Woah what? Seriously?
Back when I was starting my career, I had an acquaintance tell me that "everyone lies" and to feel free to pad my resume, because "everyone does it" and if I didn't do it, then my overall impression will be discounted anyways down to below what my actual capabilities were.
I always chalked that up to him being a sales guy, so of course he's going to lie cheat and steal his way to the top, and insist that everyone should do the same.
When I have interviewed candidates, I can tell when someone has lied about something, because they can't talk through their process for doing the thing they claimed to have done. The details won't be there, and/or will be wrong. It's not common.
I don't put stuff on my resume that I can't speak to. Things I don't remember that well, I remove - no point in putting down stale skills that you're going to get dinged on.
On the other hand - Psychology Today as a source of such things has been known to post articles like this on topics which have been roundly debunked in the field. So this could also be one of those bad opeds.
