I ordered food at KFC today.

That shouldn't be a memorable experience.

But I left thinking less about the food and more about the touchscreen.

I grew up in a small town.

I don't regularly use airport check-in kiosks.
Self-checkout counters.
Touchscreen ordering systems.

I understand how they work.

But I still need a minute.

Not because they're difficult.

Because they're unfamiliar.

So I walked up to the kiosk and started reading the screen.

I wanted to figure it out on my own.

Before I got very far, an employee walked over.

"Can I help?"

It was a kind gesture.

He was only doing his job.

But my immediate reaction wasn't relief.

It was discomfort.

I wanted him to leave.

Not because I didn't appreciate the help.

Because I wanted the freedom to make mistakes privately.

That surprised me.

I wasn't afraid of pressing the wrong button.

I was afraid of someone watching me press the wrong button.

There's a difference.

We don't mind learning.

We mind learning in public.

It made me think about something else.

Why do so many people prefer texting over calling?

We usually say it's more convenient.

Or that it's less intrusive.

I think there's another reason.

Texting gives us privacy.

Not privacy from the other person.

Privacy from our unfinished thoughts.

When I text someone, I can pause.

Rewrite a sentence.
Delete half of it.
Change my mind.
Think for a minute.

The other person only sees the final version.

They never see the messy process that produced it.

The conversation is edited before it's shared.

Phone calls don't work that way.

Every pause is heard.

Every hesitation exists.

Every unfinished sentence becomes part of the conversation.

You're thinking while communicating.

Not before it.

The KFC kiosk felt the same.

Until someone stood beside me, the interface felt private.

I could read slowly.

Compare meals.
Tap the wrong button.
Go back.
Change my mind.

The moment another person watched me, it stopped feeling like a conversation with a machine.

It became a performance.

We often think of privacy as protecting information.

Passwords.
Photos.
Messages.
Payment details.

But I think there's another kind of privacy that deserves more attention.

The privacy to learn.

The privacy to hesitate.

The privacy to make mistakes.

Good interfaces don't just reduce cognitive load.

They reduce social pressure.

They create enough space for people to be temporarily confused.

Without feeling incompetent.

As designers, we measure everything.

Clicks.
Conversion rates.
Completion times.

We celebrate interfaces that help people move faster.

Maybe we're measuring the wrong thing.

Maybe we should also ask:

Does this interface give people permission to think?

The best interfaces I've used don't make me feel intelligent.

They make it safe to not know.

They let me explore without feeling observed.

They remind me that learning doesn't always need an audience.

Sometimes the greatest kindness an interface can offer isn't speed.

It's privacy.
