Probably people who are curious and want to learn how the universe really is, who climb to the highest levels of Perry's scheme of cognition, who use Sagan's baloney detection kit, rather than supernatural and unfalsifiable excuses, to understand the cosmos. It's part of the scientific method and great to learn new things, not mistakes but data for next experiment, and big claims require big proof, like defending a thesis should require. We are all waves of one ocean made of stardust, observing the universe, conscious elements billions of years old. DNA that survived all the extinctions so far, on the one habitable planet, and nothing to rescue us, but human cooperation.
If you want faith, it must allow room for doubt and mystery, rather than twisted to demand certainty and remain in Perry's low levels overall. They could study the neurochemical ways high-control groups hook people and keep them with unhealthy shame/blame/guilt, threat of exile, conditional belonging, solution for invented problem, punish/reward cycles, and maybe choose to escape. Good luck!
Perhaps everyone should have seen that the liberty and justice for all was not true from the start. Yes, better than others at times, but still so much violence, betrayal, lies, brutality, etc. which was hypocritical to the supposed values, others they failed to do: turn the other cheek, help the needy and outcasts, first will be last, love thy neighbors...
