That's a reasonable question. In general, it seems like there's a broad notion here of what is relevant to "rationality"- and many users see issues in science of general interest as connected. There are also good reasons to see fundamental physics as potentially connected because it connects closely both to issues involving the Fermi problem as well as to issues involving anthropic reasoning. Examples of potential failure modes of the scientific community are also relevant (although our prior should almost universally be that no serious failure is likely to be going on).
