Sounds like you've been engaging sociopaths on their own turf, and yes I can see that in that environment everyone lies would be a true statement. Personnally, I don't lie about anything, and I find life to be very simple. I don't have to think about what I told to who, when. But I'm just an old developer who's been in the trenches for a lonng time.

You might read up on the gervais priciple, it explains a lot imo.
