The TV show Lie To Me focuses on the exploits of an expert in lie-detection as he solves perplexing crimes in his high-tech Washington laboratory. It’s actually fun to watch, especially since it appears to make some effort to get the science right (a real-life expert on lie-detection, Paul Ekman, serves as a science adviser…

Suppose your organization is interviewing candidates for an important job. Would it be better for one trusted person to have an extended interview with them, or for several people to talk to them for less time? How many people would you need to conduct the interviews? Would three be enough? Would ten be too many?…

Nalini Ambady has become famous for her research on “thin slicing,” the idea that ordinary people can make accurate judgments about others amazingly quickly. We’ve discussed work from her lab showing that people can accurately predict teaching ability by watching just six seconds of video of a teacher at work. Other judgments, like gender, race,…

If you’re a regular reader of Cognitive Daily, you’re relatively accustomed to seeing surprising things. Indeed, it’s gotten to the point where you might even expect it. You’ve seen optical illusions and videos that baffle the imagination. Yet most participants in psychology research studies aren’t aware of the many ways the mind can be “tricked.”…

In celebration of Thanksgiving in the U.S., I’m reposting this piece, originally posted in April, 2008. How often do you take time to reflect on the things you’re grateful for? Once a month? Once a week, at church, perhaps? Maybe you say “grace” at mealtime every day. But even prayers that do express gratefulness, such…

Recently a woman had her sick leave benefits based on a diagnosis of clinical depression terminated because of a few pictures she posted on her Facebook page showing her smiling at a birthday party and enjoying a trip to the beach. Was this a fair assessment of her medical condition? Probably not–people with clinical depression…

Who’s more “sociable,” men or women? Common sense says it’s women, right? And many research studies back this impression up: Women are more interpersonal, more connected, more interdependent than men. Women are more likely to share intimate information with each other than men. But is that really the whole story? There is also research suggesting…

The long-term effects of day care

When we were getting ready to have our first child, I decided that I would quit my job, work out of home as a freelancer, and take care of our baby while Greta finished graduate school. That worked well for about two years, but by the time Nora was born, we decided to hire a…

Take a look at this video from last night’s episode of Jon Stewart’s “The Daily Show.” If you’d like, you can skip past all the political snark to the 4:47 mark to watch Jon bring cognitive psychology into prime time (or at least latenight cable)! That’s right; you saw it: Jon Stewart mentioned the psychological…

Greta and I did our undergraduate studies at the University of Chicago, or as a commonly-sold T-shirt on campus put it, “where fun goes to die.” To say that Chicago didn’t emphasize academics over a social life is to deny that people literally lived in the library (a full-scale campsite was found behind one of…
