Hypergender

Given the research results indicating that hypermasculine men and hyperfeminine women appear to share similar attitudes and the overlap in content of several of the HMI and HFS items, it is plausible that acceptance of hypergender ideologies (i.e., hypertraditionality, Byrne & Schulte, 1990; Smith, 1989; Smith et al., 1995) represents a unifying constellation of attitudes that encompasses both. That is, hypermasculinity and hyperfemininity may represent gender-typed manifestations of a broader constellation of attitudes, which we call hypergender ideologies.

[…] Hypergender ideology, beliefs that heterosexual relations were adversarial and rape myth acceptance formed a ‘block’ of interrelated attitudes among participants, […] (Loh et al., 2005, p.1334).
