Global trends of the MIT study highlight that, overall, people prefer to save the lives of humans over other animals, prioritize the lives of many rather than few, and spare the lives of young rather than old. Men are slightly more likely to spare the lives of women, and religious affiliates are slightly more likely to prioritize human life. The lives of criminals were prioritized more than cats, but the lives of dogs were prioritized more than the lives of criminals. The lives of homeless were spared more than the elderly, but the lives of homeless were spared less often than the obese.
