Growing up, I read a substantial chunk of Roald Dahl’s output. I liked them not just for the stories, but how he would explain concepts to his young readers. It was through his novels that I learnt why payments of royalties are made, how some fighter jets fired missiles through the propellor, and that finds of certain metals need to be reported to the authorities.
But learning from fiction is in no way restricted to children’s books. Anyone can glean or dispute historical stories from Dan Brown, or learn a little about the law from John Grisham.
A personal favourite is The Day of the Triffids, where a character talks about risk management by using an example from his family farm. It was explained that once in a while, the cows would bunch together and burst through the perimeter fence, yet it was so rare and unpredictable that it was quicker and cheaper to fix breaks as they occurred than to reinforce the whole fence.
And then I read Lee Child giving praise to Frederick Forstyth as The Day of the Jackal turns half-a-century old. The entire novel is almost a textbook for an assassination, such is the level of detail. The hitman isn’t a spiv with limitless resources. We see how he funds his operation and where his weapon and fake documents are obtained.
Yet the reader is never overloaded with lists of data. The key technique is to convey much of the detail via dialogue. At the very beginning, for example, a suspect begins to tell the police about the assassination plot, and the reader learns the details at the same time as the officers.
I feel compelled to leave a caveat here that anything learnt in fiction should always be cross-checked with a non-fiction source. That’s doubly true if you plan to include something educational in your own work.
