R&D for Lifetime of Life

Brain shape = personality.

In 1819, phrenology became popular when Franz Joseph Gall published his major book on the subject. The brain was divided into 27 different organs, each with a sepcific function ranging from being religious to a tendency to commit murder. The size of each was determined by measuring the bumps of the head.

Phrenology fell out of favour in the 20th century.

Prof Colin G DeYoung has found the 21st century replacement. Psychologists use the Big 5 (OCEAN) personality factors as the best description of our personality. And DeYoung has used MRI brain scans to show that the volume of certain areas of the brain corresponds to 4 of the Big 5 factors.

Neuroticism (negative emotion, anxiety, vulnerability, irritability), agreeableness (altruism, empathy, cooperation, politeness), conscientiousness (organization, industriousness, diligence, constraint) and extraversion (positive emotion, enthusiasm, sociability, assertiveness) all linked to specific brain areas.

Openness/Intellect (imagination, intelligence, curiosity, creativity) was the factor where no significant finding was made.
