When it comes to vaccines - why are people talking about 'Absurd causality' ?

Implausible side effects and contaminants (e.g., autism or active viruses)

Some people will reject vaccinations based on unwarranted beliefs.  For example, the claim that the body has a ‘natural healing potential’ or that ‘natural’ is always better. This may lead people to believe that suffering a ‘natural’ disease in order to achieve subsequent immunity is preferable to being vaccinated, which is the exact opposite of the actual risks.

Many adherents of ‘alternative medicine’ hold unwarranted beliefs and are sceptical of vaccinations.

Research has shown that these unwarranted beliefs are particularly shaped by ‘cognitive variables’, a psychological term which describes the ways in which people process information.

It is these cognitive variables that separate unwarranted beliefs from conspiracist beliefs, which is primarily influenced by perceived threat and emotional variables.

These cognitive variables include:

  • An intuitive cognitive style; accepting ‘gut feeling’ as a better guide to truth than evidence.
  • Ontological confusions; people may struggle to differentiate metaphorical from factual statements, for example taking statements that ‘trees can sense the wind’ or ‘old furniture knows things about the past’ literally.
  • Being receptive to pseudo-profound statements, for example considering a statement such as ‘wholeness quiets infinite phenomena’ to be profound.
  • Susceptibility to causal illusions; believing that one event affects another when in fact there is no causal relationship, for example that your favourite football team won a game because everybody watching it from home was wearing the team jersey.

This theme encapsulates beliefs that vaccinations cause severe harm or are ineffective. Critically, these arguments are based on implausible beliefs and perceived associations that are not backed up by scientific evidence.

Is there any truth in it?

It is normal to have questions and doubts about medical treatments and how they might affect us. The world can sometimes feel like a dangerous place, and we don’t fully know why some conditions occur. It is understandable to want to know what caused a problem so we can try to avoid it or solve it.

What could I say to someone fixed on this belief?

Dialogue between patients and healthcare professionals is most productive if it is guided by empathy, and an opportunity for the patient to affirm the reasons underlying their attitudes and to express understanding for that. That’s why it is important to understand the attitude roots behind people’s overt opinions. To affirm a person’s underlying attitude root does not mean we need to agree with the specifics of their argument. For example, we can acknowledge that:

It is normal to have questions and doubts about medical treatments and how they might affect us. The world can sometimes feel like a dangerous place, and we don’t fully know why some conditions occur. It is understandable to want to know what caused a problem so we can try to avoid it or solve it.



Having set the stage through this (partial) affirmation, we can then proceed to correct the patient’s particular misconception.

Fear and uncertainty can lead us to see connections that do not exist.

Those with vested interests in finding false links often go to great lengths to publicise false information. For example, in 1998 Andrew Wakefield, who was paid by personal injury lawyers, published an article that falsely claimed a link between MMR and autism. The article was retracted after his scientific misconduct was revealed, and extensive research has found that vaccines do not cause autism.

We need to distinguish between events that simply occur at random close together, and those that are actually linked.

Not everything that happens just after we have a vaccination is caused by the vaccine.

Sometimes unrelated medical conditions occur close to a vaccination, but so do other accidents. If we had an accident in the hospital carpark after getting a vaccine, that would be tragic, but it cannot be blamed on the vaccine.
