The video spends a decent amount of time on the phenomena wherein men tend to feel the need to dominate discussions regardless of their actual qualifications. It cites one experiment wherein 16 women and 9 men had an introductory conversation on the issue. During this conversation there were 6 active speakers. 4 men speaking for a total of 9 minutes and 2 women who spoke for a total of 1 minute. These tendencies are mostly due to individuals desires to claim leadership of a group but are representative of larger issues having to do with hegemonic masculinity being largely incompatible with organizational activism. If you are interested, you can skip to the part that I mentioned by going here.
