EA Topic Suggestions for Research Mapping?

I'm considering doing another pilot "epistemic map", but I'm trying to decide what topic or set of research questions I should do it on, and am thus soliciting suggestions.

Whereas my last pilot/test map focused on the relationship between poverty and terrorism (and the associated literature), I want to do this one on something EA-relevant. FWIW, I think that epistemic mapping would probably tend to be most valuable for topics that are both important and unsettled/divisive (but progress still seems possible); secondarily, I think it's also probably more valuable when the topics are dynamic (e.g., assumptions or technological capabilities may change over time), have lots of interconnected assumptions/arguments, and/or have a non-small literature base (among a few other considerations). Additionally, it is probably more practical to try to address a specific research question within a field (e.g., "does poverty lead to an increase in terrorism"?)

Some of my ideas thus far have been the controversial Democratising Risk paper and its claims/context (or something else within the X-risk literature), the Worm Wars debate, something in biosecurity (e.g., the potential value or risk of certain emerging technologies), or maybe something about AI (e.g., the viability and impact of small-sample learning). But I'd love to hear any other suggestions (or feedback on those ideas I listed)!

(Edit 3/6/2022: this post was updated to clarify that the intended focus is more on mapping the research related to specific questions within a field, rather than mapping an overall field)
