The Bad Science Reporting Effect
The Chronicle of Higher Education: The press coverage of the so-called “QWERTY effect” in early March left me somewhat worried that it is so easy to publish bad science, but absolutely appalled at the state of science reporting. The alleged effect is that average scores on reported positivity or happiness associations are slightly higher for words having more letters from the right-hand side of the keyboard. By late on March 8, Mark Liberman at Language Log had re-examined the relevant statistics, noting that the effect is extremely weak. It could explain about a 10th of one percent of the variance in positive vs. negative affective judgments about words, if it existed.

Keep your cool with wrong hand
Yahoo! India: People who find it difficult to rein in their aggression and yell at others even for silly mistakes can benefit by simply using the wrong hand in daily life and thereby practice self control, suggests a study. According to Thomas Denson of the University of New South Wales, right handers should get into the habit of using a computer mouse, stirring a cup of coffee or opening a door with their left hand and left-handers should do the opposite, the Daily Mail reported. Training yourself to use the wrong hand seems to act as practice for other kinds of self control, such as being polite. Just two weeks of the exercises reduce the tendency to act on impulse, he says.

Agreement of Alcohol Use Among Roommates
In case you missed it, the cameras were rolling at the APS 23rd Annual Convention in Washington, DC. Watch Grace Jackson from New York University present her poster session research on “Agreement of Alcohol Use: A Year-Long Study of College Roommates.” Grace Jackson is interested in researching how relationships progress over time. Jackson and coauthors Sean P. Lane (New York University), Gertraud Stadler (Columbia University),Niall Bolger (Columbia University), andPatrick E. Shrout (New York University) studied 293 pairs of undergraduate roommates (N = 586). They found that roommates are generally pretty good at reporting trait-level, a.k.a.

In the Mood for Some Pi(e)?
Thanks to computer-driven calculations, we know the ratio of the circumference of any circle to its diameter goes on past one trillion digits. But since the 18th century, we’ve just called this behemoth number, Pi (π). And since 1988, people have been celebrating Pi Day on March 14th (3/14). Daily Observations has a few suggestions for celebrating Pi Day the psychological-science way: Don’t use your high school geometry skills very often? They might be helping you out anyway. A new article in Current Directions in Psychological Science suggests that “numeracy” — like literacy, but for numbers instead of letters — actually helps you make more informed decisions.

Health Psychology: The Politics of Health
Politics and health may seem like an unlikely pair. Yet, a brief glance into history shows us that public policies contribute mightily to individual health outcomes. Early examples of this relationship are found in the development of public and private sanitation systems in the Indus Valley region in 2000 BCE, the development of public water systems in ancient Greece and later Rome, and public health studies of the relationship between sewer systems and fevers in England in the mid-1800s.

Just 60 Seconds of Combat Impairs Memory
Just 60 seconds of all-out physical exertion in a threatening situation can seriously damage the memories of those involved for many details of the incident, according to a new study of police officers. Police officers, witnesses and victims of crime suffer loss of memory, recognition and awareness of their environment if they have had to use bursts of physical energy in a combative encounter, according to scientists.
