I don’t know how any experiment like this could be taken seriously. Your action could change 15 minutes apart if you feel like having sugar, if the guy felt intimidating or not, if the last thing he said seemed friendly or if his facial expression was off at the very end, etc.

There must be a better way of judging the validity of a social experiment using first principles. There’s a huge psychological side that people completely ignore.
