COVID-19 could nudge minds and societies towards authoritarianism

It is a little-known fact that humans have not one but two immune systems. The first, the biophysical immune system the one we’ve all heard much about responds to infections as they enter the body, detecting and eliminating intruders such as the coronavirus.

The second is the behavioural immune system, which adapts our behaviour to preemptively avoid potentially infectious people, places and things. The behavioural immune system is the first line of defence against infectious disease. It prompts people to socially conform with known traditions and to avoid foreign, dissimilar and potentially infectious groups.
In a recently published study, my colleagues and I at the University of Cambridge examined the impact of the behavioural immune system on our attitudes towards obedience and authority. We found that high rates of infectious diseases and the disease-avoidance they promote may fundamentally shape political opinions and social institutions.

Infection drives authoritarianism

We collected data from over 250,000 people across 47 countries and looked at the relationship between the (pre-COVID) infection risk where they lived and their authoritarian attitudes the degree to which they endorsed conformity and obedience to authority.

We were curious as to whether high risk of infection would activate the behavioural immune system in ways that promoted authoritarian beliefs. We made sure to measure authoritarianism in a politically neutral way, to avoid our results reflecting people’s religious beliefs or commitments to certain political parties.

We found a clear relationship between people’s authoritarian attitudes and their region’s levels of infectious diseases: areas with a higher prevalence of infectious diseases had more authoritarian citizens. Additionally, areas with high infection rates tended to vote conservatively and were governed by more authoritarian laws laws that are imposed on some members of society but not all.
Examples of authoritarian laws include legal restrictions surrounding LGBT civil liberties or extreme criminal punishment. Infection rates were specifically related to these vertical hierarchical laws, and not to horizontal laws that affect all citizens equally suggesting rates of infectious disease uniquely affect people’s preferences for hierarchical power structures.

Strikingly, the pattern of results was consistent when comparing the 47 countries as well as US states and US metropolitan regions and cities. These effects persisted even after accounting for regional demographic variables such as educational attainment, wealth and inequalities, suggesting direct and significant relationships between infectious diseases and authoritarian beliefs and behaviours.

We further discovered that the relationship between infection rates and authoritarianism was specific to infections that can be acquired from other humans, such as measles or cholera. The effect was absent for infectious diseases that can only be acquired from nonhuman species, such as rabies or Lyme disease.
These results support the idea that there is a social and behavioural mechanism connecting infection risk and authoritarianism. A high prevalence of human-to-human infections appears to lead to conformist and obedient social arrangements that potentially reduce the risk of people being infected by those who do not conform or resemble the majority. Social diseases like COVID-19 may therefore sculpt social ideologies and institutions.

How to overcome COVID’s influence

In the COVID-19 era, we have all been living with overactivated behavioural immune systems. We have changed how we socialise and relate to other people; who we allow to enter our countries; and how we calculate the balance between personal freedom and collective safety.

What does this mean for our political futures? Will the fear of COVID-19 push us towards living in more authoritarian societies? How do we restore a psychological balance and a preference for political anti-authoritarianism without endangering ourselves and others?
The first inevitable step is to decrease real infection risks. Without a reduction in real health risks through effective vaccination programmes and health policies, our all-too-human bodies will naturally tend towards defensiveness, conformity and an aversion to threat.

Indeed, COVID-19 has brought about a global wave of authoritarian policies that have justified the tightening of national borders and limitations of everyday rights. In our study, we found that even historical infection rates from decades earlier predict what citizens believe, who they vote for and how they are governed today. Pandemics may have long-lasting and profound ramifications for politics.

However, while our instincts to avoid infection are inbuilt the behavioural immune system has been documented in species as varied as mice, frogs and chimpanzees humans are endowed with magnificent mental capacities to overcome biases and flexibly adapt to change. If it is our highly evolved imagination that facilitates the behavioural immune system, then it is also our rich and compassionate imagination that can pull us out of its toxic side-effects.
Safe contact with those who we are instructed to avoid even imaginary, intellectual or virtual contact, through film or literature or news or friends is a powerful antidote to the xenophobia that can emerge when we fear infection. These forms of nonphysical touch can remind us of all we have in common and all we can lose if we shun contact and care.

Perhaps the way forward lies in adopting anti-authoritarian stances that champion openness, inclusion and scientific reasoning rather than mythical, ideological or conspiratorial thinking. Overcoming the COVID-19 pandemic and the contagious divisions within our politics may thus be intertwined tasks. The health of society the collective body politic requires the health and resilience of our bodies and minds. Immunity is fundamentally political.
