You’re Afraid of Public Speaking, But Do You Know Why?

I taught a public speaking class for business professionals at Emory University for fifteen years. You know what I learned?

Most people fear public speaking more than anything—including spiders, heights, and even death.

Yes, you read that right. The average person would rather die than give a speech.

But here’s what’s even more surprising: most people don’t know why they’re so afraid. I’ve asked hundreds of people and when I do, they vaguely mention a fear of being judged. That’s true, but it doesn’t fully explain why the fear is so paralyzing.

Okay, so people might judge you. So what?

The real reason public speaking feels like life or death is because, subconsciously, we equate it with survival.

Let me explain.

In early human history, survival depended on being part of a group. We relied on each other for food, protection, and resources. If two people got into a conflict and one was banished from the tribe, how long do you think that person would survive on their own?

Being cast out meant death.

We are genetically hard-wired to fear the rejection of our peers.

So when you’re about to give a presentation, your brain plays out a worst-case scenario:

Mess up → Lose credibility → No promotion → Financial struggle → Can’t afford food → Starvation → Death.

Logically, we know a bad speech won’t kill us. But our reptilian brain doesn’t see the difference.

Here’s the good news: We’re also wired for connection.

Humans are built to help each other. Every presentation, at its core, is meant to serve—whether you’re selling a product or reporting quarterly earnings, someone is supposed to benefit from what you’re saying.

So instead of focusing on fear, focus on helping.

Try this: Choose a low-stakes presentation. Write down the key takeaway—how will your talk make life easier or better for your audience?

Then watch what happens to your fear. It will still be there, but it won’t be in control. You will.
