As part of the women in leadership programme, MWA champions evidence and research to demonstrate the downsides of these norms. As stated by MWA, unconscious bias in the way that we see and evaluate women creates invisible barriers to women’s leadership (MWA 2013). Related to the social norms described previously, unconscious bias often manifests in the behaviour of senior leaders and decision-makers, whose negative attitudes may hinder the progression of women into senior roles.
