Bounded Rationality

Shrink Definition

Bounded rationality recognizes that human decisions are constrained by limited time, limited information, limited attention, limited memory, and limited computational capacity. Rather than making perfectly rational decisions, people generally make decisions that are sufficiently good given the constraints they face.

Plain language

People don't make perfect decisions. They make the best decisions they can with what they have.

Shrink Insight

Many poor decisions aren't failures of intelligence. They're consequences of limited resources.

Why it matters

Bounded rationality explains: • decision shortcuts • heuristics • satisficing • organizational behavior • healthcare • leadership • economics

Common misunderstanding

Limited rationality doesn't imply irrationality. It reflects realistic human constraints.

Shrink Perspective

Perfect decisions rarely exist. Thoughtful decisions usually do.

Shrink Reflection

Which important decisions have you judged unfairly because you expected perfection?

Shrink Journal

Describe one difficult decision. What constraints existed at the time?

Shrink Step

Evaluate past decisions using the information available then, not what became known later.

Shrink Minute

Good enough often outperforms impossible.

Shrink Takeaway

Human thinking operates within limits.

Evidence summary

Bounded rationality, introduced by Herbert Simon, transformed economics, psychology, organizational science, and artificial intelligence by recognizing that real-world decision makers operate under cognitive constraints.
