The philosopher Ned Block, of NYU’s Center for Neural Science, describes something he’s observed in his students akin to different personality types when he lectures about the hard problem of consciousness. He estimates that about one-third of his students “don’t appreciate phenomenology [felt experience] and the difficult problems it raises,” and he thinks it would be interesting to study the neurological difference between people who are able to intuitively grasp the hard problem and those who aren’t (or who view it as an illusion).
