There's different levels of investigation.* The meme appears to
   assume much about the style of investigation.* That's where it
   gets into philosophy... although discerning the nature of Truth
   really never leaves the philosophical schools; it just finds
   application within our cultures, depending on our philosophical
   'bent' at the time. Actually, there's everything wrong with the
   Meme really. What's the nature of the Investigation?* There's
   several methods of inquiry; experiential, philosophical,
   evidence, reason, consensus, opinion, hypothesis, thought
   experiment, mathematical, linguistic, subjective, objective,
   historical, heuristics... . What's rejection?* Is it denial?* Is
   it stopping because one has gone as far as someone feels they
   can using the tools they have at hand?* At every stopping point,
   there seems to always be someone else who says, "You didn't go
   far enough!" (not a bad thing in my opinion, although sometimes
   annoying to be on the receiving end of it!) To me, "refuse to
   investigate" in the context of this Meme implies, "Looking at it
   from my perspective".* This Meme could be used from any ideology
   who is arguing against another ideology. [hence, why I find
   ideologies helpful but splitting up the world into "ideas vs
   reality" Platonic style can be annoying sometimes when ppl
   forget that we live within a culture with a history and a lot of
   assumptions about reality go unchecked, making some of the
   argumentative Bumper Stick Memes seem... not very well thought
   out... just clever]
