The Unknown Unknowns Lab

Record what is supported and the specific question that remains unanswered.

Explain why an omitted variable may be noticed only after an unexpected result.

Separate feeling surprised from observing a result inconsistent with a prediction.

Compare missing information, an unusual observation and incompatible claims.

Record the question, current explanation, missing observation and next inquiry.

Separate what a record shows from the cause proposed to explain it.

Write a prediction and its assumptions before checking an outcome.

Preserve time, conditions and changes made during an observation.

Compare repeating one measurement with checking through another method or observer.

Record the mismatch, its size, uncertainty and conditions without supplying an immediate explanation.

List what the model includes, excludes and treats as fixed.

Identify interactions that a list of independent factors would overlook.

Trace the source and supporting evidence for each important assumption.

Compare predicted and observed values and examine structured differences.

Create a second explanation that predicts a different observable result.

Ask why two ordinary room thermometers give different readings in a teaching example.

Record location, timing, nearby heat sources and the displayed readings.

Compare calibration difference, response delay and local temperature variation.

Swap positions, allow stable readings and compare repeated differences.

Identify what was resolved and the remaining comparison needed to distinguish causes.

Compare repeated variation with uncertainty about the quantity being measured.

Identify the smallest difference or signal a method can reliably distinguish.

Check instrument effects, processing errors and altered samples before interpreting an anomaly.

Compare detection errors under explicit thresholds and base rates.

State which effect size and conditions a non-detection can constrain.
