The Actuary’s Secret to Writing a Blog That Actually Works

Blogging

When people think of actuaries they picture someone quiet in a room, creating spreadsheets the size of cathedrals and thinking about death — specifically, about how to price it. Which isn't, on the face of it, anything to do with blogging about your coffee roastery or your plumbing business. However, the core idea that makes actuarial science work is the same idea that makes blogging work. Once you understand this core idea, it changes how you think about the whole thing.

The Bit Where Someone Dies Unexpectedly (Bear With It)

Here’s the fundamental problem for life insurers. They are selling a policy to someone who might die in two years or might die in forty-five. They have no idea which it will be. What they are selling to is ten thousand people, all at the same time, and across a population that large, the uncertainty about any individual simply collapses into something remarkably predictable. The maths irons it out. The book of business, as they call it, behaves sensibly even when individual cases do not.

No underwriter sits awake worrying that a particular policyholder is going to die young and cost them money. That is the whole point: you do not manage your exposure policy by policy. You manage the portfolio.

Your Blog Is a Portfolio, Not a Gamble

Blogging not working is the usual conclusion when a single blog post goes nowhere. We sell one life policy and the person lives to ninety-four – does that mean the whole business model is broken?

The post that goes nowhere is not the unit of analysis. The body of work is.

Each article you publish is a small bet. It’s a claim that someone, somewhere, will one day search for exactly this, or share it, or stumble across it and send it to a friend. Any individual bet might pay off immediately. It might sit quietly for three years before finding its moment, or never quite land. But you’re not placing one bet here. You’re building a book. Fifty articles is a proper portfolio. Five is a coin toss.

This is why the advice to "just keep writing" is not motivational fluff. It is the same cold logic an actuary uses when they insist on a long data series before they will price anything. Short series lie. Long series tell you something real.

Why Consistency Is the Underwriter's Friend

Actuaries are obsessive about data quality, and particularly about gaps. A gap in the data – a year where records were not kept, a cohort that was excluded – degrades the whole model. You cannot simply average around a missing chunk and pretend it isn't there. The integrity of the series matters.

Blogging has exactly the same vulnerability. A site that published reliably for two years and then went quiet for eight months has a gap in its series, and readers feel it even if they couldn't articulate why. The trust that accumulates with a regular publishing rhythm compounds quietly, like interest. Lose it once and you don't just pause – you partially reset.

This is not an argument for burning yourself out. Actuaries do not price every policy at the same premium regardless of cost — they are precise about what they can sustainably carry. Setting a blogging pace you can actually maintain beats an ambitious sprint followed by silence every single time.

The Post That Never Pays Off

The cold truth that actuaries are comfortable with but bloggers tend to find upsetting is that some individual policies will be loss-making. Not because the underwriting was wrong, but because risk is risk. The book works as a whole, but individual entries within it are allowed to underperform.

Some of your posts will find almost nobody. Others will feel like your best work and disappear without a trace. But the actuary doesn't conclude from this that the whole enterprise is doomed. He looks at how the portfolio is performing over time, adjusts the model where the data suggests it, and carries on pricing.

This is the only sane response, really. You wrote the thing. It's in the book. Now write another.

A post that "failed" by any immediate measure – no shares, no traffic spike, barely a flicker on the analytics – is still part of the book. Still a policy in force. You simply do not know yet which one is going to pay out.

FAQ

Does one blog post that goes nowhere mean blogging doesn’t work?

We can’t judge by a single post that goes nowhere. It’s the whole body of work that matters. Each article is a small bet. They can immediately bring results, they can sit quietly for three years or they can never bring any results at all. It’s only after a while that we can judge the entire array of posts.

How many blog posts do you need before it starts working?

Fifty articles represent a good portfolio while five articles represent a coin toss. A short data series is misleading while a long data series reveals something real. That’s why “just keep writing” is not empty motivational fluff but good advice, for the bigger body of your posts will yield more reliable results.

Does publishing consistently really matter for a blog?

Consistency matters to your readers. A site that posts reliably for two years and then doesn’t post for eight months has a gap in its series. Trust builds up slowly like interest, and losing it means a partial reset, starting to build up trust with your readers again. Post at a rate that you can sustain in the long term rather than posting at a high frequency for a short period of time and then falling silent.

What should I do with a blog post that gets no traffic?

No, I would keep all of your writing even if it got no shares or traffic. You can’t tell yet which of them will be good for you. It’s best to look at the performance of your entire portfolio over time and make changes based on your data. Keep writing!
