The psychological barrier to learning is your own belief system

Alex Edmans: What to trust in a "post-truth" world · 17:51 · Video: TED · Watch at the source

In short: In an era of rampant misinformation, our biggest obstacle to truth isn't a lack of data, but our own biology. This talk explores how to bypass confirmation bias to find evidence you can actually trust.

Researcher Alex Edmans examines how confirmation bias—the innate tendency to favor information that aligns with our existing views—distorts our perception of reality across social media and politics. He argues that true learning is only possible if you are genuinely open to the possibility of being wrong.
