Between the first draft of my novel and the second I went cold turkey and switched from two spaces after a sentence (which I’ve been doing for half a century or so) to one space. I did a global search-and-replace through my manuscript and changed all eleventy-billion occurrences of “period-space-space” to “period-space”. I typed all my new sentences with one space between them. I switched over to single spaces in my emails as well. And I will never look back.
Yes, I know, this was an amazing achievement. Appreciate the congrats. I did it mainly because those extra spaces were going away when the document was prepared for publication. Also, at work I work on a lot of documents with multiple authors, and it is moderately important to be consistent. Also, I just wanted to show myself what I was capable of.
Anyway, here’s a study that purports to show a slight benefit to two spaces after a period. This gets the authors a feature article in the Washington Post, but the study has lots of issues, as this wonderful article in Lifehacker points out. The key issue is that the study uses a monospace font. But nobody nowadays uses a monospace font, except for showing computer code or the like!
[R]eading a proportional font and a monospace font are two completely different scenarios. The study even acknowledges this: “It is possible that the effects of punctuation spacing seen in the current experiment may differ when presented in other font conditions.” Of course it’s possible—that’s what the whole debate is about! Why would you use Courier New!
So the study is pretty bogus, but I suppose the money from the two-space lobby will continue to roll in, and the researchers will go on speaking tours, write best-selling books, appear on major talk shows, etc. Good for them. But I will have the quiet satisfaction of having done the right thing by switching to one space, even at enormous personal cost. Not all heroes wear capes.
