Even a smart person can have a bad day / moment of weakness. If you are super busy / stressed out and some email comes that looks like a bullshit request from HR or IT or whatever, it can be tempting to just try to knock it off your plate real quick so you can get back to whatever fire you were fighting.
My tactic these days is I pretty much don’t click on ANYTHING in an email, so it’s an ingrained habit. If it’s a link to something, it’s usually one I can navigate to myself using my browser. If it’s an attachment, we use a file sharing system that stores these so I can just go to that and see what’s in there.
It’s inconvenient, and you don’t always have these work-around options, but by trying to make into an automatic habit, it has saved me a couple of times.
