“It is not famine, not earthquakes, not microbes, not cancer, but man himself who is man’s greatest danger to man, for the simple reason that there is no adequate protection against psychic epidemics, which are infinitely more devastating than the worst of natural catastrophes.”
— Carl Gustav Jung, “The Undiscovered Self” (1957)

There’s a virus spreading faster than any we’ve seen before. It doesn’t attack the body, but the mind.
It’s called collective insanity, where whole groups of people begin to share the same irrational beliefs, emotions, and behaviors, drifting further and further from reality.

This kind of madness takes hold when critical thinking collapses and a free press is silenced or controlled. When truth becomes inconvenient, emotion and ideology take over. Falsehoods repeated often enough start to sound like truth, and soon, everyone is echoing the same slogans without stopping to ask, “Does this make sense?”

Collective insanity usually begins in times of deep economic and social uncertainty. The world feels unstable and frightening. During social unrest, war, economic turmoil, or disease, people crave certainty. They long for simple answers to complex problems, and for someone who promises to make everything right again.

That’s when a charismatic leader often appears, offering clear, emotionally charged explanations that seem to restore order. Dictators like Hitler, Mao, and Mussolini understood this perfectly. They demanded total obedience, convincing millions to surrender personal freedom, conscience, and judgment.

Strong emotions like anger, hate, and retribution spread quickly, almost like an infection of the soul.
We “catch” emotions from one another through something psychologists call emotional contagion. The more a narrative is repeated, the more real it begins to feel.

In authoritarian systems or cult-like movements, people learn to silence their doubts. To question is to risk punishment or exclusion, and so they conform. In time, they begin to believe the very lies they once only pretended to accept. (Experiments have shown this again and again, most famously by Solomon Asch, who proved that people will deny what they see if everyone around them disagrees.)

Collective insanity thrives where access to truth is restricted. It becomes especially dangerous when a small handful of billionaires control the flow of information or when social media algorithms feed us only what confirms our existing beliefs. These echo chambers create entire worlds of illusion, each reinforcing its own version of “truth.”

And once a society defines an enemy — witches, heretics, another race, or “the corrupt elite” — violence begins to feel justified, even noble. We see this pattern today in the growing attacks on politicians, judges, and journalists who dare to hold opposing views. The moral compass spins wildly when truth and empathy are lost.

History shows us that collective insanity inevitably ends, but often only after great suffering and when the truth finally comes out. The cult leader is exposed when there is no longer any denying of his sexual abuse. There is no longer any denying the authoritarian leader’s corruption, inept leadership and personal enrichment.
In Germany, the delusion collapsed when the war was lost, millions of lives had been lost, and the truth could no longer be denied. Putin’s Russia is possibly facing a similar scenario.
In South Africa, the Truth and Reconciliation Commission forced the nation to face the horrors of apartheid, allowing confession, grief, and healing to begin.

The path back to sanity always begins with truth-telling and with courage.
It takes brave souls, compassionate communities, and civic action groups to speak truth, even when it’s unpopular or dangerous. It takes emotional honesty and the willingness to face the grief, guilt, and fear without turning away.

When this is done collectively, something powerful happens. Healing begins.
We rediscover our shared humanity. Sanity and peace begin in the heart of each person who chooses truth, faith, and courage over fear.
