Can Isolation Make Conspiracy Theories More Believable?

Ever feel like the world just doesn't get you? Loneliness can create a hunger for connection, sometimes leading people down the rabbit hole of conspiracy theories.  This article explores ten reasons why isolation can make these stories so alluring, offering insights into the psychology of belief and belonging.

Feeling isolated as a teenager can have lasting impacts, increasing the likelihood of believing conspiracy theories as an adult. A study by Nature’s Communication spanning 28 years, with participants initially aged 12–20, supports this finding. This relationship held true even after considering the influence of depression and anxiety. The study gauged loneliness with statements like "No one really knows me well."

Researchers have found a link between social exclusion and believing in conspiracy theories. When people are left out, they search for reasons, sometimes finding them in these stories.  During an experiment by Princeton University, students wrote personal essays and were told their peers would evaluate them for inclusion in a collaborative task. Turned out, students who were thought to be excluded students were more likely to find meaning in the unusual.

Online conspiracy groups offer instant camaraderie and validation, which can be especially appealing to lonely people. This ready-made sense of belonging can also be powerful, making it hard to leave even as real-world relationships suffer. The support within these groups then becomes a substitute for outside connections. In fact, leaving can feel isolating as it reinforces the perceived need to stay.

During 2020, conspiracy theories about COVID-19 exploded online. The pandemic’s uncertainty and isolation created fertile ground for misinformation. Some theories even falsely claimed that vaccines were dangerous or part of a larger plot. Despite evidence proving them wrong, these stories spread like wildfire, particularly the false claim of vaccine-induced mass casualties.

What happens when society builds walls instead of bridges? Inequality in schools and workplaces often leaves people on the outside looking in. That distance isn’t just economic—it’s emotional. And when loneliness grows, conspiracy theories whisper louder. Perhaps fairness, especially in education, might be the quiet cure we overlook.

People sometimes use beliefs to cope with difficult feelings, a process called motivated reasoning. For lonely individuals, conspiracy theories can offer that sense of comfort. They explain isolation as something external, protecting one's ego from self-blame. In fact, this makes tough feelings easier to handle.

Social circles provide important feedback, helping us refine our understanding of the world.  Isolated individuals often lack such corrective influence. Without these reality checks, conspiracy theories can take root and solidify. Online echo chambers further exacerbate this by creating an illusion of consensus, and mistaken beliefs thrive in these environments.

When people feel isolated, they are more likely to have PLEs. Such experiences, like unusual perceptions, make conspiracy theories seem plausible. Mediation analysis also demonstrates that PLEs are the primary connection between loneliness and conspiracy theory endorsement.

Surprisingly, having lots of friends doesn't make you immune to conspiracy theories. In fact, perceived loneliness, and not the actual size of your social network, fuels belief in conspiracies during the pandemic. The subjective feeling of isolation mattered more than objective social connections. Even within a large family, someone might feel disconnected and thus more susceptible.

Is loneliness really to blame for believing in conspiracies? A new study published in the Journal of Individual Differences suggests it’s complicated. Researchers found no direct relationship between loneliness and conspiracy thinking when considering other influences. This result differs from previous findings, particularly from Norway. The study's "consistent null effect" was also unexpected, prompting a focus on different forms of isolation since loneliness alone may not be the key.
