Preflight checks of the control surfaces before hitting the throttle should be as routine as wiping before flushing.
However, I did lose a plane last spring to reversed ailerons. I must have had a dislexic moment because I did check them, then I thought they didn't look right so I asked my spotter what he thought, told me they looked fine to him. He's dislexic too.
when in doubt, get a third opion.
