Pretty Sure

How well do you know what you don't know?

You'll get 5 estimation questions. For each, give a range you're 90% sure contains the true answer.

• Too narrow and you'll miss. That makes you a Bold Guesser.
• Too wide and you'll score almost nothing.
• No idea? Stretch the range wide and lock it in. That's the honest answer, even though it scores little.
• Perfectly calibrated means the truth lands inside your range 9 times out of 10.
