Regular readers know I enjoy discussing behavioral aspects of investing. The reasons for this are twofold: First, we can’t control the markets, but we can control our own reactions to it (at least we can try). And second, many studies have shown that investors suffer from a behavior gap between what they should garner in returns and what they actually get.
Of all of the failings of human wetware, the one I find most intriguing is cognitive dissonance. You can find technical definitions at Changing Minds, The Skeptics Dictionary or any number of other reference books.
In the context of economics and investing, my preferred definition is as follows: Cognitive dissonance occurs in the mind of an individual when a theoretical belief system is confronted by factual evidence demonstrating outcomes contrary to what theories dictate should occur.
Stated more plainly, when facts conflict with beliefs people find ways to ignore those facts, rationalizing them in a way that allows the disproven ideas to survive. John Kenneth Galbraith famously referenced cognitive dissonance before it was even called that, stating “Faced with the choice between changing one’s mind and proving that there is no need to do so, almost everyone gets busy on the proof.”
I was reminded of this recently courtesy of several seemingly disparate but cognitively-related articles. Continues here
Please use the comments to demonstrate your own ignorance, unfamiliarity with empirical data and lack of respect for scientific knowledge. Be sure to create straw men and argue against things I have neither said nor implied. If you could repeat previously discredited memes or steer the conversation into irrelevant, off topic discussions, it would be appreciated. Lastly, kindly forgo all civility in your discourse . . . you are, after all, anonymous.
