- As I’ve mentioned previously, sports will increase brain efficiency even in cases like walking across the street. Athletes process and make faster decisions than non-athletes. The interesting thing is that researchers tested this with what amounted to a video game. I predict that pro gamers would fare just as well as the athletes if given the same test.
- Can you spot criminals just by looking at their face? It turns out that sometimes you can. Out of 32 random young white guys with half having been convicted of a violent crime, most people will do better than chance in guessing which of them have committed a crime. I got 11 of 16 where the expected rate would be 8. They should repeat this study with other races and see if the results hold. Can non-blacks tell a convicted black criminal from a law-abiding one? What about Asians? I wonder if a study like this would even have much meaning in other contexts – like in Japan, the home of no looters ever. I don’t think China or Taiwan had much looting after their quakes either.
