Effort makes us overvalue what we create

Ariely documents what's become known as the IKEA effect: people assign disproportionate value to things they assembled themselves, even flawed or wonky results, compared to identical items made by someone else. In one memorable experiment, participants built origami figures that objectively looked amateurish, then rated them as valuable as professional-grade origami — and were genuinely surprised when outside observers disagreed.

The mechanism isn't really about the object; it's about labor becoming identity. Effort invested in a task gets folded into how we see ourselves, so devaluing the output feels like devaluing the self that made it. This explains why we cling to mediocre projects, past decisions, and even relationships we've poured energy into, independent of their actual merit.

Ariely extends this into the workplace: when employees put effort into something that then gets ignored or discarded without acknowledgment, motivation collapses far faster than the actual cost of the wasted effort would predict. Takeaway: acknowledging effort, even briefly, protects motivation far more cheaply than most managers assume.
