Women are less likely to take risks. This may be a good thing though. Read this journal "Gender Differences in Risk Assessment: Why do Women Take
Fewer Risks than Men?"
http://journal.sjdm.org/jdm06016.pdf. If you don't want to, here's the abstract
"Across many real-world domains, men engage in more risky behaviors than do women. To examine some of the
beliefs and preferences that underlie this difference, 657 participants assessed their likelihood of engaging in various
risky activities relating to four different domains (gambling, health, recreation, and social), and reported their perceptions
of (1) probability of negative outcomes, (2) severity of potential negative outcomes, and (3) enjoyment expected from
the risky activities. Womens greater perceived likelihood of negative outcomes and lesser expectation of enjoyment
partially mediated their lower propensity toward risky choices in gambling, recreation, and health domains. Perceptions
of severity of potential outcomes was a partial mediator in the gambling and health domains. The genders did not differ
in their propensity towards taking social risks. A fifth domain of activities associated with high potential payoffs and
fixed minor costs was also assessed. In contrast to other domains, women reported being more likely to engage in
behaviors in this domain. This gender difference was partially mediated by womens more optimistic judgments of the
probability of good outcomes and of outcomes being more intensely positive."
Yeah. I know it's considered highly politically incorrect these days to differentiate gender influences in business, but the science of physiology, chemistry and psychology cannot be ignored. This risk has been recognised for many years, with even insurance policies now tailored towards the lower risk behvaiours associated with women (they pay less than men for health and life covers, for example).
This year's Nobel Prize for Economics was also awarded to the recognition of human propensity for risk taking in markets as the key reason for why market predictions and analysis (often based on rational models derived from AI).
Combining these two acknowledgments, it would make some sense to involve women in higher decision-making levels, not simply delegate them to communication roles (which, incidentally, they happen to be good at?).
