From what I understand of modern philosophy of mind, what the brain accepts as true happens at a subconscious level, while providing the illusion of having made conscious choices.
"The unsettling point about modern philosophy of mind and the cognitive neuroscience of will, already apparent even at this early stage, is that a final theory may contradict the way we have been subjectively experiencing ourselves for millennia. There will likely be a conflict between the scientific view of the acting self and the phenomenal narrative, the subjective story our brains tell us about what happens when we decide to act. (p. 127)
From a scientific, third-person perspective, our inner experience of strong autonomy may look increasingly like what it has been all along: an appearance only. (p. 129)"

Sure, but I do recall how evasive you got when asked to demonstrate, even to yourself, that they are a
conscious choice.
