Socially, conversationally, I’ve done this a lot. I’m not trying to pose as anything I’m not or assert an undeserved claim. Rather, I’m looking for interesting conversation. Watered-down beginner-level stuff is generally boring. I have enough knowledge about enough things to want to skip over as much of that as I can and get to the good stuff.
If I know a little bit about a subject, just enough to ask an intelligent question, I can get a knowledgeable person talking about the subject in a way that they simply won’t do if they think I know nothing about their field. Then I really do learn something.
I never claim the knowledge—just let someone else assume it. And if I really have to ask what something means, I do, without fear of sounding stupid. People are usually more than happy to explain.
This same ploy works doubly well when it comes to (a) the workplace, (b) confidential topics, and (c) confidential topics in the workplace. Again, I never lie about what I know. But if someone says, for example, “I assume you heard what happened to Karen,” I don’t say “No—what??” I say, making my shrewdest guess, “I know she’s been out a lot lately,” or “You’re talking about the thing yesterday with the presentation, right?” or “I know she’s still having her problems with Vic.” This type of response always elicits information that I would never get if I just waited to have everything filled in. People who think they ought to be discreet are only too happy to open up once they think you already know something; then they aren’t the one spilling the beans. (Even if they really are.)
By the same token (the other side of the same token, actually), playing dumb when you do know something can net you an earful. When someone has told me something confidentially, I never break the confidence. Never, never, never. And when people trust you, they will tell you things.
This means I may still be keeping mum about something that used to be secret even after everyone else has started talking about it. BUT sometimes people will tell you more than they mean to when they think you don’t know its significance. So you can use your privileged knowledge to ask a seemingly innocent question and get back a tidbit of information that they would never give you if they thought you had the rest of the picture. And in this way you can get hold of the whole story without anyone’s realizing you have it.
Being able to do this in the workplace can, believe me, be a really valuable skill. There are fewer surprises, and you can take steps to protect yourself and those who deserve your loyalty when things get dicey. In between crises, it just adds to the entertainment value of being at work.
