Why do so many adults fall for these questions?

Most of these questions aren’t hard – they’re sneaky. They trigger our fast, intuitive thinking, which serves up an answer in a split second. Psychologist Daniel Kahneman calls it “System 1”. The right answer needs the slow, checking “System 2”.

The most famous example: bat and ball

A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. Almost everyone instantly thinks “10 cents” – but then the bat would cost $1.10 and both together $1.20. The right answer is 5 cents. The question comes from the “Cognitive Reflection Test” and has been given to thousands of students – about half of them got it wrong, even at elite universities.

Order of operations – trap number 1

For 7 + 7 ÷ 7 + 7 × 7 − 7 many people calculate straight from left to right. With multiplication and division first, you get 7 + 1 + 49 − 7 = 50.
