Bounded Rationality
Reasoning always has limits.
Evidence: established. We label every concept honestly, and say so when it's a teaching model. How we rate evidence.
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.
Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
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.
