No causation required.
- shawndrost 17y agoIndividual effort is controlled for in the study discussed: "each extra required maths course raised the annual income of black males by 15%". Of course, this study still doesn't make a strong case for causation -- the number of required math courses in a school is likely correlated with school quality, which is likely correlated with other socioeconomic factors.
- jey 17y agoHuh? How do you infer that individual effort was controlled for by quoting "each extra required maths course raised the annual income of black males by 15%"?
- shawndrost 17y ago"each extra -required- maths course" -- as in required by the school. This is also made clear in the linked paper: http://www.columbia.edu/~jg2394/papers/jobmarket.pdf http://www.columbia.edu/~jg2394/papers/jobmarket.pdf
- lutorm 17y agoYeah, it's hard to figure out from that article how the study was done. Unless it's a true randomized study where people were randomly assigned to take either more or less math, it's hard to know how much of that is self selection.
