A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that the trustworthiness of our intuition is really influenced by what is happening physically in our bodies. "We often talk about intuition coming from the body—following our gut instincts and trusting our hearts", says Barnaby D. Dunn, of the Medical Research Council Cognition and Brain Sciences Unit in Cambridge, U.K., first author of the new paper. What isn’t certain is whether we should follow, or be suspicious of, what our bodies are telling us. And do we differ in the influence that our gut feelings have on how we make decisions?
