ive heard polygraphs can be beat with practice and Biden has not nothing if not practice in lying. For 1 million dollars, he should be given a truth serum. I'll even pitch in a extra buck.

I don’t think his mental ability is such that he can beat a poly at this point. Also, even if he passed, would still draw attention to the fact a lot of people think he’ll be swapped out. So if it happens, more people will distrust them.

They're mostly based on how innocent people tend to react, that's why it's unreliable, i.e. you're assuming how people should react.

They first ask you control questions about mundane activities before they ask you the incriminating questions. innocent people tend to get nervous while answering the mundane questions because they don't want to slip up but then they relax more while answering the central questions because they're innocent. Guilty people do the opposite, they're relaxed during the control questions because they're waiting for the tough questions of which they're guilty.

Once you're aware of this it's not rocket science.
