That seems crazy. There are like 10 people in space at any given time. The idea that we might have sent someone mentally unstable given that we can be that selective is mind blowing. How in the world can you qualify for this if you aren't the best of the best of the best?
I don’t see mental instability as an independent defect but as a byproduct of some of the long tail aspects needed to be the best of the best. To put another way, many people are motivated to fill a void, that same void can cause mental instability.
