How We Overvalue the Things We Create

Behavioral Psychology
Ariely's "IKEA effect": Not only do we like things that we make more than similar things made by others—but we think other people should value them more as well.

Question: Why do we attach more value to things we create ourselves?

Dan Ariely: I don’t know if you’ve had the experience of going to IKEA, but I go from time to time and the last thing I did was I built a toy chest for my kids.  And when I got home with this box, actually a set of boxes, and I start assembling them, for me, the instructions were very unclear, and I kept unscrewing things and screwing them wrongly and had to disassemble and put it back together and so on.  By the end of the day, I worked a lot, it was not a particularly beautiful piece of furniture, but I was actually quite attached to it.  And I think that’s kind of the interesting idea, is that when you put a lot of yourself into it, some sweat and energy and anger and maybe even frustration, you end up loving the end product a bit more.

So we tried to do this experiments and we got people to build Legos and origamis and all kinds of things.  And the first thing we found was if there was an origami that you built and an origami that somebody else built, you think that yours is much, much more beautiful.  Not only is it more beautiful, you’re willing to pay much more for it, right?  Now the question is why?  You can imagine, I built an origami that is uniquely good for me and you, the other origami is not, so it’s unique to me, it’s not about the fact that I kind of wrongly value it, it’s just that it has some features that I particularly like.

So we asked people to predict how other people would pay for it and turns out people are really wrong with it.  Not only do we like more the origami we make, we think other people would love them as well.  And you can think about kids like this, right?  I have two wonderful kids, I love them dearly, I think they’re amazing.  When we go to a party and they dance or do something, I can’t believe that any of their parents would want to do anything but look in my kids, right?  And that’s the issue, right?  They are my kids, I think they are wonderful, but, not only that, I think that other people should see them as wonderful as I see them.  And the same thing happened with origami or with everything we make, not only do we overvalue it, we think that everybody will share our perspective.

And this, of course, creates both opportunities for better things and opportunities for mistakes, right?  So if you’re a company and you can create things that people would actually put something of themselves into it and actually value it more, that’s a great thing to do, right?  There’s lot of opportunities for tailoring and custom made and user designed on the Web.  It’s also about cooking for yourself and doing your own garden and fixing things yourself because we might not understand it if we do something of ourselves we would like it more, but the fact is, we likely would do the same thing.  But of course, there’s the down side and the down side is if we create something, we end up loving it, perhaps too much, and we don’t see it in an objective way and as a consequence, we can make mistakes as well.  And that’s actually a general comment about rationality and irrationality.  Rationality... irrationality is not always bad, it’s not always that a rational person is better than irrational, it’s a mixture, right?  It’s really wonderful that we can love our kids so much, that's why they actually get to live and we care about them.  But at the same time, our blindness to them or to the weaknesses can actually create some negative consequences as well.
