Heidegger would say that all humans are thrown into existence and into circumstances that they did not choose. In some sense, we are currently on a large spaceship, and I assume some mission chosen for us by our predecessors.

"Sorry for the inconvenience" -- Hitchhiker's series

To be fair, no human born on our current Earthship asked to go on our current mission.

What's our current mission? "Keep society running" and "don't fuck up the planet" don't seem to be going super well, but that's just my cynicism talking. I need a nap.

I think we even today have enough propaganda and religion experience to make sure that the next generations would be happy to see themselves as the chosen ones, etc.

(small case in point - back in USSR we were happy that we were born in that wonderful country USSR and not in those decadent dangerous inhumane capitalist societies of the West where people were forced to struggle everyday to avoid becoming one of those numerous hungry homeless filling to the brim the dirty decaying cities of the West which they were showing us on the Soviet TV while we were supposedly on a mission to build better/higher/ideal society consisting of a new better entity "Soviet man" - "The Soviet man was to be selfless, learned, healthy, muscular, and enthusiastic in spreading the communist Revolution." https://en.wikipedia.org/wiki/New_Soviet_man - note how the first 4 qualities work for interstellar, and they are pretty common among various other ideologies and religions, and the specific target for the 5th - for the enthusiasm - is just adjusted according the specific ideology or religion, and "spreading human civilization" wouldn't be even half-bad like some others out there)

Um, did anyone actually believe that in practice ? Of course, if you asked them, they would say so, to 105 socialistic percent, comrade!

Bur personal and in private, it was very different.

Of course the religious fervor of the first post-Revolution years wasn't there say in 197x, yet so many people in Russia have during the last 30+ years been wanting back to USSR. The propaganda shapes your brain, especially if they hit you while you're young.

>But personal and in private, it was very different.

Deep down unfortunately the ex-Soviet people, me included, are damaged goods :)

Provided the first generation volunteered, I expect the second generation would still be indoctrinate enough to the idea and mission to be fine, but the third generation would definitely be stirring some shit up.

Change the programming and go back. I wonder what reaction back here would be...

Not really possible for many mission profiles (e.g. if using target system star for braking or pre-programmed beamed propulsion) - so often that would not be an issue. ;-)

Not really. That would just be the way life is to those people. Showing them videos of how people lived on a planet would be like asking them to imagine how a caveman lived.

If they did rebel it would probably be more along the lines of reaching the target inhabitable planet and refusing to leave the ship. Just grab enough material to set a new course for the next one and keep going.

The next set of rebels would be the ones who actually fulfilled the mission.

Living on a ball of rock with no climate controll ? Are you insane ? Do what you want, I'll go back to building that new custom Stanford Torus we just got started last cycle. And don't call for help when it inevitably starts raining!

So you just make it so they don't notice they are on an interstellar mission - sorry, to board the train to the capital you still need to fill in form XB1, but the officer who can fill it is on vacation (in the capital and the trains totally go somewhere!) - please come next cycle.

Basically an unhollo combination of Kafka and Truman show, keeping the community stable until arrival. :)
