What happens if your fundamental attributions grow up from proximate personal narratives into a social philosophy?
Perhaps one where you understand yourself as some worthy ingroup whose shortcomings are primarily functions of imposed circumstance, with the shortcomings of outsiders primarily being functions of their character failings?
(Yes, you can see that in your political opposition! Congratulations. I won't say it's equally distributed across political spectra, since I think it's plausible that there are camps which are more widely concerned about circumstance over individual character and addressing systematic issues that contribute to circumstance. But if you can't see some form of this in the political affiliations you identify with, then you may not have truly grasped the fundamental attribution error dynamic yet.)
