Does Cleanliness Influence Moral Judgments? – Social Psychology – Volume 45, Number 3 / 2014 – Hogrefe Publishing

See on Scoop.itBounded Rationality and Beyond

Abstract

Schnall, Benton, and Harvey (2008) hypothesized that physical cleanliness reduces the severity of moral judgments. In support of this idea, they found that individuals make less severe judgments when they are primed with the concept of cleanliness (Exp. 1) and when they wash their hands after experiencing disgust (Exp. 2). We conducted direct replications of both studies using materials supplied by the original authors. We did not find evidence that physical cleanliness reduced the severity of moral judgments using samples sizes that provided over .99 power to detect the original effect sizes. Our estimates of the overall effect size were much smaller than estimates from Experiment 1 (original d = −0.60, 95% CI [−1.23, 0.04], N = 40; replication d = −0.01, 95% CI [−0.28, 0.26], N = 208) and Experiment 2 (original d = −0.85, 95% CI [−1.47, −0.22], N = 43; replication d = 0.01, 95% CI [−.34, 0.36], N = 126). These findings suggest that the population effect sizes are probably substantially smaller than the original estimates. Researchers investigating the connections between cleanliness and morality should therefore use large sample sizes to have the necessary power to detect subtle effects.

Using Behavioral Economics for Product Design | ideas42

See on Scoop.itBounded Rationality and Beyond

Design is about solving problems, and great design is about solving hard problems successfully. At ideas42 we’ve found that incorporating insights from behavioral economics at every stage of the design process can yield amazing results – whether solving problems in health, energy usage, or economic development.We’re just wrapping up a project looking at the design of microsavings products in the Philippines, working with Grameen Foundation and CARD Bank. Our re-designed products had significant positive effects in a randomized controlled trial, and this post will take you through our design process and share some of the insights we gained during the course of this project.

The importance of stupidity in scientific research

See on Scoop.itBounded Rationality and Beyond

I recently saw an old friend for the first time in many years. We had been Ph.D. students at the same time, both studying science, although in different areas. She later dropped out of graduate school, went to Harvard Law School and is now a senior lawyer for a major environmental organization. At some point, the conversation turned to why she had left graduate school. To my utter astonishment, she said it was because it made her feel stupid. After a couple of years of feeling stupid every day, she was ready to do something else.

I had thought of her as one of the brightest people I knew and her subsequent career supports that view. What she said bothered me. I kept thinking about it; sometime the next day, it hit me. Science makes me feel stupid too. It’s just that I’ve gotten used to it. So used to it, in fact, that I actively seek out new opportunities to feel stupid. I wouldn’t know what to do without that feeling. I even think it’s supposed to be this way.
