Why conservatives might be better at dieting than liberals

In a series of three studies with more than 300 participants, the authors found that people who identify as conservative perform better on tests of self-control than those who identify as liberal regardless of race, socioeconomic status and gender.

They also report that participants’ performance on the tests was influenced by how much they believed in the idea of free will, which the researchers define as the belief that a person is largely responsible for his or her own outcomes.

For example, conservatives who are more likely to embrace the idea of free will overwhelmingly agreed with statements like “Strength of mind can always overcome the body’s desires” and “People can overcome any obstacles if they truly want to.”
