Learning This Simple Mental Model Made Me Much Happier

It’s called Hanlon’s Razor and it’s well worth remembering!

Hanlon’s Razor is a favorite mental model of mine. It’s a lovely idea to apply liberally in both personal and professional life.

Beware — it’s deceptively simple. At first glance this might appear to be some soft, simplistic, pollyanna stuff — but actually it’s a deeply powerful tool for thinking! 💪

Who’s Hanlon? And what’s a “razor”?

In this sense, a razor is a not a shaving device, but a short philosophical statement which is a useful rule of thumb. It’s a shortcut that we can use to make our quick judgements be more accurate.

What is Hanlon’s Razor?

Never attribute to malice that which is adequately explained by stupidity.

When something bad happens to us, as egocentric humans we have a tendency to quickly judge that it was the result of malice — of some bad intent.

That person that cut you off in traffic? We can often automatically assume they are a selfish jerk. But if we apply Hanlon’s Razor, we might consider that maybe they are just quite an unskilled driver and possibly didn’t even see us.

That person who turned up late? Similarly we can often automatically assume that they don’t care about wasting our time, but if we apply Hanlon’s Razor we might consider that actually they might just be quite unskilled at managing their own time!

I know oftentimes I’ll be certain of the worst (leaving no room for benefit of the doubt) and then later I’ll get further information and find out that that my assumptions were completely wrong.

Hanlon’s Razor is warning us to be careful when assuming bad intent, because it’s much less likely that we tend to imagine.

I’ll leave the last word for Goethe, who wrote:

Misunderstandings and neglect create more confusion in this world than trickery and malice. At any rate, the last two are certainly much less frequent.

📖 Razors help us shortcut a whole load of cognitive bias. The king of this research is Daniel Kahneman, and his book Thinking Fast And Slow is one I recommend reading and then re-reading.
