As the presidential campaigns refocus on November, they're zeroing in on digital domains. In fact, the Obama campaign has spent six times as much money advertising online as it has on TV so far, though that's certain to change.
And Republicans are fighting back with a new Facebook app called the "Social Victory Center." (You have to be a Facebook user to access the site.)
Newt Gingrich is officially out of the presidential race. The former House speaker said Wednesday that he's suspending his campaign, and he's ready to help the presumptive Republican nominee, Mitt Romney, battle President Obama. But Gingrich might have a more pressing problem: His campaign has about $4 million in debt.
In Gingrich's exit speech, he opened by thanking people — first his family, then his financial backers.
"I also want to single out, first of all, the over 179,000 donors who helped us at Newt.org and who helped make the campaign possible," he said.
For decades, teachers, managers and parents have assumed that the performance of students and employees fits what's known as the bell curve — in most activities, we expect a few people to be very good, a few people to be very bad and most people to be average.
The bell curve powerfully shapes how we think of human performance: If lots of students or employees happen to show up as extreme outliers — they're either very good or very bad — we assume they must represent a skewed sample, because only a few people in a truly random sample are supposed to be outliers.
