There are many habits worth cultivating in life—staying physically fit, meditating and reading regularly. However, they rarely produce visible results overnight. Instead, they demand small, consistent investments of time and discipline. Yet, as with compounding in finance, these seemingly insignificant actions accumulate to yield extraordinary long-term returns.

 

A good book doesn't simply add information; it changes how you think. My recent read, Thinking in Bets by Annie Duke, a former professional poker player turned decision scientist, offered a profound lesson for investors: in an uncertain world, success depends on making consistently good decisions.

 

 

Visual summary: Thinking in Bets, by Annie Duke

 

 

We live in a poker economy, overflowing with information but starved of certainty. Investors are bombarded with earnings releases, economic indicators, AI-generated forecasts, geopolitical developments, and endless market commentary. Every headline seems capable of moving markets, creating the illusion that successful investing requires correctly predicting every interest-rate decision, election, or earnings surprise.

 

 

History tells a different story. Markets have never been predictable with precision; they have only been manageable through probabilities. Investing is fundamentally a game of incomplete information, uncertain outcomes, and, yes, luck. You can make a well-researched investment and still lose money in the short run. Equally, an uninformed gamble may occasionally pay off. The challenge is learning to judge decisions independently of their immediate outcomes.

 

 

Duke calls our biggest mental trap "resulting," evaluating a decision solely by its outcome rather than by the quality of the reasoning behind it. When investments succeed, we credit our skill. When they fail, we assume the analysis was flawed. Both conclusions are often wrong. This tendency fuels several behavioral biases familiar to investors.

 

 

Outcome bias leads us to judge yesterday's decisions using today's prices. Hindsight bias leads us to believe that major market events were obvious in retrospect. In contrast, recency bias tempts us to extrapolate the latest trends indefinitely. Together, these biases encourage investors to mistake short-term noise for meaningful information and frequently abandon sound strategies at precisely the wrong time.

 

 

Howard Marks makes a similar observation in The Most Important Thing. In investing, he argues, outcomes alone are poor measures of decision quality because markets are inherently probabilistic. A good process can produce a disappointing outcome, just as a poor process can occasionally produce a windfall. Over thousands of investment decisions, however, disciplined processes tend to outperform lucky guesses.

 

 

Consider the early months of the COVID-19 pandemic. Investors who owned diversified portfolios and remained disciplined experienced severe short-term losses despite following sound investment principles. Many who abandoned their plans in panic locked in those losses, while those who stayed invested eventually benefited from one of the strongest market recoveries in history. The process had been sound even though the immediate outcome was painful.

 

 

 

 

If ‘resulting’ is the trap, systems thinking is a large part of the way out. Peter Senge's The Fifth Discipline, a management classic, argues that most poor decisions arise from focusing on isolated events rather than the structures that generate them. Financial markets are classic complex adaptive systems. A central bank's rate hike, for example, affects far more than borrowing costs. It influences consumer spending, housing demand, business investment, inflation expectations, bond yields, sector leadership, capital flows, and ultimately investor psychology. The most important consequences are often the second- and third-order effects that unfold months later, not the headline itself.

 

 

Understanding systems also requires recognising that markets do not merely respond to reality, they help create it. This is the essence of George Soros's theory of reflexivity, one of the most powerful yet under appreciated ideas in investing. Prices influence expectations, expectations influence behaviour, and behaviour changes economic reality itself. Markets do not simply reflect reality; they shape it. Rising prices attract more buyers, pushing prices even higher and reinforcing optimism while influencing corporate behavior. Expectations become part of reality itself. Asset bubbles and market crashes are often the product of these self-reinforcing feedback loops. Understanding reflexivity reminds us that fundamentals and market sentiment are not separate forces; they continuously influence each other.

 

 

Duke teaches us to judge decisions by process rather than outcomes. This does not mean outcomes are irrelevant. A single investment result reveals little about the quality of a decision because luck always plays a role. However, repeated poor outcomes over time may indicate flaws in the underlying process. The objective is not to ignore results but to evaluate them across enough observations for skill to emerge from randomness. Peter Senge reminds us to look beyond headlines and understand the underlying systems driving markets. George Soros shows that investor expectations themselves become part of those systems. Successful investing, therefore, requires building a robust decision-making framework that can survive uncertainty.

 

 

My dear readers,

 

• Ask five simple questions whenever a major event occurs:
  • What has actually changed?
  • Who is directly affected?
  • How will those participants respond?
  • Who are the second-order winners and losers?
  • What expectations has the market already priced in?

 

• Maintain a decision journal. Record your assumptions before making major investment decisions so that future evaluations focus on process rather than outcomes.

 

• Size positions prudently. Never risk too much on a single idea, no matter how compelling it appears.

 

• Accept "bad beats." Even excellent investments occasionally fail because of unforeseen events. That is the cost of participating in uncertain markets.

 

• Judge performance across full market cycles, not individual quarters. Time allows probability and disciplined processes to work in your favor.

 

"Is my investment process robust enough to survive when my forecast is wrong?"

 

Remember, in both investing, life and poker, we cannot control the cards we are dealt. We can only control how consistently and intelligently we choose to play them. Disciplined habits compound not only wealth, but also judgment, knowledge and character. What disciplined habits do is increase the probability that when an opportunity appears, we are prepared to seize it. It is vital to recognise that probabilities themselves evolve.

 

Probabilistic thinking is not about clinging stubbornly to an initial view; it is about continuously updating one's beliefs as new evidence emerges. That is the essence of Bayesian thinking. In an uncertain world, success belongs not to those who predict perfectly, but to those who learn, adapt and improve their decisions over time.
