Metacognition
The Hidden Skill of Superior Investors
Managing real capital exposed a simple truth, judgment fails before analysis does. The solution: a metacognitive framework for decision-making.
As eternal students of investing, we’re always looking to improve our decision-making process. When starting out, the focus was naturally on the analytical toolkit—understanding basic accounting and finance, analyzing financial statements, studying business models, and practicing valuation techniques. But after years of managing real capital through multiple market cycles, it becomes clear there’s a more foundational element that’s often ignored: the ability to recognize your own thinking processes and regulate your decisions accordingly.
This skill is metacognition: the practice of bringing awareness to our own thinking. Over time, it may be the most important capability an investor can develop.
Habitual tendencies drive our behavior more than we would like to admit. Most discussions of habit focus on physical behavior—checking your phone at breakfast for example. But our deepest habits are cognitive ones. How we interpret information, the patterns we default to under stress, the narratives we construct to explain uncertainty—these mental habits shape every investment decision we make. Left unexamined, these habits begin to operate automatically, outside of conscious awareness.
The Metacognitive Framework
Our framework operates on two dimensions. First, knowledge about cognition: understanding your own mental blind spots in real-world decision-making. An investor might recognize, for instance, their tendency toward narrative seduction, overweighting a compelling story regardless of quantitative concerns. Second, regulation of cognition: the ability to monitor and adjust thought processes in real-time. This is the ability to notice when emotional reasoning has overtaken analysis, or when confirmation bias is filtering incoming information. Consider the investor watching a position drop by 50%. Can they distinguish fear-based loss aversion from rational business judgment? That distinction is impossible without metacognitive awareness.
Research in behavioral finance demonstrates that metacognitive ability directly influences decision-making quality across domains. Markets, by their very nature, demand decisions under ambiguity. Metacognitive investors acknowledge this reality explicitly, not defensively. They build systems to compensate for known limitations and remain alert to psychological states that compromise judgment.
Metacognition isn’t about achieving perfect rationality—it’s about developing honest awareness of cognitive tendencies and creating systems to work with human psychology rather than attempting to eliminate it. It also allows for greater clarity to emerge within the thinking process itself. In markets where most available information is already priced in, durable advantage increasingly comes not from more data, but from seeing it more clearly.
That advantage begins with knowing yourself.
How We Apply Metacognition in Practice:
Decision Journaling
Document the reasoning and conviction behind each buy/sell decision. This creates an audit trail that reveals patterns in thinking over time. When reviewing past decisions, we’ve noticed our highest-conviction purchases made during periods of market pessimism (StoneCo during their 2023 credit business collapse and Alphabet during AI competitive concerns), consistently outperformed impulsive additions during bull markets. This pattern awareness now triggers a metacognitive pause: Am I buying because the opportunity is exceptional, or because recent gains have made me overconfident?
Examine Emotions Before Acting
Every decision has an emotional component—excitement, calmness, urgency. These feelings are diagnostic. Excitement often signals narrative seduction: we’re attracted to the story rather than present value. Urgency suggests FOMO or anchoring to recent price action. Calmness paired with grounded conviction often signals genuine mispricing.
In late 2024, we watched as our Alibaba stock fell by roughly 30%. During a drastic drawdown in a core holding, a natural thought arises: What if we’re wrong? This scenario requires reassessing the investment thesis and valuation. It is possible that the thesis has structurally deteriorated. Selling solely due to a rapid decline—before completing the analysis—would have been a metacognitive failure.
Establish Falsifiable Metrics
Define the investment thesis using actionable and trackable data points. If results consistently fall short of expectations, continuing to hold could reflect ego-based attachment rather than rational analysis. Our Clorox thesis relies heavily on operational improvements through ERP benefits. For example, we are tracking fill rates, market share, and gross margin thresholds that would break our thesis if they were violated. This creates valuation guardrails that reduce the risk of cognitive bias.
Metacognition transforms investing from a reactive, data-driven exercise into a disciplined, self-aware practice. By understanding how we think, we navigate uncertainty more skillfully, mitigate behavioral errors, and develop the subtle edge that separates superior investors from everyone else.
These principles inform everything we publish, including our recently released Q4 2025 Letter, where we discussed the concentrated value positions that contributed to our 67.5% annual return. These letters remain free and are intended to be transparent records of our thinking.
Newsletter Update
Beginning February 2026, we’re introducing paid content for readers who want deeper access to our work. This will include in-depth earnings reviews for portfolio companies, new investment cases, and detailed financial models outlining our valuation methodology. Our quarterly letters will continue to remain free.
We’re grateful to share this journey with you and welcome feedback on how we can continue to improve the quality and value of this work.

Strong piece on the decision journaling framework. The falsifiable metrics approach is critical but most investors skip it becuase it forces uncomfortable accountability. What I've found is that defining those threshold levels upfront creates discipline but the harder part is actually executing the sell when thresholds break. Ego protection kicks in and suddenly the metrics seem less relevant. The Alibaba example is textbook metacognition done right.
