Common Stack Network policy is to embrace non-Googlers. The Stack Exchange wants to be a place Google sends folks, not a place that sends folks to Google.
Unfortunately, many sites and some of our users feel the downvote reason "does not show any research effort" is synonymous with "did not try Google/Wikipedia."
While obviously there's no way to control folks' voting habits--and there shouldn't be!--I think it's useful to establish where lit.se hopes to come down on this subject as a community. Specifically:
If we embrace non-Googlers, what level of effort is sufficient for avoiding mass downvotes? For example, on scifi.se they determined reading/watching material is not necessary effort in order to ask questions about it. If we adopt that, then "Did not read the book before asking" isn't a reason to downvote.
