Retrodiction (or postdiction, though this should not be confused with the use of the term in criticisms of parapsychological research) is the act of making a "prediction" about the past. ==Scientific method== In scientific method, the terms ''retrodiction'' or ''postdiction'' are used in several senses. One use refers to the act of evaluating a scientific theory by predicting known rather than new events. For example, a theory in physics that claims to extend or replace the standard model but that fails to predict the existence of known particles has not met the test of ''postdiction''. Michael Clive Price has written:
Another use refers to a process by which one attempts to test a theory whose predictions are too long-term to be tested by waiting for a future event to occur. Instead, one speculates about uncertain events in the more distant past, and applies the theory to consider how it would have predicted a known event in the less distant past. This is useful in, for example, the fields of archaeology, climatology, evolutionary biology, financial analysis, forensic science, and cosmology. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「retrodiction」の詳細全文を読む スポンサード リンク
