Why Good Evidence Beats Good Writing

A well-written technical narrative reads convincingly. It flows, it sounds confident, and on first read it can be genuinely persuasive. None of that matters much if the evidence behind it isn't there, and I think this is one of the most misunderstood parts of preparing an R&D claim.

Persuasive Isn't the Same as True

Writing quality and evidence quality are different things, and it's entirely possible to have plenty of one without much of the other. A narrative can be beautifully written and still be thin on genuine substance, describing uncertainty in general terms without actually demonstrating it happened. HMRC has seen enough of that pattern to recognise it quickly.

Good evidence does something writing alone can't. It shows, rather than simply states, that a genuine uncertainty existed and that specific people worked through it in a specific way. Design documentation, test results, meeting notes, source code history, even the emails discussing a problem as it was happening, all carry a kind of weight that no amount of skilled writing can substitute for.

Where This Actually Shows Up in Practice

The claims that hold up best under scrutiny don't have to be the most elegantly written. They're the ones where the evidence and the narrative say exactly the same thing, because the narrative was built from the evidence rather than the other way around.

That also means the competent professional's input matters more than most people expect. Their explanation of why something was genuinely uncertain, given in their own words and properly documented, is often stronger evidence than any amount of polished prose written on their behalf afterwards.

What This Means for How We Work

We treat evidence gathering as the foundation of a claim, not something layered on top once the narrative is drafted. If the evidence isn't there, no amount of good writing fixes that, and I'd rather have that conversation early than let a claim rely on writing quality to carry weight it can't actually support.

Good writing still matters. A clear, well-organised narrative makes evidence easier to follow and easier to trust. But it's a container for the evidence, not a replacement for it.
