It's funny that the expert in the article says exactly the opposite of the article:

    > "I think most people are mistaken about it," said Hurlburt. "People are hyper-confident. 'Yes I have inner monologue.' And other people say, 'No I don't have a monologue.' And the chances are pretty good that both sides of the debate are mistaken."

    > Hurlburt said what he calls "armchair introspection" likely won't teach you much about your own mind because the act of paying attention "screws up your everyday inner life."

I think he is saying we all have all aspects of thinking, to varying extents and therefore everyone has inner monologue to some extent.
