IKEA Effect

Shrink Definition

The IKEA effect is our tendency to value things more when we have put our own effort into making them. The labor of assembling or building something makes us see it as better and worth more than an identical item we didn't touch. Our effort gets baked into our sense of its value. We fall a little in love with what we build.

Plain language

We value things more when we helped make them.

Shrink Insight

Effort isn't just a cost, it becomes part of how we value the outcome.

Why it matters

It explains attachment to our own projects and why we overvalue what we build, in work and at home. It also warns that pride of effort can cloud honest judgment.

Common misunderstanding

People think value comes only from an object's quality. The effort we invest changes how much we think it's worth.

Shrink Perspective

We don't just build things, we build attachment to them.

Shrink Reflection

What am I overvaluing simply because I built it?

Shrink Step

Judge one of your own creations as if a stranger had made it.

Shrink Minute

Recall something you overvalued mostly because you made it yourself.

Shrink Takeaway

Our effort quietly raises our estimate of worth.
