The Wilcox-McCandlish law of online discourse evolution, developed by Bryce Wilcox and Stanton McCandlish on USENET, is
The chance of success of any attempt to change the topic or direction of a thread of discussion in a networked forum is directly proportional to the quality of the current content.

There are numerous corollaries:

McCandlish's first corollary to the Wilcox-McCandlish law:

The chance of any change to the topic or direction of a thread being a change for the better is inversely proportional to the quality of the content before the change.

The exception to McCandlish's first corollary:
When a thread reaches the flame-war stage, all changes in thread topic or direction will be changes for the worse.

McCandlish's second corollary to the Wilcox-McCandlish law:
Thread bandwidth consumption increases in inverse proportion to thread content quality.

Wilcox's corollary to the Wilcox-McCandlish law:
The more involved one is in a flame war, the less likely one is to recognize it as such.

McCandlish's third corollary to the Wilcox-McCandlish law:
Any attempt at recourse to formal logic or identification of classic fallacies will simply increase the irrationality of the discussion.

The Wilcox-McCandlish paradox:
Thread degeneration can (theoretically) be forestalled or even reversed by citation to the Wilcox-McCandlish Law.
