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

Things to try in a market correction: • Respond emotionally, giving in to your lizard brain. It does a good job of keeping you alive, so you might as well hand over management of your portfolio to it. • Rely on your gut instinct to lead you out of trouble. After all, your instincts helped…Read More
Hat tip Josh Brown Today’s chart comes to us from Patrick O’Shaughnessy, author of the forthcoming book, “Millennial Money: How Young Investors Can Build a Fortune.” O’Shaughnessy makes the observation that investing is “almost free” and investor behavior tends to matter more than their actual investments.

In yesterday’s column, I wrote: If you have an issue with Social Security, then fix it. The regressive taxes to fund retirement benefits top out at about $117,000 in 2014. Why not simply raise that to $250,000 next year and $500,000 during the next 20 years. Congratulations, you just made Social Security solvent for the…Read More
