Well, not necessarily lazy. But descriptions of LSIs and ESIs lead me to believe that they are all hard-working, diligent people who pay great attention to detail.
Is this indeed the case?
I know a friend I wonder if might be ESI, but she has said things like she is very good at finding the quickest way to do things while still doing a good job (and she does indeed do a good job on most things). Perhaps this is efficiency... she might be dualized, I suppose.
