Interesting. It's true that if I say something, I believe it to be true or well, I wouldn't be saying it! But I would never mean to imply that my opinion on something is worth more than anyone else's opinion (if roughly equal experience/expertise in the area). That's why all the hemming and hawing and imo's. Do Fi users say things they don't believe are true? That doesn't make sense to me. I must be misunderstanding you.It comes from experience and observation. The fact that the judgment is often expressed in a subtle way to maintain harmony does not mean that it is not there. Strong Fe users are judging all of the time whether you know it or not.
Is it maybe that....Fe sees it as many opinions, with a "best" answer somewhere (note: not necessarily its own answer), while Fi sees it as many opinions, with no "best" answers anywhere?
I'm more interested in the second half - why is something automatically suspect because people agree with it? Is there a sense that it's inauthentic and has been formulated specifically to please people, rather than stating the truth? Given a random statement by an Fe user that 75% of people agree with: If a Fi user agrees with that opinion, is it because it's popular? If a Fe user agrees with it, is it because it's popular? Does people agreeing with it alter the accuracy of the statement, and if so, why?I don't see it as much different but I'm sure some artful application of Ti would find find flaws in the nuances of the wording. It's close enough in my opinion.
Your logic is sound, so I'm not sure why I'm still feeling myself disagree. Nobody really likes to think they would participate in mindless conformity, even though the vast majority of people actually do so in studies (surely not all Fe if we assume the proportions are roughly 50:50 - what they are I have no idea). Even if an Fi user firmly believes something, it doesn't mean they'll speak up about it. Even if an Fe user considers the feelings of the group, it doesn't mean they won't speak up about their objections in a polite way. So, I'm not sure I've seen evidence in my experience that the theory here actually pans out in real life.Fe users generally value harmony and group values. Fe is focused on the object (the feelings of others). Fi users are focused on what they personally feel is important or to the extent something is good or bad. It is their personal appraisal based on their own beliefs, sense of integrity, right and wrong, etc. It is subjective - it comes from within vs. influence of the object. Therefore, by definition, it is less likely to be susceptible to group think/feelings.
Just trying to increase my limited understanding here. Not trying to defend Fe or attack Fi or anything like that.
