All Fives are introverts
WRONG. Though most of them are (I think, 83% of them). Pres Fives and Social Fives are usually introverts, but Intimate Fives may be extroverts.
All Fives are quiet or reserved
WRONG. Though most of them are, some of them are pretty much outgoing. Again, I'm mostly thinking of Intimate Fives. For example, I'm not comfortable about being quiet.
Fives lack empathy or kindness
WRONG. OK, us Fives aren't hippies, but we're not ****** or Stalin. Fives are still more friendly than Sixes or Eights.
Fives are unassertive
WRONG. Again, Fives aren't ****** or Stalin, but usually don't really allow others to take them for granted unless really fucked up (i.e. ego Level 04 or less). They aren't going to join gangs, but are still able to defend themselves socially.
All Fives are soft-spoken
WRONG. Some Fives may be pretty loud. For example, my voice is like I'm E3.
All Fives are absent-minded
WRONG. But Sensing Fives are unfrequent. For example, there are cases of SLI's.
Fives are unable to lead others
WRONG. Fives are quite frequent in businesses. They're not pushy, but are usually bossy and pragmatic, like Ones or Threes, except that they have a low energy level, and therefore, they don't drive others. Most people find more comfortable to be led by Fives than Sixes or Eights.
All Fives are reclusive
WRONG. They may look reclusive because they lack motivation. This includes motivation to expand themselves socially. This may lead to actual reclusiveness. But they're not "reclusive" by their nature. If they're not motivated for non-physiological reasons, they usually remain withdrawn.
