I am currently reading a book that has some poor (IMO) science and it is a 'science thriller'. I had a question alone the lines of "can you believe this?" And was wondering how it would be taken. I wasn't planning on naming names but spending time here makes me more aware of some things. 

I was wondering if questions like this have a chance, or have a tag "World building fails" or something. Maybe asking for better ways to do it, or just better answers than the ones provided.

I have several examples from this book but the one I wanted to float out there has to do with a marine biologist grad student who made two statements that show the author misunderstands evolution AND Darwin. Partly I wanted to verify my own understanding and partly I wanted to point out a "what was he thinking" moment.

I started really paying attention when one character mentions that -25C = -87F and everyone is OK with that.

I wanted to bring it up here to see if something like this is OK depending on how the question is worded (as a "avoid these mistakes" section) And if it's OK how we want to do it.
