Putting Genetic Studies into Perspective

The genetics field has grown dramatically in recent years as we look to our DNA to explain our health and predict future diseases and disorders. At-home genetic testing kits are readily available and relatively affordable these days, though the tests may not live up to the hype and raise some ethical questions.

Beyond pursuing answers about our health, researchers, funders, and the public have grown increasingly interested in behavioral genetics, as we seek insight into cognition, intelligence, and personality. But don’t be too quick to buy into simple causal explanations about why you may have certain traits. For example, scientists argued in a New York Magazine article last year that Catechol-O-methyl transference may cause certain people to handle stress better than others.
