Not Invented Here Syndrome

A company rejects a competitor's fine idea — not because it is bad, but because it arrived from outside. A cook scorns the other kitchen's recipe. A nation reinvents, at great cost, what its neighbour already perfected. The syndrome: ideas are judged by their birthplace, not their worth.

The psychology is pride disguised as standards. To adopt the outside idea is to admit the outside knew something — and that admission touches status. So the idea is audited to death while homegrown mediocrity passes unexamined. "We have our own way" is the phrase that ends the search.

The cost compounds quietly: every refusal to import is a decision to pay full tuition for lessons others have already learned.

The discipline: evaluate every idea as if its origin were unknown. Cover the label, taste the dish blind. And cultivate the small pride of the great borrowers — the best kitchens, firms, and minds in history have been shameless collectors of other people's good ideas, and honest about the collection.
