 Confirmation Bias

Numerous studies have demonstrated that people generally give an excessive amount of value to confirmatory information, that is, to positive or supportive data. The "most likely reason for the excessive influence of confirmatory information is that it is easier to deal with cognitively" (Gilovich 1993). It is much easier to see how a piece of data supports a position than it is to see how it might count against the position. Consider a typical ESP experiment or a seemingly clairvoyant dream: ...

 Fox News and the Dangers of Confirmation Bias

So why not just say, “I may have mischaracterized things a few times” and move on? To understand why that’s impossible, you have to understand O’Reilly’s persona and the function he serves for his viewers. The central theme of The O’Reilly Factor is that the true America, represented by the elderly whites who make up his audience (the median age of his viewers is 72) is in an unending war with the forces of liberalism, secularism, and any number of other isms. Bill O’Reilly is a four-star gen...

 Human Memory, Computer Memory

Almost all of those limits start with a peculiar fact about human memory: Although we are pretty good at storing information in our brains, we are pretty poor at retrieving it. We can recognize photos from our high school yearbooks decades later, yet find it impossible to remember what we had for breakfast yesterday. Faulty memories have been known to lead to erroneous eyewitness testimony (and false imprisonment), to marital friction (in the form of overlooked anniversaries), and even death ...

 Reasons to Give Up News

News misleads. News leads us to walk around with the completely wrong risk map in our heads. So terrorism is over-rated. Chronic stress is under-rated. The collapse of Lehman Brothers is overrated. Fiscal irresponsibility is under-rated. Astronauts are over-rated. Nurses are under-rated. News is irrelevant. Out of the approximately 10,000 news stories you have read in the last 12 months, name one that – because you consumed it – allowed you to make a better decision about a serious matter aff...

 The Method of Multiple Working Hypotheses

It will be observed that the distinction [between hypothesis and theory] is not such as to prevent a working hypothesis from gliding with the utmost ease into a ruling theory. Affection may as easily cling about a beloved intellectual child when named as a hypothesis as if named a theory, and its establishment in the one guise may become a ruling passion very much as in the other. The historical antecedents and the moral atmosphere associated with the working hypothesis lend some good influen...

By maintaining many hypotheses, the scientist does not fall in love with one over the others and fall into the trap of confirmation bias.
