Do you see how this image is changing?
Change blindness is the failure to detect non-trivial changes in the visual field. The failure to see things changing right before your eyes may seem like a design fault, but it is actually a sign of evolutionary efficiency.

The term ‘change blindness’ was introduced by Ronald Rensink in 1997, although research in this area had been going on for many years. Experiments have shown that dramatic changes in the visual field often go unnoticed whether they are brought in gradually, flickered in and out, or abruptly brought in and out at various time intervals. The implication seems to be that the brain requires few details for our visual representations; the brain doesn’t store dozens of details to which it can compare changes (Simons and Levin: 1998). The brain is not a video recorder and it is not constantly processing all the sense data available to it but is inattentive to much of that data, at least on a conscious level.
Change detection in films is notoriously poor when the change occurs during a cut or pan, as demonstrated by the color-changing card trick video and a number of other videos where a different actor appears after a cut, without the change being noticed by most viewers. Some experiments have shown that a person may be talking to someone (behind a counter, for example) who leaves (bends down behind the counter or exits the room) and is replaced by a different person, without the change being noticed.
Apparently, change blindness is due to the efficient nature of our evolved visual processing system, but it also opens the door to being deceived, much to the delight of magicians and sleight-of-hand con artists.

Recency bias is the tendency to think that trends and patterns we observe in the recent past will continue in the future. Predicting the future in the short term, even for highly changeable events like the weather or the stock market, according to events in the recent past, works fine much of the time. Predicting the future in the long term according to what has recently occurred has been shown to be no more accurate than flipping a coin in many fields, including meteorology, economics, investments, technology assessment, demography, futurology, and organizational planning (Sherden, The Future Sellers).
Doesn’t it strike you as odd that with all the intelligence supposedly going on that such things as the breakup of the Soviet Union, the crumbling of the Berlin wall, the former head of Sinn Fein meeting with the Queen of England, the worldwide economic collapse of recent years, the so called “Arab spring,” the recent attacks on U.S. embassies in several Muslim countries, and a host of other significant historical events were not predicted by the experts? Wait, you say. So-and-so predicted this or that. Was it a lucky guess or was the prediction based on knowledge and skill? If the latter, we’d expect not just one correct prediction out of thousands, but a better track record than, say, flipping a coin. Find one expert who’s consistently right about anything and we still have a problem. How can we be sure that this sharpshooter isn’t just lucky. If thousands of people are making predictions, chance alone tells us that a few will make a right call now and then. The odds in favor of prediction success diminish the more events we bring in, but even someone who seems to defy the odds might be the one a million that gets lucky with a string of guesses. You flip the coin enough times and once in a while you will get seven heads in a row. It’s not expected, but it is predicted by the laws of chance. Likewise with predicting how many hurricanes we’ll have next year or what stocks to buy or sell this year.

The illusion of skill refers to the belief that skill, not chance or luck, accounts for the accuracy of predictions of things that are unpredictable, such as the long-term weather forecasts one finds in farmers’ almanacs and the predictions of market gurus about the long-term ups and downs of the stock market. The illusion of skill also accurately describes the apparent accuracy of remote viewers. Given all the guesses remote viewers make about what they claim to see telepathically, chance alone would account for some of those guesses being somewhat accurate. Much of the accuracy ascribed to remote viewers, however, is due to the liberal and generous interpretations given by themselves or “experts” of their vague and ambiguous descriptions of places or things. Also, subjective validation accounts for the illusion of skill of “experts” in such fields as palm reading, mediumship, astrology, and criminal profiling.
Stock gurus–people who predict the rise and fall of the price of stocks and have large numbers of people who act on their predictions–are essentially part of an entire industry “built largely on an illusion of skill” (Daniel Kahneman, Thinking, Fast and Slow, p. 212). No market guru has gone broke selling advice, however, despite the fact that market newsletters are–in the words of William A. Sherden–”the modern day equivalent of farmers’ almanacs” (The Fortune Sellers, p. 102). In 1994, the Hurlbert Financial Digest found that over a five-year period only one out of 108 market-timing newsletters beat the market. You might think that that one did so because of skill, but you’d be wrong. Chance alone would predict that more than one out of 108 would beat the market.

The illusion of understanding occurs frequently due to selection bias and confirmation bias. By selecting only data that support one’s position and ignoring relevant data that would falsify or compromise one’s position, one can produce a convincing but misleading argument. By seeking only examples that confirm one’s belief and by ignoring examples that disconfirm it or reveal the insignificance of the data you’ve put forth, one can easily create the illusion of understanding. The illusion of understanding is particularly prominent in the field of economic forecasting.
Think about it. If stock analysts could really beat the market consistently, wouldn’t they be stinking rich? Do you really think they are a clan of benevolent elves whose only goal is to help people like you get rich from their technical advice? Their cousins appear in infomercials all the time, telling stories about unfathomable riches that await you if you invest in their program. That’s how they make their money: not by using their program, but by selling it to others!
