Context and viability are the prime key and as far as Luke wanting to toss out any Readers in his audience... I doubt it... he was brought out into the show biz world by Readers... Myself and Kenton being near the top of that list. I think he's just saying what's commercially and politically "correct" for the moment... but only for the moment. The world is waking up to the fact that
assholiness has gotten out of control.
The other side of things, if you're worried about people thinking you one of those evil Psychics that lie and cheat... there are far more psychologist in prison for lying & cheating and getting folks addicted to harsh drugs than Gypsies... something to bear in mind whilst passing moral judgment around in such wholesale a manner.
Bob Cassidy, Kenton, Richard Webster, Ron Martin, John Riggs, Jon Stetson and an armada of other TOP RATED LIVING LEGENDS of Mentalism all refer to ourselves as being "Psychic" and we're mature enough to not only know what that means, but to explain it in a way to our patrons that helps them accept a more analytical perspective on things vs. the fantasy and lore that so many pass around. Sadly, those making claims that they can read folks due to study in NLP or Body Language, etc. are just as big and bold a LIER as they insist we evil and cold hearted psychic are... same holds true with our Psychological Magician types... you are applying the very same ALLUSION to the situation... same product, different flavor. But please understand the ethics as well as the obligations are one in the same.
OUR JOB as
PSYCHIC ENTERTAINERS (which is what we've been known as for a very long time... even before I was born)
involves the cultivation of belief from the patron. If that isn't your goal you are a magician, plain and simple! Trying to have things both ways ruins this craft and limits your ability to pull it off properly and with the optimum sense of advantage. This is especially true if and when you are "picking up on" information or vibrations from your subject... to attempt to twist things in any direction but said idea, is to castrate yourself as a performer (not my opinion alone... go back and read your Bob Cassidy and any one of the others I've mentioned)
So yes... we must entertain them but we must do so in a way that enchants and solicits that investment of belief.
True Mentalists rarely worry about those "sure things" you were talking about BobbyCat. You'll never learn to trust your gut until you jump into the pool and start doing so boldly, bravely and blindly. This is why we have so many skeptics in that few really are willing to take a leap of faith and just do it... their analytical mind is too busy distracting them and keeping them away from the golden apples.
You "Practice" Readings by doing them.... you see strangers as you wait in line at the store, you do a short palm Reading or any number of other circumstances...
YOU open the door to share your impressions and in so doing, learn from their reactions. There's no cheating, no stacking the proverbial deck...
there's just doing... as Yoda would say.
