Does anchoring on deadlines cause procrastination?

The phe­nomenon of an­chor­ing seems to pre­dict that dead­lines will cause you to start a pro­ject near the dead­line.

In more de­tail:

Any num­ber you con­sider as an an­swer to a ques­tion will be­come an an­chor and draw your an­swer to­wards it. Since you con­sider a dead­line as a time to finish a pro­ject, your de­ci­sion about when you should ac­tu­ally finish the pro­ject will be drawn to­wards it.

That’ll make you start the pro­ject later, even though you know con­sciously that plan­ning to finish a pro­ject near the dead­line is a bad idea.

It’s analo­gous to an ex­am­ple from Kah­ne­man’s Think­ing, Fast and Slow—peo­ple buy more cans when there’s a sign tel­ling them that they can only buy 10.

So, what I’m pre­dict­ing is that any­thing that pre­vents an­chor­ing will re­duce pro­cras­ti­na­tion when there’s a dead­line. Con­sciously de­cid­ing when you plan to finish by ad­just­ing from a much ear­lier time, maybe?

EDIT: Bren­don_Wong points out that “pro­cras­ti­na­tion” re­ally refers to putting things off, which has an emo­tional cause. I think he’s right. What I’m talk­ing about isn’t re­ally a pro­cras­ti­na­tion, then, but bad plan­ning.
