I don't really see that as the same thing as what the article was pointing out. Those are shibboleths that only an insider would know. You have to get the pronunciation of Cholmondeley or Couch "right" to pass for an insider.
The random misspellings, missing spaces, sloppy grammar, etc in the examples in the article seem different to me. Misspelling "en route" as "enriewu" doesn't show, "look, I know the secret country club spelling for en route". It simply shows that you don't have to care about your mistakes. You write something that approximates what you mean, and you're too important to spend time revising. The mistake could be "enrout" or "n route" or on any other word. But you're not going to be a try-hard who edits and frets over their messages, you're blessing someone with 10 seconds of your attention and they're lucky to receive your correspondence, typos and all.
Or its a simple signifier that the author was human, and that a real person is trying to convince you of something. I've experimented with putting minor grammar mistakes into my work of the sort that would be frowned upon, but are not strictly invalid. The existence of any kind of mistake makes the work sound "human".
Don't know about that as a general rule, since spam messages have had typos and mistakes in them since forever, and its precisely what marks them as not trustworthy.
More like signaling that a specific human wrote it themselves instead of one of their human assistants. The article is mostly about emails from the Epstein files so non-human authorship wasn't really a possibility at the time they were written.
I don't necessarily think it's that... it's just a matter of a rush to respond/send quickly and not take a lot of time. It's pretty easy to either fat-finger when typing on a keyboard, or gesture input on a phone to get the wrong word and you hit send before realizing.
Sometimes I'll notice right after, delete and re-reply (social media) other times I'll just let it be... It's pedantic busy bodies that will single you out for a typo as opposed to discussing the idea at hand.
The "enriewu" thing wasn't a misspelling of "en route", it was someone's name who had arrived in Miami with Jean-Luc and Peggy. It's probably a misspelling of Henry pronounced in French.
We’ve known since Socrates that writing instead of speaking eroded thinking. We seriously need to stop putting packaging, especially writing, on a pedestal. Instead we should put what little lifetime we have in sum towards focusing on what’s actually important: the ideas and concepts themselves.
