Some of us worry more than others. This varies from person to person, and most of us probably have an idea about where we fall along the spectrum. I can admit (and my family will gladly tell you) I touch down on the high end of this scale. Psychologists call it “neuroticism.”

“People who are high on this trait tend to feel negative emotions, like anxiety or sadness, more frequently and more strongly,” according to Sara Weston, Assistant Professor of Psychology at the University of Oregon. “They are also more likely to experience emotional instability, meaning they might jump from one emotion to the next more quickly or more often. Neuroticism's relationship to health can be quite complicated, especially in terms of understanding causality. For example, people who are high in neuroticism are more likely to receive diagnoses of hypertension, pulmonary disease, and cardiovascular disease (Weston, Hill, & Jackson, 2015). But is that because being high in neuroticism makes you less healthy? Or does being in worse health make you anxious or sad?”
 
“The truth is probably a bit of both,” she says. “For example, we know that people high in neuroticism are more likely to experience stress, which can in turn weaken our cardiovascular (Juster et al., 2015) and immune systems (Gouin, 2010). What's more, these same individuals are more likely to cope with stress with unhealthy habits, like smoking (Hakulinen et al., 2015). On the other hand, neuroticism is also associated with increased vigilance (Weston & Jackson, 2018). What this means is that people high in neuroticism report paying more attention to how their body feels and changes, suggesting this may help them catch signs of worse health sooner.” 
 

Are there cases in which being neurotic might improve health?
Or is it fair to consider this a "negative" trait?

Well for one thing, highly neurotic individuals “are more likely to seek medical help and receive diagnoses than people with similar health conditions but with lower anxiety,” according to Dr. Weston. So if your neuroticism leads you to seek medical treatment when appropriate, that could be a good thing. However, neurotic individuals also tend to have worse health overall—that association is clear. “But we don't know how much of that is due to chronic stress and unhealthy coping strategies and how much is just a perception of worse health.” Dr. Weston and colleagues are actively investigating this "healthy neuroticism" hypothesis, but so far evidence to support it has been hard to come by.
 
In the face of the current crisis there is a lot to think about — from understanding how exactly the virus spreads, to following the important advice of washing hands, not touching your face, and avoiding public gatherings (to name a few). We also know that merely thinking about the problem doesn’t help — and that unproductive worrying will just weigh you down. 
 
As for the neuroticism research, “It comes as a shock to approximately no person that our personalities can have an impact on our health,” Weston jokes … but “precisely identifying the ways in which our personalities have that impact can be quite difficult.” It sounds like some of the most exciting work is yet to come. As psychologists team up with health networks and other collaborators, and as modern forms of data access, collection, and analysis improve, our understanding of these questions continues to become clearer.

​In the meantime, we should probably all give ourselves a little break. Chronic stress certainly isn't part of the solution (at least not by the most recent CDC guides: https://www.cdc.gov.)

What We Found. 
The Decision Research team associated with the University of Oregon has been working to better understand these issues and set out to observe in real-time the process of deliberate ignorance in the face of global resettlement efforts. In one study, we began by asking a panel of Americans to consider whether or not they would like to help refugees in the Middle East by allowing them to relocate to communities across the U.S. The panel of 300 people was close to nationally-representative: mean age of 34 years, 60% male, 60% Caucasian, high school and college-educated, and an even mix of liberals and conservatives. While considering this relocation proposal, we provided our American participants with a menu of information items to consider—short, one-line descriptions similar to news headlines or press briefings. We presented 15 of these information items and allowed participants to choose which ones they would like to incorporate into their thinking about the issue; we said they could select only the most “important” ones. 
​
What we found was that participants who came into the study with attitudes that were already less-than-positive toward refugees were much more likely to hone in on information that might highlight the downsides of refugee settlement (e.g., an analysis of potential risks, crime statistics from other nations who’ve accepted migrants), and much less likely to pay attention to information about who these refugees were as people, what they could contribute, or where they would turn if denied refuge. On the contrary, participants who entered the study with neutral to positive views of refugees tended to select relatively equal amounts of security and humanitarian-related information. One thing this work tells us is that given the same menu of items, people seem to be consuming very different information diets. It also tells us that some percentage of Americans are simply turning a blind eye to the experiences of those in need, and using a cherry-picked base of information to promote exclusionist preferences.
 
Even with these results, it's important to acknowledge we still don’t know exactly why different people choose to click on different pieces of information. The process is complicated, and probably has multiple causes. We can’t pretend to know what’s going on inside everyone’s head. Maybe those who cherry pick security-related information are genuinely more susceptible to the emotional pull of fear-inducing stimuli. Alternatively, some people might ignore information on international issues but care deeply about helping those in their home communities. Political affiliations certainly play a role, too. These are open questions for future work to explore. 
 
Limitations notwithstanding, findings like these shed some light on why the current US administration has had little problem slashing foreign aid and rebuffing migrant support programs. In our democratic society, the attention of the public is what should and often does direct the attention of our leaders. But if considerable sections of the American public are as likely to ignore relevant information as some of the folks in our study, what kind of pressure are we putting on Washington to support humanitarian action? 
 
Fighting our own deliberate ignorance, and challenging others to do the same, is an important first step toward keeping humanitarian interests a part of this country’s foreign policy agenda. Even taking small actions like clicking on one article per day that we typically would ignore can help open us up to new perspectives and break the cycle of (sometimes nonconscious) information avoidance. ​​
