New research could explain why some people are more charitable than others
Altruistic people are said to be “kind hearted” – and new research published in the journal Scientific Reports shows that generous people really are more in touch with their own hearts.
The study, carried out at Anglia Ruskin University and Stockholm University, is the first to find a possible physiological reason why some people are more charitable than others.
Participants were asked to take part in a computer-based game that involved repeated choices to share sums of money between themselves and another participant that they hadn’t met.
Their choices affected how much real money they and the other participant received at the end of the study. The game has similarities to real-life charitable giving, in which recipients are not personally known to donors.
They also took part in a heartbeat detection task, which involved having their own heartbeat (ECG) recorded. The participants then listened, without feeling their pulse, to a series of sounds that were either in time or out of time with their heartbeats.
Those who were better at judging if the sounds were in time or not were better at detecting their internal body states. Performance on this task varied markedly between individuals.
The study found that participants’ monetary generosity directly increases with their ability to detect their own heartbeat – those who were on average 10% better at detecting their heartbeat gave away an additional £5 to the other participants.
