EvidentlyThe ''double-blind trial method'' is a further example of the relation of ''implementation''.|Example Type=Historical}}{{Theory Example|Title=The Double-Blind Trial Method (Two Scenarios for Method Employment)|Description=As Barseghyan explains, the "it is obvious that [''the double-blind trial method'' ] is also an apparent based on our belief that by performing a double-blind trial we forestall the chance of unaccounted effects, placebo effect, and experimenter’s bias".[[CiteRef::Barseghyan (2015)|pp. 141]] The propositions that this premise is based on in turn derive from theories that are acecpted; for example , "our belief that a trial with two similar groups minimizes the chance of unaccounted effects follows from our knowledge about statistical regularities, i.e. from our belief that two statistically similar groups can be expected to behave similarly ''ceteris paribus''". [[CiteRef::Barseghyan (2015)|pp. 142]] Similarly, our knowledge of physiology and psychology lead to our understanding that we can void the relation placebo effect with fake pills.[[CiteRef::Barseghyan (2015)|pp. 142]] Our knowledge of psychology allows us to understand that researchers can bias patients from their own knowledge of which group is which.[[CiteRef::Barseghyan (2015)|pp. 142]] Clearly, these premises, although trivial, are currently accepted within our scientific mosaic.[[CiteRef::Barseghyan (2015)|pp. 142]] Hence, the ''double-blind trial method'', although an ''implementation'' of abstract requirements, is still based on our currently accepted theories.This is true in all scenarios of ''implementation''.[[CiteRef::Barseghyan (2015)|pp. 142]] Thus, methods follow deductively from elements of the mosaic whether they follow strictly from theories and methods or implement abstract requirements. This is an important similarity between the two scenarios for method employment.

A final change in method occurred when ''experimenter's bias'' was discovered:
<blockquote>The researchers that are in contact with patients can give patients conscious or unconscious hints as to which group is which. It is possible that the positive effect of the drug established in a blind trial was due to the fact that the patients in the placebo group knew that they were given a placebo. The method of drug testing was modified yet again to reflect this newly discovered phenomenon. The contemporary approach is to perform a double-blind trial where neither patients nor researchers know which group is which.[[CiteRef::Barseghyan (2015)|pp. 135-6]]</blockquote>
