Culture add over culture fit
'Culture fit' started as a useful idea and ended as a license to hire people who remind us of ourselves.
In debriefs, "not a culture fit" is the irrefutable argument - vague enough to mean anything, strong enough to end the discussion. Sometimes it names something real: pace, candor, risk appetite. Often it names only difference. The upgrade is a more precise question.
Fit the values, add to the mix
Split the concept. Culture fit should cover only non-negotiable behaviors: how the institution treats clients, handles bad news, resolves disputes. Those are legitimately screened. Everything else - background, style, communication pattern, alma mater, humor - is where you want addition, not similarity. Teams that all fit each other make comfortable, correlated mistakes.
Making it operational
- Write down the three to five actual behavioral values, with examples
- Score fit only against those, with evidence
- Add one question to every debrief: "What would this person add that the team lacks?"
The test of the test
When "fit" is raised, ask: which value, and what was the evidence? If the answer cannot be produced, the flag is taste, not risk. Organizations that enforce this discipline hire a wider range of people - and then discover, repeatedly, that the unconventional hire outperforms.
