What will people do for money?

(PhysOrg.com) -- At the April 4, 2011 annual meeting of the Cognitive Neuroscience Society the subject of moral dilemmas and what people would really do was addressed. In a study presented by Oriel FeldmanHall of Cambridge University shows that when it comes to moral studies, hypothetical scenarios do not work to determine the complexities of what people’s real decisions would be.

FeldmanHall’s study showed that what people say they will do in a given situation and what they really do are two very different things. If given a hypothetical situation of a choice of giving someone an electrical shock for money or walking away, most people answered they would never be able to inflict pain on another person.

However, in a real-life scenario, with real money and real electric shocks, the actions were much different. In FeldmanHall’s study, subjects were placed in an MRI scanner and then given the choice to either administer an electrical shock to a person located in another room and make money (one British pound) or not inflict pain and receive no money. They also broke down that one pound into percentages based on the severity of the shock, so they would receive the full pound for administering a severe shock and less for more mild shocks.

The subject in the MRI was shown a video of the person receiving the shock and would either see just the person’s hand jerk or be shown both the hand jerk and the person’s face. Each participant was given the choice to shock another person 20 times, with the opportunity to make 20 pounds.

In the hypothetical scenario, 64 percent of participants said they would never administer a shock to someone else for money. However, in the real world that number changed, and in a big way. When faced with real money, 96 percent chose to shock the person in the other room for .

What seemed to make the difference in how many of those 20 chances the participants took was what video they were watching. On average, those watching just the hands jerk walked away with 15.77 pounds, but those watching the faces as well, left with only 11.55 pounds.

The study also showed that when these individuals were presented with a moral dilemma, they showed heightened activity in the insula, a part of the brain believed to be attached to emotion. It is this lack of emotion and real dilemma that FeldmanHall believes is what is missing in traditional hypothetical dilemmas.

The hope of using these types of studies is to determine how the brain dictates compassion and moral behavior in individuals.
