# Discovery fiction

**Discovery fiction** is a style of pedagogy in which one presents a fictitious story about how someone could have invented an idea.

Michael Nielsen often talks about this idea, and he may have independently come up with it. But I think Tim Gowers also independently came up with the idea:

However, there is another way of justifying the introduction of a new concept into mathematics. Instead of looking at the

actualhistory of that concept, one can look at afictitioushistory. If you can tell a plausible story about why a conceptmight have beeninvented, then that is sufficient to make it seem reasonable. It solves the mystery of how anyone could have thought of the concept, and it also shows that it was pretty well inevitable that the concept would have been introduced sooner or later.^{[1]}
