The Lucifer Effect
There are seven social processes that grease “the slippery slope of evil”:[19]
- Mindlessly taking the first small step
- Dehumanization of others
- De-individuation of self (anonymity)
- Diffusion of personal responsibility
- Blind obedience to authority
- Uncritical conformity to group norms
- Passive tolerance of evil through inaction or indifference
