a word with remarkably overt anti-epistemological connotations.
Really, I see it as describing a family of genuine failure modes that people trying to be "scientific" often fall into. For example:
a) attempting to argue by definition that something is "science" and therefore right.
b) arguing that just because some evidence isn't scientific, that it's not valid evidence.
c) insisting that the results of the latest scientific research should are right, despite results in the relevant field having a very poor replication rate.
In case people try to argue that these errors rarely get made, here is a comment by Yvain with 22 karma that makes errors (b) and (c).
Can you point out where Yvain makes those comments that you think violate b and c? Reading that post it looks to me like Yvain's points are a little more nuanced than that.
Note incidentally that while you might be able to use the word that way, the vast majority of people who use it seem to use it in a way closer to what sketerpot is talking about. If one interacts at all with either young earth creationists or homeopaths for example it often doesn't take long before the term is thrown around.
