Kavanaugh became a national figure in 2011 when he cast dissenting vote in Obamacare appeals court case. He was talked up as a Supreme Court nominee from early 2012.

Sensors for measuring electrical signals from skin (EEG, ECG, GSR, EMG) have been pretty static for decades, other than miniaturization. Even the basic analysis techniques haven’t changed much. So I don’t think this is unique to lie detection.

The idea behind polygraphs: establish a baseline and look for deviations due to stress; measuring stress from sweat (GSR), HR and BR, sounds reasonable from first principles. Intersubject variability is probably the biggest obstacle.

Did you look at the article I cited? There is no theoretical construct uniquely linking lying to ANS activation, or differentiating lies from other anxiety sources, and there is no known way to do an adversarial probe. (I can do a Tweet-thread on the evidence if you'd like.)

I'll have to read it later. I did see in one of the abstracts you cited that while they knocked down exaggerated effect size claims, there still remained small to moderate effect sizes, which would be consistent with moderate accuracy. But I am curious and want to read more.

Long ago I read Elizabeth Loftus's books on false and recovered memories. Back then, I naively thought society would reject stuff like this. I didn't grasp the incentives.

Her lawyer, Katz, likely uses polygraph tests the way many PI lawyers use "soft tissue damage."
