Story summary

University of Zurich researchers used electrical stimulation on brain regions linked to decision-making and altruism in 44 participants choosing between a larger money amount and sharing with an anonymous partner.
The stimulation altered decision-making, increasing the likelihood of sharing even when it caused personal financial loss.
