Mattias Desmet and Mike Yeadon are two great men who think very deeply about things, and I have the much respect for their passion and insights into human behaviour and mental health.

And their desire to understand why people behave in a certain way.

The most dangerous madness of all is the madness of the group.

Friedrich Nietzsche
‘The Triumph of Death’, by Pieter Bruegel the Younger (1626)

Mattias Desmet

Mattias is a Professor of Clinical Psychology at Ghent University in Belgium, focusing on mass crowd formation, totalitarianism, mass hypnosis, indoctrination and, basically, how the human mind works.

Mass formation is a phenomenon that occurs when a large group of people develop irrational beliefs or engage in collective behaviour that defies logic or reason. 

Mass hysteria is a condition in which a large group of people exhibit the same state of violent mental agitation.


It’s like a contagious mindset that spreads within a community, leading individuals to adopt the same thoughts, behaviours, or beliefs.

It’s as if masses of people are hypnotised.

And it really does look that way.

Mike Yeadon

Meanwhile, Mike is a retired British pharmacologist who served as the chief scientist and vice-president of the Allergy & Respiratory Research Division of Pfizer, and is the co-founder and former CEO of the biotechnology company Ziarco.

He left Pfizer in 2011 and has spoken out against the entire Covid narrative.

Let’s be clear

Included in all of that was a type of collective craziness. A type of crowd madness. Millions of people acting like mindless zombies.

Or, as Mattias describes it, mass formation.

It’s a psychological state in which a large group of people all start believing in the same idea. This happens when four things come together:

  • people feel alone and not connected,
  • everybody is anxious and worried,
  • there’s a belief that makes them feel better,
  • there’s a strong leader who supports the said belief.

Which means that the sheep people in this state are likely to accept – or believe something – without thinking critically.

Be the sheep that doesn't wear a mask

The madness of crowds is an integral part of history, always repeating itself because human nature remains the same.


As silver linings go, there has also been a mass awakening.

Here is my conversation with both Mattias and Mike.

In individuals, insanity is rare; but in groups, parties, nations, and epochs, it is the rule.

Friedrich Nietzsche
