James Flynn, famous for the Flynn effect (increase in both fluid and crystallized intelligence test scores measured in many parts of the world over the 20th century), believed that it might be less then 50% and wanted to do studies to prove this and even liberal universities wouldn't fund it. Hmmm. I wonder why a liberal university wouldn't want to prove IQ could be more environmental? Wouldn't that help their narrative? Well it's probably because regardless of their public stances that there are no races and IQ doesn't matter they privately KNOW IQ is genetic and ANY future research will just make that more and more obvious (and prove that they were dead wrong when they drove Rushton and Murray out of academia).
We welcome 100s of studies showing the flexibility of IQ (if they are well designed). The alt right isn't about science denial. It's the opposite of that. We are not trying to push IQ science into the public limelight because we think it shows whites are superior. We are pushing it into the limelight because we are forced to live a lie everyday from both liberals and conservatives that it doesn't exist at all and that it doesn't have any bearing on how we plan society and doll out welfare and managed immigration. This is a HUGE lie. This is the emperor with no clothes. The bell curve effect of IQ, even if it's flexible, shows there are significant differences between races especially as you get out to the edges and these desperately need to be taken into account when trying to create and perpetuate a prosperous society.

In fact studies showing it has flexibility would get you kicked out of most SJW circles because SJW's deny IQ in its entirety. How can you show in a study that it's flexible if there's no such thing as IQ in the first place?

The environmental factor of IQ also shows how important schooling is and how important it is for us to resegregate schools. A 73 IQ sub saharan african with the right schooling, nutrition and motivation might be able to able to crack the bare minimum of military acceptance: 83. But that child will hurt jewish, white and asian kids with 100 plus IQ.
Even accounting for flexibility of IQ, desegregation and forced diversity is a losing game for everyone INCLUDING sub saharans who would be miserable in homogenous white or jewish school with kids who are reading in kindergarten. (which is why jews are frequently putting their kids in private school). In fact jewish and white politicians both will put their kids in prestigious high quality private schools with similar IQ cohorts while voting for shitty desegregated public schools for the rest of us. It's a goddamn fraud.

Unfortunately many whites don't have the finances to put their kids into homogenous private school. You are only proving to us that importing all these low IQ blacks and hispanics is part of a long term plan to reduce white IQ (because whites are the most effected).
