It is Gauss' Law

How are we supposed to interpet the Flynn effect?

When people say that IQ is largely genetic, they mean that a large fraction of the variance in IQ can be explained by genetic factors. If you think about it, that doesn't contradict at all the idea that IQ could drift massively over time -- because the explained variance is only with reference to a particular population in one particular snapshot of time.

sin(x)/x is undefined at x = 0, but the limit of it as x approaches 0 is 1.

When people talk about different races, do you they mean different ethnicities, or different species?
5 posts and 1 images submitted.
>>
It depends on how you define species, and the scientific community is inconsistent on this.

For instance, they call the Coyote and the Wolf different species even though they can breed together.
>>
All taxonomic groups are essentially arbitrary. None are valid or invalid, they are basically just ways of organising/grouping multiple individuals to make patterns more easily understood.

Hey /sci,

What is the optimal format for a review of an article? I'm used to using the basic structure of:

Intro
Methodology
Results
Discussion
Conclusion

but that doesn't obviously doesn't fit here.

I realize this is almost homework tier but I just can't seem to figure this out and it's triggering my autism hard. Any help is appreciated.

>but that doesn't obviously doesn't fit here.
I cannot parse that one, sorry.

Anyways, some discussion of previous work is usually in order, especially if you intend to make comparative analysis.
>>
>>9170703
>a review of an article
What do you mean by this exactly?

- A review, as in, an independent assessment that is meant to advise an editor of the quality of a submitted manuscript?
- An article that synthesizes a body of literature into a coherent framework?
- A commentary on a single published article?

The structure differs for all of these.

How high does one's IQ need to be to avoid falling for a placebo effect?

Brainlets: Placebo just works
Pseudo-intellectuals: Try to resist placebo to try to prove how enlightened they are
High IQ phenotype: Willingly perform the art of doublethink themselves into being cured via the placebo effect without even needing to eat a pill, just through raw force of will
>>
Don't think IQ would help much.
Maybe having extensive knowledge of drugs and medicine would help so you could tell the difference between a sugar pill and actual medicine.

In terms of earnings and career prospects medicine trumps almost every other scientific field. However if you are not biochemically, physiologically inclined the next best option is petroleum engineering.

The average vagina is about 2 to 3 inches deep when unaroused. When aroused, it's about 4 to 5 inches deep. Obviously most women can insert penises of a longer length all the way in because the vagina can stretch out.

Have there been any reliable studies showing how deep the average aroused vagina can get stretched? What about in terms of width?

so how many sexual partners do you need on average until you find one that can fully fit lets say a 7,5" penis?

I'd volunteer as male test subject if you are planning a study

I have heard about homeopathy recently and how it >supposedly< does wonders for people who have bad health.
For example, you have problems with digestive system, immunity, neurological problems, allergies, mental problems all at the same time.
You see one type of doctor for one thing, he gives you one drug. But this drug fucks up another thing.
So then you visit another doctor, and he gives you another drug and this drug messes up something else.
So the circle closes, and you are left with more ilnesses than you had to begin with.
Now, supposedly homeopathy works like that: you visit a homeopathy doctor, you give him all your problems and he alone cures all of them.

But on the other hand I have read that the drugs given by homeopaths are basically not doing anything and it's just a placebo effect.

Have anyone here ever tried homeopathy? Who should I believe? Is homeopathy just a meme?

https://en.wikipedia.org/wiki/Homeopathy
>Homeopathic preparations are not effective for treating any condition;[2][3][4][5] large-scale studies have found homeopathy to be no more effective than a placebo, indicating that any positive effects that follow treatment are only due to the placebo effect, normal recovery from illness, or regression toward the mean.[6][7][8]

I was actually told by my psychologist to visit a homeopath. So one pseudoscientist recommended another pseudoscientist?

>dude how about we dilute the active substance to the point where you can't even detect it?
