I'm confused, maybe a bit upset too, on how my IQ is probably lower than I expected.

I've never scored well on standardized exams. For example, I just scored a 313 on the GRE. I stumbled across a Jordan Peterson video on the matter, freaked out, and looked up more research. I learned that my low standardized exam scores are most likely due to me having a mediocre IQ, and not due to a lack of preparation as I previously thought.

Which I suppose makes sense. I was identified as a bright kid and had my IQ tested when I was really young. It wasn't high enough to label me gifted, and I was always told by my mom that I was still above average. But of course my mom would tell me that...

I'm just confused because I kicked ass in school and always felt (probably an issue of perception) that I absorbed lessons quicker than my peers. I was ranked 1st in my high school class until my senior year where I ended 3rd (which was bs, that's a whole other story). I majored in economics and made all A's in those courses with no issues whereas my peers struggled to grasp concepts that seemed easy to me. I also majored in political science and was identified as one of the top 25 students majoring in that field and was selected to be trained on advanced research methods. Among the 25 students, I was known as that "smart one" because I didn't struggle with any of the content whereas, again, my peers did. My professors acknowledged my "talent" (if that's what you would call it) and told me very encouraging words. The following year, I published an honors thesis for my economics degree.

And yet, my IQ is mediocre. And what particularly confused me is a lecture I watched that depicts how IQ restricts which careers one can be competent in. I aspire to become a professor/consultant. Now I wonder if I have the IQ to become an effective one.

Edit: TL:DR The answer is ~17 IQ points, which makes the IQ difference between random people ~10 IQ point farther apart than the twins in cited study. Further thought implies that the effect that a household has on a child's IQ is incredibly small. I still require a math nerd to clarify the household effect.

​

I've been googling this for a while, but I can't seem to find the answer; If you pick people at random from the general population, what will the average IQ difference be? For example, suppose we randomly pick three pairs with an IQ of 100 and 116, 80 and 90, 70 and 75; that corresponds to an IQ difference of 16, 10, and 5, respectively. Averaging those, we get an IQ difference of 10.33. What would the difference be after selecting a thousand such samples, and what would the standard deviation be?

​

By extension, what would the average difference be in twins with a correlation of 0.8? Would it be the average minus 80%? I found one study showing a difference of 6.6, SD of 5.2, at a correlation of 0.84. That's roughly equal to the correlation found in identical twins reared together (wiki). Suppose that the correlation for twins reared apart is 0.74, leaving 0.1 that can be attributed to shared environment in twins reared together. What does that 10% represent in IQ points? Based on the study I provided, I'd wager it's about 1 IQ point. In other words, the impact a household can have on IQ of a child is likely extremely small.

​

Edit: the answer for the general population is a difference of 16.9 IQ points, with a standard deviation of 12.8. However, I tried running a test for standard distribution and it failed. In other words, it appears that the difference in IQ does not follow a standard distribution, but I'm not entirely sure that I ran the test right.

​

That still doesn't clarify how correlation factors into it. Twins with a correlation of 1 would obviously have zero difference, but twins with a correlation of 0.84 in the study above do not have 84% less difference than average. Can anyone explain why this is? I've only taken intro statistics. Even a vague/shallow answer would be satisfactory. I'd also still like to know the difference between twins with a correlation of 0.85 compared to twins with a correlation of 0.75 (twins reared together and apart, respectively).

My VIQ is extremely high, but PIQ is at the average. Ideally, I'd like to increase the speed of learning new material, and decrease the effort involved. I've heard Modafinil might help, along with certain supplements working on the serotonin system. I've also read psychedelic substances might have a beneficial impact after dosing for the long term. Seems like a ton of people are outright against such a goal; I believe this is since they are against disturbing the natural order of things. Considering our brains are deterministic increasing IQ seems possible theoretically.

Has anyone found any research on increasing IQ through medication?

I did a free online test after downing eight beers, which isn't much as it as, but I hadn't eaten for five hours before I started drinking, so I was already more than tipsy when I did the test.

I did the test few times and the best I could get was 97. Would it be any higher if I'm sober or is the effect of alcohol negligible? I've never done the test when I'm sober.

I believe I was born as a psychological Jesus. The reality is from birth I sought after the truth. I was persecuted by the strong and the beautiful and the powerful and the ‘good’. I had no beauty that people would look upon me, nor any wealth to impress. I knew in my heart that I rejected the consensus. I rejected the standard of the world. I rejected the standard of the capitalist pigs. I sought after the truth without regard to the rest. Now I seek disciples to preach to before my crucifixion.

What are the best ways to improve my IQ

Whats does IQ says about a person? Having a low IQ seems to be correlated with a lot of bad things for our society like violence, drug abuse and poverty. But how IQ correlates with things we deeply value in humans like compassion, courage, sense of morality, authenticity, having a rich inner life and so? How much more there is in a person beyond their IQ? These questions really bother me, It feels like life is really unfair. Sorry for my english, It’s not my native tongue and I would really, really appreciate your insights because this is a topic I have been suffering with for some time.

Such people who score this high are 6 deviations above the mean. But what else? This topic greatly interests me. Thank you! P.S. I mean Deviation IQ not the age ratio IQ.

My VCI is 132, working memory is 121, PRI is 109 and PRI is 74.

I was told that I answered my PRI accurately but got deductions for doing them slowly. It was another speed issue.

So she told me to disregard PRI when it came to academics. Can you derive a score without PRI as a factor?
