A philosophical zombie or p-zombie in the philosophy of mind and perception is a hypothetical being that from the outside is indistinguishable from a normal human being but lacks conscious experience, qualia, or sentience.Wikipedia
If they are indistinguishable by definition then I cannot even talk about them because that implies I can distinguish them, which by definition I cannot.
It is possible to distinguish them, and I firmly believe they exist outside thought experiments, and arguably in large numbers. They move through society seamlessly and there are some situations when they “come out”.
They are easily spotted by using techniques that induce widespread imitation of preferences which are rare. e.g. LGBTQQIAP people are rare (if they weren’t rare we wouldn’t be here), but by claiming there is virtue in “coming out”, more people will “come out” than ought to. This is because those extras are p-zombies. They do not have real preferences or even desires. They merely imitate what others do.
I would argue most of religion was designed to keep the p-zombies in check from devouring the rest of us. And in a democracy, manipulating p-zombies for votes is the key for everlasting consent of the governed.
p-zombies have no moral preferences, they will do what the moral leaders preach is cool. In modern society, the moral leaders is the media-academic complex. Religions have lost their dominance over p-zombies.
Thus we have actors raising their children to be transgender, or pretty much anything that helps them signal their holiness/piety.
The whole world might be a test, for us real people to see how we handle life among the p-zombies. If I were a creator of sapient life, I would make newly sapient beings live among the p-zombies to see how they handle it before letting them live in the “real world”.
Beware of anything that involves rarer preferences but widespread adoption. That is the test. If you can see through the illusion created by the test, you are fit to come to the “real world”.
e.g. I think this who climate change and eco-everything phenomenon is a test to see who are the p-zombies. The powers that be are tracking it using social media and the Internet.
