Thanks for the reference to Dan Ariely's 2015 documentary. I started my study of human lying in 2018. I see what Dan did in the trailer and I am certain this documentary is worth watching.
Looks like he is an excellent observer.
Coercively controlled relationships are all to common. It's always a sure sign of sociopathy which
is often stimulated by youthful success in lying. The one piece of advice I promote to NEVER VOTE FOR A DIVISIVE LIAR is actually extendable: NEVER ASSOCIATE WITH A PERNICIOUS DIVISIVE LIAR. You will be sorry. It's a tell of bad times to come if you let them have any control at all over your life.
This is a bit more detail on that I wrote about on Trump:
The whole thing on the Internet Court of Lies is to give people a chance to easily see what other actually think about suspected lies, or believed truths. People cannot learn about such things without dialogue with other people. We know that by the science. Our brains just work (compute) that way.
