Bounded Rationality

mental-model

People make workable choices within limits of time, information, and search effort; rationality often means finding a sufficiently good option, not discovering the theoretical best one.

The best person for your career may be sitting in Cambodia. That does not mean you should search Cambodia—or the rest of the planet—before choosing whom to work with.

The optimum can cost more than it is worth

Every decision has two costs: the cost of the choice and the cost of finding a better one. Information is scattered, comparisons take time, and evaluating another alternative consumes effort. An exhaustive search can therefore make the eventual decision worse by delaying action or spending more than any improvement is worth.

Bounded rationality treats those constraints as part of the problem. You search within a reachable set, use imperfect signals, and stop when an option clears an acceptable threshold. The result may not be globally optimal, but it can be rational given the resources available. The important question becomes not “Is this the absolute best?” but “Is another round of search likely to repay its cost?”

Where it shows up

The unreachable perfect contact

Professional networking happens among people you can discover, approach, and evaluate. A theoretically superior contact elsewhere in the world is irrelevant if finding that person requires an unlimited search. Your real choice is among accessible relationships, not everyone who might possibly help your career.

A search limit is not an excuse for carelessness

Stopping early is sensible only when further search is genuinely costly relative to its likely benefit. For consequential or hard-to-reverse choices, the acceptable threshold should rise and the search should widen. Bounded rationality explains why perfect optimization is impossible; it does not make every convenient first choice rational.

Set the stopping rule before you search

For your next choice, specify the minimum acceptable criteria, how many alternatives you will examine, and what new information would justify extending the search. When an option clears the bar, choose it—unless the likely value of one more comparison exceeds its cost.
