>why this isn't more commonly known among people who call themselves rationalists

because most of these people do nothing else but writing blogs about rationalism. Same reason university tests are sometimes so removed from practicality compared to evaluation criteria in business, the people who make them do nothing else but write these tests.

I suspect if you put some rationalists into the trenches in the Donbass for a week they'd quickly have a more balanced view of what's needed to solve a problem besides rational contemplation.
