- Lucas: So we talk a lot on this show about tools for career reflection — brag files, values stacks, energy audits. But there is one practice I keep coming back to that we have never covered in depth, and it might be the most practical one of all: a career decision log. Luna: A decision log. You mean like a journal where you write down the big calls you make at work and then look back at them later? Lucas: Exactly that. It sounds simple, maybe even obvious, but the research on it is striking. There is a well-known study from the journal Judgment and Decision Making — they tracked professionals across consulting, engineering, and medicine — and found that people who kept a structured decision log improved their decision accuracy by about 30 percent over two years compared to a control group that didn't. Luna: Thirty percent is a huge edge. Especially in a career context where one bad move can set you back six months or more. Lucas: Right. And the mechanism is straightforward: you are forcing yourself to surface your own reasoning before you know the outcome. That makes it much harder to rewrite history later — you know, the classic 'I knew that was a bad idea all along' bias. Luna: Hindsight bias is real. I have definitely told myself I saw a failure coming when I absolutely did not. Lucas: Everyone does. So let me give a concrete example. Imagine a marketing manager at a mid-size consumer goods company. She is offered a lateral move to lead marketing for a new product line — plant-based snacks. It is a hot category but the brand is tiny, the budget is thin, and her current role is stable with a good team. Luna: Classic career fork in the road. Do you go for the growth opportunity or stay in the safe lane? Lucas: Exactly. So she opens her decision log — could be a simple spreadsheet, a notebook, whatever — and writes down the context: the offer details, what she knows about the new category. Then she lists her reasoning: on one hand, she wants to build expertise in a high-growth area; on the other, she is worried about job security because the parent company has a history of cutting underperforming brands. Luna: And she records her expected outcome — what does she think will happen if she takes it? Lucas: She writes: 'I expect that within 18 months, the new brand will either reach profitability or be shut down. If it survives, I will have a strong story about turning around a business. If it fails, I will have wasted a year and maybe hurt my reputation.' She ends up declining the offer. Nine months later, the parent company divests the entire plant-based division. Luna: So she looks smart in hindsight. But the real value is that she can later review her log and see that her reasoning was sound — she weighed the risk correctly, she didn't just go with her gut. That builds confidence in her own judgment over time. Lucas: That is the whole point. The log is not about being right or wrong. It is about calibrating your internal decision-making compass. When you review a log after six months, you start to see patterns — maybe you are systematically overestimating how long projects will take, or you tend to favor safe options even when the upside of a risk is much larger. Luna: I find that especially true with career decisions. We tend to anchor on salary or title, but the decision log can reveal that what actually made you happy in the past was autonomy or learning — something you didn't even list as a factor at the time. Lucas: Which is the second big benefit: it surfaces the criteria you actually use versus the ones you think you use. I have a friend who is a product leader — she started keeping a log three years ago. She told me she realized that in seven out of ten job offers she declined, the primary reason was 'culture fit,' but she had never once written that down. She would list compensation, growth potential, commute — and then the real reason was something squishier she didn't capture. Luna: So the log forces honesty. And that honesty can be uncomfortable — but it is the only way to improve. Lucas: Before we go further, I want to mention something. This show is ad-free and listener-supported, and the reason we can keep doing episodes like this — diving into practical tools rather than chasing clickbait — is that some listeners choose to chip in a few dollars a month. If you have gotten value from the show, especially if a specific episode helped you think through a career decision, you can support it at buy me a coffee dot com slash fexingo. It genuinely makes a difference. Luna: Yeah, and it keeps the show independent. No sponsors, no pressure to hype things we don't believe in. We really appreciate that. Lucas: So back to the log. The key is structure. You do not need to write a diary entry. I recommend three columns: context — what is the situation, what are the options; reasoning — what are your pros and cons, what assumptions are you making; and expected outcome — what do you think will happen and by when. Luna: And you should log within 48 hours of making the decision, before the outcome bias kicks in. The moment you know the result, your memory of your original reasoning starts to warp. Lucas: Exactly. I also add a fourth column sometimes: 'mood' — just one word, like anxious, excited, or conflicted. Because your emotional state at the time of a decision is a data point too. If you notice you always make riskier calls when you are frustrated, that is useful information. Luna: That is a good one. I once made a career move out of frustration with a boss — I was angry, and I took a job that looked great on paper but was actually a terrible fit. A log would have caught that pattern. Lucas: Right. So let's talk about the review process. The log is useless if you never revisit it. I recommend a quarterly review — set aside 30 minutes, look at the last three months of entries. For each decision, ask: did the outcome match my expectation? If not, why? Was my reasoning flawed, or was it just bad luck? Luna: And that is where you start to see your blind spots. Maybe you are too optimistic about timelines. Or you consistently underestimate how much you value work-life balance until you are in a role that demands 60-hour weeks. Lucas: There is also a fascinating phenomenon called 'decision fatigue' that the log can reveal. If you see that your decisions later in the day or late in the week are systematically worse — more impulsive, less thorough — that is a sign to schedule your big calls for mornings or Tuesdays. Luna: I read a study about judges — their parole decisions dropped sharply as the day went on. Same thing can happen with career moves. Lucas: Exactly. So the log is not just retrospective. It becomes a tool for designing better decision-making conditions. You start to ask: what time of day am I clearest? What kind of decisions do I tend to rush? Who should I consult before I decide? Luna: And it is free. You can start today with a Google Doc. No special app needed. Lucas: One more thing: share your log with a trusted mentor or peer. Not the raw entries necessarily, but the patterns. Let someone else look at your decision history and tell you what they see. External perspective is incredibly valuable for catching biases you are blind to. Luna: That is a great idea. I might start doing that with a former colleague. We already do a monthly check-in, but this would give it more structure. Lucas: So to wrap up: a career decision log is a simple, low-effort habit that compounds over time. Three columns, quarterly reviews, and a willingness to be honest with yourself. It won't make every decision perfect, but it will make you better at learning from the ones that don't work out. Luna: And that learning is what separates people who keep making the same mistakes from those who steadily improve their professional judgment. Lucas: Exactly. So if you are not already logging your decisions, try it for one quarter. See what you discover.
