Based on my personal experience, there seems to a correlation between skeptical thinking and science fiction. I attend functions of a group of skeptics, sometimes physically at local venues, and at other times online with people around the world and I find that a large number of them are aficionados of science fiction and are knowledgeable about the minutiae of those stories.

Recently I created some mild astonishment within this group by saying that I had never actually watched any complete episodes of favorites like Star Trek, The Twilight Zone, or Dr. Who. I knew about them of course and had read about them and seen the odd clip of something from them. It is not that I avoid them. I do read the occasional science fiction but had never had any great interest in seeing science fiction on TV or the big screen. This surprised others who seemed to expect that with my science background, I would find them appealing.

One thing that had always puzzled me were the Daleks, the evildoers in the Dr. Who stories. They seemed to me to be laughably comical and totally not frightening. Eddie Izzard shares my puzzlement as to what the creators were thinking when they created them as conical objects with flat bottoms, like pepper and salt shakers, who moved on wheels and had weird appendages where arms would be.
