Does IT attract the most liars/fakes?

I don’t think so, but it’s vastly harder in most IT roles to fake it till you make it as compared to many other careers. If you claim to be able to set up a network and there’s no functional network after, it’s pretty dang obvious you have no idea what you’re doing.

In IT it’s often just a matter of hours until it becomes clear that you’re an incompetent or a liar (or both). On the other hand, in other fields I’ve seen people coast sometimes years with little to no relevant knowledge or skills. This is just not possible in my field in most places because you must almost-immediately create or troubleshoot things that actually function in the real world.

It’s usually clear to me within five minutes of working with someone in IT if they know their stuff or not. I don’t think that’s true in a lot of other roles, particularly ones that rely on more soft skills and gladhanding.

This seems somewhat common:

I was in Germany years ago talking with an acquaintance about traveling. She mentioned that she and her family were going to spend three days in the US and planned to see Hollywood, the Grand Canyon, NYC and Florida in that time.

I explained as gently as I could that those places were thousands of miles apart and while it might be just barely remotely possible to visit all those locales in three calendar days, they’d be doing nothing but travel the entire time and see absolutely nothing in any of their chosen destinations. She said she didn’t realize the US was so enormous and they’d look into making other plans. (Maybe I averted a ruined vacation?)
