The intersection in question.
For two Fridays in June 2011, from 3 to 6 pm, two experimenters sat near an intersection in San Francisco and watched the cars. They arranged themselves so that drivers couldn’t see them, and every now and then, they recorded the make and physical appearance of a car and tried to guess the gender and age of the driver. As their chosen cars pulled up to the intersection, they kept track of which ones cut off others. Later, in another study, they positioned an experimenter at a crosswalk. They took note of which cars neglected to stop for the pedestrian.

Male cichlid fish apparently don’t like what they see in the mirror–in fact, they dislike their own reflections even more than enemy fish, according to new research published in Biology Letters.
“[The] fish readily attack other males as well as mirror images of themselves, posturing and lunging with the same aggression… the reflection-fighting males show heightened activity in [the amygdala,] a part of the brain associated with fear and other negative reactions in vertebrates, [Stanford University researchers] have found. Tangling with a real male doesn’t stir up that response.”
