Ask the panel

Independent guesses, averaged, cancel each other’s errors. Guesses that follow the first voice do not.

5 minutes · trains Read hidden information · points only, never money

Guess how many dots are in a box, alongside a panel of bots. Sometimes everyone guesses alone; sometimes everyone hears one bot's guess first. Then see how far off the panel's average was each way.

Each round shows a box of dots. You and a panel of 8 bots each guess how many there are. Each bot is wrong by its own amount, some too high, some too low.

In some rounds everyone guesses alone. In others, bot A speaks first and everyone hears its guess before making their own. Six boxes; after each, see your guess, the panel's average and the true count.

Guess by eye: counting every dot is not the point. If you cannot see the picture, any number will do; the lesson is in the panel's averages.

  • Estimate alone, then pool Have everyone estimate alone before anyone speaks. Averaged, independent guesses cancel each other’s errors; guesses that follow the first voice do not.
  • Start from the base rate Before judging one case, ask how often cases like it turn out each way. Start from that, then adjust for what this case shows.
  • The Read hidden information course Lessons and practice for the skill this lab trains.
