Why would one want to halt a helping factor in which people could pick a lesson or two? Anxiety often forces people to learn things in order to prevent greater downfall, though at some point most people just give it up. However since investments involve money, it would somehow make the investor think of what other things could they do whilst the price is in a crash. It forces us to think rational and think smart. There's really not much we can do to alleviate that anxiety of theirs TBH, and why should we?
