I love the ending of the original study: “we should probably be arguing passionately about things that are more important.”
But I don’t love the first author’s quote in the Atlantic article: “Our data suggest that all readers benefit from having two spaces after periods.” Why, then, does their peer-reviewed article end with: “Punctuation spacing… did not affect comprehension, and only increased overall reading speed for participants who already type according to this two-space convention…”?
The above quote about two-spacing benefiting all readers, from what I can tell, is related only to eye tracking. It feels disingenuous to claim everyone benefits from two-spacing when arguably more important factors, such as comprehension and reading speed, are unaffected by spacing or slightly affected for only a subset of participants.
It’s worth noting, too, that this article and study are from 2018 and the most recent version of the APA manual (7) recommends only one space after punctuation. I was worried all my recent writing was breaking form.
