I literally already told you:
...
It is entirely possible for the IQ coefficient of life SES status to be higher in the US than in the EU, and for overall social class mobility to be better in the EU.
These are in no way contradictory.
If 10 out of 100 people of say >115 IQ in the US do better in life than their parents...
But 30 out of 100 people of >105 IQ in the EU do better in life than their parents...
Then the EU has better overall social class mobility, and IQ is less strongly correlated with SES improvement, than in the US.
This is literally what a statistics teacher would call a 'trivial' example, because of how basic and obvious it is.
...
Measuring the factors that go into SES shifting is completely different from measuring how many people SES shift.
How many people do a thing?
...is not the same question as...
What kind of people do a thing?
...
Honestly, if you don't understand that this is possible, that this is an entirely non contradictory scenario...
Then its pretty clear you do not have any sufficient training in statistics, that you are not actually capable of having a meaningfully informed opinion on any of this.
It would take me too long to teach you, and I am used to being paid for my time when it comes to using my Econ degree with a specialization in Econometrics.
Go take a Kahn Academy course or sign up at your local community college or something.
The studies you cite in your second comment don't support this. They show less class mobility in both directions.
My... second comment?
What does that mean?
My second reply to you?
My second reply in this whole thread?
If you're talking about the thing I most recently linked from Cambridge...
... 2 of 3 of those links were not even academic studies, just amalgamated data sets.
...
Again, you're not getting the basic concept.
How many people are upwardly or downwardly mobile... is not the same thing as which kind of people are downward or upwardly mobile, what factors play into that to what degree.
The Cambridge study mentions the former and proposes an explanation for this.
The 2016 study looks at the latter and attempts to explain that.
I am saying that, of that lower upward and downward mobility in the US from the Cambridge study... the only people who can move up are exceptionally smart, and the only people that move down are exceptionally dumb.
Whereas in the EU, you do not need to be as extremely smart or dumb to move up or down socially, thus it occurs more often.
...
I am sorry, but again, you clearly do not understand statistics to have a meaningful discussion on this, please, I am not trying to merely insult you, please actually learn statistics so that you can actually have a useful opinion on this topic that you clearly care about.
