Sherlock Lecture Slides From Friday

We were talking about 2 theories of human intelligence, which we simplistically polarized as Theory 1, Only Sherlock is Sherlock, and Theory 2, Anyone Can Be Sherlock, But Almost Nobody Does the Work.  Here's a slide I raced through about how his personality helps.  Theory 1 or Theory 2? I know you know.

Also there was the kind of closure the "whodunit" or "mystery" offers, particularly before all hell breaks loose for the UK and Europe in World War I.  It gets much harder to make convincing in crime fiction later on.
