Small-Scale Question Sunday for January 22, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Thank you! I am very happy to finally see someone earnestly attempting to refute HBD arguments. For completeness' sake, here is an archive of the blog post, the source article and the presentation Chisala got his numbers from.

I remain unconvinced. There is no indication that the Somali sample is in any way representative of the source population. Here is Chisala's argument:

Their performance above American blacks (labeled as “English-speaking” blacks) defies the common sociologist explanation that higher achieving black immigrants are simply the most driven members of their source populations (some were just in refugee camps), and it equally defies the modern hereditarian argument that they are just the most self-selected in intelligence relative to their source populations, unless we now start extending this cognitive self-selectivity and “assortative mating” quality to people who run to United Nations refugee camps for protection. (It is not necessarily all who were from these camps, but that doesn’t matter since even those who were from there are performing above native black Americans).

Chisala seems to assume that most of the Somali sample comes from refugee camps. But the source article only mentions that "[The Somali children's] families came to the U.S. to escape their war-torn country, many by way of refugee camps.". Chisala puts this aside by saying that "It is not necessarily all who were from these camps, but that doesn’t matter since even those who were from there are performing above native black Americans". But I didn't get that from a cursory glance of the data, which only seems to report aggregate data. Even so, there are a whole host of different selection effects with those coming from refugee camps. As one commenter puts it:

In a country like Somalia, getting into a refugee camp may be more desirable than not being in one. And from there to be selected for relocation to America may also be more desirable than not.

As with most desirable things in life, those with a higher IQ or socioeconomic status may be better at working the system to their benefit to get them.

Chisala did, as far as I can see, not respond to this concern.

I have not yet looked at the UK data Chisala mentions.
