“The world’s greatest fool may say the Sun is shining, but that doesn’t make it dark out.”2 If you knew someone who was wrong 99.99% of the time on yes-or-no questions, you could obtain 99.99% accuracy just by reversing their answers. They would need to do all the work of obtaining good evidence entangled with reality, and processing that evidence coherently, just to anticorrelate that reliably. They would have to be superintelligent to be that stupid. A car with a broken engine cannot drive backward at 200 mph, even if the engine is really really broken.
