Summary & Review

In "Why Him? Why Her?" Helen Fisher explores the concept of how our personality traits influence who we are attracted to and ultimately fall in love with. Fisher asserts that everyone has a primary personality type, a belief backed by scientists suggesting that nearly 50% of variations in human temperament are genetically based. The four primary types, according to Fisher, are the Explorer, Builder, Director, and Negotiator. Understanding these personality types, and our leanings towards them, can greatly influence our search for long-lasting love.
