The explanatory filter can be explained using a death investigation by a coroner as an example.  Suppose a 98 year old male has been found dead in his bed by the next door neighbor who noticed a noxious smell.  The coroner’s check list contains three possibilities: “natural cause” consisting of disease or physical necessity like a heart attack, “accidental cause” like the taking of too many pills from the wrong bottle, or “intentional cause,” like a homicide or suicide.  He can also report: there is no “best explanation,” – the data or “clues” are not sufficient to implicate any of the three possibilities.  If the coroner finds a knife in the back of the body he may do an autopsy to determine whether death resulted from that stab wound or from an earlier cause with the knife being placed after death to confuse the investigation.  If the knife wound caused the death, then it will likely be deemed a “smoking gun” that rules in design and rules out natural or accidental death.
