Unknown Knowns Knowable With Tech and Training?

In a brief presentation at IR & Friends yesterday, Tom Gideon described research from his team which showed that measurements of physiological responses from subjects indicated they knew the correct answers to questions which they could not consciously articulate. Tom extended former United States Secretary of Defense, Donald Rumsfeld's famous  "There are known knowns" statement to cover an additional case: unknown knowns. This creates the interesting possibility that subjects could be trained, through a combination of technology and meditation into mindfulness, where they can consciously access knowledge and skills they did not know they had.
