This in my mind can be a dangerous path, if I am not disciplined to validate the new information. In all this the presumption is the "facts change", "information change", and "persuasion" is done from a basis of objective truth. In Keyes (btw Sun Tzu 孫子 said something similar a wee bit earlier) notes this presumption is present, such that the information added to financial decision is objectively true. But, in my experience in life (and even in investing) there are objective truths and then derivatives of objective & subjective truths. These second type of truths are often presented still as objective truths. To what percentage of the objective & subjective intermingle and when I decide the "truth" is now too subjective is... subjective. Its that puzzled look in my inner monologue that triggers the question "is this truth objective enough to be considered to influence my current stance?" In general I think as we gain more life experiences, the less subjective truths we tolerate in such derivative truths. Externally, this may manifest itself as jaded, or stubborn. And, finally, even when we think something is objective -> 2+2=5
