Cognitive Bias

Wade’s put together a nice list of 26 common cognitive biases.

  1. Bandwagon effect - the tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink, herd behaviour, and manias. Carl Jung pioneered the idea of the collective unconscious which is considered by Jungian psychologists to be responsible for this cognitive bias.
  2. Bias blind spot - the tendency not to compensate for one’s own cognitive biases.
  3. Choice-supportive bias - the tendency to remember one’s choices as better than they actually were.
  4. Confirmation bias - the tendency to search for or interpret information in a way that confirms one’s preconceptions.
  5. Congruence bias - the tendency to test hypotheses exclusively through direct testing.
  6. Contrast effect - the enhancement or diminishment of a weight or other measurement when compared with recently observed contrasting object.
  7. DĂ©formation professionnelle - the tendency to look at things according to the conventions of one’s own profession, forgetting any broader point of view.
  8. 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.
  9. Endowment effect - the tendency for people to value something more as soon as they own it.
  10. 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.
  11. 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.
  12. Illusion of control - the tendency for human beings to believe they can control or at least influence outcomes which they clearly cannot.
  13. Impact bias - the tendency for people to overestimate the length or the intensity of the impact of future feeling states.
  14. Information bias - the tendency to seek information even when it cannot affect action.
  15. Loss aversion - the tendency for people to strongly prefer avoiding losses over acquiring gains (see also sunk cost effects)
  16. Neglect of probability - the tendency to completely disregard probability when making a decision under uncertainty.
  17. Mere exposure effect - the tendency for people to express undue liking for things merely because they are familiar with them.
  18. Omission bias - The tendency to judge harmful actions as worse, or less moral, than equally harmful omissions (inactions).
  19. 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.
  20. Planning fallacy - the tendency to underestimate task-completion times.
  21. Post-purchase rationalization - the tendency to persuade oneself through rational argument that a purchase was a good value.
  22. Pseudocertainty effect - the tendency to make risk-averse choices if the expected outcome is positive, but make risk-seeking choices to avoid negative outcomes.
  23. Selective perception - the tendency for expectations to affect perception.
  24. Status quo bias - the tendency for people to like things to stay relatively the same.
  25. 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.
  26. Zero-risk bias - preference for reducing a small risk to zero over a greater reduction in a larger risk.

Charitable Searching

Just discovered Everyclick.com. It’s a nice idea. Half of their gross revenue goes to charities.

“everyclick allocates 50% of its gross revenue to charity each month. Each active charity receives a proportion of that sum equivalent to the proportion in which its supporters use the website relative to the supporters of other active charities. The activity of everyclick website users who do not select a specific charity will benefit all active charities on a pro rata basis.”



Where’s the challenge?

This caught my eye

“A lot of applications are designed to make things easy. Fun comes from challenge. It’s about taking risks and taking risks that are wrong,” says Areae president Koster … “If you look at eBay, a huge reason that it’s addictive is because you can lose. You get hardcore users who can swipe things from people in the last three seconds.”

And there’s me trying to explain to children that collaboration not competition is the way forward. Maybe I should rethink that. Collaboration is the best way to win?



Prisoners dancing to Radio Ga Ga

This had me transfixed.

Web Safety Presentation for Parents

Finally gotten round to slidesharing a presentation I did for some Unicorn Mums who were worried about what their children got up to online (and wanted some advice about how to go about it). It’s a general overview rather than anything too specific.

As Mr W says (commenting on this slightly depressing article in the Grauniad)

The real question, however, boils down to the amount of privacy you feel your own children are entitled to. In my own case, I am a friend on my own kid’s Bebos, and I’ve also installed imsafer… but neither of these was done without discussing it with the kids first. For me, that is the dividing line between acceptable and unacceptable surveillance…

Completely agree about the dividing line. For what it’s worth, here are the slides (with a few wangy fonts).

Burma Petition

After seeing this and reading this Facebook group (thanks to Andy and Euan pointing here) I’ve just signed up to this petition.

Enterprise 2.0: Employees and Evangelism

There’s a great article by Olivier over at Headshift.

Two things caught my eye:

Employees are the one who know which tools are relevant for doing their job more efficiently and we don’t have to impose and restrict them (to) a set of tools

and

Social computing for the organisation, call it Enterprise 2.0 if you want to be trendy, is a reality that needs to be evangelised, despite massive information available on the wild wild web

And there’s the rub. If people haven’t heard the Web 2.0 evangelist, then do they know what tools are relevant for doing their job?



Rethinking Digital Homework

From CNN

“Insoo has a difficult math problem as homework. He posts it up on Naver Knowledge iN, a popular online Q&A service with some 70 million entries. Within about 10 minutes of posting, someone chimes in with a good answer, and Insoo awards him with some “Knowledge Power” points — knowledge-based economy in action among 14-year-olds.”

Laurent remarks that Korea provides

“an opportunity for Europeans and Americans to have a preview of what their society might be in a near future. Most of the important technological trends start in Korea five years before they hit us. Think of citizen journalism (started by Ohmynews in 2000), social networking (Cyworld, 1999), or knowledge sharing websites (Naver Knowledge iN who became Yahoo Answers for us).”

And that sentiment seems to be backed up here

All of which presumably ties in with “bottom-up education”.

From a teacher’s perspective, I think it’s great news that children can find so many different sources of help. And it’s great that they stand a good chance at becoming more skilled in collaborating, co-operating and thriving in a knowledge market of sorts.

But.

Perhaps the homework scenario skews things a little? Education is about many things, but presumably a couple of the key goals are encouraging curiosity and fostering understanding. To go online to quickly get some answers so you can quickly finish your homework (and do well at it) is a wonderful skill, but I wouldn’t have thought it’s the goal of the homework exercise.

How, then, can we rejig homework to encourage all of the above - curiosity, understanding, and collaboration?

Well, step one might be to look at the research that homework helps academic achievement. I’ve just bought this to try and find out more, and Harris Cooper at Duke seems to have done some interesting work. Even if it does help, there are pros and cons:

“Most of what homework is doing is driving kids away from learning,” says education professor Harvey Daniels. Let’s face it: Most children dread homework, or at best see it as something to be gotten through. Thus, even if it did provide other benefits, they would have to be weighed against its likely effect on kids’ love of learning.

Step two might be to try to, ahem, make homework enjoyable. Get children using their collaborative skills and their own interests to fulfil that horrendously named thing, the learning objective. Perhaps we should be asking the children how they could learn more about, say, perimeters and area at home, online, together or all three.



Facebook users do what exactly?

[via Rodney’s tip off about Compete.com]

howfacebook-usersspendtime.jpg

A comment on Rodney’s blog - from Michael - made me think:

“those of us interested in growing on-line communities the message seems to be that setting up special interest groups is going to be less effective than developing a useful application”

If there are 3 types of communities - one of them the type that grows from shared activities, one from shared space and one from shared interest - then maybe Facebook is doing 1 and 2 and blogs are doing 3? Oversimple probably.

Top-down Education

Richard Sambrook [thanks Euan]:

John Chambers, CEO of Cisco, made a really good point at the Clinton Global Initiative:

He said the current education system of grades and exams puts people in competition with each other and is a top down command-and-control model. As the leader of one of the world’s biggest IT companies he believes future education should concentrate on networking and collaboration - which will support greater innovation and cross-discipline creativity. It will also, he said, attract talent. Call it Education 2.0 then…

I completely agree at University level, and perhaps 16+, when education becomes optional. But I’m not sure it’s an either or before then. I’m just a little suspicious of completely ditching the top down. And I do think broad brush statements about education and how we should do it need to be narrowed take into account the strengths and proclivities that we have as a result of our age.
