The ultimate distraction.

If you've been harbouring suspicions that you're secretly a genius then this simple three question IQ test might give you the answer you've been looking for.
The Cognitive Reflection Test assesses whether you can identify that a simple problem can actually be harder than it first appears. It measures your ability to be methodical and reflective rather than jumping to an obvious conclusion.
The questions are:
1. A bat and a ball cost GBP1.10 in total. The bat costs GBP1.00 more than the ball. How much does the ball cost?
2. If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?
3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
These are the common wrong guesses and correct answers with the logic:
1) Common wrong answer: 10p
Correct answer: 5p
Explanation: "GBP1 more than 5 pence is GBP1.05. GBP1.05 + 5 pence is GBP1.10."
2) Common wrong answer: 100 minutes
Correct answer: 5 minutes
Explanation: "Each machine will always take 5 minutes to make 1 widget. So 5 machines can make 5 widgets in 5 minutes, and 100 machines can make a 100 widgets in 5 minutes."
3) Common wrong answer: 24 days
Correct answer: 47 days
Explanation: "As the patch doubles in size every day, if you go back one day then it will halve in size. So if on the 48th day the patch covers the whole lake, on the 47th day it would have been half this size, so would have covered half the lake."
Of the near 3,500 people surveyed, 33 percent answered all questions wrong and 83 percent got at least one wrong. Only 48 percent of MIT students sampled were able to answer all three correctly.
We're guessing a certain somebody headed for the White House wouldn't have have fared too well on this test, either.
