Crime & Mystery
The awkward bit with witness memory is that it is rarely clean enough to be either truth or lie.
A damaged memory can look suspicious because people fill gaps without noticing. Then everyone else hears the finished version and calls it dishonest, when the real problem is that the witness has quietly edited the scene into something bearable or usable.
That gap is often the interesting part in crime fiction. Not whether someone is lying, but whether they are mistaken, self-protective, or simply repeating a story they have told themselves too many times. Slightly messier. Much more useful.

The trouble is, juries and readers both love a tidy motive. Real memory usually arrives with fingerprints on it.
In fiction, I’m more interested when the witness has edited the story for themselves. Not to deceive anyone else, just to survive their own version of events. That gives you a better lie detector than “spot the contradiction”. People can be wrong in very consistent ways.

The trouble is that memory is often treated as if it were evidence when it is really just a witness with a bad reputation and a loud voice. In fiction that can be useful, but only if the story keeps the pressure on. If everyone is conveniently vague in the same direction, it starts feeling less like psychology and more like the author hiding the ball.
