What’s the theory behind conspiracy theories?

Here’s a brain teaser for you: How does one connect the outbreak of a highly contagious and viral infection to the destruction of wireless network posts?

If you don’t know the answer to this, then you may be pleased to know that you have not yet fallen into the pit hole of conspiracy theories—or at least not ones related to 5G towers and the coronavirus. We use this as an example of conspiracy theories as the idea that 5G waves are linked to COVID-19 has recently gone viral (pun sort of intended) on many social media sites.

This conspiracy theory is based around the general claim that 5G was created to deliberately spread the virus, despite being untrue.[1] Much like other conspiracy theories out there, these tales can have detrimental consequences on individuals and communities. Some of these include caring less about one’s health,[2] the people around them[3] or even the environment.[4] Despite all this, how do these bizarre theories and explanations become so popular?

We posit that they gain traction because they promise to satisfy important psychological needs that everyone has. This causes the belief in conspiracy theories to become deeply rooted in the individual, as well as making it difficult to shift their opinions on it.

What makes a conspiracy theory?

All conspiracy theories follow a similar template. First, they all suggest that a small group of elite individuals are colluding away from public scrutiny to push a private agenda.[5] The 5G coronavirus theory dividedly points to governments, Bill Gates or the Illuminati as the ones responsible.

Second, conspiracy theories are all baseless.[5] In our example, we can find scientific evidence that 5G’s high-frequency waves are beneath the wavelength that can damage human cells.[1,6]

So how is it that these “theories” take root in people’s minds when they rely on exaggerated claims and little hard evidence in their favour? A recent study has identified a triad of psychological needs (epistemic, existential, and social) that conspiracy theories cover like a band-aid to a mental wound.[5] 

1. Epistemic Needs

Epistemic needs are basically the desire for knowledge. We all inherently want to be able to explain the events around us in order to have an accurate understanding of how the world works.[5]  Because we don’t like being in a state of uncertainty, we tend to settle for the information that is readily available and makes some form of sense. However, the available data often is incomplete or under constant change, which makes for “plot holes” in the narrative around an event. Conspiracy theories typically cover such gaps and provide us with cognitive closure.[5]

2. Existential Needs

Conspiracy theories also serve our need to feel safe, secure, and in control of our environment.[5,7,8] When we feel lost, we try to grasp onto something that provides us with security, which subdues the feeling of powerlessness. The 5G coronavirus theory, for example, clearly fuels this need: people are attacking 5G masts because they (erroneously) believe this will reduce their chances of contracting the virus.

This behaviour is called action bias, and it is the belief that value only comes from action. This bias causes some to execute poorly-planned actions to assert control over their circumstances, rather than practising restraint even if it is reasonable to do so.

3. Social Needs

Conspiracy theories are also adopted to uplift one’s identity and to project a positive image of themselves.[8] If our self-perception is threatened by external events, we are more likely to believe in a conspiracy theory if it “saves face” for us.[9] This often results in pitting a group against another, which leads to conspiracists often framing social issues as a direct confrontation between groups. We call this phenomenon the “Us vs. Them” scenario.[10] 

The social need makes it seem likely that conspiracy theories are particularly appealing to people who find themselves or their groups as targets of discrimination or disadvantage. Thus, we will consider individual characteristics next. 

Psychological Traits

Those who have experienced adverse life circumstances or chronic health issues are more likely to develop negative psychological symptoms such as anxiety, delusional thinking, or paranoia.[11,12] People who have suffered trauma also tend to look for links and patterns between concepts as a way to recover control and security. These, in turn, can make a person hypervigilant, influencing their belief in conspiracy theories.[13,14]

The symptoms we mentioned can also relate to an underlying feeling of distrust in field experts, identified by persistent thoughts such as “the authorities are hiding something,” or “the government is out to get us.”[14,15] These thoughts may then trigger conspiratorial beliefs as a cognitive defence mechanism.[16] In simpler terms, belief in these theories is a way of dealing with situations that induce anxiety and uncertainty. We can also see this belief as a consequential drive to reconcile worrying thoughts with information that is readily available.

And why, you ask, is all this information on conspiracy theories so accessible?

The answer is simple: conspiracy theories have been found to spread faster than scientific articles on social media.[17] The exact reason why that’s the case is not entirely understood, but it (kind of) makes sense. After all, many conspiracy theories are really creative and interesting. Some might even say they’re more interesting than statistics and science. And once you share a post about angry mobs destroying 5G masts just for laughs, social media algorithms step in and give you more of that content.

Because of this, conspiracy theories seem to rule the Internet. Over time, people’s beliefs in them become resistant to change due to the seemingly endless supply of content on them (thanks, Facebook algorithms!). We humans also tend to favour things that we are more frequently exposed to and thus more familiar with. This is called the mere-exposure effect.[18]

How do we tackle conspiracy theories? 

There are two main ways in which we can approach a conspiracy theory: by refuting it or ignoring it.[19] Both approaches pose some issues. 

On one hand, refuting the theory can in fact strengthen it, suggesting that those who try to debunk the theory are actually a part of the conspiracy.[5] Trying to disprove them by harsh criticism would also be just as ineffective,[19] and people may start to find new ways of backing up their beliefs. As conspiracy theories take roots in a person’s need for self-fulfilment, an attack to the narrative is taken as a personal affront. Hence, conspiracists end up defending their beliefs more strongly in the face of criticism.

On the other hand, ignoring a conspiracy theory can be perceived as a confirmation thereof—even more so if the theory isn’t addressed by those in positions of power. This just tells the public that the authorities simply can’t provide any logical explanations to disprove the theory.

Therefore, the best way to address conspiracy theories is communication with an open mind, which is the first step to eliminating conspiratorial beliefs. It also helps if the conspiracist is presented with the rational shortcomings of the theory from someone they perceive as intelligent and competent.[20]


Bottom line is: conspiracy theories are attractive because they target core psychological needs we’re seldom aware of. Epistemic, existential, and social needs are generally the same for everyone, but personality traits and life circumstances make some people more prone to fall in the conspiratorial rabbit hole. The Internet and social media have also made it ridiculously easy for misinformation to spread around and, because conspiracy theories are very entertaining, they end up overtaking scientific facts in the spotlight. 

Conspiracy theories are not a recent event and they will always be present in the conversation. If you know someone who tends to bring them up, don’t despair. Talk to them, acknowledge their points of view, address the facts non-judgmentally and compromise in that, maybe, the truth is not what it appears to be.
