I like looking at criticisms at theories I particularly enjoy,
   because to me, it is like what happens when I want to buy a
   product. I'll give an example:

   Many years ago, I wanted a cheap, good laser printer with all
   the right specs. [this shows you how long ago it was] I looked
   up the specs, read the reviews, and everything seemed great, by
   the numbers.

   There were a few quibbles but overall, darned good.

   It was everything I thought it was. Until 9 months later.

   Then it started getting a line running through each page. Then
   another. Then another. It wasn't horrible and being a cheap
   printer, how much could I expect?

   But still, I was furious! It hadn't even been a year and there
   was the beginnings of flaws, even though I kept the thing in
   perfect working order!

   So, I went back to the reviews of this 4.5 star laser printer
   with thousands of reviews, great use of paper and toner...

   ..and this one criticism popped up in a few of the reviews:

   "mine caused a faint line to appear that wasn't any big deal
   after I had it for a year" - from a 4 star reviewer.

   "Its a great workhorse printer! Despite the occasional ghosting
   that began to show up, the print was dark and legible and you
   could hardly notice it."

   and things like that.

   So... it was there right in front of me. I just chose to ignore
   them because, statistically, everything else was grand. I was
   forgiving of a few flaws when I bought it, and so were the
   owners.

   But had I listened more carefully, I wouldn't have bought it.
   They were forgiving of the little ghosting, but I wasn't. The
   fact that a few people made the same minor complaint - even if
   they were dismissive of it as being important - should have
   clued me in to, "THERE MIGHT BE SOMETHING HERE!"

   But they weren't screaming it. The clues were very subtle,
   nearly hidden from view. They were painted over by the 4.5/5
   star reviews, the rest of the long reviews that were
   overwhelmingly positive - in fact, almost entirely positive.
   Yet, it's something that was important to me. Like them, I just
   learned to live with the flaw, but with every page that popped
   out of that printer with the little thing grey ghost lines, I
   was strongly reminded of one key thing:

   The more you agree with something, the HARDER you *must* search
   for the flaws... and see if something that may be important to
   you personally, may turn out to be a problem... if you want to
   prevent future disappointment that you are presently blind to.

   Hard to put into practice, but very much worth the effort.
