In academia, common knowledge does not require a reference.
Teaching a method behind an effect in a public, is what is labelled as exposure unless it is your own effect which you reserve the right to teach. That is common knowledge in Magic. Breaking magic, does teach some classic illusions that involve science. So yep, that would be technically called exposure.
However, being of the opinion that everyone is guilty of some level of exposure and that you gotta chill about it unless a commercial effect is being exposed...I would say I dont mind.
Your post is a little hard to read because I'm guessing English is not you native tongue. I'm guessing you mean public forum. The rest I'm not sure what you mean since again it is hard to read. Now...
Magic methods are not common knowledge. They are a secret. Part of the working knowledge of those who are part of the brotherhood of magic. Even within magic, some of these workings are not shared with other magicians to keep them out of the hands of other and from being exposed.
Since you want to try to use academia to come off as having an educated stance on this, lets see what MIT has to say about common knowledge...
"Broadly speaking, common knowledge refers to information that the average, educated reader would accept as reliable without having to look it up. This includes:
Information that most people know, such as that water freezes at 32 degrees Fahrenheit or that Barack Obama was the first American of mixed race to be elected president.
Information shared by a cultural or national group, such as the names of famous heroes or events in the nation’s history that are remembered and celebrated.
Knowledge shared by members of a certain field, such as the fact that the necessary condition for diffraction of radiation of wavelength from a crystalline solid is given by Bragg’s law.
However, what may be common knowledge in one culture, nation, academic discipline or peer group may not be common knowledge in another.
Lets look at that last part right there. What is common knowledge in one peer group may not be in another. So no magic is not common knowledge to the average educated reader. Why would they know the working of sleight of hand? So while most methods are common knowledge to magicians who are well studied, they are not known to the general population.
You can have the opinion that everyone is guilty of exposure and well, it is not an opinion you can back up. I don't have to chill out about it. You can say you don't mind, but there is a very large section of the magic community that does care. There are tens of thousands of us who are members of the IBM, SAM, Magic Circle, Magic Castle, ect. ect. that fight the exposure of magic in open public forums.
I DID NOT SAY MAGIC WAS COMMON KNOWLEDGE.
Yes, I missed the word "Platform" after public but the rest is grammatically correct so do not blame my knowledge and fluency of English for your lack of understanding.
You asked for a citation, I said I did not need a citation since the following is common knowledge AMONG MAGICIANS:
"Teaching a method behind an effect in a public, is what is labelled as exposure unless it is your own effect which you reserve the right to teach."
So I do not need a citation to be able to make the following statement which you asked a citation for:
"In fact, undoubtedly, some anti-exposure extremists would even label Wayne Houchin's brilliant show "Science of magic" as exposure."
So according to the common knowledge definition of the word "exposure" among magicians, Science of Magic is exposing illusions.
As for your "Brotherhood of magician" argument, that is a brotherhood you get into by merely "signing up on E or T11" and getting free tricks which is again exposure, just a bit inconvenient to laypeople.
Once again, I never said magic was common knowledge, I said the definition of exposure among magicians was common knowledge.
In fact, undoubtedly, some anti-exposure extrimists would even label Wayne Houchin's brilliant show "Science of magic" as exposure.
P.S. Now that we are moving in circles with these, can someone from the super secret brotherhood of magicians that can be accessed by entering your email address add a new point or stop maligning the names of two of the best performers of this generation who have elevated the name of the art on many platforms giving newcomers a chance to be on stage and on tv and open their gigs?
P.P.S. I do oppose exposure of commercial effects because that hurts the creator who is making money off it and his livelihood depends on it. But persecuting guys for doing a semi-exposed sponge ball routine is pointless. Sometimes you gotta show them how a french drop is done for them to appreciate your performance of Alchemy.
Final point has anyone ever done a trick and then heard "oh! i know how he did it! i saw it on...."?
Magicians are hilarious, always attempting to violently guard and debate over secrets behind a door. Unfortunately they forget that door is not locked and anyone can go to the door and turn the handle.
Also lets all chastize David Copperfeild For being the Founder of Magic is Medicine and all the SAM members who teach magic tricks like the crazy man's handcuffs to help ill people build finger strength. I make five thousand dollars off of that one trick, how dare they expose this for such a negligible cause. Burn them at the stake, god damn monsters!
No one is chastising them for teaching, key word there teaching, kids simple magic as a way to help build self confidence and as a rehab tool in a private setting. I have been a part of one of these groups. Who we chastise are those who publicly expose on youtube, an open public forum, the foundations of magic and commercial effects for no other reasons to be cool and get likes and subs.
There are magicians out there who will not share or release their methods to keep them out of the hands of those who might expose them. Then we have people like Teller who will openly expose magic on stage but then sue someone who sells the method to one of his effects. Why can't that person make money off of how that effect works since Penn and Teller make money on telling other how effects work?
If it were 1801, I could understand.
You have to realise that people who kicked P&T out of magic castle probably lived through that year XD.
Also there is someone on this forum who can tell you about getting booted from the castle for making exposure videos.
