Scientists have painted bird chest marks darker using felt markers. They've noticed that the simple cosmetic change caused the bird itself AND those around it to conform to the new artificial standard, as if the felt marked bird IS in fact the dominant male.
So, if we look at today's society, it's full of birds wearing fake markers.
We've completely hijacked the signaling system such that Our Appearance and Cultural norms are Entirely-Synthetic, and NO LONGER reflect true-biomarkers of health / genetic truism.
For example, Hypothetically, a Human female who is genetically Buxom, produced more and/or higher quality milk, leads to more rapid/ higher development of early brain function/growth rates in babies fed by her. THIS FEMALE would be genetically selected for.
But, now when you've inserted Silicone Implants into the genetic marketplace, the Males are entranced by genetically inferior females who produce mentally less developed babies.
So, this process leads to the idiocracy situation, where Vanity driven aesthetics REPLACE genetic sexual selection.
There are numerous second order effects. For example, Say the wife is a 5, you would only mate n(5) so often, producing so many children during one's bout of monogamy. That rate is natural, representative of the genetic value of that relationship.
Now, the Wife gets silicone implants, and the male decides, n(7), suddenly the lifelong production of children increases at an UNNATURAL rate, which does NOT reflect the genetic value of that relationship.
Society, then enters dis-regulation, over-producing uncharacteristic/ unnecessary member traits. This is ROT, This is Behavioral Sink.
Just like Calhoun's mice which all died in the utopia they've been given.
