I agreed there is no need to invoke TDT/UDT to explain lack of shoplifting.

In addition to what Perplexed said, it seems to me that people tend to care more about their reputation compared to what is evolutionarily adaptive today, probably because in our EEA, you couldn't move to a new city and start over (or if you could move to another tribe, it was only at an extremely high cost), nor did you interact mostly with strangers. That would explain why people are sometimes deterred or motivated by reputation/shame when it doesn't seem to make sense to be, without having to invoke TDT/UDT.
