When someone gives you three contradictory reasons, none of them is the real one.
Kettle logic is a term from Sigmund Freud, describing a set of mutually inconsistent excuses.
Freud's example: I never borrowed the kettle, it was already broken, and I returned it undamaged. Three defences that cannot all be true. When you hear that pattern, the stated reasons are not the reason.
The original is a joke Freud used to illustrate how the mind defends itself: each excuse is individually plausible and together they undermine each other, which reveals that the person is reaching for defences rather than reasons.
In objections. *It is too expensive, and we do it in-house anyway, and now is not the right time.* Three reasons that pull in different directions. If price were really it, the in-house point would be irrelevant.
In performance conversations. *I didn't get the brief, and I was too busy, and it wasn't really my job.*
The pattern is the signal. One clear reason is usually the truth. Three that contradict each other means the real objection has not been said.
Do not argue with any of them — you will win and lose. Ask instead: *if we solved all three of those, would you go ahead?* The answer tells you whether you have heard the actual objection.
