What's the secret to writing well? As I've argued previously, an awful lot of people seem to think they know, yet their "rules for writers" are almost always (pardon the technical linguistics jargon) bullshit. For example, "Show, don't tell" is frequently bad advice. In the right context, the passive voice is fine. Elmore Leonard's most famous rule, "Never use a verb other than 'said' to carry dialogue", is sheer silliness. Even the sainted Orwell's rules are a bit rubbish: the final one is "Break any of these rules sooner than say anything outright barbarous", which means his advice is really just "Don't write barbarically". So it doesn't bode well that the psychologist Steven Pinker has published his own advice book, The Sense Of Style. Judging by a recent interview at edge.org, however, this one might be different. Writing, Pinker points out, is inherently a psychological phenomenon, "a way that one mind can cause ideas to happen in another mind". So one place to begin is with actual psychology.
