gender similarities hypothesis
the notion that males and females are more psychologically alike than they are different. This directly contradicts the popular gender differences model stating that men and women differ enormously in cognitive ability, communication style, personality, social behavior, and dozens of other characteristics, and the similarities hypothesis has been criticized as lacking a theoretical basis (given that it is derived exclusively from meta-analysis) and as unnecessarily dismissive of contextually based gender differences. [proposed in 2005 by U.S. psychologist Janet Shibley Hyde (1948– )]
