What have anthropologists discovered about different cultures' definitions of masculinity and femininity?

The answer is "there is far more variability in definitions of masculinity than any biologist would have predicted."

A masculine society has characteristics that are ordered as male, for example, quality, strength, self-assuredness, and pretention. Feminine society is generally thought of as having customary qualities, for example, being strong, mindful, and relationship arranged. Each sort of society will react in an unexpected way, as a crowd of people in the business world. A communicator needs to fathom the diverse societies and tailor his/her message in either a masculine or feminine route contingent on the group of onlookers.
