"Flinching away from truth” is often about *protecting* the epistemology
Well, it applies to the article... but also to cases in which one variable is actually related to the theory, not as in falsely related this time. You do reject the new information to protect your theory,
To the second point: What makes you think that? And on which point do you think it acceses? Do yout think OCD prevents people from incorporating new information in general, or does it increase the chance of two variables ending up in "one bucket" that are not actually related (probably not in general, but in one aspect, like cleanliness or such)?
