Ask Slashdot: What kind of societies will the first Mars colonies be?

nyri writes: I'm making a two-part study in what kind of societies humans will build on Mars when we start to colonize the red planet. In first part, I'm trying to approach the question sociologically as rigorously as possible. Sociology being what it is, this also includes informed speculation. So, what does Slashdot think: What sort of colonies will humans for to the red planet? How large are they? How they make decisions and select their leaders? What kind of judicial systems they will use? What happens if a colony population grows larger than they are able to sustain? Will they be religious and if so, how? How their internal and external economy works? And so on...

A second part of the study is a psychometric study to find out what kind of personalities will be probably present in first colonies. I also encourage you to take the survey.
