      Oh, but I think he should be at the top of the list of people who go first. I’m sure he and 21 of his billionaire friends will surely pull through.

      It said those with agreeable personalities would last a lot longer than those who are more neurotic. I think that disqualifies him.

        Which I don’t get. If I am going to be so close to death all the time I want to be with people who have a healthy level of caution.

          If 22 people are stuck on a planet together and need to depend on each other for survival, having the ability to get along with others is pretty important. Being agreeable doesn’t mean a person can’t also be cautious, they’ll just handle disagreements differently. I have to assume they won’t be agreeable to the point of allowing themselves or others to die over it.

            Agreeableness is one of the 4 big personality traits as is Neurotic. There is a reason why it hasn’t been selected out in human beings. People who expect bad things can prepare for bad things. The worst projects I have been on have been ones where everyone loved one another and diligently “and then” every rubbish idea. You need different outlooks to survive and flourish.

            I don’t know this seems a lot like work. We have sales guys who shot from the hip, are friendly with everyone, and will promise the world. And you have engineering pulling their hair out about the slow motion disaster unfolding. Together things get done.

      I don’t think the bare minimum of people creating a self-sustaining population can afford to be monogamous. Though it doesn’t take many generations before that can start, 2nd gen might even be able to, assuming 1st gen has enough kids.

      I’m sure the “computer-savvy” nephew that came along to the colony can do the designer’s work, a lot cheaper too

    I remember reading somewhere it was around 500-1000 for a sustainable human colony to begin. Did we get better at avoiding Hapsburg Jaws?

      I was wondering the same thing before reading the article. This is for a 28 year mission, and doesn’t include setting up the base, or power and water supply.

      I think that number comes from long term genetic diversity issues. Some rule in biology about inbreeding depression came up with it

      If it’s basic generic viability I’ve always heard 30-60 though I couldn’t name a source for that.

    Does playing RimWorld count as running a simulation? Cause managing 22 people is too much trouble, unless a few might just be there in case the crops don’t do well.

    And then you wonder why it specifically states “no more…no less …”

      Iirc, the Matrix used that same number for determining how many humans to leave alive outside of the matrix so that the community wound be self-sustaining before they were able to ramp up breaking people out again.
