Even for those of IQ 160 there is a huge difference between interacting with people whose average IQ is 130, and interacting with the general population.
This does not mean they will experience group bonding with those people.
Further, supposing IQ 160 is one-in-X in the world, it's one-in-X/10, or even X/50, in academia. Shifting the average has all kinds of effects on thin tails.
Okay, but you've got to consider that the students are broken up into different classes and the classes only contain something like 30 students each, depending, and they're broken up into levels (that correspond more or less to how many years they've spent in college). So if a rare person is 1 in 1000 in the wild, and they're 1 in 100 in a school, and a school has 10,000 students...
10,000 \ 4 levels = 2,500 possible students who might get classes at your level (25 people like you)
The 25 people like you will be divided between 83 different classes if the class size is 30 each.
So you've got about a 30% chance that there's somebody like you is in a given class. Now, since there are 28 other students in each class (aside from you and them), what's the chance you'll actually identify each other out of the crowd? After that, what's the chance you'll have anything in common? Maybe you won't like their personality. Maybe they're shy and never say anything. Maybe you sit on opposite ends of the room and never talk. There are a lot of factors influencing whether you might meet someone and whether you figure out if they're compatible.
If you are 1 in 100 and take 6 classes per semester, you may have an opportunity to meet 4 people like yourself in class each year. An opportunity to meet a total of 16 people like you over the course of your four year college career would actually be pretty crappy odds, especially considering all of the other factors.
Ok; now do the same calculation for the world outside academia, making similar assumptions - no going up to every random person on the street and asking what their IQ is, if you please. You can't do any better than maximising your odds; showing that the odds are still bad is unpersuasive, you have to show that they are the same as, or worse than, the alternative course of action.
My name is Brent, and I'm probably insane.
I can perform various experimental tests to verify that I do not perform primate pack-bonding rituals correctly, which is about half of what we mean by "insane". This concerns me simply from a utilitarian perspective (separation from pack makes ego-depletion problems harder; it makes resources harder to come by; and it simply sucks to experience "from the inside"), but these are not the things that concern me most.
The thing that concerns me most is this:
What if the very tools that I use to make decisions are flawed?
I stumbled upon Bayesian techniques as a young child; I was lucky enough to have the opportunity to perform a lot of self-guided artificial intelligence "research" in Junior High and High School, due to growing up in a time and place when computers were utterly mysterious, so no one could really tell me what I was "supposed" to be doing with them - so I started making simple video games, had no opponents to play them against due to the aforementioned failures to correctly perform pack-bonding rituals, decided to create my own, became dissatisfied with the quality of my opponents, and suddenly found myself chewing on Hopfstaedter and Wiener and Minsky.
I'm filling in that bit of detail to explain that I have been attempting to operate as a rational intelligence for quite some time, so I believe that I've become very familiar with the kinds of "bugs" that I will tend to exhibit.
I've spent a very long time attempting to correct for my cognitive biases, edit out tendencies to seek comfortable-but-misleading inputs, and otherwise "force" myself to be rational, and often, the result is that my "will" will crack under the strain. My entire utility-table will suddenly flip on its head, and attempt to maximize my own self-destruction rather than allow me to continue to torture it with endlessly recursive, unsolvable problems that all tend to boil down to "you do not have sufficient social power, and humans are savage and cruel no matter how much you care about them."
Most of my energy is spent attempting to maintain positive, rational, long-term goals in the face of some kind of regedit-hack of my utility table itself, coming from somewhere in my subconscious that I can't seem to gain write-access to.
Clearly, the transhumanist solution would be to identify the underlying physical storage where the bug is occurring, and replace it with a less-malfunctioning piece of hardware.
Hopefully someday someone with more self-control, financial resources, and social resources than I will invent a method to do that, and I can get enough of a partial personectomy to create something viable with the remaining subroutines.
In the meantime, what is someone who wishes to be rational supposed to do, when the underlying hardware simply won't cooperate?
