The Science-based Playbook of Ad Creatives by Science Says by Thomas McKinlay: is it worth buying?

You’re staring at a blank creative canvas, and the only voice in your head is a mix of agency folklore, a viral TikTok, and whatever the last designer on your team swore by. You know the fundamentals, but you’re tired of guessing which font actually stops the scroll or whether a person pointing at the product outperforms a clean product shot. That’s exactly the gap The Science-based Playbook of Ad Creatives is built to close. Instead of handing you another opinion-based checklist, Thomas McKinlay distills over a thousand pages of academic research into a 43-page PDF that tells you what the data actually says about visual hierarchy, copy, and layout. It’s not a beginner’s course on how to open Canva; it’s a high-signal reference for the specific decisions that make or break a campaign’s performance.

Quick answer

What you’re actually buying

At $59, you aren’t just buying a PDF; you are buying a shortcut past the $2,000 worth of academic journals and 1,000+ pages of dense research that Thomas McKinlay has already read and synthesized. The core of the offer is a set of 58 specific creative recommendations, each tied to a scientific finding. These aren’t vague platitudes like “use high contrast”; they are precise directives on what to say, which colors to pair with specific product types, and how to position a human subject to maximize attention.

The structure is designed for speed. Each insight is broken into bite-sized chunks, meaning you can open the ad creatives playbook before a design review, find the section on video scripts or font styles, and walk into the meeting with a data-backed argument. It covers the full spectrum of creative decisions: from the optimal spacing and layout of a static image to the specific words that capture attention in the first two seconds of a video. You get examples of how to apply these insights, so you can move from theory to execution in minutes rather than hours.

This is where the product earns its price tag. Most “ad guide” ebooks are 200 pages of fluff, 90% of which is recycled marketing advice. This one is 43 pages of pure signal. One buyer, a UX content designer, noted that they use it as a reference for creative roles across marketing, praising how the “bite size chunks of easy-to-comprehend tips” make it usable in real-time workflows. Gumroad reviews back this up, with one user noting they “just started reading but already loved it” due to the clarity of the presentation.

Why it’s on our radar

The market is flooded with “creative optimization” guides, but almost all of them rely on anecdotal evidence or the author’s personal success stories. This playbook stands out because it explicitly rejects opinion in favor of peer-reviewed science. It’s a rare find in the digital product space to see a seller position their product as an alternative to “self-proclaimed experts,” grounding every recommendation in actual research papers.

For a $59 price point, the density of value is high. You are getting a condensed version of a significant research effort, packaged in a format that a creative team can actually use. It’s not a subscription service or a complex tool; it’s a static, high-quality reference document that you can keep on your desktop and consult whenever you’re stuck on a creative decision. The 30-day money-back guarantee also lowers the risk, allowing you to verify that the recommendations align with your specific product category before you commit.

What actually matters

Before you buy, make sure you are at the right stage of your creative journey. This is an advanced optimization tool, not a foundation course. If you don’t yet understand what a CTR is or how to set up a basic ad campaign, this PDF will feel like a foreign language. It assumes you know the mechanics of ads and are looking to refine the creative elements to squeeze out better performance. (The Science-based Playbook of Ad Creatives)

Second, check if your product type is well-represented in the examples. While the science is universal, the application of colors, fonts, and human subjects can vary wildly between a B2B SaaS tool and a fast-fashion clothing brand. The 58 creative recommendations cover a broad range, but you should skim the table of contents or the preview to ensure the specific ad types you use (static, video, carousel) are thoroughly addressed.

Finally, remember that this is a guide, not a guarantee. The seller is transparent about this: ads crafted with these principles are optimized to perform better, but they are not guaranteed to succeed. You should still use A/B testing and pre-testing platforms. Think of this playbook as your hypothesis generator—it gives you the best possible starting points based on science, but you still need to let the market data confirm which variant wins.
