I'm going to propose an hypothesis here
The more noise there is, the more sincerity stands out.
Once the noise reaches saturation, that's when sincerity stands out the most, making all the noise empty background with no obfuscation effect, basically making noise itself ineffective.
A saturation of noise defeats the purpose of noise.
This is similar to an other effect in the economic field.
The more power and wealth concentrates into few, the more all the rest left out have a common ground to band together against the few, leading to the collapse of the few.
This other idea could be names instead "the monopolism collapse principle"
Noise can be understood to be any of: lies, distractions, subversions, distortions, empty talk, all purposefully done to waste time and to drive away from truth.
Often truth is attacked because truth is what makes a crime to be visible and recognizeable to anyone, so the criminals are interested in keeping truth away from public attention.
Truth standing out the more lies and corruption is widespread is why evil always loses.
Or why it's said the father of lies is a loser.
Truth doesn't fear to be surrounded by lies, because truth includes into it everything which is exact, including how lies are fake and gay. So the more lies are created to oppose truth, the more truth grows to include more anti-falsity as a result of having made all lies be seen for what they really are.
Lies and liars are pathetic on a fundamental level.
Either they hide in fear of getting found out and punished for their falsity, while Truth dominates, or they lead to their own destruction if they try to grow too big. Either way, falsity always loses.
Truth always wins.
