I was recently invited by Perkins Coie—one of the most respected litigation firms in the country—to join their Persuasion Occasion podcast.

We covered a wide range of topics on jury decision-making, trial strategy, and persuasion.

But one idea stood out—because it runs directly against how most lawyers are trained to think:

“Fear wins. When fear is up against logic, fear wins.”

If you try cases for a living, that statement should matter to you.

Because it explains why strong, logical cases sometimes lose—and why weaker cases sometimes win.

The Problem with the “Rational Jury” Model

Lawyers are trained to believe that juries are rational decision-makers.

We’re taught to:

• Build logical arguments
• Present evidence clearly
• Establish causation step-by-step
• Trust that the “better case” will prevail

That model is clean.

It’s also incomplete.

As I explained during the conversation with the litigation team at Perkins Coie:

“Humans are susceptible to being influenced by fear… it’s well known, it’s well understood.”

Jurors are not logic processors.

They are human beings making a consequential decision under uncertainty.

What Jurors Are Actually Doing

When jurors deliberate, they are not simply asking:

• Who made the better argument?
• Which expert was more credible?

They are asking something much more fundamental:

• What happens if we get this wrong?
• Is there risk in this verdict?
• Will this decision lead to harm?

That’s not logic.

That’s risk assessment driven by emotion—specifically, fear.

Why Fear Is So Powerful in Jury Decision-Making

Fear has a structural advantage over logic.

• Logic requires certainty
• Fear requires only doubt

A juror doesn’t need to be fully persuaded by the opposing side.

They just need to feel uncomfortable.

Once that happens, even a well-constructed, evidence-based argument can lose traction.

This is why fear-based narratives—whether explicit or subtle—play such a central role in trial outcomes.

The Reality of Trial Strategy

This isn’t theoretical.

It’s something trial lawyers confront every day.

As I noted in the discussion:

“We will use it in trial when that tool is available to us.”

And particularly in certain plaintiff strategies:

“We’ll play up the scary role… we will use the reptile strategy.”

That’s not criticism—it’s acknowledgment.

Fear is already present in most cases:

• Fear of future harm
• Fear of repeated conduct
• Fear of systemic risk

The question is not whether fear exists.

The question is whether you’ve addressed it.

Where Defense Teams Often Go Wrong

One of the most common strategic mistakes—especially in complex litigation—is over-reliance on logic.

Defense teams often assume:

• If causation is weak → they’re safe
• If the facts are strong → they’ll win

But jurors don’t evaluate cases like judges.

They evaluate comfort.

If a juror feels even a small amount of unresolved risk, that discomfort can override otherwise strong legal arguments.

A Better Framework for Persuasion

Instead of asking:

“How do we prove our case?”

A more effective question is:

“What is the juror afraid of—and have we addressed it?”

That shift changes everything.

Because once fear is:

• Acknowledged
• Contained
• Reframed

…jurors become far more receptive to logic.

This Isn’t About Manipulating Juries

It’s important to be clear about this.

Recognizing the role of fear is not about exploiting it.

It’s about understanding how decisions are actually made.

Effective advocates:

• Identify perceived risks
• Address them directly
• Give jurors a reason to feel confident in their verdict

When you do that, you’re not replacing logic.

You’re creating the conditions where logic can finally work.

Final Thought

You can have:

• The better facts
• The stronger expert
• The more logical argument

And still lose.

Because juries don’t decide cases in a purely logical framework.

They decide them in the presence of uncertainty.

And in that environment:

Fear doesn’t just influence the verdict.
It often determines it.
