Books about luck and business judgment

A deal works out, and you want to know what to repeat. A different deal disappoints, and you want to know what to change. In either case, the next reading question can be more useful than a verdict on whether you are good at business: do you want to examine your approach to a decision, or understand how skill and chance shape results?

Start with Infinite Upside for a particular owner's judgment inside its circumstances. Consider Thinking in Bets for thinking about decisions under uncertainty, or The Success Equation for an analytical account of skill and luck.

1. Infinite Upside: a successful decision with a timetable worth questioning

   By Vijay Sheth.

   In Chapter 6 of Infinite Upside: Building Wealth With Room to Live, Sheth looks back at an acquisition he remains proud of. Recognizing value in the vehicles and changing the operation mattered. So did an unusual market and the speed at which sales and operating changes took effect.

   The chapter lets you admire the achievement and still question how little room it left for delay. Seeing value was not the same as having proceeds available when the company needed them. A timetable that worked once still deserves scrutiny before another purchase.

   Choose the memoir when you want to stay close to an owner's reasoning and the conditions around it. The account gives you something concrete to examine without making you accept every part of the original choice as equally strong. For the practical review itself, follow the separate decision-and-outcome exercise.

2. Thinking in Bets: examining how you judge a choice

   By Annie Duke.

   Thinking in Bets: Making Smarter Decisions When You Don't Have All the Facts concerns decisions made with incomplete information and outcomes affected by luck. Portfolio's description places uncertainty and the limits of what the decision-maker knows at its center.

   Consider an invented distributor whose customer renews after a competing supplier closes. The owner wants to improve how she evaluates her own choices. Her sample question for Duke could be: does this discussion help me describe my reasoning without letting the renewal do all the explaining?

   Investigate this option if you want to examine your thinking around a choice. Duke's author page links public samples, so you can try the treatment before choosing the book. Read for whether you can carry a clearer question back to a real discussion, rather than a phrase that merely makes a win sound deserved.

3. The Success Equation: understanding the skill-and-chance question

   By Michael J. Mauboussin.

   The Success Equation: Untangling Skill and Luck in Business, Sports, and Investing takes an analytical approach to their relative importance. Harvard Business Review Press presents the book as developing an explanation of skill and luck, analytical tools and implications for decisions.

   Return to the invented distributor with a different question: what evidence would justify attributing performance to skill? That makes an analytical explanation a candidate before she draws a lesson from this renewal or compares herself with another business.

   In an available passage, look for a distinction you can explain in your own words. Can you also identify what evidence your business would need before relying on it? That is a different reading emphasis from examining your habits of judgment, although the books share important territory.

Choose the reading purpose

You do not have to settle the role of luck before choosing a book. Decide what you want reading to clarify. You might want to follow one owner closely, examine how you evaluate a choice or understand how performance can be analyzed. A useful sample makes the next reading purpose clearer.

If the concern is a collection of unusually successful businesses, the reading on selected success stories examines what the collection leaves unknown. If a setback has raised the more immediate question of what to keep funding, the setback-reading selection addresses that choice.

For an owner's account that keeps achievement and a vulnerable timetable in view, read Infinite Upside. Try the opening for its voice, then use the decision notebook alongside your reading.
