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)
