I think this sub-logoi is pretty exceptional; perhaps it is attracted to more painful experiences:
Mixed harvests on Venus (though nearly all positive except for two individuals; EDIT: Ra terms what occurs on Venus not a mixed harvest because the two negative harvests were wanderers) and Earth. Mars' 3D civilization destroy themselves and render the planet unviable for life (think this was Ra, but might be someone else). Maldeck's 3D civilization destroy themselves and destroy the entire planet. I'd be surprised if this sort of situation was par for the course in terms of solar systems.
