New research reveals that stress changes the way we deal with risk information.
The research sheds light on how stressful events, such as a global crisis, can influence how information and misinformation about health risks spreads in social networks, according to researchers at the University of Konstanz in Germany.
“The global coronavirus crisis, and the pandemic of misinformation that has spread in its wake, underscores the importance of understanding how people process and share information about health risks under stressful times,” said Dr. Wolfgang Gaissmaier, a professor in social psychology at the University of Konstanz and senior author on the study.
“Our results uncovered a complex web in which various strands of endocrine stress, subjective stress, risk perception, and the sharing of information are interwoven.”
The COVID-19 pandemic has demonstrated how risk information, such as about dangers to our health, can spread through social networks and influence people’s perception of the threat, with severe repercussions on public health efforts, according to the researchers.
However, whether stress influences this has never been studied, they noted.
“Since we are often under acute stress even in normal times and particularly so during the current health pandemic, it seems highly relevant not only to understand how sober minds process this kind of information and share it in their social networks, but also how stressed minds do,” said Dr. Jens Pruessner, a professor in clinical neuropsychology working at the Reichenau Centre of Psychiatry, which is also an academic teaching hospital of the University of Konstanz.
To do this, researchers had participants read articles about a controversial chemical substance, then report their risk perception of the substance before and after reading the articles. They also were asked to say what information they would pass on to others, according to the researchers.
Just prior to this task, half of the group was exposed to acute social stress, which involved public speaking and mental arithmetic in front of an audience, while the other half completed a control task.
The results showed that experiencing a stressful event drastically changes how we process and share risk information, according to the study’s findings.
Stressed participants were less influenced by the articles and chose to share concerning information to a significantly smaller degree.
“Notably, this dampened amplification of risk was a direct function of elevated cortisol levels indicative of an endocrine-level stress response,” the researchers reported.
In contrast, participants who reported subjective feelings of stress showed higher concern and more alarming risk communication, the study discovered.
“On the one hand, the endocrine stress reaction may thus contribute to underestimating risks when risk information is exchanged in social contexts, whereas feeling stressed may contribute to overestimating risks, and both effects can be harmful,” said Dr. Nathalie Popovic, first author on the study and a former graduate student at the University of Konstanz.
“Underestimating risks can increase incautious actions, such as risky driving or practicing unsafe sex. Overestimating risks can lead to unnecessary anxieties and dangerous behaviors, such as not getting vaccinated.”
By revealing the different effects of stress on the social dynamics of risk perception, the study shines light on the relevance of such work not only from an individual, but also from a policy perspective, according to the researchers.
“Coming back to the ongoing COVID-19 pandemic, it highlights that we do not only need to understand its virology and epidemiology, but also the psychological mechanisms that determine how we feel and think about the virus, and how we spread those feelings and thoughts in our social networks,” Gaissmaier said.
The study was published in the journal Scientific Reports.
