Update: A more recent version of this material appears in my book,Â The Curious Journalist’s Guide To Data.
I’m not convinced that journalists are always aware when they should be thinking about numbers. Usually, by training and habit,Â they are thinking about words. But there are deep relationships between words and numbers in our everyday language,Â if you stop to think about them.
A quantity is an amount, something that can be compared, measured or counted — in short, a number. It’s an ancient idea, so ancient that it is deeply embedded in every human language.Â Words like â€œlessâ€ and â€œeveryâ€ are obviously quantitative, but so are more complex concepts like â€œtrendâ€ and â€œsignificant.â€ QuantitativeÂ thinking starts with recognizing when someone is talking about quantities.
Consider this sentence from the article Anti-Intellectualism is Killing America which appeared in Psychology Today:
In a country where a sitting congressman told a crowd that evolution and the Big Bang are â€œlies straight from the pit of hell,â€ where the chairman of a Senate environmental panel brought a snowball into the chamber as evidence that climate change is a hoax, where almost one in three citizens canâ€™t name the vice president, it is beyond dispute that critical thinking has been abandoned as a cultural value.
This is pure cultural critique, and it can be interpreted many different ways. To start with, I donâ€™t know of standard and precise meanings for â€œcritical thinkingâ€ and â€œcultural value.â€ We could also read this paragraph as a rant, an exaggeration for effect, or an account of the authorâ€™s personal experience. Maybe itâ€™s art. But journalism is traditionally understood as â€œnon-fiction,â€ and there is an empirical and quantitative claim at the heart of this language.
