How a round works
Choosing before you learn turns every outcome into a surprise you wanted to see. That is the whole trick, and it is how the lessons stick.
A real company’s situation in two or three sentences: the stage it was in, the problem, the decision. No spoilers.
Three or four plausible outcomes. No trick questions: every option is something a smart team might expect.
The real, dated number, its source, two grades and the caveats, then the psychology behind it and what it means at your stage.
The number is graded by its source; the link grades how well we know the psychology explains it.
