I don't even know what you're trying to illustrate with those links. My point was not that bad science doesn't exist, it certainly does. But Feynman did not have this nihilistic view of knowledge, he believed very firmly in the ability of science to deduce truths about the physical world and that there is objective truth.
Sorry to dwell on this, but this is not a nihilistic view, this is what's called the Pragmatic view of truth and was expounded by 20th Century Chicago School philosophers like John Dewey. Feynman was oft quoted as being a pragmatist, and a key tenet of pragmatism was embodied in one of his quotes:
"We never are definitely right, we can only be sure we are wrong."
In this fashion, we never hold objective truth in the Platonic sense, rather we accumulate knowledge that explains how the world works.
Does fellatio in fruit flies improve sexual reproduction? One study suggests it does. The problem we face now is that a substantial portion of people, including many very well educated folks who would claim to live scientifically-based lives, say "That's amazing!" and run and tell their friends this hilarious new "fact" they've learned.
Unfortunately there are plenty of these new "facts" people learn that are much more than novelty and lead to public policy or destructive dietary changes cough fructose cough.
We could all use to be a little more skeptical, pragmatic and curious in our lives.
