And, of course, you're incapable of looking one up.
The
scientific method is an
empirical method for acquiring
knowledge that has characterized the development of
science since at least the 17th century (with notable practitioners in previous centuries; see the article
history of scientific method for additional detail.) It involves careful
observation, applying rigorous
skepticism about what is observed, given that
cognitive assumptions can distort how one interprets the
observation. It involves formulating
hypotheses, via
induction, based on such observations; the
testability of hypotheses,
experimental and the measurement-based statistical testing of
deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are
principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises.
Although procedures vary from one
field of inquiry to another, the underlying
process is frequently the same from one field to another. The process in the scientific method involves making
conjectures (hypothetical explanations), deriving predictions from the hypotheses as logical consequences, and then carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture, based on knowledge obtained while seeking answers to the question. The hypothesis might be very specific, or it might be broad. Scientists then test hypotheses by conducting experiments or studies. A scientific hypothesis must be
falsifiable, implying that it is possible to identify a possible outcome of an experiment or observation that conflicts with predictions deduced from the hypothesis; otherwise, the hypothesis cannot be meaningfully tested.
The purpose of an experiment is to determine whether
observations agree with or conflict with the
expectations deduced from a hypothesis. Experiments can take place anywhere from a garage to a remote mountaintop to CERN's
Large Hadron Collider. There are difficulties in a formulaic statement of method, however. Though the scientific method is often presented as a fixed sequence of steps, it represents rather a set of general principles. Not all steps take place in every
scientific inquiry (nor to the same degree), and they are not always in the same order.
