An interesting theory: that changing the spacing between words in long blocks of text can help improve reading comprehension. It’s interesting because it goes against all modern notions of typographical design. If you want a designer to hiss at you like a cat over water, just show them a paragraph of non-hyphenated justified text, and the subsequent “rivers” of whitespace it produces.
Design purity aside, I did feel like I was reading the Asym-spaced text faster than the “regular” text, but it’s hard to know whether this was true or a placebo brought on by the article headline. Either way, if you feel it helps you, there’s a browser plugin you can download to apply the chunking more universally (although, as always, be aware you’re allowing a third-party company access to your browsing habits when you do, so… yeah).
