Great article, abduction and abductive inference seems to be ignored or forget by all but artificial intelligence engineers.
To answer your final question, “[who messed up and forgot to mention abduction?]” Id argue Doyle was unaware of abduction, as Pierce barely began writing about it until 1865. Though Doyle wrote his first piece on Sherlock in 1887 (plenty of years later), I suspect abduction had not been popularized to any significant degree.
Or, perhaps it was simply because Doyle knew his audience well enough, and understood deduction to be hard enough concept to push without muddying it with other forms of induction.
