I've had the privilege of knowing some stage magicians (people who do illusions, sleight-of-hand, card tricks, etc.). They're always very interesting people, always very smart, and always extremely cynical.
If you go to a psychic fair, if you go to a party with a Tarot reader or numerologist, etc., and you get a reading, be careful because there is an excellent chance that you are getting a reading from someone who does card tricks, cold readings, and mentalism. They give readings as entertainment while disguised as "real psychics" and they do not consider this to be fraudulent. They, in fact, consider "real psychics" to be frauds and they have a name for people who believe in anything occult: shuteyes. A shuteye, in their parlance, is a person so skilled at giving fake readings that they believe they're doing real readings. It's a bit of a backhanded compliment, that.
A fellow who does fake psychic readings for hire told me that he knew of a lady who did Tarot readings at local occult shops. She filed down the Death card by a millimeter on one edge so that, when cutting the deck, she could always cut the Death card to the bottom so that it wouldn't come up in the reading. This she did because she was doing readings for "true believers" and didn't want to panic or upset them so that they'd keep coming back and paying her. At least this friend of mine is upfront about the fact that what he's doing is purely for entertainment; he doesn't present himself as a psychic, but as a performer using psychic trappings. But this Tarot reader and many like her have no such scruples.
I'm not writing this there to increase cynicism, but it is worth noting that such people are out there. They consider what they do to be more valid than those who think they're doing a spiritual, magical, or psychic service. If you're getting readings of any sort, make sure you're getting one from someone who will give you the kind of reading you're actually looking for: one just for fun (which is absolutely fine, in itself) or one for guidance. And always remember that a person's worldview informs their values and their actions. What you think is truly important is utterly illusory to someone else.
As for me, I find the cynicism of the stage magicians to be going too far, but still a helpful lesson in keeping my wits about me and doing my best not to allow my attention to be misdirected by those who would take advantage of me. An honest stage magician will at least be up front about the fact that they're messing with your sense perceptions to amuse and mystify. Dishonest cheats of whatever medium — from the lowly psychic reader at a card table at the fair to a cult leader to an advertiser or political spin doctor — will only admit to what they're doing once there's no going back. Neither become a cynic nor allow your sense of wonder to be used against you.
