Calibration

Shrink Definition

Calibration is the degree to which a person's confidence matches the actual accuracy of their knowledge, predictions, or decisions. A well-calibrated individual is appropriately confident when evidence is strong and appropriately uncertain when evidence is limited. Calibration reflects judgment quality rather than intelligence.

Plain language

Good thinkers make their confidence match the evidence.

Shrink Insight

Being certain isn't the same as being correct.

Why it matters

Calibration influences: • medicine • psychiatry • leadership • forecasting • investing • education • scientific reasoning Poor calibration can produce both overconfidence and excessive self-doubt.

Common misunderstanding

Calibration doesn't require low confidence. It requires accurate confidence.

Shrink Perspective

The best decision-makers continually recalibrate.

Shrink Reflection

When have you been more confident than the evidence justified?

Shrink Journal

Think of three recent decisions. How confident were you? Were those confidence levels justified afterward?

Shrink Step

Instead of asking, "Am I confident?" Ask, "Does my confidence match the evidence?"

Shrink Minute

Confidence should earn its place.

Shrink Takeaway

Accuracy matters more than certainty.

Evidence summary

Calibration has been extensively studied in decision science, psychology, medicine, and forecasting. Better calibration has been associated with improved judgment, forecasting accuracy, and professional decisionmaking. Medical Boundary Calibration improves reasoning but can't eliminate uncertainty or guarantee correct decisions.
