Shank's Law is internet shorthand for a common response to the logical fallacy of "Argument from authority". It states: " The imaginative powers of the human mind have yet to rise to the challenge of concocting a conspiracy theory so batshit insane that one cannot find at least one Ph.D holding scientist to support it."
Proponents of conspiracy theories often attempt to lend their swivel-eyed nonsense credibility by citing the "findings" of one or more Ph.D professors. However, they fail to appreciate that the fact that a person holds a Ph.D doesn't necessarily mean they aren't crazy.
"Weasel semen is a proven cure for AIDS, especially when gargled."
"Bullshit!"
"You think so? Well here's a study by Professor Hodor of BumblefuckUniversity that proves it!"
"Shank's Law, bro. Shank's law."
The hippy chick that never shaves or grooms herself has the shaolin shackles and now needs a pair of scissors to free herpubic hair from the shorts she is wearing.
New chains means that you changed as a person , same shackles means that you still have (problems , depression ect) and that nearly nothing changed , you still feel as you did before the "new chains".
