Statistical base rates predict outcomes better than compelling individual stories. Your brain will fight this truth every time a vivid narrative competes with a dry statistic — and your brain will be wrong.
For one week, keep a Base Rate Log. Each time you encounter a vivid anecdote — a news story, a personal account, a social media post, a colleague's experience — that makes you feel like something is common, dangerous, or likely, stop. Write down your gut estimate of the probability. Then look up.
The most common failure mode is not ignorance of base rates — it is knowing the base rate and overriding it anyway because the narrative feels more real. You hear the statistic that airline travel is safer than driving. You understand it intellectually. Then you watch news footage of a plane crash.

Pick one belief you currently hold with high confidence — about your work, your skills, your team, or your market. Write it as a clear statement. Now spend 15 minutes searching exclusively for evidence that would prove it wrong. Talk to someone who disagrees with you, read the strongest critique,.
Performing a half-hearted search for disconfirming evidence, finding nothing convincing, and using that failure as additional confirmation. This is the most common way people co-opt this practice: 'I looked for reasons I was wrong and couldn't find any — so I must be even more right.' The test is.
