Latest / The Copywriting Podcast with Fexingo: Sales Letters, Headlines, and Persuasive Writing / The Psychology of Copywriting Friction
Transcript
- Lucas: Most people think good copy has to be effortless. You see that advice everywhere: keep it simple, use short sentences, make it skim-friendly. But I’ve been looking at some older direct response archives from the late nineties, and the most effective sales letters weren’t just easy to read—they were slightly hard. They demanded a little more effort from you, and that extra millisecond of cognitive load was exactly what made them convert. Luna: Wait, so you’re saying if I make my customers work harder, they’ll buy more? That feels completely counterintuitive to everything we’ve learned about user experience over the last decade. Lucas: It does feel wrong. But there’s a specific psychological mechanism here called cognitive fluency. When something is too easy, our brain assumes it’s trivial or low-value. By introducing a small amount of friction—whether through denser text, a less common font, or a more complex sentence structure—you signal that this information matters. It forces the reader to engage rather than just scroll past. Luna: So it’s like the difference between a quick snack and a gourmet meal. If it’s too fast, you assume it’s junk food. But surely there’s a limit? We can’t just start writing in dense academic prose. Lucas: Exactly. The key is intentionality. It’s not about making it unreadable; it’s about removing the passive consumption mode. Think about high-ticket consulting offers or complex financial products. Nobody buys those on impulse because they skimmed a bullet point. They buy because they read, processed, and convinced themselves. The friction acts as a filter for serious buyers. Luna: I remember seeing an A/B test where a landing page used a slightly smaller font size and it outperformed the default by twelve percent. I assumed it was a glitch, but maybe it was this exact principle kicking in. Lucas: That sounds plausible. There was a famous study involving a difficult to read font versus a standard one. People who read the difficult version actually retained more information and trusted the claims more, provided the message itself was strong. The difficulty wasn’t in the words, but in the visual presentation. It signaled seriousness. Luna: But isn’t that risky? What if the customer gets frustrated and bounces instead of buying? Where do you draw the line between interesting friction and annoying obstruction? Lucas: You draw the line at clarity of intent. If the product is complex, the copy should reflect that complexity without being confusing. For example, a software integration guide needs precision, which might require longer sentences and technical terms. But a headline still needs to be punchy. The friction goes in the body, not the hook. Luna: So the hook invites them in with ease, and then the body slows them down to build value? That makes sense. It’s like slowing the car down once you’re already inside. Lucas: Precisely. And this ties into the broader concept of commitment. Once someone invests time reading your copy, they are psychologically committed to finishing it. That’s the endowment effect in action. They’ve already paid the cost of attention, so they’re more likely to pay the cost of purchase to justify that investment. Luna: I love that framing. It turns reading time into equity. But how do you apply this to email marketing? Emails are supposed to be quick reads. Lucas: In email, the friction is often structural. Instead of a three-sentence summary, you write a full story. You use paragraphs that break the pattern of typical newsletters. You force the reader to scroll further. That scroll is the friction. It filters out the casual scrollers and leaves the engaged readers who are more likely to click. Luna: So longer emails can actually have higher conversion rates for certain audiences? I’ve always been told to keep emails under two hundred words. Lucas: That rule applies to mass market, low-cost items. For high-value offers, length correlates with sales. Look at the classic Direct Response legends. Their emails were often thousands of words long. They didn’t care if only ten percent of subscribers finished it. Those ten percent were their best customers. Luna: That’s a bold gamble. Betting on quality of engagement over quantity of clicks. It requires a lot of confidence in the offer. Lucas: It does. And it requires knowing your audience. If your audience is busy professionals, they don’t mind spending five minutes reading a detailed analysis. If your audience is scrolling on TikTok, they won’t. The context dictates the level of acceptable friction. Luna: Right. Context is king. So if I’m selling a $200 course to project managers, I can afford to be dense. But if I’m selling a $5 app, I need to be instant. Lucas: Spot on. The price point determines the threshold. Higher prices demand higher justification. Justification takes space. Space takes time. Time creates friction. It’s a chain reaction that works in your favor if the product delivers. Luna: This is really changing how I view readability scores. I usually try to lower them, but now I’m wondering if raising them slightly might help my premium clients. Lucas: Try it. Take one piece of copy and deliberately complicate the syntax. Use more subordinate clauses. Remove some transition words. See if the perceived value goes up. You might be surprised by how much weight heavy words carry. Luna: I will. But Lucas, what about accessibility? Making copy harder to read can exclude people with dyslexia or other learning differences. Isn’t that unethical? Lucas: That is a critical point. Accessibility is non-negotiable. Friction should never mean illegibility or exclusion. The goal is cognitive engagement, not visual struggle. You can increase intellectual depth without sacrificing clear typography or plain language principles. It’s about the ideas being complex, not the words being obscure. Luna: Okay, so complexity of thought, not complexity of form. That’s a crucial distinction. We want to challenge the mind, not blind the eye. Lucas: Exactly. And that brings us to a moment where I want to pause and talk about how this show stays ad-free. If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Luna: Yeah, if these conversations have sparked something you've actually used, consider supporting the network directly. It keeps the research deep and the ads out. Lucas: Thanks for listening. Now, back to the copy. Let’s look at a specific case study from a fintech company that struggled with sign-ups. Luna: I remember reading about that. They had a great product but low conversion. What did they change? Lucas: They rewrote their landing page hero section. Originally, it was three bullet points explaining features. Very clean, very easy. Conversion was stuck at one percent. They changed it to a single paragraph that explained the problem in detail, using precise numbers and industry-specific jargon. Luna: Wow. They added friction by using jargon? That sounds dangerous. Lucas: It was risky, but the jargon acted as a badge of insider knowledge. It signaled that this tool was built by experts for experts. The conversion rate jumped to four percent overnight. The friction filtered out the casual browsers and attracted the serious traders. Luna: So the friction worked as a trust signal. It said, 'We know you’re smart, so here’s the real data.' Lucas: Yes. And it respected the reader’s intelligence. Too many brands treat their customers like children, simplifying everything until it’s meaningless. Adding friction says, 'We respect you enough to give you the details.' Luna: That’s a powerful reframe. Simplicity isn’t always respect. Sometimes detail is the highest form of respect. Lucas: Precisely. So next time you’re reviewing your copy, ask yourself: is this too easy? Is it possible that by making it effortless, you’re accidentally signaling that it’s worthless? Luna: I’m going to go back and add a little bit of weight to my latest draft. Maybe a few longer sentences. Lucas: Do it. And let me know if the conversions move. We’re all curious to see how far you can push the friction before it breaks. Luna: Deal. Thanks, Lucas. This has been a weirdly compelling take on simplicity. Lucas: Anytime, Luna. Keep writing, keep testing, and keep respecting your reader’s time—and their ability to handle complexity.
