To judge a conjecture believable, in the context of a story, is to assess the degree to which it makes the story one starts with into a prototypi cal story; "a prototypical story identifies a protagonist, a predicament, attempts to resolve the predicament, the outcomes of such attempts, and the reactions of the protagonists to the situation" (Robinson & Hawpe, 1986, p. 112). If a conjecture strengthens one of these five elements in the story that spurs theory construction, or if it supplies an element that is missing, then the conjecture is more likely to be retained. If, however, the conjecture neither strengthens nor completes, then it is likely to be rejected.
