Why Experts Make Better Decisions (and Why It Doesn’t Transfer)

Expertise is not general. It is built in specific environments.

Smart people still make poor decisions outside their domain because they lack calibrated intuition about what matters.

Did you know?

Expert advantage is strongest in domains with stable rules and consistent feedback, and weakest in unpredictable environments.
