> Now, a study that recorded patterns of brain activity in 15 participants suggests that colours are represented and processed in the same way in the brains of different people.

They're not asking the same question though. Neuroscientists are asking whether the brain processes the physical substrate (photons) that precedes the experience in the same way. Philosophers are asking if the subjective experience that follows (the qualia) is identical. The former is the easy question. The latter is the impossible question.

Interesting, but I'm not convinced that it actually settles (would settle, if the "suggestion" is confirmed) the philosophical question.

Then I notice a loose screw and tighten it. Now you see Bob's blue as orange.

Was the machine properly functioning with the screw loose or tightened? Was it properly functioning in either configuration? How would you prove it?

Either way, both fields really seem to fumble around when they approach the other's domain.
