In emphasizing human cognitive limitations, as behavioral finance rightly does, we therefore need also to remember the interactions between those limitations and the mechanisms, both "social" and "technological," that constitute markets. The interactions by no means always eliminate the effects of the limitations the crises of 1987 and 1998 can be seen as cases in which they exacerbated them but I suspect they are always important.
