Here's the basic order of belief cognitively: It has names but I
   don't remember them; you can see it on the
   electroencyphalegraphiweroijewrpoawer things. [I'm NOT going to
   try spelling - my coffee isn't finished yet].

   When faced with novel/unexpected stimulus, It goes like this:

   NO-YES................. NO/YES/MAYBE/SOMETHING-ELSE

   Inhibition/NO (rejection - like how the first bite of an
   unexpected food makes you want to spit it up for *just a tiny
   moment* - same mechanism but in the brain instead of mouth)
   quickly followed by acceptance/YES... then about 400ms later
   (might be 200ms - either way it's a long time at this scales -
   there's musical notes shorter than these number)... then YOU can
   consciously control it all better.

   But the initial order is NO -> YES... and the YES has enough
   sticking power to make it into the consciousness.

   [again, this is for novel stimuli, not expected/assumed stimuli)
   You _can_ witness initial no/yes --> rational decision-making
   process but it takes a little awareness / introspection. Can't
   really CONTROL it at that fast level, but you can watch it
   happen and then notice the moment you have control.
