Life outcomes depend on two factors: luck and decision quality. Only one is controllable. Most people cannot articulate what constitutes a sound decision process, despite making thousands of choices daily. This gap exists because decision-making rarely features in formal education. Even experienced executives rely on intuitive methods rather than systematic frameworks.

Published in 2020, How to Decide synthesises decades of research from behavioural economics, cognitive psychology, and decision science into accessible frameworks for general audiences. The work arrives amid growing recognition that systematic cognitive biases undermine judgment quality across…
The most pervasive obstacle to learning from experience is the tendency to judge decision quality by outcomes rather than process. This cognitive shortcut, termed resulting, creates a misleading feedback loop that reinforces poor practices whilst punishing sound reasoning when luck intervenes…
Every decision opens pathways to multiple possible futures, not a single predetermined outcome. Understanding this multiplicity fundamentally changes how people should evaluate choices. Rather than seeking certainty about which option is correct, effective decision-makers assess which alternative…
Sound decision-making requires explicit consideration of three elements: preferences (what matters personally), payoffs (how much each outcome matters), and probabilities (how likely each outcome appears). This framework transforms vague deliberation into structured analysis that improves choice…
Thorough decision-making improves outcomes, but exhaustive analysis carries costs. Time spent deliberating has opportunity costs. Excessive deliberation creates stress. Perfectionism prevents action even when good-enough options exist. Knowing when to decide quickly versus when to invest time…
Positive visualisation dominates self-help advice: imagine success, maintain optimism, focus on goals. Whilst motivation matters, exclusively positive thinking creates dangerous blind spots. Systematically considering how plans might fail reveals obstacles, enables contingency planning, and improves…
Life quality depends fundamentally on two factors: luck and decision quality. Whilst fortune remains beyond control, improving choices represents the sole mechanism for shaping outcomes. Yet remarkably few people can articulate what constitutes sound decision-making, despite making thousands of…
Most people evaluate decisions based on outcomes rather than process quality. This cognitive shortcut, termed resulting, creates systematic errors in learning from experience. When asked to identify their best and worst decisions from the past year, people typically describe their best and worst…
Hindsight bias compounds resulting's problems by distorting memory of what was known before outcomes occurred. After events unfold, people misremember their prior uncertainty, convincing themselves that results seemed obvious or inevitable when they actually appeared ambiguous beforehand. This…
Every decision opens pathways to multiple possible futures rather than a single predetermined outcome. This decision multiverse concept fundamentally reframes how people should evaluate choices and learn from experience. Understanding that outcomes represent one realisation amongst many…
Systematic decision-making requires explicit structure rather than vague deliberation. The six-step framework centres on three core elements (the Three Ps): preferences, payoffs, and probabilities. Together, these components transform intuitive guessing into disciplined forecasting about uncertain…
Vague probability language undermines decision quality despite providing a soft landing into probabilistic thinking. Terms like probably, likely, or unlikely mean vastly different things to different people, creating confusion in communication and unclear thinking internally. Precision matters…
Personal intuition, whilst valuable, suffers systematic biases that distort probability estimates. The inside view focuses on unique circumstances and specific details whilst ignoring broader patterns. The outside view grounds forecasts in base rates and reference classes, providing reality checks…
Not all decisions merit exhaustive analysis. Knowing when to invest heavily in decision-making versus when to decide quickly represents a crucial metaskill that compounds advantages over time by directing mental resources efficiently. Several frameworks help calibrate decision investment to actual…
Exclusively positive thinking creates dangerous blind spots despite dominating self-help advice. Systematically considering failure modes reveals obstacles, enables contingency planning, and improves execution. Simultaneously, maintaining information quality in group settings prevents groupthink and…
