Men overestimate how much their peers tolerate derogatory comments towards women and underestimate other men's willingness to step in to stop violence, a new paper says.
The issues paper will be released today, in support of White Ribbon Day, by the Auckland University-based Family Violence Clearinghouse, which is the national centre for collecting and distributing information about domestic violence.
Author and violence prevention researcher Garth Baker drew on international research to look at men's roles in stopping violence against women.
He found norms and social expectations around what it means to "be a man" have a powerful influence in shaping attitudes and behaviours.
"Firstly, men routinely overestimate other men's comfort with derogatory comments and behaviour towards women, and in the mistaken belief that they're in the minority, they keep quiet which may be in turn incorrectly interpreted as silent approval by others.
