I can’t take credit for the iCave term, but my concept of it is a bit different. I will exploit the term fully, however. The parallel that I draw is this: Media today often, whether intentionally or not, skews its presentation, and subsequently the public’s interpretation, of reality, in much the same way that the prisoners reality is manipulated in the cave. I would even go so far as to say that once a given person looks beyond what mass media says to what really is, that person may often be ridiculed in the same way an enlightened prisoner returning to the cave would be.
Now, thanks to the internet, this can happen at an unprecedented rate, and we all may become each others shadow puppeteers, with all the blogs, networking sites, and the like (such as Fluther) acting as our own iCaves.
Say I ask a question, here on fluther. Not knowing the answer, and operating with a trust in the truth of an answer i am provided (as many do), the answer presented to me would certainly be correct in my view, regardless of whether or not it actually is, and if someone where to argue against it, of course I would hold fast to my own comfortable reality, as opposed to a presented reality. A prisoner, in an iCave.
