Moral Cognition and Visual Imagery: A Brain Stimulation Study
Moral Dilemmas
Deontological vs Utilitarian Judgments
Limitations in the field
"It’s wartime. You and your fellow
villagers are hiding from nearby enemy soldiers in a
basement. Your baby starts to cry, and you cover your
baby’s mouth to block the sound.

If you remove your
hand, your baby will cry loudly, and the soldiers will
hear. They will find you, your baby, and the others, and
they will kill all of you. If you do not remove your
hand, your baby will smother to death."

Is it morally
acceptable to smother your baby to death in order to
save yourself and the other villagers?
