THE TECHNICAL DETAILS, TUTORIALS, WALK-THROUGHS A few posts back, we showed how classic decision making experiments are being replicated on Amazon’s insta-subject-pool otherwise know as Mechanical Turk (aka MT). After that, Steven Pinker, at the SJDM keynote, presented Mechanical-Turk-collected data on perceptions of whether the past or present is perceived as more violent. This week, […]
PREDICTING ELECTIONS FROM THE MOST IMPORTANT ISSUE FACING THE COUNTRY Andreas Graefe and Scott Armstrong have put forth a model that predicts the outcome of U.S. Presidential Elections based on the most important issue as seen by voters. It’s a good illustration of how one cue, if it’s a good one, can be effective for […]
A WHOLE NEW WORLD OF EXPERIMENTS NOW POSSIBLE Gabriele Paolacci sends along the following announcement. Decision Science News is also a fan of Amazon’s Mechanical Turk (or mturk as we insiders call it), and it and its colleagues at Yahoo! Research are actively using with the evolving methodology.

INCREASED CREATIVITY WHEN THINKING ABOUT DISTANT THINGS Decision Science News has nothing against a good word problem. Heck, there would be no field of Judgment and Decision Making if it weren’t for Kahneman & Tversky’s word problems. Here’s one A prisoner was attempting to escape from a tower. He found a rope in his cell […]
DIFFERENT PEOPLE USE DIFFERENT HEURISTICS: START IDENTIFYING STRATEGIES Decision Science News does not like arguments that ‘people’, on average, do (or do not) use a certain decision making strategy.

THE DECISION OF HOW TO SPEND TIME The neatest visualization of the last 30 days has to be this New York Times interactive graphic showing how different groups of people decide to spend their time. It is based on data from the American Time Use Survey. Play with it and read the related article. Decision Science […]
DRIVEN TO DISTRACTION The headline E-mails ‘hurt IQ more than pot’ caught our attention here at DSN. Reading the article, we see that the study is not about intelligence as a trait being affected by internet interruptions. It simply uses an IQ test as a measure, we suppose, of being able to think clearly. In […]
USING GRAPHICAL DISPLAYS TO COMMUNICATE TERRORISM RISKS Jon Baron sent over this timely article http://news.bbc.co.uk/1/hi/magazine/8153539.stm I like the way the author suggests visual representations (as above) to make the point. That particular representation seems vaguely familiar. I wonder if the author knows there’s been quite a bit of research done on it. 1) Sedlmeier, P., & Gigerenzer, […]
INCENTIVES TO STATE PROBABILITIES OF BELIEF TRUTHFULLY We have all been there. You are running an experiment in which you would like participants to tell you what they believe. In particular, you’d like them to tell you what they believe to be the probability that an event will occur. Normally, you would ask them. But […]
