On the other hand, recognition of the subjective interpretation of probability has the salutary effect of emphasizing some of the subjective aspects of science. A particular scientist’s evaluation of the probability of some uncertain outcome must ultimately be that person’s own evaluation based on all the evidence available. This evaluation may well be based in part on the frequency interpretation of probability, since the scientist may take into account the relative frequency of occurrence of this outcome or similar outcomes in the part. It may also be based in part on the classical interpretation of probability, since the scientist may take account the total number of possible outcomes that
are considered equally likely to Nevertheless, the final assignment of numerical probabilities is the responsibility of the scientist herself.
