Confusion of The Inverse

Confusion of the inverse, also called the conditional probability fallacy or the inverse fallacy, is a logical fallacy whereupon a conditional probability is equivocated with its inverse: That is, given two events A and B, the probability of A happening given that B has happened is assumed to be about the same as the probability of B given A. More formally, P(A|B) is assumed to be approximately equal to P(B|A).

Famous quotes containing the words confusion and/or inverse:

    [Allegory] should ... be very sparingly practised, lest, whilst the writer plays with his own fancies and diverts himself by cutting the air with his wide spread wings, he should soar out of view of his readers, leaving them in confusion and perplexity to explore his viewless track.
    Sarah Fielding (1710–1768)

    The quality of moral behaviour varies in inverse ratio to the number of human beings involved.
    Aldous Huxley (1894–1963)
