As a public service to those members of the forum who are unaware of the possibility of genetic enhancement of human intelligence to 1500 IQ (or greater) please be so advised.
Clearly this will create a massive discontinuity in human history: A Genetic Singularity Event.
Prepare ... Now.
Everything that is currently understood as a guide to human behavior and human society will soon
no longer be valid.
This topic has been discussed mostly by me at length on the Genetic Singularity thread, though I am aware that many would not have been following such posts. I thought it wise due to the critically important nature of this topic to make it a thread unto itself. This could be for those who only manage to read the headlines before continuing with their other activities.
In this instance the headline might read:
Scientists provide a mathematical proof that extremely large increases in intelligence are possible, and given the competitive nature of the human species likely to occur over the short to medium term.
Not exactly a snappy headline, though it does at least express the main idea.
For those interested, here is some of the background. Genetic studies over the last 10-20 years have conclusively established that intelligence and many other traits and illnesses are highly polygenic.
Yet, the largest effect IQ variant that was found with sample sizes into the thousands explained 0.01% of the
variance in IQ. An enormously small effect size. Many in the research community had almost given
up on genetics having any role to engineer a better more intelligent future of humanity.
However, it appears that one largely overlooked idea from this research was that with so many of these small effect size variants there would be an enormous opportunity to radically enhance human intelligence.
To clarify this consider flipping 1 coin. Half the people would wind up with a head and half a tail.
If intelligence were like that then we would have a very divided- bipolar- community.
We don't.
Intelligence is obviously not determined in such a way.
Now what happens with 2 coins? We would wind up with 3 genotype classes and all of the classes
have a substantial probability of occurring. Life isn't like that either.
With ten coin tosses we no longer expect to see a maximal phenotype frequently occurring.
This is perhaps how researchers might have thought genetics worked with intelligence.
There would be a fairly limited number of variants and the extreme phenotypic limit would
be not much higher than what could be observed in the community. Most of the kids can fit
into a normal school context and the community would be largely be able to have a stablish
psychometric veneer.
With 10,000 coins it becomes essentially impossible to expect that anyone would
hit 10,000 heads. We still have an IQ distribution that allows for most kids to function in a generic academic
environment, though now the observed IQ phenotype is higher with a large enough population.
The phenotypic extreme is never observed and it is far beyond anything that
could be imagined. Intelligence and many other traits have such a genetic architecture.
The sociopolitical implications are overwhelmingly profound.
I can post further details of this later if there is an interest, though briefly it is now possible to
find all the variants involved in human intelligence. The upper range of human IQ is thought
to be roughly 1500 (give or take). Clearly we have now reached a point that I am referring to as
the Genetic Singularity. Other traits such as schizophrenia, anxiety and many many others would
follow a similar logic. The potential to radically reimagine humanness has now arrived.
