Two Experts Disagree

I like dissent (assuming there are good arguments made on both sides) because it helps in the way I think about things. What I don’t like is dissent with no reasonable argument or logic behind it. “I disagree because I have a gut feeling about it” isn’t good enough. Describe that feeling and tell me why. I may change my viewpoint. Even someone who tends to be skeptical about a lot of things, I can easily be swayed by the voices I already have a bias toward. That’s why I found an article over the Thanksgiving break rather interesting.

The article titled “Willpower, It’s in Your Head” was co-written by Carol Dweck. She wrote this article disagreeing with social psychologist Roy F. Baumeister and the New York Times science writer John Tierney who conclude in their book, Willpower: Rediscovering the Greatest Human Strength, that willpower is biologically limited and relies on a replenishment of glucose. Dweck argues that you can develop willpower. Hmmm…I like both Dweck and Tierney’s writing, so who is correct? Both cite the marshmallow test in their research.

Perhaps both are right and that even though we may have genetic predispositions, there are many things we can become better at, including willpower. One neurologist I heard a few years ago said sometimes we have to develop new neural pathways. Old habits, impulses, and temptations will remain, but those new pathways will make it easier for us to resist those impulses. For now, here’s what I think: It is biology, but we have the capacity to change it.
