as social animals, we manipulate each other constantly. all it takes is a word, a grunt, a glance, a micro-aggression, even an unwitnessed action. are you suggesting we regulate all human behavior?
I'm sure you understand that there's a difference between normal, personal human interactions, as you've just described, and a complex technological system designed and implemented for use in a business setting?
yes, but the original question made a broad statement about regulating human manipulation. my rebuttal was to ask where we draw the line.
note that historically we've allowed all kinds of manipulations (like basically lying in advertisements, caveat emptor), in an abundance of caution to avoid infringing our 1st amendment rights (in the US).
