Once again, in preparation for a post I compiled a few studies regarding a specific topic and figured I’d share them early. In addition, any studies you’d recommend I add would be greatly appreciated.
Here are all of the studies I could find on intelligence and income.
This is collected from scientific papers and analyses done by popular bloggers, hence some weird names in place of a typical last name for a source (such as Pumpkin Person)
Also, not all of these studies were done on individual IQ’s and incomes (some looked at regions, countries, etc.) so if they don’t I’ve left a note for the study at the bottom:
|Pumpkin Person (2016)||r=0.49|
|Rushton and Templer (2011)||r=0.54**|
|Lynn and Vanhanen (2006)||r=0.68***|
|Zax and Rees (2002)||B=0.06|
|Nyborg and Jensen (2001)||r=0.36|
|Irwing and Lynn (2006)||r=0.317(women)-0.368(men)|
|Fergusson et al. (2005)||B=1,595*****|
* = Two things to note on this study: 1) it was only done in Italy, 2) it was done on regional differences in IQ and their effect on average incomes. Hence this isn’t a traditional individual-based study, which is likely why the correlation is so high. It was worth including with a note, regardless.
** = This analysis was done on state IQ estimates and compared to average income within states.
*** = This analysis was done on national IQ estimates and national average income.
**** = This analysis was done on state IQ estimates and median family income. This likely leads to a higher correlation because not everyone in a family contributes equally to the family income. See Pumpkin Person (2016) which finds the correlation to family income was quite a bit larger than that for individual income.
***** = Gross income over a year
