God does not play baseball

A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?

The same question was used in a survey on belief in god:

“Some say we believe in God because our intuitions about how and why things happen lead us to see a divine purpose behind ordinary events that don’t have obvious human causes,” study researcher Amitai Shenhav of Harvard University said in a statement. “This led us to ask whether the strength of an individual’s beliefs is influenced by how much they trust their natural intuitions versus stopping to reflect on those first instincts.”

Shenhav and his colleagues investigated that question in a series of studies. In the first, 882 American adults answered online surveys about their belief in God. Next, the participants took a three-question math test with questions such as, “A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?”

The intuitive answer to that question is 10 cents, since most people’s first impulse is to knock $1 off the total. But people who use “reflective” reasoning to question their first impulse are more likely to get the correct answer: 5 cents.

Sure enough, people who went with their intuition on the math test were found to be one-and-a-half times more likely to believe in God than those who got all the answers right. The results held even when taking factors such as education and income into account.
