Resonating or Ranting

I. Two Words, One Root

Both German words come from resonare, to resound. One branch ran through ratio and the French raisonner into the sense of reasoning things out; the other stayed with the physical business of vibrating in sympathy. In German the first branch then shifted once more: since the eighteenth century räsonieren has meant, above all, to grumble. The charge of having no consequence is now built into the word.

Resonieren, by contrast, carries a positive charge. Something resonates with me, it strikes something, it speaks to me. One says it of books, of sentences, of people, and one says it as praise.

That valuation is premature. We propose taking both words literally to begin with — the one as what it denotes in mechanics, the other as what it actually does.

II. What Resonance Is

Resonance is not a process of cognition. It is a process of amplification.

An oscillating system responds to a periodic excitation with particular strength when the frequency of that excitation matches its own. The amplitude of the response is a measure of the agreement between exciter and system — and it says nothing about the exciter itself. Whatever resonates strongly was, in substance, already there. It merely became loud.

Emotional resonance is therefore not self-confirmation because those involved are weak or comfortable. It is self-confirmation by construction. Anyone who reads a sentence and feels the click inside — yes, exactly that — has learned in that moment that the sentence matches his own natural frequency. Nothing more.

From this follows a sentence that is uncomfortable and that we nevertheless hold to be correct: whoever resonates strongly is poorly informed. Not because he is stupid, but because a high amplitude indicates that little new is in play. The information content of a message and the strength of the agreement it elicits run in opposite directions.

III. Damping

Mechanics offers an exact counterpart here, and it carries further than any metaphor.

An undamped system has a very narrow and very high resonance peak. It responds enormously at its own natural frequency and almost not at all to anything beside it. It is, in other words, highly selective and nearly blind. A damped system responds more broadly and more weakly — and in doing so represents the exciter rather than itself.

Damping is loss. It withdraws energy from the system and converts it into heat. That is why no one builds it in voluntarily, and why this holds: confirmation is lossless. Cognition is a process of loss. Where something passes through without loss, nothing has been tested.

An undamped structure does not withstand its own amplification. That is not a conjecture but the experience of structural engineering.

IV. The Echo Chamber

The word is not chosen by accident, and it is more precise than those who use it usually mean.

An echo chamber is customarily described as an information problem: people hear only what they already think. An obvious remedy follows — show them the other side. That remedy has been investigated, and it does not work. In a large American field experiment in 2018, users of a social network were paid to follow, for one month, an automated account that fed them posts from the opposing political side. The result was not convergence: one group afterwards held its original position considerably more strongly, while in the other the effect was small and not statistically significant.

In the mechanical picture this is no puzzle. An echo chamber is not an information problem but a damping problem. It is not a defective resonant system but a particularly good one: narrow peak, high quality factor, blind to everything beside it. Feed such a system a signal at a foreign frequency and you do not get a response to it. You get what the system does anyway — only stronger, because you have excited it.

It follows that information is the wrong quantity. What is missing is loss. And loss does not arise from hearing something; it arises from something costing you: having to answer, having to bear the consequence, standing before someone who does not go away.

V. The Ranting Valve

The other side looks different and is just as ineffective.

Ranting happens about something, not with someone. The object is absent and never learns of it. Testing takes place, often sharply and often correctly, but the test reaches no one who would have to answer. Criticism without an addressee is a closed circuit.

One may describe this as a ranting valve, and the image is more exact than it first appears. A valve does not prevent pressure. It prevents the pressure from bursting the vessel. It is a safety component; it protects the vessel and not the contents; and it is fitted by the same engineer who built the vessel.

Accordingly, ranting is not suppressed but supplied: broadcast slots, discussion panels, comment columns, formats. Whoever has been outraged has the feeling of having done something. The action itself does not occur, but the sensation of it does — and a need that has been satisfied does not press further.

The decisive component here is not the volume but the turnover. An object that holds for three years becomes dangerous. One that holds for three days is harmless. The valve works through the change of subject. And no one steers that change: it arises from the need of the very same people who are outraged for the next object. The outraged operate their own valve, and there is no shortage of fresh occasions.

Political satire lives on this in a particularly pure form. It does not merely release pressure; it confers superiority. Whoever gets the joke belongs to those who see through it — and seeing through feels like a position but is none. That is why the genre never loses its object: it needs it.

VI. Kant and the Permission

The formula for this stands in one of the founding texts of the Enlightenment.

Kant writes in 1784: Argue as much as you will and about what you will, but obey! The public use of reason is free — and obedience remains untouched by it. Thinking and consequence are separated in a single sentence.

One does Kant an injustice by stopping there. His expectation was that the free public use of reason would in the long run act back upon the government and change its conduct; he says so expressly. It was a lever with a very long gear ratio, not a renunciation.

But the formula stands there nonetheless, and it describes exactly the construction of the valve. It is the same sentence that secures freedom of thought and permits its inconsequence. Whoever wants the one has the other delivered with it.

VII. The Second Derivation

Everything so far has been won from mechanics. There is a second derivation that comes from an entirely different direction and arrives at the same result.

Hartmut Rosa has made resonance the basic concept of a sociology of our relation to the world. For him resonance is a relation of response between two instances that both speak with a voice of their own. It has four features: one is affected by something; one answers with one's own efficacy; both sides are changed in the process; and the process is unavailable — it cannot be manufactured, compelled or guaranteed.

Decisive for us are the third and fourth features, and decisive is the distinction Rosa himself draws: an echo is not resonance. In an echo only one's own voice returns. The second instance is missing, and because it is missing, the change is missing too.

Rosa thus says, in the language of social theory, what the section on damping says in the language of mechanics. His unavailability corresponds to the finding that a real exciter must come from outside and cannot be ordered. His transformation corresponds to loss: where nothing is changed, nothing has happened.

We take the concept more narrowly than Rosa does. For him resonance is a question of the good life, set against the counter-concept of alienation. What interests us is only the epistemic core: how does one recognise that one has heard something rather than oneself?

VIII. Cognitive Resonance

Two forms have now been described, and neither produces a third thing. Resonance in feeling binds without testing. Ranting tests without binding.

But there is a third, and it is the reason for writing this text.

Cognitive resonance is the process in which one thought meets another and sets it vibrating — not because it pleases, but because it fits. It engages a structure that was already there and shows that the structure lies differently than one supposed. That is not a feeling but a recognition of construction. And it is not the same as agreement: one can resonate cognitively with a thought one rejects, if it strikes one's own matter.

In the language of the second section: cognitive resonance is resonance with a real exciter in a sufficiently damped system. The system does not respond to itself but represents something lying outside it. That is why the response is weaker and broader than an echo — and that is why it is usable.

And that is why it costs something. Damping is loss. Cognitive resonance takes energy from what exists; it clears something away. That is the experience one has with it: it also strikes where one is oneself the object.

Emotional resonance never hurts. That is its surest identifying mark.

IX. Organisations as Resonant Systems

What holds for persons holds more sharply for organisations, because their construction demands it.

A membership organisation selects at the entrance: one joins because one already agrees. It homogenises internally, because careers run through agreement. And it penalises deviation, because offices and list positions are allocated by those from whom one would deviate. This is not a degeneration but the mode of operation, and Robert Michels described it more than a hundred years ago.

A party is therefore, by construction, a resonant system of high quality factor. The question is not whether it is one, but what damping it has built in.

And that question can be answered without requiring a political position. The features are observable. Is there a right of motion that the leadership cannot clear away? Do minority votes appear in the result? Are there arbitration bodies that decide against the leadership — and have they done so? Is contradiction treated as a contribution or as disloyalty? And where does the organisation get its information about itself: from sources it or its milieu controls, or from sources that it does not?

On this scale, parties do not lie in the same place. Whoever treats contradiction from within as betrayal, and draws his assessment of the situation predominantly from his own media circle, has a very high quality factor and a very narrow peak. Such a system is extraordinarily strong inwardly and nearly blind outwardly — and both are the same property, not a merit and a defect.

We name no names here, because the features make them unnecessary. Whoever applies them arrives at a result, and at one he can justify.

X. The Test

The real difficulty is that emotional and cognitive resonance feel identical from the inside. Both produce the same click. Anyone who relies on it can become intoxicated with a thought that does nothing but confirm what he already thought.

So a test is needed that applies from outside. We propose three questions.

First: can I name which earlier sentence of mine no longer holds? Cognitive resonance changes what exists; emotional resonance leaves it standing and makes it warmer. Whoever cannot say, after the click, what is now different has not recognised anything but merely recovered something.

Second: did it strike at a point where I was myself the object? A thought that strikes only others is suspect. Not false — suspect. The probability that a correct structural insight stops short precisely at one's own person is small.

Third: could I have said it beforehand? If so, it was confirmation. This question is the hardest, because memory works backwards: much appears in retrospect as what one always thought.

None of the three questions presupposes a conviction. They presuppose only that one asks them before passing the thought on.

XI. What Follows

For an individual person the test is reasonable. For an institution it is not, because there no one has a memory and no one is responsible.

The institutional counterpart of damping is the duty to answer. Criticism that has an addressee who must answer binds and tests at once. It is the only form that ends neither in the echo nor in the valve.

This is not a demanding requirement. It consists in recording somewhere who has to answer what, and by when. Everything further — whether the answer is good, whether it convinces, whether it changes anything — comes afterwards and is open.

As long as this coupling is missing, only the two familiar forms remain. One vibrates along with those who were vibrating anyway, and one complains about those who do not listen. Both are agreeable. Both are lossless.

And whatever passes through without loss has tested nothing.
