Smarter Every Year? Mystery of the Rising IQs
The Wall Street Journal: Are you smarter than your great-grandmom? If IQ really measures intelligence, the answer is probably a resounding “yes.” IQ tests are “normed”: Your score reflects how you did compared with other people, like being graded on a curve. But the test designers, who set the average in a given year at 100, have to keep “renorming” the tests, adding harder questions. That’s because absolute performance on IQ tests—the actual number of questions people get right—has greatly improved over the last 100 years. It’s called the Flynn effect, after James Flynn, a social scientist at New Zealand’s University of Otago who first noticed it in the 1980s.

Marzilli Ericson, John Myles White, David Laibson, and Jonathan D. Cohen People frequently make decisions that have both short- and long-term consequences. These decisions -- called intertemporal choices -- have often been explained using delay-discounting models; however, these models have not always accounted for some of the behaviors seen in decision-making experiments. The authors hypothesized that models based on heuristics may provide a superior way to account for performance on discounting tasks.

‘Inside Out,’ Pixar’s New Movie From Pete Docter, Goes Inside the Mind
The New York Times: John Lasseter, a notepad in hand, settled into his seat in a dimly lit screening room at Pixar headquarters here in July 2012. Mr. Lasseter, Pixar’s chief creative officer, was there to evaluate progress on “Inside Out,” a new film set inside an 11-year-old girl’s mind. Had the filmmaking team cracked the unusual concept? It did not take long for the air to frost over. “We got up and said, ‘We’re not going to show you a screening because the film is not working,’ ” recalled Pete Docter, who turned to “Inside Out” after his Oscar-winning “Up.” Talk about guts: Mr. Docter’s movie had already been in the works for more than two years at that point. “I saw John do this,” Mr.
