I've gotten into the habit over the past 2 years or so of renting entire TV series on DVD, and watching them over the course of a few months. Always ready to put on my amateur psychologist's cap, I've noticed quite a few things. One thing that I've noticed is the near perfect combinations of personality types on the various Star Trek shows. To give the short version, the personalities of the various captains are perfect for the situations that they are put in over the course of the series - the by-the-book Janeway is the perfect type of captain for a ship lost without any support or structure to function in (she creates this structure), the calculating and knowledgable Picard is perfect for functioning in a fairly well known political environment (He knows the key aspects of every culture, and he knows the rules and regulations inside out, and can manipulate both with keen political effectiveness), and the obnoxious Archer is the perfect choice for stepping out into the unknown to build up an alliance (in his goofy and obnoxious way, he's the perfect conduit for garnering support - he's intuitive, sensitive, empathic, and trusting).
Furthermore, thier support staff always compliments them - the touchy-feely Chakotay offsets the overly strict and structure-obsessed Janeway, the logical Spock offsets the risk-taking Kirk.
All of this is interesting from a psychological standpoint, because in real life, the leader is hardly ever suited for thier environment, and thier support staff is as likely to be oppositional as complimentary - and one has to compliment the writers of these shows for intuitively creating the perfect character to lead in thier specific circumstances, and the perfect support staff to compliment them. Any of these captains put in any other captain's shoes would not be nearly as effective as the are in thier own roles.
So, although there is always talk of this "utopian star trek universe", all it really is is just a function of the right personality leading the right people in the right circumstances. This doesn't just go for Star Trek - You'll see the same thing in Stargate, SG-1 with Col. Jack O'Neil - although in his case he is a little less suited for the circumstances, but his support staff is nearly flawless in it's ability to turn any situation around. This would be contrasted with a character driven show like "Lost", where the personality clashes are one of the focal points of the drama, and probably a more realistic version of leadership in the modern day - regardless of how effective a leader like Jack Shephard may be, it would be too contrived if the people around him all had complimentary personalities. Of course, unlike Star Trek, or SG-1, the characters on Lost did not intend to be thrown together in the first place.
So, it is my theory that in real life, be it in business, the military, or whatever - if you can get the "perfect leader" for the situation at hand, and give them the "perfect" support staff, you can't lose. I am looking at this from a personality perspective - some situations demand a dedicated, rulebound autocrat who commands respect (I.E. Janeway), and others demand a flexible, risk-taking leader who interprets the rules to fit his needs (I.E. Kirk), or someone who is introspective, intuitive, empathic, and yet decisive (I.E. Sisko).
Oddly enough (or perhaps not), if you look at these leaders through the lens of the Five Factor model of personality or the Myers-Briggs Type indicator, you'll see that most fit the "High Openness to Experience" [iNtuitive, by the MBTI] (Except, of course, Janeway), which is ironic because in the general population that single factor shows up in only about 1 in 4 people, whereas all of the other factors are about equal at 50%.
Why is this important to note? Because in general, people with High Openness (iNtuitives) do not end up in positions of power - they tend to be very good at seeing the big picture, which thier superiors usually can not. This often gets them into trouble, and precludes them from promotions. So you are left with the Peter Principle - people who rise to thier level of incompetence. People who are close minded and detail obsessed promote the same. (There are many psychology studies done on the promotion or hiring of people who display similar personality traits - if I find one online, I'll post it.) So, in a way, the Star Trek universe IS a
utopia - because of the absolute ubiquitousness of open-minded people in positions of command.
And the problem on this planet today - the lack of open minded people in leadership in business and the world.
