> I'm not sure why your co-workers' IQ is your concern It's a concern as much as working with a smart person that can understand - and support, and improve on, and challenge if needed - your ideas is a delight and brightens your day. And working with somebody who can't get the basic things and you have to waste time on explaining the obvious and treading water instead of moving forward is a drag and makes your life hell. Of course we're not talking about IQ score on a puzzle test or something like that - I'm sure the OP talks about practical skills as seen in everyday interactions. I've been lucky to work mostly with very smart people - but occasionally there was a dud, and it's very annoying and sucks a lot of energy out.
