Can you solve this simple puzzle?

A bat and ball cost $1.10.
The bat costs one dollar more than the ball.
How much does the ball cost?

Simple puzzle, right? Well, more than 50% of students at Ivy League colleges got the wrong answer. At other universities the rate of wrong answers was 80%. The lesson of this simple problem is:

many people are overconfident, prone to place too much faith in their intuitions. They apparently find cognitive effort at least mildly unpleasant and avoid it as much as possible.
One of the problems with government is that many of our “leaders” are overconfident, quick to choose a “solution” that they are sure is right for everyone, and are reluctant to do the analytical work to determine whether their answer is even reasonable. Their overconfidence and reliance on intuition inevitably leads to unintended consequences.
