We could define paranoia as the belief that others intended to harm you. Most people have the occasional paranoid thought. Our minds are notorious for dysfunctional thinking—especially the kind we often fail to notice—but the recent surge in sincerely believed conspiracy theories has left many wondering what makes us more likely to believe paranoid conspiracies.
Science may have a partial answer. A Yale study published on June 9, 2020, shows that unexpected uncertainty “breeds paranoia.” Uncertainty has a well-documented tendency to affect the mind negatively. The report included a quote that I would be remiss not to include:
To understand the recent study, here’s what you should know. Everyone experiences paranoid thinking from time to time. How common these thoughts are among the general public may surprise you.
A group of seven thousand people answered a survey that hoped to capture a snapshot of each person’s experience with paranoia in the previous year. One-fifth of responders reported paranoid thoughts. One in twelve people believed someone had deliberately acted to hurt them in the last twelve months.
“Jumping to conclusions” is more common among those who naturally have more paranoid thinking.
Some of this may relate to us as “cognitive misers.” Our bodies prefer to do the least amount of work possible. Leaping to a simple judgment fits that bill. Complicated ideas require intensive study to understand, and who wants to do that? Not my brain and probably not yours either.
Difficulty with tasks that require someone to trust others was more common for people who tended toward paranoid thinking.
This led professionals to assume distrust caused paranoia. Now, they say–perhaps not.
The study, which includes appearances from rats on meth, tested how people responded to unexpected uncertainty. Let’s rename unexpected uncertainty, “surprise bad luck.”
The results say that depression and anxiety may be fertile ground for paranoia. Recalling that insomnia and a negative self-view are common among those suffering from paranoia, it seems depression or anxiety work like manure fertilizer does in the garden.
The pandemic and economic turmoil have many feeling depressed and anxious, meaning the ingredients for people to develop paranoia have come when people are meeting convincingly constructed conspiracies.
The rats’ brains respond as human brains on meth, not rationally. Under stress from surprise bad luck, our minds work in ways not dissimilar to the rats that were chronically consuming methamphetamine. Both humans and animals became hypervigilant, responding to a world they saw as full of more surprise bad luck.
A crisis leaves humans in a place where it is difficult to take in additional information. The refusal to accept any new evidence is a hallmark of paranoia. Surprise bad luck, like the pandemic, job loss, or economic depression, can make our minds act like the minds of our friends, the rats on meth.
Public health research has found that people in crisis often believe the first thing they hear and hold on to existing beliefs. The problem comes if the first thing we heard is a conspiracy theory, and we have paranoid thoughts compromising our ability to consider additional evidence even more. In short, surprise bad luck may stress us out enough to think like rats on meth.
