I think it would be surprising if indeed it’s not possible to make an accurate polygraph. I would think it should even be quite doable to train a neural net on video of a person talking and it should be able to predict if he’s lying.
I don’t know if anyone has done this (CIA or anyone else) but it seems quite doable as long as you have the training data which the feds plausibly have
After thinking about this for a bit:
