 This judgment that, contrary to the IS model, the value that a candidate explanans assigns to an explanandum-outcome should not matter for the goodness of the explanation, is motivated as follows: When an outcome is the result of a genuinely indeterministic process we understand both high probability and low probability outcomes (the latter of which of course will sometimes occur) equally well: in both cases, once an SR model has been constructed, there are no additional factors that distinguish the two outcomes.
