Since the advent of the deadline, procrastinators have suffered society’s barbs for putting off until later what needs doing now. But it turns out that many people appear to be finishing things sooner than they need to get them done. They are “precrastinators,” researchers say.

“There is an overwhelming tendency to precrastinate,” according to a paper published in May in the journal Psychological Science. The behavior might include answering trivial emails, for example, or paying bills far ahead of time. “It’s an irrational choice,” the paper said, but it also reflects the significant trade-offs people make to keep from feeling overwhelmed.

The paper described an experiment at Pennsylvania State University that was meant to explore decision-making when it comes to physical effort. Students were asked to carry a beach bucket down an alley. They were given a choice: They could pick up a bucket near the start of the alley and carry it to the end, or they could pick up a different bucket that was closer to the end of the alley, walk a few steps and put it down.

The researchers assumed that most of the subjects would choose the bucket that required the least amount of lifting time. Instead, most picked up the bucket that was closer to them, a decision that forced them to carry it longer than necessary. In other words, they gave themselves extra work for no apparent benefit.
