This made me think that there are two type of not-earnestness: "what's in in it for me?" and "what's in it for others?" The first type is what [office] politics is about. The second type is rare and an example of it is when a doctor could tell a patient point-blank that he has 2 months left, but instead strongly recommends to go on a 2 months round-the-world trip and even invents a plausible cause [such trips help so much that savings on meds are multiples of the trip's cost].
