Seeing And Observing Sherlock

Pardon me while I unitask.

I’m reading a delightful book by Maria Konnikova, titled Mastermind: How To Think Like Sherlock Holmes. It covers much of the same territory as other books I’ve read on thinking, deducing, and questioning but it reads more like … well, like a detective novel. In other words, it’s fun.

In the past, I’ve covered Daniel Kahneman’s book, Thinking Fast and Slow. Kahneman argues that we have two thinking systems. System 1 is fast and automatic and always on. We make millions of decisions each day but don’t think about the vast majority of them; System 1 handles them. System 1 is right most of the time but not always. It uses rules of thumb and makes common errors (which I’ve cataloged here, here, here, and here).

System 1 can also invoke System 2 – the system we think of when we think of thinking. System 2 is where we logically process data, make deductions, and reach conclusions. It’s very energy intensive. Thinking is tiring, which is why we often try to avoid it. Better to let System 1 handle it without much conscious thought.

Kahneman illustrates the differences between System 1 and System 2. Konnikova covers some of the same territory but with slightly different terminology. Konnikova renames System 1 as System Watson and System 2 as System Holmes. Konnikova proceeds to analyze System Holmes and reveal what makes it so effective.

Though I’m only a quarter of the way through the book, I’ve already gleaned a few interesting tidbits, such as these:

Motivation counts – motivated thinkers are more likely to invoke System Holmes. Less motivated thinkers are willing to let System Watson carry the day. Konnikova points out that thinking is hard work. (Kahneman makes the same point repeatedly). Motivation helps you tackle the work.

Unitasking trumps multitasking – Thinking is hard work. Thinking about multiple things simultaneously is extremely hard work. Indeed, it’s virtually impossible. Konnikova notes that Holmes is very good at one essential skill: sitting still. (Pascal once remarked that, “All of man’s problems stem from his inability to sit still in a room.” Holmes seems to have solved that problem).

Your brain attic needs a spring cleaning – we all have lots of stuff in our brain attics and – like the attics in our houses – a lot of it is not worth keeping. Holmes keeps only what he needs to do the job that motivates him.

Observing is different than seeing – Watson sees. Holmes observes. Exactly how he observes is a complex process that I’ll report on in future posts.

Don’t worry. I’m on the case.
