‘When making moral judgements, we rely on our ability to make inferences about the beliefs and intentions of others. With this so-called “theory of mind“, we can meaningfully interpret their behaviour, and decide whether it is right or wrong. The legal system also places great emphasis on one’s intentions: a “guilty act” only produces criminal liability when it is proven to have been performed in combination with a “guilty mind”, and this, too, depends on the ability to make reasoned moral judgements.

MIT researchers now show that this moral compass can be very easily skewed<. In a new study published in the Proceedings of the National Academy of Sciences, they report that magnetic pulses which disrupt activity in a specific region of the brain’s right hemisphere can interfere with the ability to make certain types of moral judgements, so that hypothetical situations involving attempted harm are perceived to be less morally forbidden and more permissable.’ (Neurophilosophy)
