Post about your politics regarding science. I'll start with this topic: What are your thoughts on gene editing? What are your thoughts on big pharma and government collecting and selling your genetic data? Etc.

I support all forms of genetic research. In regards to government selling genetic data, I am a believer that government does not sell anything ever, a true government knows this data can be obtained anyway so they will seek to collaborate in order to gather info as to who is interested in this, why and what are their potential capabilities! I believe in deep government censorship because I know what human being are capable of! I also believe in balanced progress which is difficult to achieve in general, so shifting judgment on anyone and thinking that any side is stagnating progress, weather government or individual public is not very reasonable given both can contribute on that aspect!

Depends where you're working. Without a strong research background in Statistics, they're glorified plug-and-chuggers who can get numbers out of a black box, but don't really understand how it works and are incapable of doing anything innovative. For your average company, this is really all they need, but for big N you're not really competing with them at all, they explicitly want a research graduate degree in math/phys/compsci.

>“IQ” is a stale test meant to measure mental capacity but in fact mostly measures extreme unintelligence (learning difficulties), as well as, to a lesser extent (with a lot of noise), a form of intelligence, stripped of 2nd order effects—how good someone is at taking some type of exams designed by unsophisticated nerds.

So lets ignore all of that for now, and give the benefit of the doubt that we can actually calculate the abstract notion of "IQ". To this point "IQ" is a purely abstract number.

Now we need to do correlations into real world data to figure out if it actually means anything.

So for nearly the past century, Psychology grad students have gone out and collected any dataset they can get their hands on and did linear regressions against IQ. Things like Educational achievement, Income levels etc.

Off the bat we have an obvious issue here. Pretty much ever IQ correlation study ever uses linear models, with the implicit assumption that IQ has a linear relationship to some outcome. Unfounded. We are completely blind to any non-linear affects.

Now you factor in that the people doing these correlation studies can just p hack until they get something worthy of a publishable paper, and we then realize that we have an entire body of literature that is pseudoscience non-sense.

Ok so maybe lets give benefit of the doubt again, and assume the studies were done properly. We now have to consider that these result only hold for populations of subjects, and we can't really use them to make predictions about individuals. Why? Because IQ score itself is an extremely noisey estimate, sample size of 1. Really we should have collected the results of multiple IQ tests for each individual and used them to compute an IQ estimate. But there is a huge problem here. IQ tests, and all of the scoring and normalization used have an implicit assumption in them. That assumption is that this is the first time you have ever taken an IQ test. So we can't administer multiple tests even if we wanted to, because every additional IQ test is invalid according to the assumptions we made at the very start.

Theres plenty of more bullshit I can point out, like the inherent cultural biases in IQ tests, or the fact that IQ scores are age normalized but I think I got my point across.

>> No.10571854

>>10571842
>To say that IQ doesn't exist because we now have better methods is just dishonest.

No one is saying "IQ doesn't exist". Neither I or Taleb. The point is IQ tests measure IQ and IQ only, which is an abstract quantity developed by wonky psychology models from the 1930s.

Strictly speaking we cannot say that IQ == Intelligence. This is basically the bulk of Talebs point if you actually cared to read it. Basically once you pass 100 IQ, all of the correlations against IQ start to rapidly fall apart and become statistical noise.

I will grant, and Taleb makes this point as well, that IQ actually does seem to be a good predict of stupidity. IQ < 100 actually does hold up statistically pretty well.

>> No.10571860

>>10571846

Also as far as success goes, the role of personality should be taken into account. If you have someone of high intelligence (IQ) but they are low in conscientiousness odds are they will not be as successful as someone of average/slightly above average intelligence and highly conscientious and creative. I highly doubt everyone in MENSA has patents and millions in the bank.

Do you believe numbers have "magical" properties?
Like 5 for example. It was very important for Pythagoras, and the Chinese. Also the complete 5 graph is the well known pentagram, it was very important throughout ancient human civilizations(and later on associated with Satanism). And it also looks like a human, with its feet and its hands and its head. Also we humans have 5 fingers. Is 5 the human number?
Some other numbers like 7, which are considered lucky and by many divine. (if you look at k7 graph it looks like an angel, because its like a human but it also has wings).
Or 6, which is strongly connected to the material plane(so people sometimes associate it with Satanism) and the k6 graph is also the basis of Davids Star (maybe this is why Jews have a strong affinity to money)...
Is there more to numbers or I am just being schizo?

It's not that rare. If he is experiencing jumbled thoughts, blank mind, and loss of ordinary conscious thought stream ... but he is still able to talk and walk around.. schizoaffective is likely.

The epidemiology of schizoaffective disorders suggests high incidence of under-diagnosis and mis-diagnosis.

If OP is around ages 16-25, it's worth considering.
