Spot the Biases That Cloud Your Judgment

Across 51 experiments with more than 18,000 people, the same study was rated better when its conclusion suited the reader's politics, on the left and the right alike. From the inside, it feels like clear thinking.

On the beliefs that matter to you, the conclusion often arrives first and the reasons follow. Being clever does not protect you, and knowing the names of biases does little on its own. What helps is a habit you use at the moment you decide.

This course gives you that habit: the question that shows your standard has moved, five tests that each remove one motive (your preference, a bending rule, your stake, your group, what you have already spent), and a clear account of which bias findings still hold up and which did not. You run all five on a real belief and use them on a live decision.

Who it's for

Founders and operators: who want to pressure-test the decision they already like before they commit money to it.

Analysts and researchers: who need a repeatable way to catch their own motivated reasoning before someone else does.

Anyone who argues for a living: who wants to tell weighing the evidence apart from defending a position.
