While it is true that all fields of historical science do not have the
luxury of "experimental" testing of hypotheses, testing does nonetheless
take place by way of deducing specific consequences that one can
investigate under the assumption that the causal events hypothesized were
the case. Experimentation sets up causal conditions in the present and the
researcher projects what effects will occur pending the ability of his/her
theory to account for those conditions. Historians can only project into
the future what might be found in the way of evidence that discounts one
causal event in lieu of some other causal event. The differences between
the historian and experimenter are matters of temporal scale and ability to

Some very nice accounts of this can be found in the following works by Karl

Objective Knowledge, pp. 347-361.
