So, why simplicity over other inductive methods?  There are certain times when choosing the simplest hypothesis is preferable.  One example is when there are two competing, equally “relevant and testable” hypotheses that seem to have “predictive power that is roughly equal” (Copi 522).  In this situation, we can opt to choose the “simpler” of the two competing hypotheses.
