Then great, this is the proper next step, I wasn't positioning it as a document of truth, but an example of what 'appears' to be credible. Invite discussion. I wouldn't reply that "you cited a crap paper". How about "that's interesting; however, I see there may be concerns with its validity as pointed out by..." It takes time to investigate everything, and one shouldn't just stop when they find the answer they like.…
Dude. Cherry picking data renders any discussion of validity meaningless. It is crime against science. It's means your study is worth less than paper it is written on and that your reputation is essentially right next to earth's molten core.
Its quite easy to recognize, just see who funded the study and you see a trend of results supporting the funder.
Almost nobody takes the time to investigate a study. You are assuming the person knows the study is flawed to begin with.
How do you know the critique of a study is accurate? The critique deserves as much scrutiny as the original until it can be verified. Otherwise it would be cherry picking data to simply stop when we find an answer that fits our beliefs without doing the same investigation of its statements and sources.
