An iterated game will tune emotional responses to achieve the same end. Draper has no doubt had many chances in his life to provide negative but true and positive but false comments on his investments. If society punishes negative but true comments he's damn well going to notice and make fewer of them. If society further fails to punish positive but false comments about his investments, he's not going to invest the mental resources that would be required to avoid them. A little experience substitutes for a lot of strategy.
