I write about solving serial murder mysteries. I write about the police procedural processes used in solving muder mysteries. Let's think for a minute about these procedures and their use by detectives. It behooves detectives to use scientifical and mathematical and psychological methods to achieve their goal in pursuit of guilty perpetrators.
They must examine evidence; each piece is a building block. They must collect physical evidence and then witness statements, even gossip. They then systematize the evidence and put it into a format allowing for analysis. Where is the math? Well, as the detective connects dots and makes lists and adds, then synergy takes place. That's when the detective adds the human attribute of instinct, strickly personal, as inference is used often in interviewing, to make 2 and 2 equal 5. Voila - Synergy. Such fun.
