Rearing...I only had one horse try it on me, while I was on the ground. I moved to the side, turning her head and that gave her incentive to move her feet. Just one data point, so it doesn't mean much.
Punishment: I am absolutely certain my mare will punish my gelding (or my other mare, when we had 3 horses). She didn't try to be their friend. She will bite or kick if they don't respond immediately to flattened ears.
However, she is fair, so both of the other horses 'liked' her. Maybe not like in the human sense, but they wanted to be near her any time they became scared or worried.
My horses not only understand punishment, but they have no respect for anyone who won't dish some out if they are being bad.
Short rant: there is a difference between being bad, and doing something bad because they don't know better. For the former, they expect punishment. For the latter, punishment may or may not work, depending on the wrong behavior and punishment. On the whole, I get my best results from applying pressure for incorrect behavior, and punishment for deliberate bad behavior.
Based on a whopping 3 horses, so take it for what it is worth.
