The "No offence" prefix communicates a connotation that is strongly at odds with your elucidation above.

Sorry. I changed it.

Anyway, my response was basically indicating that I'm unaware of evidence for training being able to improve visual imagination in a game-changing degree, my intuition tells that it isn't so, and so I'm surprised by cousin_it's remark. Although, strictly speaking, "I see no reason why it can't happen" communicates the same statement, but again with the opposite connotation.

Which makes sense. I guess my original comment was just a ping for "Is this an opinion?" but it did it in an confusing way. But I guess I got an answer, so it eventually worked. :P

Which is an example of exactly the kind of clash of overconfident beliefs resulting from different intuitive judgments that Yvain described in this article!

Haha, good point.
