equivalence paradox

the situation in which two different procedures produce very similar outcomes, despite having different initial assumptions or features. For example, two very different psychotherapy procedures may nonetheless produce very similar, positive outcomes, possibly due to the therapeutic relationship instead of the specific treatments. In statistics, the term refers to the fact that principal components analysis and factor analysis often produce a similar pattern of dimensions and loadings, although they each have a different premise.
