I intend to speak truth. I therefore need to differentiate between what I can have confidence in because I have tested it and not been able to disprove it, and my assumptions, biases, and and things I am wrong about. That last is difficult, because if I know I'm wrong I change my mind, so this then impels me to moderate my statements and claims, to be sure what I say remains factually correct even if I'm wrong, because I surely am wrong. I try to state things so that I am not asserting knowledge or certainty I cannot have.
I vastly prefer to be vague and uncertain than to lie or mislead. This clearly makes me unsuitable as a cult leader or politician, and I have to accept my limitations in that wise.
