Probabilistic Thinking - Mental Model

The article says probabilistic thinking helps with decisions, predictions, and expectations because life is full of uncertainty. It uses examples from weather forecasts, project estimates, and confident claims to show that “always” and “never” often hide real uncertainty.

It also argues that people tend to interpret information in ways that fit their beliefs, which makes precise language about probabilities useful. Luck and bad luck matter too, so the point is to think in ranges, examine what could raise or lower the odds, and avoid treating confidence as certainty.
