My question in broader terms is "What is the importance of scientific references in answers on Cognitive Sciences SE". In this regard it has overlap with What level of citing references or sources should be required for answers?, but that post is getting outdated and doesn't answer my question in specific either, as I am specifically interested in what I should do with missing references in an answer in a role as reviewer when looking at answers (either inside or outside a review queue).
The point is (without claiming which is better or worse) that at Biology SE referencing is taken pretty seriously, and I have noticed that quite some answers at Cognitive Sciences SE get upvoted while there is no mention of any sources whatsoever. Given I regard myself not familiar enough with the guidelines of Cognitive Sciences, I often refrain from performing a review task on answers with no references from newcomers, the more when I am not familiar with the topic (I am a biologist).
Nonetheless, at Biology SE I often ask for a few references anyway if I have my doubts, even if the question is outside my area of expertise, because references are much appreciated by me, and others on Biology SE.
What about folks on Cognitive Sciences? Is asking for references (and hence commenting, maybe even downvoting, or perhaps even flagging when in serious doubt) encouraged too?
