Neuroscience Readies for a Showdown Over Consciousness Ideas

Philip Ball in Quanta:

The question of what kinds of physical systems are conscious “is one of the deepest, most fascinating problems in all of science,” wrote the computer scientist Scott Aaronson of the University of Texas at Austin. “I don’t know of any philosophical reason why [it] should be inherently unsolvable” — but “humans seem nowhere close to solving it.”

Now a new project currently under review hopes to close in on some answers. It proposes to draw up a suite of experiments that will expose theories of consciousness to a merciless spotlight, in the hope of ruling out at least some of them.

If all is approved and goes according to plan, the experiments could start this autumn. The initial aim is for the advocates of two leading theories to agree on a protocol that would put predictions of their ideas to the test. Similar scrutiny of other theories will then follow.
