now, if the psychological experiments had a 50% of the test subjects able to process new facts with ease while only 50% had a hard time, you could argue that one of the groups might have being TiFe users, or that they were less likely to resist facts. but this isn't the case - instead it seems like the vast majority of test subjects responded the same, which means it isn't likely to be linked to typology, at least not for aspects that stand around the 50/50 population divide.
the proposed solution (self affirmation drills) does support this might be the case, but it doesn't seem like they made a comparable study between the responses to new information in regards to neutral issues vs. issues with personal stances.
(they should have... are you bored enough to write an angry letter to their university's dean that they should get the research budget for a comparitive study? i'm not, but if you happen to have the time...)
