I’ve started reading Thinking Fast and Slow by Daniel Kahneman(check out my Kindle highlights)

Kahneman was one of the first to identify cognitive bias in our thinking, and this book describes a metaphor for two systems of thinking; System 1 (fast, intuitive, prone to bias) and System 2 (slow, methodical, conscious) working together to influence our interaction with the world.

System 1 is generally to do with emotion and feeling, but it also deals with facts if those facts have a strong belief behind them (for example, 2+2=4; Paris is the capital of France).
I have often coached people to use strong metaphors to express their ideas, and reading the early chapters of this book, I think part of the reason that I do this is that strong metaphors are much easier to absorb into System 1.

An engaging story is easier to absorb and express to others than a complicated description that requires conscious attention. This applies as much to code as is does to writing or speaking.
