Hey Fr,
On a personal note I agree that psychology has not reached that rigorous level of proof demanded of some fields, but I suppose that is to be expected too. Study of ourselves is somewhat unique as compared with study of much else (i.e., I don't find it surprising that we have difficulty understanding our own behavior), but I also agree it's a valuable field. Likewise even if it's debatable, observing patterns of behavior in ourselves and others is something we people have a sort of knack for, sans the fuzziness of our ability to describe those patterns (plus human variance).
Secondarily many authors have written about the concept that extreme personality types may be successful in some areas of life due to the extremes, but as you wrote indirectly, there are usually some negatives as well (e.g., relationship issues, mis-understanding how the 'norm' perceives, emotional reactions or feelings that are extreme as compared with the norm including painful emotions, etc.) It may also be true that many people with extreme personalities do not want to change if it means giving up the positives.
A final related thought is that 'norms' may tend to evolve in societies because, on average, the norms are motivated by the benefits of getting along reasonably well with others, and cooperative settings (e.g., family, joint efforts like work, and so on). A simple example makes the point -
Most people agree in most societies that stealing is wrong. Some people do commit theft though, for the personal benefits, but even those who do steal tend to agree it is wrong if others steal from them. It's a norm then for a reason, not just arbitrary why that norm evolves.
Likewise the norms re: how we treat each other, even if not always spelled out, evolve for the same reason, and this is where the concept of a personality disorder comes into play. A few simple examples make the point:
Two people with an overwhelming need to be 'right' will eventually disagree.
Two people with an overwhelming need to be the center of attention will eventually find their desires at odds (only one can be the center).
Two people who lack empathy for others will eventually step over each others boundaries.
Where most people have roughly adopted the norms, the extreme personality types may enjoy the benefits of the extremes, but also find the extremes difficult to live with in others. Hence the wording 'disordered' thinking.
