1. I am pretty far from thinking I am right all the time

2. I do tend to go on rants, but I always like to listen to what people tell me. Especially if I can sense that they think what they are saying is important.

3. Guilty.

4. No one is perfect, your english is probably better than mine for instance.

5. I remember reading about this once. It's kind of strange to have this kind of personality be disected in a razersharp scientific language since these people with this personality usually get described in a much more emotional way.

By that logic, every university professor ever is a pseudo-intellectual. I'm sure many would support that view, really.

I'll contest that an actual intellectual could well meet many of these criteria.

1) An actual intellectual may be right during the overwhelming majority of times. I'll also note that you have no way to determine if any individual on here thinks themselves to be right at all times; consider that many individuals will refrain from posting in a debate regarding a subject they are unfamiliar with- this behaviour can create the illusion that they think they're always right when it's obviously not the case.

2) When two people are discussing a subject, it is pretty typical for the more informed individual to talk more. And in this particular medium, how can you verify that one talks more than he or she listens? Even if someone is prone to a long-winded postings, one can't make the assumption that he or she simply isn't reading the other post. I know that I, and many others, read the entire exchange on both sides of a given debate before we post.

3) This is more of a personality and cultural trait than a measure of intelligence. Sometimes it's reasonable to substitute synonyms simply to be less repetitive. Furthermore, you have no way to measure whether an individual is doing so out of personal choice, personal preference, avoiding repetition, or legitimate compulsion.

4) I'm pretty sure just about everyone I've seen who has more than a couple hundred points has conceded a point somewhere; this one seems to be a non-starter.

5) This one may have some merit on this site, but it would take many observations across many debates to establish it.

From that, I can say with certainty that your diagnosis does not follow, as the limitations of this medium preclude you from being able to verify 4 of the 5 symptoms in question.
