Leonard Sax

Leonard Sax is an American psychologist and a practicing family physician. He is best known as the author of three books for parents: Boys Adrift, Girls on the Edge, and Why Gender Matters. According to his web site, he is currently employed as a physician at a healthcare facility in Chester County Pennsylvania, where he also resides.

Sax's views on gender differences have been controversial.

Sax graduated Phi Beta Kappa from the Massachusetts Institute of Technology (MIT) in 1980 with a bachelor's degree in biology. He completed the combined M.D.-Ph.D. program at the University of Pennsylvania in 1986. His Ph.D. is in psychology. He completed the 3-year residency in family practice at Lancaster General Hospital in 1989. In 1990, he founded Poolesville Family Practice, a primary care practice in Montgomery County, Maryland. He began an extended sabbatical from medical practice in June 2008. In December 2013, he returned to full-time clinical practice as an employee of Lancaster General Health.

Sax's work has attracted most attention, positive and negative, for his views on gender. Broadly, he supports the notion of innate differences between the sexes, and advocates parenting children differently based on their gender. A March 7, 2005, cover story for Time Magazine included this statement:

"Until recently, there have been two groups of people: those who argue sex differences are innate and should be embraced and those who insist that they are learned and should be eliminated by changing the environment. Sax is one of the few in the middle -- convinced that boys and girls are innately different and that we must change the environment so differences don't become limitations."

On his web site, Sax says that he wrote Boys Adrift and Girls on the Edge because he is concerned about

"a growing proportion of girls who are anxious, depressed, and tired; girls who can tell you a great deal about what they do but not so much about who they are. Likewise, we find a growing proportion of boys who are disengaged not only from school but from the real world. Those boys are comfortable in the virtual world, where they play their online video games, and/or surf the net for photographs of girls."
