My friend Heath shared this Tim Ferris blog post with me the other day, called Understanding the Dangers of “Ego-Depletion”. Its actually a guest post written by Dan Ariely, who is a professor of psychology and behavioral economics.
Ariely presents the idea that, basically, we can only make good decisions so many times, before we are too mentally exhausted to continue. These “good decisions” are things that require will power, like skipping dessert or working on a less-than-exciting project. Each decision requires a certain amount of effort, and when our lives are such that we are constantly making these often challenging or personally limiting decisions, after awhile our ego just gets depleted, and we fall flat on our face.
“Here’s the reason we make bad decisions: we use our self-control every time we force ourselves to make the good, reasonable decision, and that self-control, like other human capacities, is limited.”
Consider the typical dieter: He might make some rules for himself (or maybe his doctor made them) such as no sugar, no carbs, etc. So for each meal of the day, he has to consciously try and make a good decision about what to eat. Depending on how stressful his day was, he might be running on empty by dinner time and end up making a bad decision. Or, maybe he’s done well for a week but is starting to lose momentum. Consider Ariely’s question:
“From your own experience, are you more likely to finish half a pizza by yourself on a) Friday night after a long work week or b) Sunday evening after a restful weekend? The answer that most people will give, of course, is “a”. And in case you hadn’t noticed, it’s on stressful days that many of us give in to temptation and choose unhealthy options. The connection between exhaustion and the consumption of junk food is not just a figment of your imagination.”
Ariely then gives 6 easy rules to avoid caving under pressure (as well as a pretty realistic mock internal debate about food that I’m sure we’ve all had!) He also sites some interesting studies that demonstrate participants’ wilting ability to focus, remember, and succeed at given tasks as their stress or distraction escalates.
Reading this article made me consider the things I do, and whether or not they are due to ego depletion. I make a number of “bad decisions” on a daily basis (eating junk food, staying up late, procrastinating, etc), but I do these things so often that I have to wonder if they’re due the ego depletion or just a lack of motivation. But then, what’s causing my lack of motivation? Chances are, its ego depletion. My day-to-day life isn’t particularly stressful – in fact, its pretty cushy – but I have underlying stresses that are with me at all times (student loans, getting a job, deciding if I want to move) which definitely put a tinted shade on the rest of my life. Perhaps if I didn’t have those stresses, I would choose to eat salads more often, or get back into a routine of working out every day? Ariely acknowledges that one can’t completely avoid stress and potential ego depletion, but calls upon the common saying “knowing is half the battle”. And I for one am glad to have this new perspective on what might be causing the lack of motivation I’ve settled quite [un]comfortably into for the last few years.
Do you suffer from ego depletion? Have you found ways to overcome it?
