Mastercard…because MAOA is priceless….
Introduction (via Valerie Ross SciAm)
When trying to understand why some people have trouble living within their means, we tend to blame factors such as high interest rates and irresponsible spending. Now researchers have found another possible culprit to add to the list: a gene linked to credit-card debt.
Earlier work has shown that genetics plays a role in how we handle money. But a recent study was the first to show that a particular gene affects financial behavior outside the lab. Researchers at the University of California, San Diego, and the London School of Economics looked at genetic data and questionnaires already collected from more than 2,000 young adults aged 18 to 26 as part of the National Longitudinal Study of Adolescent Health. In particular, they looked at whether these young adults said they had any credit-card debt and what version of the MAOA gene they had.
Monoamine oxidase A (MAOA) is an enzyme that breaks down neurotransmitters (signaling chemicals) in the brain. Previous studies have linked the low-efficiency versions of the MAOA gene—the variants that cause less MAOA to be produced by brain cells—to impulsiveness.
