The Black Butterfly Effect

When I was building my first business, my Japanese mentor told me to keep an eye out for black butterflies.

“If you ever see a black butterfly,” she said, “it is a sign of good things coming your way.”

Until that moment, I never noticed a single one. But after she planted that idea in my head I started seeing them everywhere.

I’d spot a black butterfly fluttering around the train station, dancing in the trees, and weaving between cars during rush hour.

WTF? Was this… black magic?

Despite being young, dumb, and hungry for success, I knew these black butterflies weren’t spawning out of thin air.

They were always there, hidden in the background noise of my everyday life.

What my business mentor did do was change my internal radar. She tuned my mind to look for them, and, when spotted, I’d associate them with good things to come.

I also happened to be living in a small, industrial town called Shunan in Yamaguchi-ken where tens of thousands of these black butterflies exist. So, she knew exactly what she was doing to help me focus on building a successful business in a foreign land (ありがとう, Saseko!).

You’ve Likely Experienced This Yourself

I’m referring to the Baader-Meinhof Phenomenon, also known as the Frequency Illusion.

a cognitive bias where you notice a new word, object, or idea everywhere after just learning about it (even though its actual occurrence hasn’t changed).

A common example is when you start shopping for a new car, and, let’s say you’re considering the new 2026 Toyota RAV4.

Thanks to me, you’re now going to see them everywhere you go.

• Look—there’s a Toyota RAV4 stopped next to you at a red light.
• Wow—there’s dozens at the Walmart parking lot.
• Wait—did Steve, who lives 7 houses down, always have one? Huh!

(Yoo-hoo, Toyota! If you’re reading this, can I get an affiliate link please? Or maybe a job with your marketing team somewhere in Japan?)

The Frequency Illusion in Copywriting

When marketers hear about the Baader-Meinhof effect, their first instinct is to:

1. Fire up Meta Ads Manager

2. Drop a pixel on a landing page, and

3. Blast prospects with 50 retargeting impressions a day.

They try to brute-force the illusion through sheer volume, hoping that seeing a logo seven times before breakfast makes a brand feel "everywhere."

Smart copywriters, like you and I, know it doesn’t work that way.

You can’t manufacture frequency through ad spend because relentless retargeting doesn’t build a belief—it just creates ad fatigue.

Instead, a great copywriter manufactures meaning.

And right now, in your ideal buyer’s world, there are 1000s of black butterflies all around them.

Maybe not real butterflies but unnamed annoyances, quiet micro-frustrations, and hidden desires. They have daily experiences that don't have a label yet their brain filters them out as irrelevant noise.

Your job as a copywriter is to name their butterfly.

The moment you give a prospect's vague, messy problem a hyper-specific name or framework, two things happen:

1. You flip their selective attention switch. Their brain registers the new concept. Then, every time that problem happens in their day, it jumps into focus.

2. You attach an emotion to the experience. Just like the butterfly triggered optimism and good fortune for me, recognizing the problem you named triggers a reaction: "That's exactly what I'm dealing with."

In other words, you’re now playing with two cognitive engines that work in your favor.

Those cognitive engines are:

1. Selective Attention: When the brain identifies a novel word, problem, or concept and puts it on a radar screen.

2. Confirmation Bias: Every time you see it again, it becomes "proof" that it is suddenly everywhere.

Let’s look at a couple of examples to inspire you.

A Historic & A Modern "Butterfly" Campaign

Claude Hopkins & Pepsodent "The Film"

Before the 1920s, barely anyone in America brushed their teeth daily (which is f***ing nasty). Toothpaste was a slow-selling product because people didn't see dental hygiene as an urgent problem.

Then legendary copywriter Claude Hopkins stepped in.

He didn't write ads saying "Brush your teeth every day." Instead, he gave people a physical prompt to look for. He told readers to run their tongue over their teeth:

"Run your tongue across your teeth. You’ll feel a film. That’s what makes your teeth look dull and invites decay."

By calling it "The Film," Hopkins planted a black butterfly. The moment a reader closed the newspaper, they couldn't help but run their tongue over their teeth. And, that’s right, “The Film“ was EVERYWHERE.

Within a decade, national toothpaste usage exploded from 7% to over 65%.

Naming the "Inbox Zero" & "Context Switching"

This strategy isn't reserved for black-and-white print ads. Even the best modern B2B tech companies use it constantly.

For example:

• Slack didn't sell team chat. They named "Context Switching"—that exhausting feeling of jumping between 12 browser tabs, losing your place every 5 minutes. Now, every time a remote worker feels brain fatigue at 2:00 PM, they recognize the butterfly Slack named.

• Merlin Mann didn't sell email management. He named "Inbox Zero." The moment that phrase took root, every unread notification number became a visual nuisance demanding resolution.

How Will You Name Your Prospect's Butterfly?

If you want to pull this off in your own sales pages, emails, or content, run your offer through this simple transformation matrix:

Generic problem (ignored noise)	The named butterfly (selective trigger)	The daily real-life trigger
“Low sales email responses”	“The Inbox Graveyard”	Hitting ‘Send’ and staring at a silent screen
“Feeling tired at work”	“The 3 PM Sugar Crash”	Looking at the office clock after lunch
“Bad client boundaries”	“Scope Creep”	Getting a “quick question” text at 8 PM

When you coin the phrase, you don't just explain a feature. You give your prospect a pair of glasses—and once they put them on, they can't unsee the butterflies.

Your Responsibility as a Writer

When my mentor pointed out those black butterflies, she wasn’t selling me anything. She gave me a sense of hope and direction—a mental compass that made me pay attention to the good things waiting in my background.

That is the true power of a copywriter.

Anyone with a credit card and an Ads Manager account can buy up screen space to annoy a prospect into submission. It takes no talent to turn yourself into a digital mosquito buzzing in someone's ear.

To name the butterfly, however, requires deep empathy.

It requires you to:

1. Sit with your reader's daily reality,

2. Pay attention to the micro-frustrations they haven't found the words for yet, and

3. Hand them a vocabulary that makes sense of their chaos.

When you do it right, you don't just win their attention for thirty seconds on a feed. You rent a permanent place in their mind.

So—stop paying Mark Zuckerberg to chase your audience around the internet and start inspiring people to spot the black butterflies inside their heads.

To your success in business (and life),

p.s. Even now—a decade after building and selling my business in Japan—I still smile and believe luck is coming my way when I spot a black butterfly.

p.p.s. Seriously, Toyota! My family builds the RAV4 at the manufacturing plant in Cambridge. I also followed your brand guidelines to create the image at the start of this letter. So, if your marketing department is hiring, let’s talk.
