I would like to take this opportunity to briefly discuss open-mindedness and what it means. I say briefly because I recently stumbled onto a video that explained it more brilliantly than I ever could.
When someone who is promoting a paranormal idea, tells you you're closed-minded, politely inform them that this is a logical fallacy known as ad hominem. They are attacking you, the arguer, instead of your argument.
Don't fall into the same trap, as the skeptic, by dismissing these paranormal ideas out-of-hand by stating, "well, of course that person is wrong...they're stupid/crazy". You would just have committed the same logical fallacy the believer had committed.
Lets remember to keep an open mind about things of the paranormal, but not so open that our brain falls out. Be open, but be skeptical. I would say,
"I'm open-minded, but I need evidence, reason, and argument to be convinced that (paranormal claim) is true."
The following video makes this point beautifully. Watch, enjoy, and share with your friends.
