Scenario outcomes resulted by random chance more than logic
I think this movie had much more potential then what it turned out to be. Its biggest flaw, in addition to seemingly unnecessary relationship drama between characters, was that the logic, which the teacher praised, didn't dictate the scenario outcomes, but random chance did.
I think its pretty safe to say that in any scenario, it is better to select people with highest utility towards goal to achieve preferred outcome. Team of tech professionals, doctors, people with craftmanship and so on would generally be better choises if survival was the goal. But the scenarios run with those teams were failures not because of bad picks, but because of arbitrary decisions and random events that took place. In first, the group left one dude out, and it seemed there was no thought process behind that other than fear of violence. In second one, the randomness of no-one getting pregnant resulted into random event of violence which resulted in random survival of code dude and his random decision to kill all, despite otherwise pushing the team for decisions that would result to survival of humanity.
Then the last scenario with artists and other bunch in the bunker, they just didnt happen to have a scenario inside that would have required doctor or any other practical science -people who were left out. They survived, only to not even try to survive when their life support system run out. I recall the goal of the scenarios was that humanity would survive, not to have a good time while you can and then go out without fight.
Characters adding traits events when it pleased them didn't help either, it was like role playing game where players were also dungeon masters (or whatever they call the guy who narrates and creates the game environment).
