Thus, even if you are very creative in generating hypotheses, you might generate really awful ones and shouldn’t believe any one of those. This has prompted some to eschew the use of IBE altogether, especially insofar as it pertains to unobservables (things we can’t directly see or otherwise sense, such as electrons or magnetic forces). In short, IBE can provide some reason for accepting a claim (we use it in forensic sciences all the time, for example, when we try to find the person whose presence is the best explanation of all the clues, and infer that the person who best fits the clues is the perpetrator), but it certainly doesn’t guarantee our knowing the truth.
Finally, it is important to point out that IBE cannot be reduced to other forms of inductive inference. Inferring the presence of a stray cat in my attic as the best explanation of the noise I am hearing does not (need to) involve prior observations of stray cats in my attic and their behavior. Thus, this inference is different from a statistical inference, which, if you recall the example of koalas, does rely on observations of the feeding habits of a number of koalas to infer something about what other koalas will eat. Neither am I trying to establish any sort of regularity when I infer that a cat must have gotten into my attic. I am simply interested in explaining this particular and odd event by evaluating various hypotheses as to their plausibility in light of my background knowledge about cats, none of which I need to have oberved in an attic.
