Is it possible to be an intelligent person and yet act stupidly? Why do some people defend ideas without examining them, repeat slogans without verifying them, and reject any information that contradicts their convictions?

The German theologian Dietrich Bonhoeffer , who opposed Nazism and was executed by Hitler’s regime in 1945, reflected on these issues in dramatic historical circumstances.

His thinking remains remarkably relevant today. It invites us to ask ourselves whether we are using our intelligence to seek the truth or whether, on the contrary, we are giving up on thinking for ourselves.

1. Stupidity is not a problem of intelligence

Bonhoeffer begins with a provocative statement: ” Stupidity is a more dangerous enemy of good than malice .” Why?

A person who acts maliciously may know they are causing harm and try to hide it. However, someone who refuses to think may collaborate with evil, convinced they are doing the right thing.

We are not necessarily talking about a lack of knowledge, education, or intellectual capacity. A person can have an extraordinary education and, at the same time, uncritically accept the ideas of their group, their leaders, or those who exert influence over them.

The problem arises when we stop examining the arguments, close ourselves off to the facts, and confuse our convictions with the truth.

Being intelligent doesn’t guarantee you’re thinking well. And having a strong opinion doesn’t mean you’re right.

2. The danger of repeating slogans

Bonhoeffer observed how people can become spokespeople for ideas they haven’t personally examined . Instead of reasoning, they repeat slogans, catchphrases, and arguments provided by their environment.

This phenomenon is not just a thing of the past. We find it in politics, on social media, in everyday conversations, and also in the business world.

Sometimes, a statement is accepted because it’s repeated by someone we admire. Other times, it’s because it aligns with our group’s thinking. It can also happen that an idea is considered true simply because it appears frequently in the media. Repetition can create familiarity, but familiarity doesn’t prove truth.

When we stop verifying information, we lose autonomy. We are no longer the ones examining ideas: received ideas condition our way of interpreting reality.

3. Manipulation needs people who don’t ask questions

This is one of Bonhoeffer’s most important lessons. Power can be especially dangerous when it gets people to relinquish their independent judgment. It doesn’t need to convince them with sound arguments if it can get them to accept its slogans without question.

Manipulation works best when we don’t question who is communicating, what they intend to achieve, what facts they present and which they omit. It also works best when we mistake emotionally appealing communication for truthful communication.

Images, stories, music, words, and audiovisual resources can evoke intense emotions. They are legitimate communication tools, but they can be used both to inform and help understand, and to conceal facts, oversimplify complex problems, or influence decisions. Therefore, when faced with a particularly persuasive message, it’s worth asking yourself a few questions:

• What facts support what you’re telling me?
• What information is missing or has been presented incompletely?
• What emotions is it trying to awaken in me?
• Does it invite me to reflect or does it expect me to accept a conclusion without questioning it?
• Am I willing to change my mind if better arguments emerge?

These questions don’t make us distrustful of everything. They help us distinguish between reasonable trust and gullibility.

4. The challenge of Marketing: to persuade without manipulating

From the perspective of values-based marketing, Bonhoeffer’s reflection poses an important responsibility.

Marketing has the power to influence what people know, want, value, and decide. Therefore, the ethical question is not simply whether a campaign is effective, whether it generates a lot of traffic, or whether it increases sales. We must also ask ourselves what that communication does to the people it is targeting.

Does it help them better understand their needs? Does it provide them with enough information to make free decisions? Does it respect their intelligence and judgment? Or does it exploit their fears, insecurities, and desires to provoke an immediate reaction?

A campaign can be creative, technically impeccable, and commercially successful, but use resources that hinder a truly free and informed decision.

Responsible marketing should not take advantage of consumers’ lack of knowledge . It should help them better understand what they are buying, what need it satisfies, and what the consequences of their decision are.

Values ​​should not be a mere communication tool. They should be a criterion for making business decisions.

This idea compels us to go beyond advertising messages. A company doesn’t demonstrate its commitment to the truth simply by including the word “transparency” in a campaign, but rather by communicating honestly, acknowledging its mistakes, and fulfilling its promises.

Nor does using emotional imagery demonstrate a commitment to people. It demonstrates it when products, services, and customer relations truly contribute to improving people’s lives.

5. Thinking for oneself also requires humility

Critical thinking is not about contradicting everyone or considering yourself more intelligent than others.

Nor does it consist of systematically distrusting institutions, experts, or the media. Thinking for oneself requires comparing sources, listening to different arguments, recognizing the limits of our knowledge, and accepting that we can be wrong.

Sometimes, the greatest sign of intelligence is changing our minds when we realize we were wrong. That’s why we must be wary of a misinterpretation of Bonhoeffer: using his reflections to call those who disagree with us stupid.

If we do that, we turn an invitation to think into a tool to discredit the adversary. We fall, precisely, into what we intended to denounce.

The important question is not whether others think badly of us, but whether we are willing to examine our own ideas.

6. Regain the freedom to think

Bonhoeffer doesn’t invite us to despise people, but rather to understand how certain circumstances can lead them to relinquish their autonomy. This reflection has implications for education, politics, communication, and business.

We need people who can distinguish facts from opinions, arguments from slogans, and legitimate persuasion from manipulation. We need companies that respect the intelligence of their customers, leaders who welcome uncomfortable questions, and organizations where reasoned dissent is not considered disloyalty. And we need a society that values ​​knowledge, dialogue, and the honest pursuit of truth.

From a humanistic perspective, thinking is not merely an intellectual capacity. It is also a moral responsibility: our decisions affect other people, and we cannot completely delegate our judgment to those with more power, prestige, or influence.

One last question

In a society saturated with information, advertising messages, opinions and slogans, perhaps the real problem is not that we lack information, but that we lack the time and will to think about it.

Artificial intelligence, social media, and new technologies can help us better understand reality. But no tool should replace our responsibility to examine what we receive, assess its consequences, and make our own decisions.

The question Bonhoeffer leaves us with remains uncomfortable: do we really think for ourselves or do we simply repeat what others want us to think?

At Marketing and Services, we advocate for marketing that serves people, services that improve lives, and values ​​that guide decisions. To achieve this, we need more than just good campaigns and attractive messages. We need free people, capable of thinking, seeking the truth, and making responsible decisions.

Because the goal of marketing shouldn’t be to get people to think less so they buy more, but to help them make better decisions.

Thinking for oneself is a form of freedom. Respecting the freedom of thought of others is an ethical responsibility.
