How come there's no ethical review for research that interacts with people? (I mean it's there in medicine and psychology, and probably for many economics experiments too.)
I can’t imagine it will stay that way forever. As more and more critical tools and infrastructure go digital, allowing people to just whack away at them or introduce malicious/bad code in the name of research is just going to be way too big of a liability.
edit: oh, it seems they got an exemption, because it's software research - https://news.ycombinator.com/item?id=26890084 :|
