Some of the criticisms are valid, and the results to not reflect well on us as people. The 33% of people who can keep to their stated ethics in the face of authority probably have a really hard time believing that 66% of people cannot. To them it seems easy and obvious that you just don’t violate your ethics. But imagine it this way: for hundreds of thousands of years humans lived in tiny tribes wandering in the wilderness. Failure to heed the orders of the tribe’s leaders would have been a virtual death sentence for most of that time. That environment literally breeds for people who obey even when they think it’s a bad idea. That’s apparently not long enough for the trait to have become universal, thankfully.
I don’t know about the TPSE though. I didn’t cite it either.
