My experience was that being a sorta-halfway-decent-rationalist was part of what made it possible for me to do poly. I imagine there’s others like me, but they’ll already be rationalists (or have innately strong self-awareness skillsets and those may be good targets...). Others would have managed it using completely different sets of skills and I don’t imagine they’d be any more interested in rationality than the mean.
