Judith Rich Harris

**Judith Rich Harris** (February 10, 1938 &ndash; December 29, 2018) researched psychology.  She was an independent researcher, and not a university professor.  Her most famous book is *The Nurture Assumption*.  Children often act like their parents act.  Some psychologists thought this was because of the way that parents raised their children.  Harris argues that (some or all of) this similarity is due to genetics.  Otherwise, parents are not the most important factor in child development.  This book argues that peers are more important.   Harris argues that children are socialized by peers.

### No Two Alike
Harris also wrote *No Two Alike: Human Nature and Human Individuality*.  It was published in February 2006. Harris attempts to explain why people are so different in personality, even identical twins who grow up in the same home.

## Opinions of her work 
George A. Miller was chair of the Department of Psychology which formally dismissed Harris from the PhD program at Harvard, 1960, on the grounds that her 'originality and independence' did not live up to Harvard's standards.

Later, in 1994, she developed a theory of child development, which focussed on the peer group rather than the family. This formed the basis for a 1995 article in the *Psychological Review* for which she received the American Psychological Association's George A. Miller Award for an Outstanding Recent Article in General Psychology.

## Death
Harris suffered from a chronic autoimmune disorder, diagnosed as a combination of lupus and multiple sclerosis. She died on December 30, 2018 at the age of 80.
