What if the real problem is not getting users, but selecting the wrong ones?
Most growth advice treats acquisition like a volume game: add a referral loop, launch a free trial, slap on a coupon, sprinkle in gamification, and watch the numbers rise. But there is a more uncomfortable question underneath all of it: what kind of user are you teaching your product to attract?
That question matters because every acquisition mechanism is also a selection mechanism. It does not merely bring people in. It sorts people. It decides who feels invited, who feels rewarded, who feels rushed, who feels clever, and who feels cheap. In other words, growth channels do not just expand demand. They reshape the population that your product serves.
This is where an unexpected connection appears. The same logic that explains how people learn best in the zone of proximal development can explain why some growth systems work and others quietly corrode the business. The best teaching happens just beyond current ability, with the right support. The worst incentive systems do the opposite: they attract people based on the incentive itself, not on genuine readiness or fit.
The deep tension is this: good growth, like good teaching, should reveal latent fit, not manufacture false participation.
The product equivalent of scaffolding
In learning, progress is fastest when support is calibrated. Too little help and the learner fails. Too much help and the learner becomes dependent, passive, or disengaged. The sweet spot is scaffolding, a temporary structure that helps someone perform just beyond what they could do alone, until they can do it independently.
That is a beautiful model for product design and onboarding. The strongest products do not simply “acquire users.” They create a guided path into competence. Think of a photo editing app that does not overwhelm a novice with 100 tools, but instead offers a few smart prompts, a sample project, and a clear next step. The user is not bribed into signing up. The user is helped into becoming successful.
Now compare that with a coupon or referral scheme. A coupon often does not scaffold understanding. It scaffolds price sensitivity. A referral often does not scaffold commitment. It scaffolds social extraction, where someone is nudged to sign up because a link was shared, not because the underlying job to be done is deeply felt. Free trials can be even trickier. They can be useful, but when poorly designed they attract people who want access without intent, exploration without resolution, sampling without adoption.
This is the hidden parallel: scaffolding shapes capability, incentives shape selection. One helps people grow into value. The other often filters for people most responsive to the bait.
The best onboarding teaches users how to succeed. The worst incentives teach them how to wait for a better deal.
The distinction is subtle but decisive. A learner in a well scaffolded environment becomes more competent over time. A user drawn in by the wrong incentive may become more dependent on external prompts, more price anchored, and less intrinsically committed. What was meant to expand the market can end up diluting the product’s fit.
Incentives are not neutral. They are filters that change the population
It is tempting to think of incentives as simple accelerators. Offer something, and more people show up. But incentives do something less obvious and more powerful: they create negative selection.
If you lead with discounts, you attract people for whom discounts matter disproportionately. If you lead with a referral reward, you attract people who are highly responsive to referral mechanics. If you lead with gamification points, you attract people who like the game of earning points, which may or may not correlate with actual long term product value. In each case, the mechanism does not just persuade. It sorts.
Imagine a gym that advertises, “Sign up today and get two months free.” Who arrives? Some genuinely motivated beginners, yes. But also bargain hunters, dabblers, and people who are mainly collecting the novelty of a new start. Now compare that with a gym that offers a structured beginner pathway, a trainer session, and visible progress milestones. The first system attracts the incentive sensitive. The second attracts the goal sensitive.
This distinction matters because businesses often mistake a spike in signups for evidence of fit. But a spike can be a diagnostic warning. If the mechanism was the main draw, then the users are often selected for responsiveness to the mechanism rather than loyalty to the product.
There is a second, deeper cost: cannibalization. A promotion can pull forward users who would have arrived anyway. That means the company pays to acquire people who were already on their way, simply arriving earlier and cheaper in appearance, but more expensive in reality. Like teaching a student to memorize the answer key before they have learned the concept, the metric looks good while the underlying understanding is weaker.
This is why the question is not “Did the channel work?” It is “What kind of user did it create, and at what hidden cost to the future?”
The overlap between learning and growth: readiness beats reaction
The most interesting commonality between education and acquisition is that both are about timing. In learning, a task should sit just beyond the learner’s current ability. In growth, an offer should meet someone at the moment when the product is genuinely relevant, not merely when a promotion makes it visible.
A useful mental model is to think in terms of readiness versus reaction.
Readiness means the person already has a latent need, and the product or teacher helps them cross the gap.
Reaction means the person responds to the external stimulus itself, whether or not the underlying need is strong.
Good learning systems optimize for readiness. Good products do too. A person who is ready to learn piano will benefit from a teacher who gives the right amount of support. A person who is not ready may still buy a keyboard because it is on sale, but that does not make them a learner. It makes them a responder.
The same applies to software, marketplaces, and consumer products. A note taking app should attract people who are trying to think better, not merely people chasing a week of premium access. A ride sharing app should attract people who want reliable transportation, not only people hunting for first ride credits. A creator tool should attract people who are trying to create, not just people who enjoy onboarding rewards.
Scaffolding works because it increases the user’s ability to act. Incentive hacks often work only because they increase the chance of a response.
This is why the best product growth often looks less like advertising and more like education. Great products reduce the gap between intent and competence. They make the first successful use obvious, then the second, then the third. Users do not feel manipulated into action. They feel assisted into progress.
When that happens, the product is not buying behavior. It is cultivating it.
Why good growth feels like shared understanding
In learning theory, there is a powerful idea called intersubjectivity: two people start a task with different levels of understanding, but through interaction they arrive at shared meaning. That is the real goal of scaffolding. Not obedience. Not dependence. Shared understanding.
The same is true for durable product growth. The best products do not just get a user to click. They create a shared understanding between the company and the customer about what the product is for, when it matters, and how success is achieved.
Consider a project management tool. If the onboarding process simply says, “Invite your team, get started, try this template,” that may generate activation. But if the product also helps the user understand why the tool is structured this way, what workflow it supports, and what pain it is meant to solve, the relationship changes. The user is no longer merely activated. The user is aligned.
That alignment matters because it is the difference between a temporary transaction and a durable habit. People who understand why something matters are less sensitive to small price changes, less likely to churn when novelty fades, and more likely to recommend the product for the right reasons. They are not just persuaded. They are converted into informed participants.
This gives us a better framework for evaluating acquisition channels: ask whether the channel creates shared understanding or just surface action. A good onboarding flow, tutorial series, or expert community can deepen understanding. A coupon usually cannot. A referral can, but only when the referrer is actually transmitting context, not just a link.
In that sense, the most valuable growth channels are not those that merely move the signup number. They are the channels that improve the quality of the relationship between the user and the product.
The growth equivalent of a bad teacher
A bad teacher can make a class look successful while producing shallow learning. They can overhelp, overstructure, or reward compliance in ways that mask confusion. The student finishes the lesson, but cannot transfer the skill elsewhere.
A bad acquisition strategy does something similar. It makes the funnel look efficient while producing shallow users. They arrive, convert, maybe even complete a few actions, but they do not become deeply engaged. They were not selected for fit or readiness. They were selected for responsiveness.
This is why some growth mechanics quietly degrade over time. The more you train the market to expect a reward before value, the more you invite users who are optimizing for the reward. You do not get a larger version of your best customer. You get a different species of customer.
Think of it like fishing with a noisy lure. At first it works because it catches attention. But over time, the pond fills with fish that chase noise, not food. When you switch to a quieter, more natural approach, the volume may fall, but the quality rises. The long term business is not built on the most reactive crowd. It is built on the crowd most likely to stay.
This is why adding more mechanics can backfire. A referral system may look clever, but if it becomes the center of gravity, the product begins to orbit its own incentive structure. The company spends energy optimizing the bait instead of improving the meal.
The most important strategic question is therefore not, “Can we motivate a signup?” It is, “Can we construct a path that reveals genuine demand while helping the right users succeed?”
Key Takeaways
Treat every incentive as a selection device.
Ask what kind of person it rewards, filters in, or filters out. The mechanism matters as much as the message.
Optimize for readiness, not reaction.
The best users are not merely the most responsive to offers. They are the ones already close to needing the product, and ready to succeed with it.
Use scaffolding before incentives.
Onboarding, tutorials, templates, and guided workflows often create better customers than discounts or rewards because they build competence, not dependency.
Watch for cannibalization.
A channel that looks efficient may simply be pulling forward users who would have arrived anyway. Measure long term retention, not just short term conversion.
Ask whether your growth creates shared understanding.
The strongest products teach users what success looks like. If your channel increases signups but not clarity, it may be weakening the business.
The deeper lesson: growth should enlarge fit, not distort it
The strongest connection between learning and acquisition is that both are about helping a person cross a gap without losing the truth of who they are. In education, that means supporting the learner just enough to make growth possible. In business, it means helping the right customer discover value without bribing the wrong one into temporary participation.
This is the part most growth teams miss. They think the challenge is persuasion. Often the real challenge is formation. What kind of user is this product forming over time? What kind of behavior is the business rewarding? What kind of future is being selected by the present channel?
If you see incentives as shortcuts, you will eventually build a product around shortcuts. If you see scaffolding as a way to reveal competence, you can build a product around mastery. One yields a crowd. The other yields a customer base.
And that leads to a final reframing:
The best growth does not trick people into wanting your product. It helps the right people become the kind of user who can truly benefit from it.
That is why the most durable companies are often not the ones with the flashiest acquisition tricks. They are the ones that understand selection, readiness, and support as a single system. They know that every user journey is also an educational journey. And they build accordingly.
