Daniel Finkelstein: Why do people disbelieve in global warming? | Daniel Finkelstein - Times Online

  • The hypothesis turned out to be correct. Some Conservatives answered, largely supporting the monetary control Bill and opposing the agricultural trade Bill. Some Labour supporters answered, revealing the opposite bias. But overall there was a weak but distinct relationship between less political knowledge and greater willingness to answer.
  • The second hypothesis was more startling. The authors believed that the more political knowledge you believe you have (as opposed to actually have), the more likely you were to answer. And this turned out to be strongly true. It was also true that if asked about your political knowledge before being asked the other questions, you were even more likely to respond on the fictitious bills.

Bob Sutton: Intuition vs. Data-Driven Decision-Making: Some Rough Ideas

  • The trouble with intuition is that we now have a HUGE
    pile of research on cognitive biases and related flaws in decision-making that
    show "gut feelings" are highly suspect.  Look-up confirmation bias --- people have a
    very hard time believing and remember evidence that contradicts their beliefs. There
    is also the fallacy of centrality, a lot more obscure, but important in that
    people -- especially those in authority -- believe that if something important
    happens, they will know about it.     
  • when people have the mindset to "act on their beliefs, while
    doubting what they know," so that they are always looking for
    contradictory evidence, encouraging those around them to challenge what they
    believe, and constantly updating (but always moving forward), then I think that
    intuition -- or acting on incomplete information, hunches, conclusions -- is
    right.

Technology Review: Blogs: Predictably Irrational: A Fictional historic view of the future

  • this painful and expensive lesson caused businesses and policy makers to recognize three main lessons: 1) human beings have many irrational tendencies, fallibilities, and quirks; 2) we often have bad intuitions and a limited understanding of our irrational tendencies and; 3) if we want to create effective policies we shouldn’t rely on our intuitions for finding recommendations nor on the assumption that people behave rationally; instead, we should ground our recommendations in how people actually behave.
  • After a few years spent watching in awe as business productivity improved,  government policymakers followed suit by implementing experiments with the Education-Forward Initiative (formerly No Child Left Behind). These experiments showed that basing teachers’ salaries on student performances had minor short-term benefits and caused substantial long-term damage on teacher and student motivation; that creating interest in education was more important than grades; and that shifting the curriculum focus from calculus to statistics and probability had a wonderful impact on students.

Web Use Project: Cross-Ideological Discussions among Conservative and Liberal Bloggers

  • With the increasing spread of information technologies and their potential to filter
    content, some have argued that people will abandon the reading of dissenting political opinions in favor of material that is closely aligned with their own ideological position. We test this theory empirically by analyzing?both quantitatively and qualitatively?Web links among the writings of top conservative and liberal bloggers. Given our use of novel methods, we discuss in detail our sampling and data collection methodologies. We find that widely read political bloggers are much more likely to link to others who share their political
    views. However, we find no increase in this pattern over time. We also analyze the
    content of the links and find that while many of the links are based on straw-man arguments, bloggers across the political spectrum also address each others? writing substantively, both in agreement and disagreement.

Endowment effect - Wikipedia, the free encyclopedia

The endowment effect (also known as divestiture aversion) is a hypothesis that people value a good or service more once their property right to it has been established. In other words, people place a higher value on objects they own than objects that they do not. In one experiment, people demanded a higher price for a coffee mug that had been given to them but put a lower price on one they did not yet own.
