Cognitive dissonance

Multiple-TED attendee and human fac­tors expert, Ash Don­ald­son, wants us to bet­ter under­stand why we believe what we do. In this talk, Ash explains how our minds build belief and then breaks it down, show­ing us how and why humans are fooled into believ­ing that things like Power Bands, anti-aging treat­ments and sup­ple­ments actu­ally work. Along the way, he tells us how as a trainee pilot he man­aged to nearly get him­self killed by allow­ing his beliefs to rule logic and prov­able fact.
