Bare in mind that,  Daniel Kahneman is a psychologist.  The economy prize given to him is because his finding fill up the all the void(especially irrational mistake) of all cheeky economist talk about rationality. IMHO, most "practice economist" has a reason to hate him.

# Need help identifying this cognitive bias or fallacy pointed out by Kahneman in Thinking Fast and Slow

(Asked by: username_0 on 2016-08-19)

This was in Thinking Fast and Slow by Kahneman.

He described a situation where someone might prefer A to B, and B to C, but then might prefer C to A (when A and C are directly compared to each other).

I can't seem to remember the name of this bias or fallacy, and I looked in the book but wasn't able to find the passage.

Anybody remember what it was?

When this event occurs it is known as a failure of "transitivity" of preferences.

Transitive preferences are such that for every X,Y,Z, if X is preferred to Y and Y is preferred to Z then X must be preferred to Z.

Economists define rational preferences as binary relations that are complete and transitive, meaning that we can compare everything and the comparisons are consistent.
