Harvard Business Review has been conducting a survey every 20 years since 1965 to gauge the perception of women in executive roles. The first survey in 1965 showed that a large portion of men viewed women in management roles negatively, seeing the executive suite as an inappropriate place for them. Over the years, attitudes have improved, but a gap has surfaced in how men and women view opportunities, standards, and evaluation in the workplace. A recent survey of 193 senior executives in the US found that men and women have different views on whether women are judged more critically in executive roles, with 35% of men and 90% of women believing this to be true. The survey also found that 83% of women believe they need to be more exceptional than men to succeed, compared to 28% of men. Women are also more likely to believe that promotion criteria are not equal across genders and that their company is not a meritocracy. The study confirmed the double standard that men are promoted based on their potential, while women need to have a pristine record to be considered. The perception gap between men and women has widened in recent years, despite overall improvements in attitudes since 1965. The findings are consistent with other studies, such as the "Women in the Workplace" study, which found that women are underrepresented at every level of the corporate pipeline and face higher rates of burnout. The researchers suggest that the "prove-it again" bias, which requires women and people of color to provide more evidence of competence, has intensified and is a major obstacle to achieving equality in the workplace.
