I re-posted this link on a message board full of very cautious mothers (they veer into paranoidly cautious, if you ask me). Everyone there who bothered to take the test got a score of 84 or higher.
And most people here who bothered to take the test got mid/low 50s and below.
So there is something to climbers being risk-takers?
It's not only about risk assessment. If you were really smart you would know all the answers definitely and get a perfect score without having to assess any risk.
