How Overprescribed Marketing Tactics Are Fueling Brand Resistance and What Thoughtful Marketers Can Do About It

Once Upon a Time, Antibiotics Changed Everything

When antibiotics first appeared, they were nothing short of miraculous. They saved lives, healed infections, and revolutionised modern medicine. For the first time in history, a single pill could stop something that used to be fatal.

But over time, success bred overuse. Antibiotics were prescribed “just in case.” Every sniffle, sore throat, or minor infection became a reason to use them.

Eventually, the medicine that once healed was undermined by overuse. Overprescription spawned resistance. In many cases, standard treatments became less reliably effective – especially for routine infections – forcing physicians to escalate, combine, or rethink the approach altogether.

Antibiotic resistance isn’t a distant or theoretical issue – it’s one of the most urgent medical challenges of our time. According to The Lancet (2024)[i], antimicrobial resistance now is estimated to cause more than 1.27 million deaths annually and continues to accelerate due to overuse and misuse across health systems worldwide.

What began as a miracle of modern medicine has become a cautionary tale in overapplication: when a good thing is used too often, too broadly, or without discernment, its power weakens.

Marketing has, unfortunately, followed a remarkably similar path.

Once upon a time, email funnels, heartfelt storytelling posts, and formulaic “this made me think of that” content felt fresh. It created connection, nurtured trust, and converted attention into action. But then… everyone started doing them.

Another funnel, another “authentic” story – and thus we created our own form of resistance.

Audiences become immune – not because the idea was inherently wrong, but because it was once considered “best practice”. So as soon as the capability to emulate these became broadly accessible (thanks AI) it quickly became overused.

And what once felt like magic began to feel manufactured.

That same pattern of overuse and diminishing returns has played out across the marketing landscape

The Marketing Microbiome: What We Broke

Just as overuse of antibiotics disrupted the body’s microbiome, overuse of marketing formulas has disrupted our collective attention span.

Audiences have developed psychological resistance. They’ve learned to spot the signs of manipulation – the strategic vulnerability, the contrived relatability, the perfectly timed “authentic” moment that isn’t really authentic at all.

They may not say, “I’m immune to marketing,” but they feel it.
They don’t unsubscribe or complain – they tune out.
They don’t argue – they scroll and ignore.

What once built trust now triggers scepticism.
What once felt like connection now feels like performance – frustrating even for marketers who’ve used these tools responsibly, only to find their impact diluted.

The marketing ecosystem has become oversaturated, over-treated, and undernourished. And like any ecosystem under strain, it’s showing symptoms – low engagement, declining reach, emotional fatigue.

A 2024 ScienceDirect review explains the biology behind resistance –  repeated, low-level exposure to antibiotics teaches bacteria how to survive future attacks[ii]. It’s not that the drug suddenly stops working; it’s that the bacteria get smarter.

They learn, adapt, and defend themselves more effectively each time they encounter the same threat*.

We are experiencing this in real time.

Repeated exposure to the same formula – identical sales patterns, predictable discounting, familiar launch formats, and recycled emotional hooks – sharpens audience discernment. They recognise the pattern. What once stirred emotion now triggers scepticism.

The same fatigue is visible on social platforms. Posts that once drove engagement through personal storytelling now attract lower interaction as audiences learn to spot “performed authenticity.” What was once a differentiator has become a template – and templates rarely build trust.

From Antibiotic Overuse to Marketing Fatigue

The parallels are striking.

• Antibiotics were prescribed “just in case.”
  Formulaic funnels are created “just in case someone converts.”
• Overprescription created resistance.
  Over-automation created numbness.
• Patients stopped responding to the medicine.
  Audiences stopped responding to the message.

The more we push, the less people respond. When communication becomes formulaic, it stops being communication.

In a comprehensive 2025 clinical meta-analysis[iii], researchers confirmed that shorter, more targeted courses of antibiotics were just as effective as longer ones for many common bacterial infections.

The conclusion: more is not always better – and in fact, overextending treatment can do harm by fuelling unnecessary resistance

This is a striking parallel to the modern content cadence. More emails, more posts, and more noise rarely lead to better outcomes.

The problem isn’t technology – it’s trust. Overuse of automation has conditioned audiences to tune out, not lean in, proving that more communication doesn’t equal more connection.

Even brand storytelling, once hailed as the cornerstone of connection, is showing diminishing returns when executed formulaically.

Research from Sprout Social (2024)[iv] found that engagement with “founder story” content declined by nearly 30% year-on-year – a clear sign that familiarity, when overused, breeds resistance rather than resonance.

The brands that win in this next era will be those that practise marketing stewardship – showing up with precision, not volume alone.

Time for Marketing Stewardship

Medicine eventually learned that the solution wasn’t “more antibiotics.” It was antibiotic stewardship – using them only when truly needed, and with precision.

New drugs alone can’t fix a broken relationship with the medicine; what’s required is discernment, restraint, and responsibility in how we use what already works

In the same way, we don’t need endless new tactics – we need discernment, and stewardship. We need to use our tools wisely, intentionally, and in ways that restore the health of our audience relationships rather than deplete them.

Attention stewardship means treating audience attention as sacred, not disposable. It’s knowing when to speak and when to stay silent. It’s recognising that just because you canautomate doesn’t mean you should.

With generative AI now enabling mass content production, digital ecosystems are showing early signs of “content resistance.” Content velocity has increased, but effectiveness has plateaued, signalling an ecosystem out of balance.

Instead of accelerating output, we need to architect ecosystems where communication aligns with purpose, timing, and trust.

Because in a system overloaded with content, more activity doesn’t equal more visibility – it simply accelerates entropy.

Purpose ensures that what we share actually matters.
Timing ensures it lands when it’s most relevant.
And trust ensures that it’s received in the spirit it was intended.

When these three elements work together, communication becomes regenerative rather than extractive.
It nourishes the ecosystem instead of draining it.
It restores the natural rhythm between message and meaning – and that’s the foundation for healing both the brand and the broader marketing environment.

This shift reflects the broader movement toward ethical, sustainable, and human-centred marketing – principles embedded in the AMI’s Code of Professional Conduct[v] and AMI’s Marketing Competency Framework.[vi]

 

Understanding Systemic Resistance

Before exploring what this means for the next era of marketing, it’s worth reflecting on what the World Health Organization (WHO) identifies as the real-world consequences of resistance.

The WHO warns that antibiotic resistance threatens the very foundation of modern healthcare. Procedures once considered routine – from surgery to chemotherapy – are at risk because the antibiotics designed to prevent infection are becoming less effective.

The organisation calls this a “silent pandemic” that undermines trust in medical systems and demands urgent global cooperation.[vii]

When antibiotics lose their power, it’s not just the bacteria that change – the system does.

Hospitals start operating under strain. Doctors hesitate to prescribe. Patients begin to worry that the medicine might not work next time. That quiet erosion of confidence ripples outward, shaking the foundation of trust that holds modern medicine together.

According to the WHO, antimicrobial resistance threatens “the very foundation of healthcare,” because it destabilises what people have always relied on – the assumption that medicine will heal, that professionals can protect, that systems are safe.

Once that trust falters, every interaction carries more fear and less faith.

The same thing happens in marketing.

When Marketing Loses Trust

When audiences stop trusting the systems meant to serve them –  whether hospitals or brands – the whole ecosystem weakens.

In medicine, that shows up as antibiotic resistance; in marketing, it shows up as attention resistance. People stop opening emails, stop reading blogs, stop believing promises, stop feeling seen.

Edelman’s 2024 Trust Barometer[viii] reports that public trust in business communications has fallen to 59%, the lowest in a decade. The decline isn’t due to lack of reach – it’s due to perceived inauthenticity. The audience, like an immune system, has learned to detect what’s synthetic.

The erosion of trust hasn’t happened all at once – it’s crept up on us slowly, through small moments of overreach. Too many “personalised” messages that aren’t personal. Too many “authentic” stories that feel rehearsed. Too many quick fixes sold as transformations.

And just like overprescribed antibiotics, each misused marketing tactic chips away at the health of the system.

Over time, audiences develop antibodies against manipulation.

They learn to filter, to scroll past, to disengage. Even well-intentioned brands feel the effects, because once collective trust declines, everyone’s messages land softer. The whole environment becomes resistant.

The cure isn’t more persuasion – it’s rebuilding relational integrity.

Relational integrity – the ability to sustain trust through consistent, ethical engagement – is what allows brands to rebuild credibility at scale.

In medicine, it means using treatments responsibly, communicating transparently, and prioritising the patient’s wellbeing over speed or convenience.

In marketing, it means communicating with honesty, pacing, and respect. It’s remembering that attention is not a right to be taken – it’s a privilege to be earned.

The antidote to marketing fatigue isn’t more marketing. It’s strategic context – and disciplined nuance.

Next Practice: Marketing in an Age of Saturation.

When integrity is restored, eventually the system will begin to heal itself.
The same mechanisms that once spread resistance start spreading trust.

But the reality is that most people wearing the marketing hat in their business – particularly those who are self-taught or overly focused on tactics at the expense of strategic nuance – will continue to rely on inherited tactics: the ones they’ve seen, been taught, or believe still work.

Add to that the endless stream of new platforms, tools, and apps promising effortless success, and it’s clear that the glut of formulaic marketing isn’t going away soon. If anything, it will intensify before it corrects.

So what’s next practice in an environment where best practice no longer hits the mark?

These three principles offer a blueprint for thoughtful marketing in an age of saturation.

1. Hold the Line on Standards.
   Stay anchored in evidence, ethics, and clarity. When others chase quick wins, model long-term strategy and professional integrity. People are watching, and they notice what consistency and credibility look like in action.
2. Design for Discernment.
   In a market flooded with content, precision becomes a differentiator. Be selective about when, where, and how you show up – and ensure that every touchpoint carries meaning and intention.
3. Re-Humanise the Experience.
   Technology can scale reach, but only humanity sustains relevance. The marketers who preserve empathy, nuance, and creativity will outlast the noise. True creativity is becoming scarce as automation replaces originality; those who keep imagination alive will hold a decisive advantage.

Systemic change will come eventually – but thoughtful marketers don’t wait for the system to change; they lead the change by practising it.

The Future Belongs to Thoughtful Marketers

This is not just a communications challenge; it’s a systems challenge – and the marketers who recognise that will lead the next era.

The marketers who will define the next decade won’t be the loudest voices or the highest content producers – they’ll be the most discerning, creative and integrous.

They’ll recognise that the era of volume equating to visibility is well and truly over. Attention is now a finite and fragile resource, and treating it carelessly carries systemic consequences, much like the overuse of antibiotics in medicine.

They’ll understand that genuine influence cannot be automated.
That scale without substance undermines credibility.
And that the leaders who thrive will be those who use technology to amplify human intelligence and empathy, not replace it.

The discipline of marketing is entering its stewardship era –  one defined by precision, restraint, and relational integrity.

Sustainable growth will depend on our ability to rebuild trust in the system itself: to use data responsibly, create meaningfully, and communicate with clarity and care.

Because when the cure becomes the cause, progress depends on discernment.

It’s not about doing more; it’s about doing what matters – with insight, integrity, and intention.

That’s how we create brands that will shape the future.
