Numerous studies show that people are more willing to inflict harm on men than women, more willing to kill men than women, and treat harm against men as less serious than harm against women. Women treat men as less valuable to a greater degree than men, and women who identify as feminists may be even more sexist than women on average. These attitudes are promoted by women to their children, but not by men.

Significant examples include the "Trolley Problem" where subjects are 7 times more likely to throw a man off a bridge to save others than a woman, and a variant of the Milgram experiment, where participants subjected men to greater electric shocks than women.

There is also evidence that suggests male disposability is a result of social conditioning, not instinct. The effect is larger if the subject is being watched than not, and people report it is more socially acceptable to harm men than women.
