The Power of Costly Signalling (or, How Cookies Got a Guy Hired)

Your message is only as strong as how you deliver it. Just ask Julian (and his famous cookies).

The Power of Costly Signalling (or, How Cookies Got a Guy Hired)

We like to believe that the quality of our work speaks for itself. That if we have the right skills and experience, or offer the best product, people will naturally take notice.

But here’s the kicker: how you deliver your message matters just as much as the message itself.

This is where the Costly Signalling Theory comes in.

At its core, costly signalling is about proving value through effort. The more time, energy, or resources you put into sending a message, the more people perceive that message as important. Think of it like a peacock’s tail. Totally impractical, but a clear sign to potential mates (or in our case, employers and clients) that the peacock has resources to spare.

Rory Sutherland puts it best in his book Alchemy (which you should totally read):

The meaning and significance we attach to something is felt in direct proportion to the expense with which it is communicated.

In other words, the harder you work to get someone’s attention, the more they assume you must be worth paying attention to.

Now, let me tell you a story about how one guy used this principle to land his dream job with a little creativity, some bold moves, and, of course, cookies.

The Julian Playbook

Someone I care about a lot—let’s call him Julian—wanted to break into the world of design. The problem? He had zero professional experience, just a few short courses under his belt, and a personal training job that paid less than $500 (R8,000) a month.

Like many job seekers, he was stuck in the soul-crushing cycle of mass-applying to every listing on LinkedIn, uploading his CV to every recruitment database, and waiting for… well, nothing.

I had some deep conversations with Julian, and one thing became clear: he was optimising for the wrong thing. He didn’t need a job; he needed interviews.

So we threw the traditional playbook out the window and tried something completely different.

The 3-Step Plan

I told Julian he’d change his life in three months if he followed this plan. (Spoiler: It took four, but who’s counting?)

  1. Make a hit list. Find 15 design agencies he’d love to work for, track down their office addresses, and get the name of the CEO.
  2. Get personal. Design a custom-printed CV for each agency, and get some cookies made with fun, design-related messages on them.
  3. Go full old-school. Hand-deliver the CV and cookies directly to each CEO. No emails, no job portals. Just showing up, making an impression, and proving he was worth noticing.

The result?

The Famous Cookies That Got Him Noticed

Within weeks, Julian had seven interviews and two job offers.

By making his outreach costly in time, effort, and creativity, he signalled that he wasn’t just another faceless CV in a pile. He showed initiative, personality, and a willingness to go the extra mile.

Why This Works (and How You Can Use It)

Every time you put in extra effort to engage with someone, you’re increasing the perceived value of that communication.

Think about it:

  • A generic cold email? Meh.
  • A personalised message with a thoughtful reference? Better.
  • A handwritten note, a well-chosen gift, or an in-person visit? Now you’re getting somewhere.

Most of us delete marketing emails without a second thought. But a package that lands on your desk? That gets attention.

There’s something about a physical object that makes it feel more intentional. When someone goes out of their way to send a well-thought-out package, a handwritten note, or even a small surprise, it immediately stands out.

It shows effort. And effort makes an impression.

So here’s your challenge:

Find one deal in your pipeline that’s stalling and level up your next message. Make it costlier. Add a little effort, creativity, or personal touch. You might be surprised at the results.

And if all else fails… try cookies. 🍪
