Reciprocity behaviors differ as to whether we seek cerebral vs. limbic system rewards

This 2014 Japanese human study showed which brain areas were involved in indirect reciprocity. It was mainly cerebral areas that were active in:

“Reputation-based reciprocity, in which they help others with good reputations to gain good reputations themselves.”

Previous studies found much the same with direct reciprocity, where an individual was reimbursed by someone who directly owed them a debt of cooperation.

It was mainly limbic system areas that were active in:

“Pay-it-forward reciprocity, in which, independently of reputations, they help others after being helped by someone else.”

The researchers compared and contrasted self-interested behaviors of:

  • direct reciprocity and
  • reputation-based reciprocity,

both of which sought rewards in the cerebrum, with empathetic behaviors of:

  • pay-it-forward reciprocity,

where the subjects sought emotional rewards in the limbic system.

Want empathy from your therapist? Don’t give a scientific explanation of your condition

This 2014 Yale study found that providing scientific explanations of patients’ conditions actually REDUCED an important part of what patients may need from therapists – empathy.

That finding summed up the malaise throughout the current dog-and-pony-show approaches in psychotherapy, where:

  • Efforts to treat symptoms are maximized, and approaches to treat causes are minimized;
  • The therapist is in charge, not the patient;
  • The cerebrum is the all-in-all, while the limbic system and instinctual parts of the patient’s brain that drive behavior are suppressed.
