Xenophon: Well, those people need to read the bible a little better, as the bible does state that magic is real, and provides examples (bolded so you don't have to read the context if you don't want to)
8 The Lord said to Moses and Aaron, 9 “When Pharaoh says to you, ‘Perform a miracle,’ then say to Aaron, ‘Take your staff and throw it down before Pharaoh,’ and it will become a snake.”
10 So Moses and Aaron went to Pharaoh and did just as the Lord commanded. Aaron threw his staff down in front of Pharaoh and his officials, and it became a snake. 11 Pharaoh then summoned wise men and sorcerers, and the Egyptian magicians also did the same things by their secret arts: 12 Each one threw down his staff and it became a snake. But Aaron’s staff swallowed up their staffs. 13 Yet Pharaoh’s heart became hard and he would not listen to them, just as the Lord had said.
14 Then the Lord said to Moses, “Pharaoh’s heart is unyielding; he refuses to let the people go. 15 Go to Pharaoh in the morning as he goes out to the river. Confront him on the bank of the Nile, and take in your hand the staff that was changed into a snake. 16 Then say to him, ‘The Lord, the God of the Hebrews, has sent me to say to you: Let my people go, so that they may worship me in the wilderness. But until now you have not listened. 17 This is what the Lord says: By this you will know that I am the Lord: With the staff that is in my hand I will strike the water of the Nile, and it will be changed into blood. 18 The fish in the Nile will die, and the river will stink; the Egyptians will not be able to drink its water.’”
19 The Lord said to Moses, “Tell Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt—over the streams and canals, over the ponds and all the reservoirs—and they will turn to blood.’ Blood will be everywhere in Egypt, even in vessels[a] of wood and stone.”
20 Moses and Aaron did just as the Lord had commanded. He raised his staff in the presence of Pharaoh and his officials and struck the water of the Nile, and all the water was changed into blood. 21 The fish in the Nile died, and the river smelled so bad that the Egyptians could not drink its water. Blood was everywhere in Egypt.
22 But the Egyptian magicians did the same things by their secret arts, and Pharaoh’s heart became hard; he would not listen to Moses and Aaron, just as the Lord had said. 23 Instead, he turned and went into his palace, and did not take even this to heart. 24 And all the Egyptians dug along the Nile to get drinking water, because they could not drink the water of the river.
There are a handful more examples, but these should suffice.
EDIT: Although, actually Iatros is right in that the majority of people, including christians who "don't" believe in magic, do believe in paranormal/supernatural stuff to some small degree (usually small enough that it gets called superstition, though). Also, as Iatros says, it is a skill that needs development; we wouldn't magically become kung fu masters just because the majority of people believe in kung fu, right?
I think most people only belive in things like Jesus' ressurection 10 commandmends and all "important" stuff in Bible without even reading it completely (or at all) all their lives and just go to church etc (which by the way has nothing to do with religion and only exists because priests took advantage of peoples fears to profit for thousands of years already) celebrate Christmas (in wrong time of year and wrong way). Or they dont even belive it and just do all that from fear of punishment.
Also having trouble beliving everything from a book written 2 thousand years ago exactly as it is written (no offense), in beginning it was all hear-say until they started writing it down and a lot could have been lost in translations from languages back and forth for 2000 years of languages developing changing and such (hebrew latin english etc) a lot could have been rewritten as only people who were capable of writing for hundreds of years were only privilaged ones (rich...) who may have wanted to keep important information such as how to levitate something or anything leading to such power or existence of such a power itself a secret if it was even written in the first place.
And thats just Christians, there are also atheists agnostics who only interfere with psionics if thats how it works (everyones beliefs effecting abilities) and a lot of other religions and personal beliefs people have which I dont know if they include psionics as something possible or not and even people that do can belive psioinics are something hard to do and even further weaken your abilities near themselves. Maybe even conflicting beliefs between two people that belive and practice paranormal can interfere with each others abilities...
Also I didnt say everyone would instantly be able to do 'magic' if everyone belived in it, I said it would be a lot easier though, especially if they saw it happening all around them all time. (not to mention advantages in training from better understanding of how paranormal works).
About kung fu analogy.. kung fu is just a different way of doing something we already know how to do (move body) in complicated and effective ways. In paranormal (to oversimplify) you move your soul, which most people dont even know exists or how to control it their entire
lives or even comprehend how unlike anything they have ever expirienced it is.
In another oversimplified explanation its like people who live in 2 dimensional world trying to understand a 3 diminesional object without leaving 2 dimensional world and even that is not as a big of a difference as soul is to what they know about (physical).
Its easy to manipulate something obvious to you (body) compared to manipulating something you cant even imagine (soul). But if soul were "obvious" to people maybe it would be as easy to learn how to move your soul as learning how to move your body.
Kind of makes more sense now why people sometimes leave civilization to learn this stuff...
You haven't developed your imagination enough to engage confirmation bias.
What do you mean? I practiced psionics before and am still not sure if I did anything or not. My imagination might be a bit... weak as I was trying to understand how it all works without practicing enough for years... now I feel like Im stuck not being able to do anything until I "crack it" or someone levitates something in front of me to restore beliefs I dont even know I am missing. Not sure if one lifetime is enough for first option though... and more Im trying to "crack it" more difficult it becomes to practice (at least for now)
