There's a difference between talking about science and actually doing scientific research. This forum is a great place to do the former, but limitations inherent to Internet forums make the latter extremely difficult, if not impossible. Ignoring those limitations is in direct opposition to the scientific method.
That's not my attitude. My attitude is that it's pointless to use logs as a prerequisite to posting a personal conclusion, since the logs are very fast and easy to fake. They won't weed out false claims.
Of course it matters that some people fake their results. That's why these threads are entertainment and not science. That's a limitation of the format (Internet forums), and there's nothing that can easily be done.
Nobody here has claimed that we are doing scientific research, where you got that idea god only knows.
The primary purpose of these tests is to check your own abilities. Sharing the results here is done primarily as a community gesture, and to spur conversation among people of similar interest. Again, the bar that we are choosing to set is that if you want to post an opinion, post your logs. The rest of head-fi is open to posting any opinion you want with no limitations at all (well, so long as you stay mostly positive when discussing sponsors, but I digress). If someone wants to fake the tests, that's up to them. It does nothing to minimize the rest of the discussion because this isn't a contest.
