The Most Common Cognitive Bias
Veritasium

A Veritasium video that runs the 2-4-8 rule-guessing puzzle on people to show how they test only examples that confirm their hypothesis. It uses this to illustrate confirmation bias and falsification.
Recommended as a clear demonstration of confirmation bias and the value of trying to break your own hypothesis.
