Latest / The Marketing Career Podcast with Fexingo: Marketing Jobs, Skills, and Career Growth / How Marketers Build a Decision Journal
Transcript
- Lucas: We spend a lot of time talking about tools, platforms, and metrics in marketing. But there is one thing that separates senior directors from the rest of the pack, and it isn't just experience. It is the ability to evaluate your own judgment. Luna: Right, because anyone can get lucky with a viral post. The real skill is knowing why it worked so you can do it again without luck. Lucas: Exactly. And most marketers never do that review. They look at the result, feel good or bad, and move on. But if you want to build actual expertise, you need to separate the quality of the decision from the quality of the outcome. Luna: That sounds like a classic case of outcome bias. We judge the choice by what happened, not by what we knew when we made it. Lucas: Spot on. So today we are talking about the Decision Journal. It is a practice borrowed from high-stakes fields like investing and military operations, but it applies perfectly to marketing strategy. You write down your reasoning before you act. Luna: So you document the why, not just the what? Lucas: Precisely. When you are about to make a significant call—like launching a new product line, hiring for a key role, or pivoting your content strategy—you pause and write three things. First, the context. What problem are you trying to solve? Second, the alternatives you considered and why you rejected them. Third, your specific expectation of the outcome. Luna: That last part is crucial. Most people just say they expect it to work. Being specific forces you to think through the mechanics. Lucas: It does. Let me give you a concrete example. Imagine a brand manager at a mid-sized consumer goods company. They have to decide whether to invest heavily in influencer marketing or stick with traditional search ads. They write down that they chose influencers because engagement rates are higher in their demographic, even though the cost per acquisition is unknown. Luna: Okay, so they record that assumption. Then what happens six months later? Lucas: Six months later, the campaign flops. The cost per acquisition was terrible. Without a journal, the manager might just conclude that influencers don't work for their brand. But with the journal, they can go back and see that their assumption about engagement translating to sales was flawed. They didn't account for audience mismatch. Luna: So the journal turns a failure into data. It stops you from throwing the baby out with the bathwater. Lucas: Exactly. It reveals the root cause. Maybe the influencers were right, but the landing page was broken. Or maybe the target audience was wrong. Without writing it down, you only remember the headline number. With the journal, you remember the logic. Luna: This reminds me of how investors use journals. They track their thesis over years. It builds a very different kind of confidence than just guessing right. Lucas: It does. And for a marketer, this is a massive career accelerator. When you walk into a performance review, you aren't just listing successes. You are demonstrating a mature understanding of risk and uncertainty. That is executive-level thinking. Luna: I love that. It shifts the narrative from I got lucky to I know how I think. Lucas: Before we dive deeper into how to actually structure these entries, I want to mention something quick.

Luna: Yeah, really appreciate that. It helps us keep the signal to noise ratio high. Lucas: Let's get back to the mechanics. The biggest mistake people make with Decision Journals is being too vague. Vague entries are useless six months later. You need specificity. Luna: Like what counts as vague versus specific? Lucas: Vague is: I think this video will go viral because it's funny. Specific is: I believe this video will drive traffic because our audience engages heavily with humor-based storytelling on Tuesdays, and the hook addresses their main pain point about time management. Luna: The second one gives you a testable hypothesis. The first one is just hope. Lucas: Exactly. And you should also record your emotional state. Were you anxious? Overconfident? Rushed by a deadline? Emotions skew judgment, and acknowledging that helps you calibrate next time. Luna: That's a hard one to admit. Admitting you were rushed feels like admitting fault. Lucas: It feels like fault, but it's actually data. If you notice that eighty percent of your bad decisions happen when you are rushed, then you have identified a process flaw. You start protecting your decision time differently. Luna: So it becomes a personal operating system update. Lucas: Yes. Now, how often should you review these? Weekly is good for tactical stuff, like email subject lines or small ad spends. Quarterly is better for big strategic bets, like entering a new market or rebranding. Luna: Quarterly makes sense. You need enough distance to see if the original logic held up or if the world changed. Lucas: Right. And during that review, be honest. If you were wrong, write down why. Did you miss information? Did you misinterpret the data? Or did you ignore red flags because you wanted the deal to close? Luna: The last one is the killer. Confirmation bias is everywhere in marketing. We love our ideas. Lucas: We do. We fall in love with the creative or the channel. The journal acts as a cold mirror. It forces you to look at the raw facts of your initial reasoning. Luna: Does this work for team settings too? Or is it purely individual? Lucas: It works beautifully for teams, but it requires psychological safety. If your boss punishes you for having a different opinion recorded in writing, the journal won't help. It needs to be a safe space for intellectual honesty. Luna: That's a cultural issue, not a tactical one. A leader who demands this is asking for vulnerability. Lucas: It is. And that leader earns trust faster. Because everyone knows you aren't hiding behind hindsight. You are showing your work. Luna: I can see how this would change how my team operates. Less finger-pointing, more learning. Lucas: Absolutely. And here is a practical tip. Start small. Don't try to journal every single tweet or social post. Pick one major decision per month. One campaign launch, one vendor selection, one hiring decision. Luna: Quality over quantity. Keep it manageable so you actually stick with it. Lucas: Yes. Consistency beats intensity. If you do one thoughtful entry a month, you will have twelve data points a year. That is enough to spot patterns in your own thinking. Luna: Twelve data points. That's a lot more reliable than memory alone. Lucas: Memory is a storyteller. It edits out the doubts and amplifies the successes. The journal is the archivist. It keeps the truth intact. Luna: I like that metaphor. We need archivists in our heads, not just storytellers. Lucas: So, if you take one thing away from this, it is this: Before your next big move, stop and write it down. Capture the context, the alternatives, and the expectation. Then wait for reality to catch up. Luna: And when it does, compare the map to the territory. See where you drifted. Lucas: Exactly. It is a slow game, but the compounding returns on your own judgment are immense. You become less reactive and more intentional. Luna: Intentionality is the ultimate career asset. Everything else is just tactics. Lucas: Well said. I wonder what other cognitive traps we could expose with this same method. Luna: Probably plenty. But starting with the journal is a great place to begin untangling them.
