Prayers for Tim.

Get well soon, Tim Johnson. Oof, talk about terrible news on several levels. One hopes the Senator will make a full and complete recovery after his AVM surgery, and we won’t have to think too deeply about the possibility of a Senate turnover. Fortunately, there seems to be a good deal of precedent for long absences from the chamber — my first thought (other than Nate Fisher and Narm!) was Charles Sumner’s three-year absence after the caning, but there are apparently many 20th century examples too.

If you’re feeling sinister.

By way of Dangerous Meta, a new NBER working paper finds that left-handed men make 13-21% more than their right-handed counterparts (although the same doesn’t apply for women.) “The study is the latest to suggest there’s something special about lefties. Other researchers have found that left-handers are overrepresented on university faculties, as well as among gifted students, artists and musicians.” Update: Slate‘s Joel Waldfogel considers the results.

Bowling alone.

“‘People are increasingly busy,’ said Margaret Gibbs, a psychologist at Fairleigh Dickinson University. ‘We’ve become a society where we expect things instantly, and don’t spend the time it takes to have real intimacy with another person.’” CNN delves into the broadening landscape of American loneliness, which, according to the NYT, is becoming particularly acute among middle-aged men without college degrees.

Fair and Balanced in Florida.

“‘Our estimates imply that Fox News convinced 3 to 8 percent of its audience to shift its voting behavior towards the Republican Party, a sizable media persuasion effect,’ said Stefano DellaVigna of the University of California at Berkeley and Ethan Kaplan of Stockholm University.” Also in the same vein, the Post‘s Richard Morin summarizes a new academic study on the “Fox News Effect”, which, according to its authors, may have “produced more than 10,000 additional votes for Bush” in Florida in 2000.

Dance Dance Evolution.

“‘People are born to dance,’ Ebstein told Discovery News. ‘They have (other) genes that partially contribute to musical talent, such as coordination, sense of rhythm. However, the genes we studied are more related to the emotional side of dancing — the need and ability to communicate with other people and a spiritual side to their natures that not only enable them to feel the music, but to communicate that feeling to others via dance.” Looks like the Red Shoes are just a placebo — According to recent research at Hebrew University’s Scheinfeld Center for Genetic Studies, some people are just hardwired to dance. Now if only they could figure out why some people start conga lines or insist on breaking into the Electric Slide. (Via Dangerous Meta.)

Hardwired?

It’s an ugly day for voter rationality in today’s New York Times. According to a new study by several political scientists, our political predispositions may be genetic (and last summer’s Zellout may have been the result of a lingering discordance between genetic and environmental factors in Miller’s make-up.) Whatsmore, we seem to choose our elected leaders immediately by their physical attributes, namely a general look of competence: “Both babies and baby-faced adults share certain characteristics: round faces, large eyes, small noses, high foreheads, and small chins. No one trusts the competence of a baby, and few, apparently, trust that of an adult who looks like one.” (Don’t lose heart, fellow advocates of an informed and capable electorate — There’s obviously a huge gaping hole in this latter theory.)

Lacuna, Inc?

“Sun is shinin’ in the sky, there ain’t a cloud in sight…” Life imitates art as scientists attempt to achieve “therapeutic forgetting”, a.k.a. the focused erasure of memories. Right now, though, they haven’t got much past dulling the edge off old remembrances. “Our experiences and our memories in a lot of ways define us and define who we are,” notes Stanford ethicist David Magnus about the field, “[a]nd so that’s a scary step to go down. We should be very careful about going down a path that could lead to a serious alteration of the core essence of our identities.” Can you hear me? I don’t want this anymore, I want to call it off!
