Another nail in the coffin of traffic “psychology”

Minicosm (Metro, 4 May 11) reported: “We have an in-built system of fair play, a new study has found [no reference given]. Subjects were asked how they would divide a sum of money. Swedish researchers found that if someone suggested an uneven split, the amygdala region of the brain would light up and the person making the unfair suggestion would be punished, even if it meant the group suffered.” I see a parallel with road rage. Road-users suffer the fallout of a defective system, while the puppeteers get away with murder.
