Practice Doesn’t Always Make Perfect, Study Suggests
U.S. News & World Report: Practice is an essential part of gaining excellence in a specific skill, but to become truly great other qualities must come into play, such as IQ or working memory, according to researchers who studied how practice affects the success of chess players. For the study, published in the October issue of Current Directions in Psychological Science, the researchers also considered earlier research and noted that practicing harder or longer doesn't compensate for the lack of other important traits relevant to a certain activity.

10 Examples of Everyday Evil
Discovery Channel: Consumer Wickedness We live in a consumerist culture that equates possessions with happiness. But where do they all come from? Bangladesh's garment workers, for one, who produce clothing for companies such as Gap and Levi-Strauss at a rate of 21 cents per hour [source: Richardson]. In March 2010, more than 20 workers in a Bangladeshi factory were killed in a fire due to poor safety standards [source: Hickman].

Are liberals and conservatives just taking different routes to happiness?

Conservatism makes people less likely to feel bad: Research shows that political conservatives are happier than liberals [Napier, J. L., & Jost, J. T. (2008).

“The Steroids of Scientific Competition”
A week or so ago, I wrote up some new research showing how easy it is for psychological scientists to falsify experimental results. The point of the report, published on-line in the journal Psychological Science, was not that researchers are deliberately, or mischievously, reporting bogus findings. The point was instead that commonly accepted practices for reporting and analyzing data can lead inadvertently to invalid conclusions.

Peace in our time?
The Daily Mail: Hear the good news! ‘We are living in the most peaceable era of our species’ existence!’ Well, you could have fooled me. Who says so? And why? The herald of reassurance is professor Steven Pinker, the Harvard psychologist with impressive books to his credit on how our minds work. He draws his conclusion - that human violence has declined amazingly, is still declining and may be on the way out - from a 700-page survey of the subject, packed with statistics, table after table and graph after graph. The professor writes as though he knows that I am not going to believe him.
