Why Highly Sensitive People Actually Respond More To Social Cues Than Physical Environments

The Misconception of the Highly Sensitive Person: It’s Not About the Physical World

The term environmental sensitivity—a personality trait often used to describe individuals who feel experiences more deeply than others—may be a misnomer. New research from Washington State University suggests that the trait is less about a heightened reaction to physical surroundings and more about an acute attunement to social cues and perceived interpersonal threats.

The study, published in the Journal of Environmental Psychology, challenges the long-held assumption that “highly sensitive” people are inherently more reactive to all external stimuli, including ambient noise, temperature fluctuations, or unpleasant odors. Instead, the findings indicate that these individuals are primarily influenced by the social climate of their environment.

“For people who do identify as highly sensitive, it’s actually kind of nice to know that you’re not necessarily going to have a stronger emotional response to all parts of your environment,” says Kim Meidenbauer, an assistant professor of psychology at WSU and lead author of the study. “It seems like it’s more about social environments than the physical environment.”

To investigate whether this sensitivity extended to mundane physical settings, researchers analyzed data from over 3,800 surveys completed by Chicago residents. Participants utilized a smartphone application to document their emotional states while rating various outdoor conditions in parks and neighborhoods. The results revealed a clear divide: while highly sensitive individuals reported more intense emotional responses to signs of disorder, perceived safety risks, or positive social interactions, they showed no greater emotional reactivity to physical factors such as air quality, noise levels, or temperature than their less sensitive counterparts.

This discovery prompts a reevaluation of how psychologists classify this personality trait. For years, environmental sensitivity has been recognized as a disposition linked to both genetics—with nearly half of the variance in sensitivity attributed to inherited factors in studies of twins—and life experience. However, the current tools used to measure this trait may be inadvertently capturing a person’s social and emotional vigilance rather than a general heightened physiological reactivity to the physical world.

While this research clarifies the nature of the trait, Meidenbauer emphasizes that it does not preclude the possibility of stronger reactions under extreme or hazardous conditions, such as severe pollution or dangerous heat waves. Her team is currently expanding their research to explore how individual preferences and other personality variables might account for the varied ways people navigate extreme climates.

Ultimately, the study suggests that the “highly sensitive” label might be misleading. Rather than experiencing every aspect of the world with amplified intensity, these individuals may simply be more responsive to the human-centric elements of their surroundings—the social threads that dictate whether a space feels inherently welcoming or threatening.
