Serial Position Effect: Why Only First & Last Matter

We’ve all been told the same thing about writing.

“Pack your copy with detail.”
“Make it complete.”
“Fill the gaps.”

That’s the lie.

Because the human brain doesn’t work like that. We don’t hold onto every word. We don’t store every bullet point. We only remember the beginning and the end. The middle? It vanishes.


​This is the Serial Position Effect. And if you’re not building around it, you’re wasting words.

I used to cram everything into my sales pages.
Every feature. Every angle. Every little detail.

I thought I was being thorough.

Smart. Professional.

But when I tested those pages, they bombed.

Nobody remembered the list of features.
Nobody cared about the clever sentences in paragraph six.

What they did remember?

My first line. And my closing call-to-action.

That’s when I realized: the middle is a swamp. Attention dies there.

So I started writing differently. Shorter. Sharper. And focused only on two spots: the hook and the close.

Here’s how you flip the script.

1. Lead with a Pattern Break

Your first line must snap attention. Ask a blunt question. Drop a bold claim. Break the pattern they expect. If you don’t stop them at the start, you never get another chance.

2. Make the Middle a Bridge

Stop bloating the middle. It’s not the show. It’s the walkway from hook to close. Keep it lean, keep it clear, and never hide your best lines there.

3. Close Like a Closer

Your last line decides if they act. Don’t whisper. Don’t thank them politely. Command action. Paint the future. Make it impossible to forget.

4. Bookend with Proof

Open with authority. Close with results. People remember those anchors. Everything else is just noise.

We’ve built a culture of copywriting that worships the middle.

The endless features.
The stacked bullet points.
The corporate jargon that nobody reads.

But ask yourself: when was the last time you remembered the fourth bullet on a sales page? When was the last time you quoted the middle of a blog post to a friend?

You didn’t.

So why are you still writing like people care? Why are you protecting your ego instead of protecting your sales?

Here’s the law: If they don’t remember your first line and your last line, you don’t exist.

That’s it. Forget the middle. Nobody cares. Nobody remembers.

Hook them early. Close them strong.
Build your business on the only words that matter.

Because in the end, your copy isn’t a lecture. It’s a fight for memory.

And only the sharpest lines survive.
