Y11W21WR Why we overvalue what we've built ourselves

Observational
The writing prompt

Notice your own IKEA effect in action on a current project, and describe specifically how your valuation of the work differs from what an outside evaluator would say.

1Retrieval check

Q1.What is the IKEA effect (Norton, Mochon and Ariely)?

  • AFurniture that breaks easily
  • BPeople value things they’ve partly built themselves significantly more than identical objects they didn’t build
  • CA preference for flat-pack over pre-assembled
  • DAn effect that only appears with physical objects

Q2.When is the IKEA effect smaller, per the article’s counter-thread?

  • AWhen more people are involved
  • BWhen the building goes badly or when competitors’ products are obviously better
  • CWhen the cost is low
  • DNever — the effect is uniform
Show answer key

Q1 → B. People value things they’ve partly built themselves significantly more than identical objects they didn’t build.The effect extends to folded origami, cooked meals, investment strategies you’ve chosen, and ideas you’ve generated.

Q2 → B. When the building goes badly or when competitors’ products are obviously better.The effect depends on effort producing a result you can credit yourself with — when the build fails, the effect weakens.

6Exemplar paragraph (not about this article)

(1) My current project is a study system I built last term: colour-coded notes, a weekly review template, a custom flashcard deck. (2) I value it because every component reflects a decision I made — the blue for definitions, the specific review cadence, the card format. (3) An outsider, asked to evaluate it against Anki or a commercial template, would probably say the results are indistinguishable and the overhead is higher. (4) The gap is almost entirely IKEA effect: I value the authorship, not the output. (5) The article’s caveat fits too — when the system fails (a topic I get wrong), my attachment weakens slightly, suggesting my valuation is propped up by the building, not the performance.
