What was the outcome of the experiment with the blind doctor, T. N., that is described in "Blind, Yet Seeing"?

The blind doctor was able to navigate safely through the obstacles along the hallway, 'guiding' him to safely walk without hitting the obstacles.

Explanation:

Benedict Carey's article "Blind, Yet Seeing" from The New York Times reports the physical case of blindsight, which can be overcome by a person. The article also discusses how the subconscious mind of a person is capable of helping a person 'overcome' certain obstacles despite being physically blind.

In an experiment conducted, a well-educated blind doctor was asked to participate which he initially refused. His stance was that he "had no interest in navigating an obstacle course - a cluttered hallway - for the benefit of science." True. But when he did agree to be a part of it, his subconscious mind helped him "zigzag down the hall, sidestepping a garbage can, a tripod, a stack of paper and several boxes as if he could see everything clearly." This shows that the subconscious mind is still able to 'aid' a person despite physical blindness.
