A lot of emphasis is put on IQ tests to work out the intelligence.

But in truth, researchers are always trying to create new ways with which to magnitude how crafty we are.

A few years ago, clergyman Shane Frederick devised a brief 3 doubt consult to magnitude a person’s cognitive ability.

While not a approach magnitude of IQ, the Cognitive Reflection test is designed to magnitude a person’s bent to overrule their tummy response to work out what an answer should be.

On the face of it the 3 questions are elementary but all is not as it seems.

Proof of its problem can be seen in the fact that only a tiny suit of students from the strange participating universities scored top marks.

In fact, 20% of students from Harvard who took the test scored zero.

See how you get on (try not to demeanour at the answers underneath)

The test

1. A bat and a round cost £1.10 in total. The bat costs £1.00 some-more than the ball. How much does the round cost?

2. If it takes 5 machines 5 mins to make 5 widgets, how prolonged 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 whole lake, how prolonged would it take for the patch to cover half of the lake?

The answers

Question 1

The tummy greeting is to answer 10p. But if you consider about it that would meant the bat is only 90p some-more than the ball.

In sequence for there to be a £1 difference, the round would need to cost 5p and bat £1.05.

Question 2

A appurtenance can make a widget in 5 minutes.

That means two machines would furnish two widgets in 5 minutes.

If you had 100 machines producing widgets then it would take 5 mins to have 100 widgets.

Question 3

If the lily patch doubles in distance every time then the day before the full lake is covered only half of it would be covered.

Since it takes 48 days for the lake to be covered it would only take 47 for half of it to be covered.
