It's also equally important to note that sissy limitations in one's ability to think outside of the box != 'open-minded'. As I stated in another thread this morning, the irony of fearing the unknown and only considering the 'known' is that you think you are somehow more open, flexible, sane, and intelligent than the rest of us who study, analyze, and embrace possibilities of the unknown with fearless vigor.
The video example is too simple. The guy that sees the lampshade moving and considered other 'out of the box' possibilities first, is not necessarily close-minded. Looks like he may be uneducated. My first consideration would have been the 'knowns' around the room, with particular attention to the heater below the lamp where warm air is rising.
If the guy is ENTP, then he's open-minded by nature.
(Clearly, the guy in the vid that missed the heater running right in front of him, isn't ENTP. I'd like to believe an uneducated ENTP would at least wonder if the running heater played a role.)
