There is a potential to have a separate version of every question or topic that focuses on: scientific evidence, research, or some other reference.
Shouldn't this get handled in the OP's evaluation of the answers? Answers that include support should be encouraged.
Is this a work-around to appear to avoid a flame war? "What are some references to scientific evidence supporting that Java is the greatest language?"
Example: This question wants Scientific Evidence about variable length.. Another just asks can variables be too long and does give specific examples which I hope the focus is not on the particular variable names themselves.
