 In this case there is, Howson notes, a background theory that supplies a model of the experiment (it is a sequence of Bernoulli trials, viz., a sequence of trials with two outcomes in which the probability of getting either outcome is the same on each trial; it leaves only a single parameter to be evaluated). As long as we have good reason to believe that this model applies, our inference to the high probability of the hypothesis is a matter of standard statistical methodology, and the null support thesis is refuted.
