Answer:
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.
