look at the mirror
It does not matter if you are a lawyer, a politician, or a scientist. Back of your head, cunningly hidden inside, you may know what you are doing is BS. But human psychology goes such that you do not care, as far as you are rewarded, got good pay, power, success, papers in good journals, and in a good position in academia. It should not be. In principle, these jobs have fundamental goals, saving people's rights, making people's lives better, and making true contributions to human knowledge. There should be a moment that you go, "Wait a minute. What am I really doing???", by looking at you from distance, or at the mirror.
But do you do it?
And how many people out there can do it?
