So, part I of that process. What do you think a genre trope consists of? Please provide examples.
My initial, off-the-cuff answer, is to cite Gardner Dozois who from time to time comments on "the furniture of science fiction." FTL travel, for example, or strong AI — story elements which are common to the (sub)genre in which they are found, generally don't require definition ab initio, and can be experienced purely in context.
I suspect this is a highly insufficient characterization of a "trope", however.
