new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did.

Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →
