‘Drawings may indicate later intelligence,’ according to new study
The Washington Post: Don’t throw away your kid’s stick figure drawings just yet. Researchers found a “moderate correlation” between drawing and intelligence, a link that “seemed to be influenced by genes,” according to a study by the Institute of Psychiatry at King’s College London. The test centered on identical and nonidentical twins, with 15,504 children participating. Each child was asked to draw a picture of a child and then given verbal and nonverbal intelligence tests. The children were first tested when they were 4 years old, and again 10 years later at age 14.

Tooth Fairy feels the pinch after overspending
USA Today: The Tooth Fairy is holding her purse strings a bit tighter. She left 8% less this year - or an average of $3.40 for every lost tooth she finds under a pillow - down from $3.70 in 2013, according to a survey from Visa out Thursday. Still, she's leaving more than she did in 2012 before tooth inflation rose 23% from 2012 to 2013. "She's had her wings clipped a little bit," says Jason Alderman, Visa's vice president of global financial education.

Is Racism Just a Form of Stupidity?
The Huffington Post: I think that a lot of us are shying away from an obvious truth: that the kind of blatant racial prejudice we are witnessing in Ferguson, Missouri, has everything to do with stupidity. I'm talking about low intelligence, lack of mental ability, cognitive rigidity. Racists may be a lot of other things -- hateful, insecure -- but let's not sugar-coat what most fair-minded thinkers believe in their hearts: A person of intelligence cannot embrace such authoritarian and racist views. Intelligence is a scientific concept, something scientists can measure, and have for a long time.

The Power of Two: Why Sharing Is Better
My wife and I watch a lot of movies at home. It’s one of our favorite pastimes. I also watch a fair number of movies by myself, if my wife is out of town or busy with something else. Both of these activities are enjoyable, and I like the occasional solitude. But I enjoy the movies more when we watch them together, and I’ve often wondered why. It’s not that we talk during the movie, or communicate in any way really. We’re mostly silent, but we’re side-by-side, and that in itself seems to enhance the experience of watching a movie. Psychological scientists, it turns out, have noticed this phenomenon, too, and find it intriguing.
