hypothetico-deductive method, also called H-D method or H-D, procedure for the construction of a scientific theory that will account for results obtained through direct observation and experimentation and that will, through inference, predict further effects that can then be verified or disproved by empirical evidence … What is Hypothetico-deductive method with example?
The raven paradox is a famous example. The hypothesis that ‘all ravens are black’ would appear to be corroborated by observations of only black ravens.
