In the study, which was published in the journal Personality and Social Psychology Bulletin, psychologists measured the volunteers' desires to increase their self-control by having them rate their level of agreement to statements like, "I want to be able to better resist temptations." The subjects were also asked to rate their current level of self-control. Then, they began working on either an easy or a difficult assignment. According to Science Of Us, those who did the best on the challenging assignment were the least likely to say they'd like to be better disciplined, and those who did the worst were the most likely to wish for more self-control.

But hold on — doesn't it make sense that those who aced the difficult task did so precisely because they already had self-control, and therefore didn't wish for it? Well, in another experiment, the researchers controlled for this possibility by actually manipulating people's desire for self-control. They asked volunteers to write an essay explaining either that why self-control was a good thing, or how it could cause problems—then had them complete either an easy or a hard task. Again, those people who were made to want self-discipline did worse on the difficult task than those who were prompted to think about how self-control causes problems. Interestingly, in both experiments, a desire for self-control had no effect on the participants' performance on the easy tasks, suggesting that it's only on the really challenging stuff where a wish for discipline comes into play.

But, why? Essentially, you psyche yourself out: thinking about things you wish you had highlights the fact that you don't have them. To fight this effect, the researchers suggest a few things. If you find yourself wishing for discipline, try your best to connect that wish to a specific action you can take: for instance, instead of wishing you had the self-control to avoid online shopping, take concrete steps to actually avoid it by leaving your credit card at home or forbidding yourself from visiting shopping websites during certain hours of the day. The researchers also suggest reframing the idea of self-control: instead of thinking of it as a trait you have or you don't, think of it as an unlimited resource you can tap at any time.
