Just more evidence that you can’t upgrade the brain’s firmware.  It’s disturbing that this cannot be overruled by conscious thought.  Then again, it’s just as mad when you realise what our eyes see and what we think we see.  That’s another can of worms.  I spent about ten minutes today trying to explain to my year 11 class that when we see yellow on the TV there is no yellow light coming from the screen.  It just tricks our brain into thinking it sees yellow.
