Objectivity in science is the property of scientific measurement that can be tested independent from the individual scientist (the subject) who proposes them. It is intimately related to the aim of verifiability and reproducibility. To be properly considered objective, the results of measurement must be communicated from person-to-person, and then demonstrated for third parties, as an advance in understanding of the objective world. Such demonstrable knowledge would ordinarily confer demonstrable powers of prediction or technological construction.
