Signal A supplement that changed how subjects judged unfairness

Summary

This signal concerns research suggesting that gut microbes can influence decision-making. In the study a specific dietary supplement made people more sensitive to unfairness. Sitra cites a Helsingin Sanomat report from May 2024 on the finding. The result hints that what we eat may shape moral and economic judgements, not only physical health. It widens the idea of personalised nutrition toward effects on behaviour. Sitra uses it as a signal behind an imagined 2046 magazine recipe whose author claims a gut-friendly dish improved their children's empathy toward elderly housemates.
