A lot of recent research into altruism has led to some interesting findings. This new study is perhaps the most challenging of all in terms of our existing assumptions about individual philanthropy.
The Chinese team behind the latest study on the subject found that being stressed while witnessing injustice may push your brain towards altruism, according to their paper published journal PLOS Biology.
It takes more cognitive effort to punish others than it does to help them. Studies show that when witnessing an act of injustice while stressed, people tend to behave selflessly, preferring to help the victim than to punish the offender. This aligns with theories proposing that distinct brain networks drive intuitive, fast decisions and deliberate, slow decisions, but precisely how a bystander’s brain makes the trade-off between helping and punishing others in stressful situations is unclear.
To better understand the neural processes driving third-party intervention in the face of injustice, the researchers recruited 52 participants to complete a simulated third-party intervention task in an fMRI (functional magnetic resonance imaging) scanner, where they watched someone decide how to distribute an endowment of cash between themself and another character, who had to passively accept the proposal. The participant then decided whether to take money away from the first character or give money to the second. Roughly half of these participants submerged their hands in ice water for three minutes right before starting the task to induce stress.
Acute stress affected decision-making in extremely unfair situations, where the participant witnessed someone keep the vast majority of the cash they were supposed to split with someone else. The researchers observed higher dorsolateral prefrontal cortex (DLPFC) activation—a brain region typically linked to mentalizing and decision-making—when stressed participants chose to punish an offender. Computational modeling revealed that acute stress reduces bias towards punishment, raising the likelihood that someone will help a victim instead.
What the researchers say: “Our findings suggest that punishing others requires more deliberation, cognitive control, and reliance on calculations than helping a victim,” the lead author said. “These results align with a growing body of evidence suggesting that stressed individuals tend to act more cooperatively and generously, perhaps because people devote more of their cognitive resources towards deciding how to help the victim, rather than punishing the offender.”
“Acute stress shifts third-party intervention from punishing the perpetrator to helping the victim,” The researchers added.
So, what? This research aligns with what we know about how the human system, including the brain, works under stress.
More research is needed to illustrate the implications of this research—particularly in terms of the relationship between the perp and the victim. I suspect, for example, that altruism, even under stress, will be limited if the victim is either seen as an enemy or neutral and the perpetrator is an ally or perceptibly a member of their “tribe.”
Hence so many Americans see DT as a victim, and feel altruistic towards him, even when he clearly is not. They see themselves as part of his tribe.
