Notably absent from this write-up:
- effect size and significance for brain damage in terms of affecting those personality/cognitive characteristics
- how those personality/cognitive characteristics are distributed among the general population
- how common such brain damage is among the general population, or how much cognitive inflexibility/lack of openness can be attributed to brain damage
- and by extension how much variation in fundamentalism in the general population can be explained by brain damage
I'm guessing that with that information, you would not conclude anything close to "fundamentalism is brain damage".
But maybe we're still a step closer to finding a cure for fundamentalism
