In the biblical story in which two women bring a baby to King Solomon, both claiming to be the mother, he suggests dividing the child so that each woman can have half.
The human brain responds to being treated fairly the same way it responds to winning money and eating chocolate, UCLA scientists report. Being treated fairly turns on the brain's reward circuitry.

The ability to regulate emotions is essential to both mental and physical well-being. â€œConversely, difficulties with emotion regulation have been postulated as a core mechanism underlying mood and anxiety disorders,â€ according to the authors of a new study published in Biological Psychiatry on March 15th.
Researchers from EPFL and Caltech have made an important neurobiological discovery of how humans learn to predict risk. The research, appearing in the March 12 issue of the Journal of Neuroscience, shed light on why certain kinds of risk, notably financial risk, are often underestimated, and whether abnormal behavior such as addiction (e.g. to gambling or drugs) could be caused by an erroneous evaluation of risk.
The ups and downs of the stock market reflect investors' balance between greed and fear, goes an old saying.
