"If You Understand How the Brain Works, You Can Reach Anyone"

A Biological Approach Helen Fisher, the biological anthropologist whose research informed Deloitte's work on team chemistry, derives her personality assessment from brain science. In searching for an answer to what makes an individual fall in love with one person and not another, she found that four biological systems--dopamine/norepinephrine, serotonin, testosterone, and estrogen/oxytocin--are each linked to a particular suite of personality traits. Fisher explains the science behind her work, talks about how to identify and adjust productively to others' personality styles, and considers whether personality screening can and should inform management decisions. The Tests That Shaped the Industry Over the past 100 years, three tests--the Myers-Briggs Type Indicator, the Five-Factor Model, and StrengthsFinder--have had an outsize impact on the theory and practice of personality screening.
