Inductive reasoning, however, allows Sherlock to extrapolate from the information observed in order to arrive at conclusions about events that have not been observed. Here, we see the intrepid detective walking into the scene a blank slate; he has no pre-supposed ideas about what may have taken place. Maybe the woman on the ground died of natural causes, maybe she was murdered, maybe she fell through the ceiling from an airplane flying thousands of miles above. He simply doesn’t know. So he looks. There’s the ash from her cigarette, so she couldn’t have fallen from a great height. There’s the glass from a broken window, but this might have already been broken when she arrived, or it may have been broken in a struggle. Does she have lacerations? Is her dress damp from the rain outside or dry? And he goes on to gather information until he arrives at a conclusion — that still may be incorrect. And yet more information will come and come until he is quite sure he’s arrived at the right conclusion.
