Moral psychology
Are 'logical' moral choices driven by coldness or calculation?
Open access · cc by · source: Europe PMC
People who make counterintuitive utilitarian moral choices often do so because of a reduced emotional aversion to harming others, rather than increased logical deliberation.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Deontological aversion to causing harm is heavily driven by emotional processing, such as empathic concern and brain activity in regions like the subgenual cingulate cortex, rather than purely cognitive calculation.
Evidence for the claim as stated.

sixteen participants
Sixteen healthy, right-handed subjects (9 female, mean age, 29.25, range, 21–41) participated in the study.
zero on the difficulty scale
At the end of each dilemma subjects were prompted to rate the difficulty of the dilemma using a Numerical Rating Scale ranging from 0 (=“not difficult at all”) to 100 (=“very difficult”).
Key findings
Individuals scoring higher in psychoticism made more utilitarian choices, and this pattern was associated with reduced activation in the subgenual cingulate cortex. The frequency of making these choices was positively correlated with psychoticism (r = 0.58) and with need for cognition (r = 0.51). However, only those with a high need for cognition showed a trend toward finding these difficult choices more mentally effortful.
Methodology
The researchers scanned sixteen healthy participants using functional magnetic resonance imaging while they evaluated various moral dilemmas. This included eight scenarios where avoiding harm was the intuitive choice, and ten scenarios where the utilitarian option was more intuitive. Participants rated how hard each decision was on a scale ranging from zero to one hundred, and their personality traits were assessed using standard questionnaires.
Limitations
Because the study utilized a very small sample of only sixteen individuals, the findings may not generalize well to larger populations and the imaging analysis has limited statistical power. The correlational design prevents researchers from concluding whether diminished brain activity causes utilitarian decisions or if both are caused by a third factor. Additionally, relying on self-reported difficulty ratings might not accurately reflect the actual cognitive processes occurring during decision-making.
