Editing Occam's razor (section)

==== Karl Popper ====
[[Karl Popper]] argues that a preference for simple theories need not appeal to practical or aesthetic considerations. Our preference for simplicity may be justified by its [[falsifiability]] criterion: we prefer simpler theories to more complex ones "because their empirical content is greater; and because they are better testable".<ref>{{cite book |last=Popper |first=Karl |author-link=Karl Popper |orig-year=1934 |year=1992 |title=Logik der Forschung |trans-title=The Logic of Scientific Discovery |edition=2nd |location=London |publisher=Routledge |pages=121–132 |isbn=978-84-309-0711-3 }}</ref> The idea here is that a simple theory applies to more cases than a more complex one, and is thus more easily falsifiable. This is again comparing a simple theory to a more complex theory where both explain the data equally well.
