This theory is a new one for me. Perhaps not as compelling as Victor Frankl’s insights about our search for meaning, but sure seems relevant for our current times.

From Google:

Dietrich Bonhoeffer’s theory of stupidity is a famous psychological and sociological observation written in 1943 from a Nazi prison cell in his text "After Ten Years" (found in Letters and Papers from Prison). Bonhoeffer tried to understand how an entire educated nation like Germany could succumb to the moral catastrophe of Nazism.

Core Arguments of the Theory

• Not an intellectual defect, but a moral one: Bonhoeffer argued that stupidity is not about having a low IQ. Exceptionally smart and educated people can be "stupid," while dull-witted people may not be. It is a human and moral failure—a surrender of critical thinking.

• More dangerous than malice (evil): You can protest against, expose, or use force to stop an evil person, and evil eventually leaves a sense of unease or self-subversion. Against stupidity, however, people and society are defenseless. Reasons fall on deaf ears, and contradictory facts are ignored or dismissed as incidental.

• Self-satisfied and aggressive: The stupid person is utterly self-satisfied. When pushed with irrefutable facts, they easily become irritated, feel threatened, and go on the attack. Persuading them with logic is both senseless and dangerous.

• A sociological phenomenon, not an isolated one: Stupidity is rarely seen in people who are isolated or in solitude; it surges when people gather in groups, crowds, or under the influence of powerful political or religious authorities. Power "infests" people, causing them to surrender their inner independence and become unthinking mouthpieces for slogans and ideologies.

• Enablers of evil: Evil people (the "puppet masters") often lack the direct power to dominate on their own, so they rely on a mass of compliant, unthinking stupid people to do their dirty work.

The Key Elements of Stupidity

Scholars summarizing Bonhoeffer's framework often break his concept down into three distinct mechanisms:

1. Outsourcing critical thinking: Handing over personal responsibility for judgment to external authorities, leaders, groups, or popular media.

2. Willful ignorance: Remaining continuously uninformed or turning a blind eye without any effort to seek truth.

3. Conformity: Submerging individual conscience into a collective identity where loyalty and belonging matter more than reality.

How Does It End?

Bonhoeffer noted that stupidity cannot be overcome through instruction, debate, or mere facts. It requires an act of liberation—which usually has to happen externally first (a collapse of the power structure) before the individual can experience an internal awakening of conscience.
