Generational ship problem again:
Earth, far future: Generational ship left Earth for 20 generations long (600 years) voyage to another system. The ship is well built and even the people survive on the ship and make it to their new home.
There is one assumption which stroke me: One cultural norm has to be present for the voyage. I call it "Hobbit mindset":
Our ship is the best place to be. Why going somewhere else? We have everything we need. Home is best place to stay our full lives.
The above mindset is best portrayed in first Lord of The Rings movie: The hobbits enjoy being in the Hobbiton and do not care about the rest of the world. I believe that mindset is exactly what you need to sit down on ship and wait to get to your destination.
However, when you arrive, you need sudden mindset change to "Wild West mentality":
Oh the opportunities! The places to go! The resources to use and harness! Lets go face the wild!
Again, the above is best portrayed in most classical Western movies.
The problem is obvious: Is there a way to let people have one mindset for 600 years and then completely ditch that mindset for another?
