I wonder to what extent personal compatibility is taken into account when making crew decisions. Do they interview each other and/or does NASA check to make sure they don't all hate each other before shoving them all in that sardine can together? I imagine most of them are pretty good at compartmentalizing and regulating emotional distress when it comes to things like misophonia but is not chewing with your mouth open a mission critical skill? Do they have strictly regimented bathing schedules so no one gets too funky. I gotta know what they all hate about each other the most.
