Science requires objective and verifiable observation through empirical research, demanding both objectivity and critical testing of theories against reality.
Objective and verifiable observation, established using evidence collected through empirical research, is a key aspect of science. The requirement of empirical evidence ensures that scientific knowledge is grounded in objective, tangible evidence that can be observed repeatedly.
In addition to being empirical, science demands objectivity to reduce personal bias. The scientific method mandates systematic observation, skepticism, and logical reasoning to draw objective conclusions.
Scientists must constantly test their theories against reality, as scientific theories can only survive until the next confrontation with empirical evidence, according to Karl Popper's viewpoint.
