Healthbolt’s “26 Reasons What You Think is Right is Wrong” presents a list of cognitive biases. If you keep an eye open, you’ll notice a lot of these being exploited by various advertising and political propaganda.
A cognitive bias is something that our minds commonly do to distort our own view of reality. Here are the 26 most studied and widely accepted cognitive biases.
- Bandwagon effect – the tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink, herd behavior, and manias. Carl Jung pioneered the idea of the collective unconscious which is considered by Jungian psychologists to be responsible for this cognitive bias.
- Bias blind spot – the tendency not to compensate for one’s own cognitive biases.
- Choice-supportive bias – the tendency to remember one’s choices as better than they actually were.
- Confirmation bias – the tendency to search for or interpret information in a way that confirms one’s preconceptions.
- Congruence bias – the tendency to test hypotheses exclusively through direct testing.
- Contrast effect – the enhancement or diminishment of a weight or other measurement when compared with recently observed contrasting object.
- Déformation professionnelle – the tendency to look at things according to the conventions of one’s own profession, forgetting any broader point of view.
- Disconfirmation bias – the tendency for people to extend critical scrutiny to information which contradicts their prior beliefs and uncritically accept information that is congruent with their prior beliefs.
- Endowment effect – the tendency for people to value something more as soon as they own it.
- Focusing effect – prediction bias occurring when people place too much importance on one aspect of an event; causes error in accurately predicting the utility of a future outcome.
- Hyperbolic discounting – the tendency for people to have a stronger preference for more immediate payoffs relative to later payoffs, the closer to the present both payoffs are.
- Illusion of control – the tendency for human beings to believe they can control or at least influence outcomes which they clearly cannot.
- Impact bias – the tendency for people to overestimate the length or the intensity of the impact of future feeling states.
- Information bias – the tendency to seek information even when it cannot affect action.
- Loss aversion – the tendency for people to strongly prefer avoiding losses over acquiring gains (see also sunk cost effects)
- Neglect of probability – the tendency to completely disregard probability when making a decision under uncertainty.
- Mere exposure effect – the tendency for people to express undue liking for things merely because they are familiar with them.
- Omission bias – The tendency to judge harmful actions as worse, or less moral, than equally harmful omissions (inactions).
- Outcome bias – the tendency to judge a decision by its eventual outcome instead of based on the quality of the decision at the time it was made.
- Planning fallacy – the tendency to underestimate task-completion times.
- Post-purchase rationalization – the tendency to persuade oneself through rational argument that a purchase was a good value.
- Pseudocertainty effect – the tendency to make risk-averse choices if the expected outcome is positive, but make risk-seeking choices to avoid negative outcomes.
- Selective perception – the tendency for expectations to affect perception.
- Status quo bias – the tendency for people to like things to stay relatively the same.
- Von Restorff effect – the tendency for an item that “stands out like a sore thumb” to be more likely to be remembered than other items.
- Zero-risk bias – preference for reducing a small risk to zero over a greater reduction in a larger risk.
“It is immoral to assign writing that will not be read by a human being.”
–John Warner on using automated feedback/grading software to assess student essays.
What do you think? Is using software to grade student essays a legitimate tool for reducing teacher workloads or is it something much worse? Let me know in the comments.
“I think it’s fair to say almost no one wants disruption. I think that what almost everyone does want is something better.” – Seth Godin
Depending on perspective, it is an author’s dream – or nightmare: Margaret Atwood will never know what readers think of the piece of fiction she is currently working on, because the unpublished, unread manuscript from the Man Booker prize-winning novelist will be locked away for the next 100 years.
Atwood has just been named as the first contributor to an astonishing new public artwork. The Future Library project, conceived by the award-winning young Scottish artist Katie Paterson, began, quietly, this summer, with the planting of a forest of 1,000 trees in Nordmarka, just outside Oslo. It will slowly unfold over the next century. Every year until 2114, one writer will be invited to contribute a new text to the collection, and in 2114, the trees will be cut down to provide the paper for the texts to be printed – and, finally, read.
