The experiment was bullshit and I'm tired of people bringing it up.
The problem with the methodology was that they used a mere 8 breeding pairs as a basis for the entire population and they were already from an relatively inbreed laboratory line. Hence the results are suspect to begin with.
But even if the experiment had been conducted differently it doesn't really fit with our society, people merely see what they want to see. I will posit some significant differences between the experimental environment and our own.
1) Significant areas of settlement are not over populated whereas in the experimental enclosure population density was relatively uniform.
2)There were no distinct breeding populations within the supra-population of the enclosure so far as I am aware.
3)"Boredom" isn't present in our society indeed the problems are likely a result of too much stimulation and the cheapness of pleasure.
The model isn't really applicable and a more accurate model can be created though the observation of the current situation as it develops.
Liberals aren’t breeding anymore and temperament and predilections to certain political positions are very much inheritable, the 2010 US survey, GSS, and Europoll 2011 both found that 93%+ of individuals had the same political and religious affiliation as their parents once they were older than 25. Indicating some form of heritable trait is being passed on.
You can see it in the birthrates by political affiliation and race within in the USA. White Democrats: 0.9, Jews: 0.8, blacks: 1.4, and spics: 1.6. White republicans are between 2.6 and 2.9 depending on whose numbers you use, with the highest being recorded in the General Social Survey which also has the largest sample set.
If the 2014 white conservative birthrates and those of the other demographic groups remained constant without additional input via immigration by 2050 only 20% of individuals in the US will be descended from habitual Democrat voters or self described liberals and only 7% will be black.
That is what the demoshits have feared for so long, that is why they want to import shitskins so desperately.

It goes beyond mere social incentives, the spics and niggers and libtard whites and mudslimes and kikes all don't breed when they have gibs. The bread and circuses are poisoned and only those who refuse to partake survive in the modern world. In the natural environment those who sought pleasure survived because natural selection had made it pleasurable to engage in adaptive behavior such as breeding and the harsh nature of pre-industrial environments meant that go get pleasure elsewhere one had to achieve material wealth. Now pleasure has been cheapened to such an extent that any scum sucker can get his fill. They have their Electric Jew, they have their vidya, their drugs, their consequence free sex, their food provided by welfare, ect. They don't need to engage in adaptive behavior anymore.
