If you only send to space people whose dream already was to go to space, of course they're going to have a strong reaction when they do. That's like observing that Olympic athletes have strong reactions when they receive the gold medal and calling it "the Olympics effect".

I think you're wrong. Because otherwise articles like these would be either unlikely to exist, or we have much more spacers than it is known.
