You just thought about a red hammer , didn't you?
This is really weird…this is the 98% Red- Hammer test
Doing the arithmetic is a distraction and helps you get into the test mood.
It turns out that the majority of people when asked to choose a color out of the blue, will say "red". It's the same when people are asked to name a tool out of the blue. Most, or a large percentage, will say "hammer."
By putting the two together you get a large proportion of people thinking "red hammer". The test is designed to portray a certain “weirdness” inferring that the test "knows" you were going to say "red hammer".
The purpose of having you do the additions as you scroll down the page is to put you into concentration on something else, so that your answers to the questions actually do come from out of the blue.
