Why Your Brain Only Remembers Two Moments of Any Experience

Hi there,

I arrived in Positano and the owner is waiting at the gate with cold lemonade. She remembers I mentioned I love hiking, so she's already mapped out all the best trails, all the ones with the most breathtaking lookout points.

There were bikes lined up by the porch, each fitted with water, sunscreen, a hand-drawn village map. The kitchen is stocked with fresh Italian lemons, local honey, and fresh bread. That first evening on the terrace, the sun melted into the cliffs. Everything was perfect.

Three days later, I'm packing to leave. The owner appears with a bill. Not for the rental but for "incidental damages” for coffee mug I'd broken (couldn’t have been more than five dollars, max). But her tone shifted; she was suddenly curt and transactional. A week later, someone asks how the trip was. I don't describe three perfect days. I describe the ambush at checkout.

People Actually Prefer More Pain…?

It's maddening, really. You have an amazing overall experience, but our memory only selects the peak & end to catalogue the experience. Psychologists call this duration neglect.

Daniel Kahneman and Donald Redelmeier demonstrated this beautifully in a study involving colonoscopies (which, yes, is as uncomfortable as it sounds). They found something counterintuitive: patients who endured longer procedures but with gradually easing discomfort at the end rated the overall experience as less painful than those with shorter procedures that ended abruptly.

It was the same procedure but participants had a different memory and experience

Why? Because memory judges experiences by their peak and their end. Kahneman calls this the "Peak-End Rule," and it explains everything from why a terrible movie with an amazing twist feels worth watching, to why one awkward interaction at the end of an otherwise great day ruins the whole thing.

Your experiencing self (the part of you living through the moment) was there for all 3 days in Positano. But your remembering self (the part that tells the story later) only cares about those two moments.

Endings Stick & Define the Experience

I watched this play out in a pitch meeting at work not long ago. A vendor came in with an exceptional deck, confident speaker, the whole room was leaning in. For 45 minutes, they nailed it. The energy was high. People were taking notes. This was going to be a yes.

Then came the Q&A.

Someone asked a hard question, a reasonable one about scalability. And the speaker got defensive. Their tone tightened. They stopped listening and started arguing. For 10 minutes, they quietly undid 45 minutes of trust.

We didn't hire them.

A month later, I realized I couldn't tell you a single thing about their presentation. What I remembered was the defensive energy in that Q&A. That's the story we remember when someone asks about them.

The presentation was a 45-minute masterpiece. The ending was a 10-minute disaster. And the ending was what stuck.

Peaks & Endings Carry Equal Weight

The thing is that peaks matter just as much as endings. But endings are easier to control. You can't always control a peak, that's often circumstantial, dependent on others, or just... the universe doing what it wants. But you can almost always design how something ends. That's where your power lives.

The Positano owner created a genuine peak… the thoughtful hikes, the cold lemonade, the hand-drawn map. She just forgot about the ending. And five dollars worth of curt energy erased three days of magic.

The vendor created a peak too. Polished, confident, compelling. They just couldn't hold it through the hard questions. Ten minutes of defensiveness wrote off 45 minutes of brilliance.

This isn't unfair. It's just how memory works. And once you know it, you can use it.

How to Use This

You can't control how people remember everything. But you can control the peak and the end. And those two moments carry disproportionate weight in how the entire experience gets remembered.

In presentations: Most speakers spend 80% of prep time perfecting the middle, then trail off at the end like they just remembered they left the stove on. Spend 10 deliberate minutes designing your final 90 seconds instead. Write them down. Practice them. Make the last thing they hear the thing you most want them to remember.

In difficult conversations: Arguments don't get remembered by their substance — they get remembered by how they end. You can be right, articulate, and mature for 20 minutes, and one defensive parting shot rewrites the whole thing. A genuine "I value you and I want to get this right" costs nothing. But it's the last thing the remembering self records.

In relationships (personal and professional): Your client remembers the final handoff. Your team remembers the last piece of feedback. Your partner remembers the fight that ended badly, not the hundred quiet days that came before it.

Make it count.

One last thing…

Before any major interaction, a presentation, a difficult conversation, a client or team meeting, ask yourself one question:

What's the last thing they'll feel or hear from me?

Then design it thoughtfully.

The Positano owner gave me three perfect days. She just forgot that the last five minutes would rewrite all of them.

Because endings are what gets remembered.

Your focus shapes your reality. Shift it.
