Against Willpower

Here is an excerpt:

These hidden dimensions of willpower call into question the whole scholarly conception of the term, and put us into a lose-lose situation. Either our definition of willpower is narrowed and simplified to the point of uselessness (in both research and casual contexts), or it is allowed to continue as an imprecise term, standing in for an inconsistent hodgepodge of various mental functions. Willpower may simply be a pre-scientific idea—one that was born from social attitudes and philosophical speculation rather than research, and enshrined before rigorous experimental evaluation of it became possible. The term has persisted into modern psychology because it has a strong intuitive hold on our imagination: Seeing willpower as a muscle-like force does seem to match up with some limited examples, such as resisting cravings, and the analogy is reinforced by social expectations stretching back to Victorian moralizing. But these ideas also have a pernicious effect, distracting us from more accurate ways of understanding human psychology and even detracting from our efforts toward meaningful self-control. The best way forward may be to let go of “willpower” altogether.

Doing so would rid us of some considerable moral baggage. Notions of willpower are easily stigmatizing: It becomes OK to dismantle social safety nets if poverty is a problem of financial discipline, or if health is one of personal discipline. An extreme example is the punitive approach of our endless drug war, which dismisses substance use problems as primarily the result of individual choices. Unhealthy moralizing creeps into the most quotidian corners of society, too. When the United States started to get concerned about litter in the 1950s, the American Can Company and other corporations financed a “Keep America Beautiful” campaign to divert attention from the fact that they were manufacturing enormous quantities of cheap, disposable, and profitable packaging, putting the blame instead on individuals for being litterbugs. Willpower-based moral accusations are among the easiest to sling.

Everything Is Crumbling

Here is an excerpt:

The authors called this effect “ego depletion” and said it revealed a fundamental fact about the human mind: We all have a limited supply of willpower, and it decreases with overuse. Eating a radish when you’re surrounded by fresh-baked cookies represents an epic feat of self-denial, and one that really wears you out. Willpower, argued Baumeister and Tice, draws down mental energy—it’s a muscle that can be exercised to exhaustion.

That simple idea—perhaps intuitive for nonscientists, but revolutionary in the field—turned into a research juggernaut. In the years that followed, Baumeister and Tice’s lab, as well as dozens of others, published scores of studies using similar procedures. First, the scientists would deplete subjects’ willpower with a task that requires self-control: don’t eat chocolate chip cookies, watch this sad movie but don’t react at all. Then, a few minutes later, they’d test them with a puzzle, a game, or something else that requires mental effort.

Restricting Temptations: Neural Mechanisms of Precommitment

Summary

Humans can resist temptations by exerting willpower, the effortful inhibition of impulses. But willpower can be disrupted by emotions and depleted over time. Luckily, humans can deploy alternative self-control strategies like precommitment, the voluntary restriction of access to temptations. Here, we examined the neural mechanisms of willpower and precommitment using fMRI. Behaviorally, precommitment facilitated choices for large delayed rewards, relative to willpower, especially in more impulsive individuals. While willpower was associated with activation in dorsolateral prefrontal cortex (DLPFC), posterior parietal cortex (PPC), and inferior frontal gyrus, precommitment engaged lateral frontopolar cortex (LFPC). During precommitment, LFPC showed increased functional connectivity with DLPFC and PPC, especially in more impulsive individuals, and the relationship between impulsivity and LFPC connectivity was mediated by value-related activation in ventromedial PFC. Our findings support a hierarchical model of self-control in which LFPC orchestrates precommitment by controlling action plans in more caudal prefrontal regions as a function of expected value.
