A Bat and Ball made me Sad

’A bat and a ball cost $110 in total.

The bat costs $100 more than the ball.

How much does the ball cost?

The answer is $5.

Please enter the number 5 in the blank below.


That question is from one of 59 new studies (N = 72,310) which focus primarily on the “bat and ball problem,” found in The formation and revision of intuitions—ScienceDirect by Andrew Meyer and Shane Frederic.

23% of respondents failed to give the correct answer.

I don’t have anything insightful to say but wanted to share because it seems worth knowing.

Additionally, I’m not exactly sure how (and how much) I should update about this.

(Edit: I initially posted the wrong question)
