Yes, I would admit we often tell ourselves things that simply are not true. This can be a study in itself. Is it out of fear, ignorance or wishful thinking? Or are we determined to DO something and are waiting for an "excuse" or a "good, or good sounding reason" to do so? As a Scientist (Retired) myself, I am aware that ALL of these things must be considered before I actually DO come to a conclusion, and even then, I always am on the watch to see if I was wrong. If such things are even "tricky" for me, I would guess that it would be worse for more "normal", "emotional" people to get to the truth as to what motivates them--- I suppose that's where therapy comes in. In a way, I envy those who are NOT curious for answers, and not HAVE to know.
