On Coffee and Creativity

I’ve been drinking one to two cups of coffee in the mornings over the last few months. But as Maria Konnikova explains, I shouldn’t expect the caffeine to boost my creativity:

When we drink a caffeinated beverage, the caffeine quickly crosses the blood-brain barrier—an interface of sorts between the brain and the body’s circulatory system, designed to protect the central nervous system from chemicals in the blood that might harm it—and proceeds to block the activity of a substance called adenosine. Normally, a central function of adenosine is to inhibit the release of various chemicals into the brain, lowering energy levels and promoting sleep, among other regulatory bodily functions. When it’s blocked, we’re less likely to fall asleep on our desks or feel our focus drifting. According to a recent review of some hundred studies, caffeine has a number of distinct benefits. Chief among them are that it boosts energy and decreases fatigue; enhances physical, cognitive, and motor performance; and aids short-term memory, problem solving, decision making, and concentration.

But all of that comes at a cost. Science is only beginning to unravel the full complexity behind different forms of creative accomplishment; creativity is notoriously difficult to study in a laboratory setting, and the choice of one approach over another limits the way that creativity can be measured. Still, we do know that much of what we associate with creativity—whether writing a sonnet or a mathematical proof—has to do with the ability to link ideas, entities, and concepts in novel ways. This ability depends in part on the very thing that caffeine seeks to prevent: a wandering, unfocussed mind.

Bummer!
