Scientific Observations are based on ________.

Scientific observations rest on verifiable evidence or a systematic, citable body of proof open to independent checking.

Accumulated experiences are personal and unverified, so they cannot ground scientific observation.

Prejudices are biased preconceptions that distort rather than establish objective fact.

Beliefs of the people are subjective convictions lacking empirical testing.

Verifiability and replicability separate scientific knowledge from opinion.

Objectivity requires that any trained observer can confirm the same evidence.
