<blockquote>Say there is an accepted theory which says that better nutrition can improve a patient’s condition. We know from the discussion in the previous section that the conjunction of this proposition with the basic requirement to accept only the best available theories yields a requirement that the factor of improved nutrition must be taken into account when testing a drug’s efficacy.

Now, envision a method which doesn’t take the factor of better nutrition into account and prescribes that a drug’s efficacy should be tested in a straightforward fashion by giving it only to one group of patients. This method will be incompatible with the requirement that the possible impact of improved nutrition must be taken into account. Therefore, indirectly, it will also be incompatible with a theory from which the requirement follows.[[CiteRef::Barseghyan (2015)|p.163-4]]</blockquote>
