The observer effect describes a simple idea: the act of observation changes what is being observed.

Although this concept is generally applied to natural and behavioural science, I think it’s surprisingly relevant to content marketing.

Think about it.

If systems behave differently when they’re being watched, maybe content behaves differently when it’s being measured.

Is it possible that the more rigorously we measure content performance – clicks, engagement rates, impressions, time on page, and so on – the more radically the act of measurement shapes the way content is conceived, written, and published?

In other words, maybe metrics aren’t just evaluating content anymore – they’re shaping it, and not always for the better.

In this post, I’m going to explain why I think metrics are changing the way content is built, why this isn’t necessarily something to celebrate, and why writing for readers, not dashboards, will always produce better results.

The observer effect explained

The observer effect is pretty simple. Essentially, it’s an idea that can be broken down into four constituent elements:

1. Measurement requires interaction.
2. Interaction changes state.
3. The greater the sensitivity, the greater the disturbance.
4. The more closely you measure, the greater the influence.

You can see this pattern play out time and time again across a wide range of fields.

Take something really simple, like measuring temperature.

You might assume that such a straightforward process would be immune to the observer effect, but in fact, inserting a thermometer into a small system (for example, tiny liquid samples) can change its temperature through heat transfer.

In other words, the act of measurement (inserting a thermometer) changes what’s being measured (temperature).

Outside of science, another great example of the observer effect in action is the use of time-tracking software to measure worker productivity.

If workers are aware that their keyboard activity or logged hours are being tracked, they’ll likely optimise their time to prioritise visible effort so that they appear active or busy. Focusing on measurable tasks may correlate with a rise in apparent productivity, but it can also lead to an avoidance of unobservable “thinking” work.

Therefore, as a direct result of productivity being observed, deep strategic thinking – which could be more beneficial in the long run – declines.

But what does all of this have to do with content marketing? Let’s take a look.

How metrics came to dominate content marketing

Before the widespread use of analytics in content marketing, content was judged on slower, more qualitative signals.

For example, a client might mention in a meeting that a recent market update reassured them during a period of volatility, while a prospective customer may claim that a particular article helped to clarify a recurring question, prompting them to get in touch.

Essentially, content wasn’t regarded so much as a product to be optimised, but a tool to support understanding and trust. To that end, feedback was more likely to be received indirectly, rather than in the form of immediate, quantified data, and one could infer success not from clicks or impressions, but from outcomes like smoother decision-making and long-term client retention.

In recent years, however, there’s been an inexorable march toward the use of analytics, dashboards, and platform reporting in content marketing. Using these tools, firms can examine precisely how content performs through a wide range of metrics, including open rates, click-through rates, engagement metrics, SEO rankings, and social shares.

Although this type of visibility promises objectivity and accountability, an overreliance on metrics to determine the efficacy of your content can be detrimental.

How metrics shape what gets written

As soon as content performance became measurable, content marketers began changing how they produced it. This was a completely rational response to the insights generated by metrics, and many of the changes that ensued were entirely understandable.

For instance:

• If shorter articles reduced the bounce rate, articles would get shorter.
• If market commentary attracted traffic during volatility, volatility would become a publishing trigger.
• If bold claims increased engagement, headlines would become sharper and language would become more confident.

However, over time, dashboards began to dominate the content production process. Metrics were no longer diagnostic, but directive. This led to a range of second-order effects that have meaningfully shaped the way content is produced, and not for the better.

Here are some of the most significant of these effects:

1. The prevalence of safe topics

Content about safe, digestible topics (for example, “5 ways to reduce tax”) is always likely to outperform more in-depth explorations of complex estate planning or compounding interest.

Consequently, the priorities of content marketers skew towards these kinds of topics, rather than more thorny pieces that could have long-term, strategic importance.

For example, as intelligent as modern dashboards are, they can’t measure whether an article prevented a client from making a poor investment decision five years into the future.

2. Nuance disappears

When it comes to financial advice, things are rarely simple.

Almost every topic you can think of involves some form of uncertainty. From caveats and trade-offs to the inherent complexity of human behaviour, nuance is a key part of responsible financial content.

But unfortunately, this type of nuanced explanation is virtually always outperformed by strong, simple statements characterised by black-and-white thinking, so that’s what content marketers produce, despite the fact that in many cases, clients actively want a more greyscale approach.

3. The erosion of professional judgement

Perhaps the most insidious second-order effect of the primacy of metrics to the content production process relates to the way in which content marketers begin to internalise what “performs” over what is actually “useful”.

This leads to content that prioritises strong opinions, certainty, and attention-grabbing commentary at the expense of complexity and caution.

4. Shifting audience expectations

The end result of all this is that audiences are essentially conditioned to expect quick and definitive answers. But in many cases, good financial advice is neither of those things.

When confronted with the restraint and proportionality that is so often a hallmark of responsible advice, clients who are accustomed to the clarity and brevity provided by content overly influenced by metrics may feel shortchanged.

Why this matters

So, let’s get down to brass tacks: why does this actually matter?

After all, is it really the end of the world if you have to sacrifice a little bit of substance to attract more visitors to your website? At the end of the day, content is content; it’s not as if you’re compromising the integrity of the advice you’re providing, is it?

Well, there are a couple of reasons to be concerned.

Firstly, it’s important to remember that engagement and trust are not the same thing. Metrics tend to measure surface behaviour, not long-term cognitive impact. Shares don’t necessarily equate to trust, clicks don’t always correspond to agreement, and time on page may not map to understanding.

In many cases, the best and most useful content that financial advisers can produce is actually fairly boring – for example, a mailer urging calm in the wake of market volatility, or an article clarifying that in many cases, doing nothing is the best way to deal with dips in your investment portfolio. Dashboards don’t capture the value of this type of content, which is why they can often be so misleading regarding the type of articles that they incentivise content marketers to produce.

It’s also important to remember the specific guardrails that the financial advice profession has to deal with. While all industries can be affected by the observer effect, the type of content that is generally privileged by metrics can be particularly ill suited to financial planning firms.

Advisers have long-term client relationships, regulatory frameworks, and fiduciary duties to consider. In this context, oversimplification and exaggeration isn’t just a stylistic choice, but a route to interpretative risk, potentially exposing firms to genuine compliance issues that can have an enormous impact on client confidence.

Another point to consider is the fact that the observer effect essentially inculcates your content production cycle into a feedback loop:

1. Measurement-driven content performs well.
2. Similar content is produced.
3. Content becomes more homogenised.
4. Audience expectations narrow.
5. Content that is innovative, cautionary, or offers a viewpoint that is contrary to the prevailing consensus becomes “risky”.
6. The concept of what constitutes “good” financial content is warped to fit the standards of what performs well for dashboards.
7. Over time, authority declines as financial advice firms move away from sober analysis and towards more generic digital content.

So, as a self-reinforcing closed system, the content production cycle optimises for what it is able to measure. While the short-term metrics may improve, over the long term, the perceived authority of the financial advice firms that produce this kind of content falls away. The audience no longer looks to you for good judgement and valuable insight, but for quick-fire hot takes and snappy certitudes.

Writing for readers, not dashboards

The problem isn’t with the concept of metrics and performance tracking itself. Fundamentally, dashboards are just tools, and metrics do have enormous value if used correctly (for example, to understand basic reader behaviour, diagnose distribution problems, and so on).

The issue is that all too often, content marketers have allowed metrics to become invisible editors of the work they produce. The solution, ultimately, is to go back to basics and ask a fundamental question: what is good financial content? In our view, it’s content that:

• Reduces anxiety
• Reinforces long-term thinking
• Strengthens understanding.

Articles that produce these outcomes aren’t likely to be a big hit on your dashboard, but over time, they compound knowledge and trust. Remember, if financial advice can be boiled down to a single principle, it’s the value of good judgement under uncertainty, and your content should be an extension of that principle. Measuring too closely risks distorting the qualities that make advice valuable in the first place – the patience, nuance, and restraint that characterises decisive financial advice.
