Training modes
These cards are built to answer the real pre-session questions: what this mode trains, how long it will take, and whether it fits the kind of thinking work you want right now.
Spot the cognitive error before it costs you.
Learn to name the specific bias operating in any argument, recommendation, or decision. Fluency reduces susceptibility by roughly 30% in follow-up tests.
