Psychological Triggers Are Not a List: Sort Them by the Boundary Between Mechanism and Prescription

In a list of psychological triggers, items of different kinds stand side by side wearing the same face.

“Reciprocity” is a description of an act — handing something over first. It does not come into being unless something is actually handed over, so something genuinely moves on your side. “Scarcity” is a description of a manner of presentation. It can be implemented by altering a stock display, and nothing moves on your side at all. These two sit in the list as items of equal size.

What disappears in the lining up is the difference in cost. Miss with the first and what you handed over does not come back. Miss with the second and nothing is lost. Once the difference in cost disappears, implementation leans towards the side that costs nothing.

There is a second thing the list erases. A list is a description of an observation — people respond in this way — yet it is read as the instruction, therefore write in this way. One conversion sits between the two, and at that step a premise enters: that producing the response is itself the objective. The list itself does not state that premise anywhere.

Three distinctions are handled from here. First, what the items in a list actually describe. Second, what gets added when that description is carried across into a prescription. Third, why a judgement passed on peripheral cues structurally tends not to hold.

Some questions get no answer here. How many triggers may be used, and up to what point, is not decided here. It varies with the form of the trade and the length of the relationship. Nor can which route the reader actually judged by be observed from this side. What is knowable is which route you wrote by, and no further. Explaining the individual items of the list one by one is also left out. Explanations of each item already exist in quantity, and lining up the same thing again adds nothing.

Where the damage sits is easy to locate. It is where the criterion of judgement collapses into a single question: did it work. Adopt the criterion that a rising response rate means you are right, and the case where the response rate rises while the business is harmed becomes undetectable. The harm surfaces some months later, in the form of a mailing list that does not get opened. What is in hand at that point is not a record of who entered through which announcement, but a single figure showing that the overall response rate has fallen. Since the cause cannot be identified, the next move available also points only towards raising the strength.

The dividing line sits in one place: between the description people respond this way and the instruction so induce that response. The description side is the result of observation; the instruction side carries somebody’s judgement. Receive the prescription without seeing that the judgement went in, and no memory of having chosen remains on the implementing side.

What a Marketing List of Psychological Triggers Contains

A psychological trigger is a psychological factor acting as the trigger when a person chooses something. It is described as what settles a purchase, what works as the occasion for an action.

Representative items get shown as a list. Seeing others use something makes you want to use it. What an authoritative figure says is easier to accept. What you have once affirmed is hard to deny later. Small numbers make value look higher. Receiving something first creates a wish to return it. All of these are tendencies observed commonly across many people. Some articles line up thirty items, some fifty, and the sheer count of items is sometimes presented as the value of the article.

Books get cited as sources. Robert Cialdini’s Influence is the representative one, organising six principles: reciprocity, consistency, social proof, liking, authority, and scarcity. The set of roughly thirty items compiled by the advertising writer Joseph Sugarman is also widely cited, together with the term psychological trigger itself.

Uses are shown concretely as well. What to place where on a sales page. Which element to put in a subject line. How to structure the presentation of a price. It is offered as a correspondence table between elements and placements.

Experiments and cases get attached as grounds for the effect. The report is that the same product draws a different response rate when the manner of presentation changes.

As descriptions, all of these are accurate. The tendencies listed are genuinely observed, and it is a fact that the response changes with the manner of presentation. The value of the knowledge is high. Between writing with an understanding of how people respond and writing without it, the former tends to reach the reader better.

Look now at what the whole set takes for granted. The list is offered as a set of tools. Usable things are lined up, and you select according to the situation. Use is the premise.

Organise it fully as a set of tools and the question of what it is used for moves outside the list. The list teaches how people respond; it does not teach whether that response ought to be produced. That it does not teach this is not a defect of the list. Whether something may be used is not contained in a description of an observation.

The problem is that the question, once outside, is not picked up anywhere. The writer reads the list and implements. When what was implemented does not work, the thing reviewed is the strength. It did not work, so make it stronger. That direction is complete within the list, so it can be travelled indefinitely.

Differences in kind survive on the list’s own side too. Sugarman’s compilation lines up items observed in the practice of writing advertisements, arranged close to the order of use. Cialdini’s six principles line up as the result of organising experiments in social psychology. The first is a record of practice, the second a summary of research, and the two are confirmed in different ways. Rearrange them into a single list and this difference of provenance disappears as well. What remains is an impression that all of them work about equally.

What Is Written in the List Is Mechanism, Not Prescription

A mechanism is a description that such a working exists. A prescription is an instruction to act accordingly.

“Limited numbers make value look higher” is a mechanism. It stops at describing an observed fact. “Therefore display the stock count” is a prescription. An instruction to act has been derived from a description.

Between the two sits a logical leap. From “people respond in this way” you cannot derive “therefore induce that response”. In between sits a judgement that inducing it is permissible.

The opposite prescription can be derived from the same mechanism. “Limited numbers make value look higher. Therefore inspect whether you are writing in a way that makes numbers look limited when they are not.” This too is derived from the same mechanism, differing only in direction. The fact that two prescriptions issue from one mechanism shows that the mechanism side does not settle the prescription.

This is not a discussion of ethics. It is a structural point: a step exists in the passage from mechanism to prescription. When that step is invisible, the prescription appears to carry the same strength as the mechanism.

The difference in strength is a difference in how each was confirmed. “Scarcity works” has been confirmed in experiments. “Therefore make the stock look small” has not been confirmed in any experiment. The strength of the first never transfers to the second, yet lined up in list form the two become indistinguishable.

Not every prescription carries a problem. Displaying the count for something whose numbers really are limited is the presentation of a fact. The parting comes where the fact itself is adjusted in order to make the mechanism operate. Write “only a few left” when stock is ample, and what has moved is not the presentation but the description of the fact.

The place where the boundary vanishes can also be located. The books cited as sources mostly do write the conditions and the limits of their experiments. What erases the boundary is the process of summarising into a list.

Summarising drops conditions. “In what situation, to what degree, and for whom did it work” does not fit the list form. What remains is the item name and the conclusion that it works. An item with its conditions dropped looks usable anywhere.

When the boundary is invisible, no sense of having chosen is available. The person who read the list and implemented does not think they chose anything. They feel they merely did as they were taught. Without a sense of having chosen, no occasion for later review arrives either.

This boundary is not drawn in order to make the writer’s burden heavier. Once it is clear that a step sits between mechanism and prescription, the prescription side alone becomes replaceable. The description that scarcity works cannot be altered, but what you write in response to it can be selected. Where the step is invisible, accepting the mechanism means accepting the prescription along with it, and the place where selection happens disappears entirely.

At the Step of Conversion, the Objective Splits in Two

At the step of moving to a prescription, what is taken as the objective gets settled. The objective divides in two.

One is producing a response. Registering, clicking, buying. It is achieved once the act occurs.

The other is that a judgement gets made. The other party decides, in the light of their own situation, whether this is necessary. Even where the decision is “not necessary”, it has been achieved.

The two overlap in many situations. Where necessary information reaches the person who needs it, a response occurs as well. They fail to overlap where a response occurs in someone who does not need it.

Take the response as the objective and this difference becomes invisible. The response of the person who needed it and the response of the person who did not enter the same single figure.

Set a deadline and registrations increase. Among the increase are people who would not have registered without the deadline. Those people registered not because the content was necessary but because a deadline existed.

The difference does not appear in the registration count. It appears afterwards. Not opened, no replies, no response to announcements. And at that stage the cause cannot be identified. Which of the two each person on the list was is not recorded anywhere.

Widen the entrance and narrow later — that order looks workable too. Narrowing costs something, though. And writing addressed to the list before narrowing gets written on the premise that people who do not need it are mixed in. Writing produced on that premise reaches even the people who need it only thinly.

Taking the response as the objective is not always an error. Where the audience has already been narrowed, the two objectives roughly coincide. They part at the stage where the audience has not been narrowed.

The two objectives are also measured by different indicators. Take the response as the objective and you look at the number of clicks. Take the judgement as the objective and you look at why the people who did not click did not click. The latter is information that reaches your side with difficulty.

Because it arrives with difficulty, it goes unmeasured. What is not measured is not improved, so even with judgement set as the objective, the degree of attainment stays unknown as the work proceeds. This needs stating honestly. The benefit of taking judgement as the objective cannot be demonstrated by measurement.

Something else happens on the writer’s side. Take the response as the objective and the skill grows in the direction of response. What to write to make people move becomes clear, and what to write so that the other person can judge falls outside the range of practice. Some years on, the second has become unwritable.

A Judgement Passed on Peripheral Cues Tends Not to Hold

The difference between producing a response and having a judgement made has empirical backing.

Richard Petty and John Cacioppo, working in persuasion research, set out a framework dividing attitude change into two routes (Petty & Cacioppo, 1986, Advances in Experimental Social Psychology, 19, 123–205). One is the central route, where change comes through scrutiny of the content itself. The other is the peripheral route, where change comes through cues outside the content — the attractiveness of the speaker, the sheer volume of information, the reactions of others.

What matters is that the two routes differ in the property of their result. An attitude changed through scrutiny of content persists over time and resists collapse when contrary information arrives. An attitude changed by cues does not persist and collapses easily.

What the framework covers is worth placing accurately. This is a synthesis of persuasion research rather than a single experiment measuring the effect of a particular advertisement. What it indicates is a direction: how the change endures depends on which route it travelled.

Many of the items lined up in a list of psychological triggers run the second route. Authority, the reactions of others, scarcity — none of these is the content itself. They are cues used in place of judging the content.

A judgement moved by a trigger therefore structurally tends not to hold. This is not a matter of writing badly; it is the property of that route.

Seen from the business side, failing to hold appears as cost. A judgement that does not hold has to be rebuilt each time. The next announcement requires a stimulus of the same strength. And since the same strength draws a lower response, the strength gets raised.

Let the first occasion run on cues and convey the content afterwards — that order is conceivable. The order works. There is a condition, though. It works only where the person who came in actually reads the content that follows. Someone who entered on cues entered in a state of low interest in the content, so the probability of not reading is high. And where it is not read, the route does not switch.

Scrutiny of content also requires capacity on the other person’s side. Low interest, no time, too much material to judge by. In such situations anyone relies on cues. Preventing the use of cues is not possible. What the writer can do is place the content next to the cue.

The distinction earns its keep in one more practical situation: whether a piece that drew a good response can be reused. A piece that passed on cues tends not to work a second time on the same reader. Familiarity sets in on the first pass. A piece that passed on content tends not to degrade for the same reader, because the content has not changed. Whether something is reusable appears as a difference of route.

A judgement that does not hold also has a delayed effect. It shows up as a state of being unable to explain why you bought. What is damaged then is not the satisfaction of that one transaction but the relationship with the writer.

Without Knowing, the Choice Not to Use It Is Unavailable

Nothing so far points to a conclusion that psychological triggers should not be learned. The opposite.

Mechanisms operate whether or not you use them. The scarcity effect occurs without your intending it. Write “three seats remaining” as a plain fact and the effect arises.

Without knowing, you cannot tell what you have pulled. You write what you take to be a fact and have in reality produced a response. And since it was not intended, it does not get inspected either.

Suppose you write a piece that lines up your track record. As far as you are concerned, you have listed facts. On the reader’s side, however, it is working as a cue of authority. Instead of scrutinising the content, they judge by the volume of the record.

The state looks convenient from the writer’s position, because the response is good. The judgement that passed, though, tends not to hold.

Knowing, you can choose. Having written the record, you can add a line: “This record is not proof of whether it applies to your situation.” Add it and the route of judgement returns to the content side.

This is not weakening the effect but reselecting the route. Part of the response that came through the record is lost. What remains is the people who read the content and judged. The number falls and the proportion that holds rises.

Which to choose varies with the form of the business. Between a trade completed in a single transaction and a trade premised on a continuing relationship, the value of holding differs. Situations where holding is unnecessary genuinely exist. What this article handles is the second form — the business of staying with a small number of people for a long time.

There is a generalisable shape here. In a state of not knowing a working, you cannot “not use” that working. The choice of not using is open only to someone who knows the working exists.

What someone who does not know is doing is not refraining from use, but using unconsciously. Intention does not reach the reader’s side. What reaches them is only the result. And seen from the result, what was pulled unconsciously and what was pulled deliberately cannot be distinguished.

Holding the knowledge also makes other people’s writing readable. Where and what is being pulled becomes visible, so your judgement as a recipient changes too. That is not a benefit for you as a writer, but it may be the most practical use of this knowledge.

Becoming able to read has one side effect. Once the places where something is pulled become visible, the content of that piece becomes easy to discount as well. That a cue has been placed and that the content is thin are separate matters, so the discount is not accurate as a judgement. The way to tell them apart is to remove the cues and see whether the claim stands on the remainder. If it stands, the cues that were placed were auxiliary.

Applied After Writing, the List Becomes an Instrument of Inspection

The same list, applied after writing, becomes an instrument of inspection. You take the finished piece and apply it item by item.

The question is one. “By what, other than content, is this piece trying to move the reader?”

The procedure runs in three steps. From the finished piece, delete every claim and every ground. Look at what is left.

What remains is the track record, other people’s voices, deadlines, limits on quantity, the word “now”, the names of authorities, and description that touches the emotions. These are the cues outside the content.

Next, see whether the piece stands on the remainder alone. If it stands, the piece runs mainly on cues. If it does not, the cues are working as support.

There is no good or bad in this determination. What it yields is a single fact: which route you are currently writing by.

The same procedure applies to other people’s writing. Delete the claims and grounds from a writer you take as a reference, and look at the remainder. Take a piece with a large remainder as your model and the skill that grows is the skill of the cue side. How you select a model settles the direction in which the skill grows.

Counting emotional description as a cue may look too strict. Here the role of the description divides it. Description that lets the reader recognise their own situation is on the content side. Description placed in order to hurry or unsettle the reader is on the cue side.

The reading is settled by what the reader does after taking in the description. Move to check their own situation, and it is on the content side. Move immediately to act, and it is on the cue side.

A piece with cues entirely eliminated cannot be written. The choice of words, the length of sentences, the order — all carry effects outside the content. What is attainable is not elimination but knowing what is there.

Inspection has places it tends to miss, too. The heading and the opening tend to fall outside the scope of inspection. Deleting claims and grounds is performed on the body, so the line placed ahead of it survives unexamined. In practice this is where cues tend to be placed thickly. Begin the deletion from the heading and they emerge.

The order of inspection carries meaning as well. Look at a list before writing and you acquire an eye for what can be used. Apply the list after writing and you acquire an eye for what you have used. The same list becomes a different instrument depending on the order.

Beyond that, workings not on the list will not emerge however you apply it. A list is not exhaustive; it is a lining up of what has been well observed. What inspection can catch is only what someone has already named.

Continue inspecting and the stage before writing changes. You come to confirm first the claim that survives with the cues removed. When the claim is weak, the order that settles in is to return to the claim rather than to add more cues.

Only Handing Something Over First Differs in Property

Among the items lined up in the list, one is handled differently. The item of handing something over first.

The other items concern the manner of presentation. Change how it looks and they are implemented. Scarcity, authority, the reactions of others — all can be processed as questions of how something is conveyed.

Handing something over first cannot be implemented by how it is conveyed. It does not come into being unless something is actually handed over. Here alone, something moves on your side.

The difference appears on the route side as well. Where what was handed over genuinely proved useful, the other party continues the relationship as the result of scrutinising content. What served as material for judgement was the content itself, not a cue.

Where it did not prove useful, the material for judgement is likewise content. The other party leaves. Whichever way it falls, the judgement is passed on the content side.

Handing something over first is itself a technique for creating pressure to reciprocate — that reading is available. Designing it as pressure is possible. It applies where what is handed over is built on the premise of recovering it later. Handing over a fragment and charging for the continuation is handing over in appearance only.

The parting line is whether what was handed over is complete on its own. Where it is complete, the other party can stop at having received it. Only a relationship that continues from a state where stopping was possible is a relationship continued by judgement.

Hand over something complete and a worry arises that the continuation becomes unnecessary. In practice the reverse tends to occur. Where something complete proves useful, interest moves to the whole territory that writer handles. Handed a fragment, interest stays fixed on the single point of the continuation.

There are stages where nothing can be handed over. Force something into existence in a period when neither record nor knowledge has accumulated, and what comes out is thin. Here, not handing anything over is the more honest course.

Adopt the form of handing over first and cost runs ahead on your side. Whether it is recovered is left to the other party’s judgement after receipt. Leaving the judgement with the other party means taking on that uncertainty yourself.

This cost does not arise for the other items. An implementation that only changes how something looks loses nothing when it misses. Only the form of handing over first fixes a loss on your side when it misses. That is probably why this alone is seldom carried out among the items on the list. The difference in cost between reciprocity and scarcity surfaces at this item and no other.

The level of what is handed over is affected by the same difference. Refinements of presentation cost the same whether the quality goes up or down. What is handed over costs more as its quality rises. A writer who adopts this form therefore settles the quality of what is handed over by their own judgement. There is one rule for settling it: is this at a level you are content with even if the recipient never comes back. Anything built at a level that requires them to come back turns into a fragment.

Raising the Strength Widens the Audience and Thins the Relationship

The strength of a trigger carries a structural consequence.

A strong stimulus reaches people of low interest as well. This gets explained as an advantage, and it also means that the average interest of those reached falls.

An announcement written in strong terms draws responses from many people. Of those who responded, though, the proportion who did so out of interest in the content is lower than for a measured announcement.

The next announcement gets written to this list. People of low interest are mixed in, so the same strength no longer moves them. Raise the strength and people of still lower interest come in.

This is a one-way process. An average once lowered is hard to raise afterwards. Methods exist for having people leave the list, but those who tend to leave first are the ones with high interest. People of low interest are not reading in the first place, so they never perform the act of leaving.

At scale the absolute numbers still increase — that reading holds. What increases is the absolute number of responses, not the absolute number of judgements. And since writing gets calibrated to the average of the list, writing addressed to people of high interest becomes impossible to produce.

Forms of business in which scale carries value exist. Where advertising revenue is the axis, or where unit prices are low and repetitions frequent. What this article handles is the business of staying with a small number of people for a long time.

Strength also has an irreversibility. A reader once accustomed to strong terms receives measured terms as “weak”. The same content stops reaching them.

This is not a problem on the reader’s side. What created the standard is your own past writing. Strength operates not as a demand made of the reader but as a history you have accumulated.

The process of raising the strength goes unnoticed. Each increment is small and looks like a reasonable judgement at the time. Only by lining up several years of it does it become clear that what you are writing has changed.

There is one way to check. Read the announcement you wrote a year ago alongside the most recent one. If a difference is legible, the process is under way.

The only thing to line it up against is your own past writing. Comparison with other people’s writing yields nothing, because the standards differ. What is being measured is not the absolute value of the strength but the movement within your own record.

Where movement has occurred, there is only one way back: lower the strength and hold the state of reduced response for a while. What falls away is the portion you were borrowing forward during the period of raising it. Throughout, the figures move downwards. Whether the policy can be maintained while watching downward figures is the actual parting point. Reverting here is not unusual. That is not a criticism of reverting; it is a statement that the force pulling back comes from the structure.

Read Which Route You Wrote By, Before Publishing

Which route the piece runs can be read on your own before you publish. There are three readings.

Delete the claims and grounds, and see whether it stands on the remainder. If it stands, the piece runs on cues. If the claim stands even with the remainder entirely removed, it runs on the content side. Most pieces sit somewhere in between, but which way they lean is legible.

See whether the opposite conclusion can be added. Write “however, this is not required for those to whom the following applies” and then actually list three conditions. If you cannot list them, the audience is not narrowed. If the piece survives the addition intact, it stands on the content side. If it breaks, cues were holding it up.

What to look at is behaviour after an interval: not the moment of registration but opens and replies two weeks later. A judgement that passed on cues tends not to have survived by that point. In figures it appears as a high initial response rate followed by a sudden drop in engagement.

Neither reading looks at the response rate itself. The response rate rises on either route.

Of the three, the third cannot be used before publishing, since it requires two weeks of observation. The first and second are usable before publishing, but you are the one judging, so oversights remain.

There is a way to reduce oversights: keep the list to hand and apply it mechanically, item by item. Search by introspection and you find only what you consciously used. Apply the list and what you used unconsciously emerges. The fact that the items on the list are not uniform in kind — earns its keep here. The items that cost nothing are the ones that slip in unnoticed.

No number is offered for how many may be used. Neither the count of cues, nor the number of items of record, nor the cases in which a deadline may be set. These vary with the form of the trade handled and the length of the relationship. Offering a figure here would settle the judgement for you, without looking at those conditions.

What stays in hand instead is a set of three distinctions. The boundary by which a list is a description of mechanism rather than a prescription. The property by which a judgement passed on peripheral cues structurally tends not to hold. And the fact that without knowing, the choice of not using is unavailable. Hold those three and you can begin reading, on your own, which route the piece you have just written passes through.

Individual mechanisms are handled elsewhere: do not use loss aversion to stoke urgency covers how a reference point gets placed, and where social proof applies covers the conditions under which someone else’s judgement gets borrowed. What happens in the reader’s first instant with a piece of writing is set out in the adjudication that precedes the three NOTs. The idea binding all three together — handing over the judgement — is handled by what verbalisation is.
