In essence, the study basically proved very little, except that it really doesn’t matter if you use one space or 2 after a period. At least, that’s what my confirmation bias tells me the story says, since I plan to continue using 2 spaces after a period any time I’m writing on a real computer keyboard. Also, I completely overlook my own confirmation bias when I’m typing on my iPad or iPhone keyboard and use a single space, because it’s convenient, and I’m human, so who says I have to be consistent, anyway?
