Society’s disapproval of alcohol, tobacco and gambling means that some investors -- mostly public institutions -- lose out while other investors gain on these undervalued “sin stocks,” according to a study conducted by the Sauder School of Business at the University of British Columbia.
Sauder Prof. Marcin Kacperczyk and co-author Prof. Harrison Hong of Princeton University analyzed stock markets and the impact they feel from society’s framework of morals, traditions and laws.
“While sinful stocks aren't necessarily good for the soul, they do deliver higher returns,” says Kacperczyk, adding…
People watching the Super Bowl who saw how much they had already eaten -- in this case, leftover chicken-wing bones -- ate 27 percent less than people who had no such environmental cues, finds a new Cornell study.
The difference between the two groups -- those eating at a table where leftover bones accumulated compared with those whose leftovers were removed -- was greater for men than for women.
"The results suggest that people restrict their consumption when evidence of food consumed is available to signal how much food they have eaten," said Brian Wansink, the John S. Dyson Professor of…
Most people want to be normal. So, when we are given information that underscores our deviancy, the natural impulse is to get ourselves as quickly as we can back toward the center.
Marketers know about this impulse, and a lot of marketing makes use of social norms. This is especially true of campaigns targeting some kind of public good: reducing smoking or binge drinking, for example, or encouraging recycling. The problem with these campaigns is that they often do not work. Indeed, they sometimes appear to have the opposite of their intended effect.
Why would this be? Psychologist Wesley…
Will you lose weight and keep it off if you diet? No, probably not, UCLA researchers report in the April issue of American Psychologist, the journal of the American Psychological Association.
"You can initially lose 5 to 10 percent of your weight on any number of diets, but then the weight comes back," said Traci Mann, UCLA associate professor of psychology and lead author of the study. "We found that the majority of people regained all the weight, plus more. Sustained weight loss was found only in a small minority of participants, while complete weight regain was found in the majority.…
It’s the seventh game of the World Series — bottom of the ninth inning, your team is down 4-3 with runners on second and third — and you’re on deck. You watch as your teammate gets the second out. That means you’re up with a chance to win a championship for your team...or lose it.
You’re known as a clutch hitter, and you’ve hit safely in 22 straight games — an impressive streak to be sure. But as you step into the batter’s box, your hands are sweating and your mind is racing. You think about the last time you faced this pitcher and the curveball he threw to strike you out. You look at him…
From the Shangri-La Diet forums:
This is week 5 for me, and I have lost 7 pounds so far.
I am a 37 year old mother of two — 5′6″ and started at 191 — the heaviest I have ever been in my non-pregnant life, with a BMI that fell in the “obese” category. I heard about Shangri-La from another woman, whom I dislike. I thought the whole thing sounded ridiculous, so I set out to prove her wrong. I replaced the two sodas I used to drink each day with two cups of sugar water, each 12 oz and 140 calories, exactly the same as the soda. This meant I was not changing my diet at all (other than removing the…
What would large women think if a dress sold for lower cost to women of smaller sizes?
Common sense says this would turn them off.
But swimmers react well to items claimed to improve speed if they know the product is given away free to Olympic swimmers.
If you perceive the person getting the good deal as being smarter than you, you are okay with it. You are even more likely to pay full price.
Alison K. C. Lo and marketing professors John Lynch and Richard Staelin explain why in the article "How to Attract Customers by Giving Them the Short End of the Stick," published in the February…
This post is about an article by Schacter et al (pdf) regarding how the constructiveness of memories may crucially be due to the need to simulate future scenarios. But before I go to the main course, I would like to touch upon a starter: Jeff Hawkins Heirarchical Temporla Memory (HTM) hypothesis. I would recommend that you watch this excellent video. As per Jeff Hawkins, we humans are basically prediction machines, constantly predicting the external causes and our responses to them. Traditionally, the behaviorist account has been that we are nothing but a bundle of associations- either…
Playground roughhousing has long been a tradition of children and adolescents, much to the chagrin of several generations of parents who worry that their child will be hurt or worse, become accustom to violence and aggression. But animal research may paint a different portrait of rough and tumble play; one that suggests that social and emotional development may rely heavily on such peer interaction.
In an article published in the April issue of Current Directions in Psychological Science, Sergio and Vivian Pellis of the University of Lethbridge reviewed multiple studies involving animals,…
Psychiatric researchers at The Zucker Hillside Hospital campus of The Feinstein Institute for Medical Research have uncovered evidence of a new gene that appears to increase the risk of developing schizophrenia, a disorder characterized by distorted thinking, hallucinations and a reduced ability to feel normal emotions..
Working in conjunction with researchers at the Harvard Medical School Partners Center for Genetics and Genomics in Boston, MA, the Zucker Hillside team utilized a cutting-edge technology called whole genome association (WGA) to search the entire human genome in 178 patients…
