Our brain's organization biases it towards preferences and decisions that enhance our survival and the quality of our life. These biases are evident during the current presidential campaign, and five underlying brain properties seem especially significant.

A Social Species
Humans are a social species and this gives us an important advantage over species in which individuals only get together to mate. Our individual capability on any given task is limited, but since others may exceed our personal limit, the combined capability of a collaborative group will be greater than that of any individual in it. Since we function within a complex system of informal and formal collaborations (such as friendships and governments), we tend to appreciate virtuosos and leaders whose capabilities exceed our own, and so expand our possibilities.

The recent Olympic Games thus identified individuals and teams in the upper range of human movement capability, and the current presidential campaign will select the management team that will administer our complex federal government for the next four years.
