Whenever science tries to explain a unique historical event or past phenomena, careful testing and repricability are by definition impossible. Instead, historical scientists try to construct a set of hypotheses about the causes and then look for a so-called "smoking gun", a piece of evidence which indicates that one of the hypotheses might be a better explanation than the others. Historical scientists commonly use:
- (i) the type of reasoning named abduction,
- (ii) inference to the best explanation and
- (iii) argument from analogy.
