In movies it is shown that through polygraph test it can be found whether a person is lying or not. But we all know that it is not correct. What I am asking can the polygraph test be modified, more data collected so that it becomes more accurate ? Also is there any alternative to polygraph machine to find whether a person is lying ?

The sticking point would be actively trying to remember something would look like lying.

Like, ask someone their name and they'll answer immediately just yanking straight from memory.

Ask them where they were on Dec 2nd 2017, and them trying to remember is going to look like them trying to come up with a story.

The issue is when we don't know an answer, it's normal to just make shit up but be confident it's the truth.

We learned a lot about that from split brain patients, but since we're not cutting brains in half anymore, we can't really study it. Just review the old case folders from the brief window it was a thing and those patients didn't understand what was happening

Same thing with dementia patients.
