The psychology of human misjudgmentPart II

Doubt-avoidance tendency

The brain rushes to resolve uncertainty by reaching a conclusion fast.

Doubt-avoidance tendency illustration

Humans hate sitting with unresolved questions. Given uncertainty, we'll generally reach for any plausible answer rather than tolerate the discomfort of not knowing. Salesmen, demagogues, and confidence-men exploit this hourly.

The bias is what makes "strong opinions, weakly held" so hard to actually practise. Most strong opinions get held strongly because they're our way out of doubt. Updating them means re-entering the discomfort.

For operators: notice when you're rushing to a conclusion. If you've decided in under five minutes on a question that genuinely deserves five hours, you're probably resolving the doubt rather than answering the question.

Examples in the wild

Operating

Most bad hiring decisions are made in the first five minutes of an interview, then justified for the next hour. The brain resolved its doubt early.

Investing

Pundits get on TV by sounding certain, not by being accurate. Audiences reward the resolution of doubt over the calibrated uncertainty that's actually informative.

Everyday life

Quick answers to hard personal questions ('should I take this job?') usually aren't answers, they're escapes from sitting with the question.

Doubt-avoidance tendency is one of the mental models we apply through real cases inside the Pareto MBA — a part-time program for professionals who want to think clearly about business.
