I know that this question has only a proper approach: from neurosciences. Psychology will always have a problematic approach to this question due to his 'only empirical' nature. I don`t even consider phenomenology nor psychoanalysis if we are regarding the question scientifically.

But, I think 'abstract' thinking is not a specific mental process per se.

I explain myself: I believe this process is the sum of other two more 'mundane' processes: memory and fantasy.

I mean by fantasy the capacity to take some elements from memory...

Natural selection works through removing traits which prevent the offspring from successively reproducing, if the trait doesn't prevent successful reproduction there will be no reason why it won't be passed onto the next generation.

Everything I see written about the subject of quarternions says that for

Q = A + Bi + Cj + Dk

has the condition that

i^2 = j^2 = k^2 = ijk = -1

How can this be true that ijk = -1?

If i = sqrt (-1) and j = sqrt (-1) and k = sqrt (-1)

Then

Ijk = sqrt (-1)*sqrt (-1)*sqrt (-1)

That does not equal -1.

Is this 19th century trolling?
>>
>>8499029

Don't bother learning quaternions, they are useless. Litterally. Absolute garbages. The most useless field in maths.
>>
>If i = sqrt (-1) and j = sqrt (-1) and k = sqrt (-1)

Thats your problem right there. The condition i^2 = j^2 = k^2 = ijk = -1 is strong, thats how that quarternion units are defined, similar to how the i is defined with i^2 = -1, or some equivalent form, with the complex numbers.

Hello /sci/.

I'm making software to analyze boards and threads on 4chan.
How do I measure intelligence of a board? I was thinking of something including image ratio, length of posts and sentimental objectivity.
Also, what other metrics should I consider?
>>
>>8498102
The only thing considered a measure for intelligence is the intelligence quotient, there are tests for that. If you want to determine the intelligence of a poster by their posts, you need labelled data to train a regressor. You don't have that. Everything else is just guesswork.

Anyway, if you want to look at interesting quantities by themselves you may look at features such as:
>Number of different words per thread
>Length of posts

>>
>>8498115
Yeah, I already got half of those you said.
A really cool one would be something along the lines of keywords, words that are not on the list of 10,000 of the most popular English ones, but the most popular on the board. I wonder what the outcome would be for different boards. I also want to include plotting graphs. And I don't want to do anything with machine learning just yet.

11 KB,
consider the following

is it possible that some tens of thousands of years ago, some of our ancestors who left africa for the middle east and later europe were on average more intelligent than those that stayed behind because realising that it was a good idea to leave africa could not be done without a certain level of intelligence? and as a result of that, is it possible that "native" africans are more likely to be be of lower intelligence?
>>
>>8497478
>>8497478
Please don't bring ancestral dna circle jerking to this board; we had threads that got deleted and people banned left and right from /pol/ and /int/. Let's not shit this board up with these kinds of matters.

To answer your question, there's been studies from the other side that Europeans didn't come from Africa but rather everyone started in a different continent; rather than the WE WUZ AFRIKANZ meme perpetuated by the lefty scientists.

Your thesis is possible. It's also possible that certain parts of Africa evolved and everyone else just were degenerates or became degenerates due to degradation of culture and life.

It's also possible you, the OP, may be an artificial construct and that I'm just a dog slobbering all over his computer smashing his head to make this coherent and educated post. Who the fuck knows, anything is possible at this point.

I think the real question is not to ask whether Africa has idiots or not but rather how can we help terraform the continent. The biggest issue there is the lack of irrigatable crops and almost no biodiversity in the desert areas in middle of the continent
