Enhancing the Efficacy of Teacher Incentives through Loss Aversion: A Field Experiment
Paying teachers bonuses in advance and threatening to take them back if students' performance doesn't improve seems to improve teaching quite a bit - paying them bonuses after the fact doesn't seem to have the same effect. I wonder if the same would apply to executive pay.
Half-Assed Media Speculation About the Batman Shooter
The Batman shooting are the fault of the Tea Party, the weakening of Judeo-Christian values, bullying, Trekkies, violent video games, Occupy Wall Street, and/or ...
Immigration to Australian jail
Mandatory sentencing for illegal immigrants appears to actually be boosting the number that show up on Australia's shores. Why? Free medical and dental care in jail, combined with pay for prison work amounting to about 10x what they could earn at home, mixed with comparative safety.
Exposure to Sexual Content in Popular Movies Predicts Sexual Behavior in Adolescence
"Researchers point out that it is important to remember that this research cannot conclude a direct causal effect of movies on sexual behavior." ... there's still that causation vs. correlation thing but I'd argue that the study's conclusions are somewhat to be expected.

When the pot calls the kettle black

I mentioned a while back that I wasn't a big fan of the way that Mark Regenerus did his research, yet it seems as though there are a lot of instances of the pot calling the kettle black. In that article I also mentioned the following bit of an LA Times piece:

[N]o scholarly research, including the Regnerus paper, has ever compared children of stable same-sex couples to children of stable different-sex couples, in part because an adequate sample size is hard to come by.

Yet, the level of opposition that he's receiving, though unsurprising, although seems a bit unwarranted and hypocritical. To quote a piece from the Chronicle of Higher Education entitled An Academic Auto-da-Fé:

His sample [population] was a clear improvement over those used by most previous studies on this topic. ... Those who are attacking Regnerus cannot admit their true political motives, so their strategy has been to discredit him for conducting "bad science." That is devious. His article is not perfect—no article ever is. But it is no scientifically worse than what is routinely published in sociology journals. Without a doubt, had Regnerus published different findings with the same methodology, nobody would have batted a methodological eye. Furthermore, none of his critics raised methodological concerns about earlier research on the same topic that had greater limitations, which are discussed in detail in the Regnerus article. Apparently, weak research that comes to the "right" conclusions is more acceptable than stronger studies that offer heretical results.

Try, e.g., this article which includes:

based strictly on the published science, one could argue that two women parent better on average than a woman and a man, or at least than a woman and man with a traditional division of labor. Lesbian coparents seem to outperform comparable married heterosexual, biological parents on several measures, even while being denied the substantial privileges of marriage.

The typical problem in these sorts of studies are things like tiny sample groups and biased selection of research subjects.

A second article article in the Chronicle of Higher Education notes the following:

Regnerus disclosed the Bradley Foundation and Witherspoon Institute’s sponsorship of the study, acknowledging their conservative pedigrees and asserting that “the funding sources played no role at all in the design or conduct of the study, the analyses, the interpretations of the data, or in the preparation of this manuscript.”
His disclosure squares with the code of ethics of the American Sociological Association, which does not prohibit sociologists from taking research funding from any particular funding source as long as the researcher discloses that relationship.
However, UT-Austin's standard appears to be stricter. “It is the policy of the University of Texas that research is conducted with integrity and free from any actual or apparent institutional or personal conflict of interest,” says the university’s Compliance and Ethics Guide. Texas researchers, the policy says, “must insure that there is no reasonable expectation that the design, conduct, and reporting of the research will be biased by any significant financial interest of an investigator responsible for the research or other educational activity.”

If they actually applied UT-Austin's Compliance and Ethics guidelines in the same way as some are arguing they should be applied to Regnerus, you'd have to wonder just how many of his opponents would also wind up in violation.

Skeptical about renewable energy predictions? You should be.
"we weren’t the only ones that were timid in our predictions of renewable electricity’s potential. Based on data collected by the Renewable Energy Policy Network for the 21st Century, many experts were way off on how wind and solar electricity would grow over the last decade." I wonder how much of this might be impeded by Europe's economic crisis (where they seem to be trimming back a bit on support for renewable energy) or China (where the government seems desperate to build to raise its GDP ... and build ... and build even if it means empty cities and the like)
How the Elites Built America’s Economic Wall
"the promise of a better life that once drew people of all backgrounds to rich places such as New York and California now applies only to an educated elite -- because rich places have made housing prohibitively expensive. ... there are two competing models of successful American cities. One encourages a growing population, fosters a middle-class, family-centered lifestyle, and liberally permits new housing. It used to be the norm nationally, and it still predominates in the South and Southwest. The other favors long-term residents, attracts highly productive, work-driven people, focuses on aesthetic amenities, and makes it difficult to build. ... The first model spurs income convergence, the second spurs economic segregation."
Dog collar clergy 'risk attack'
"National Churchwatch, which provides personal safety advice, says vicars are attacked more often than professions such as GPs and probation officers. ... In the past decade, five vicars have been murdered. And a 2001 academic study also found that 12% of clergy had suffered some form of violence. In a survey of 90 London clergy Mr Tolson carried out last year, nearly half said they had been attacked in the previous 12 months." (The state Church of England seems to have more or less given up on believing anything distinctively Christianity but still...)
