But if they didn't even come close to measuring it then there would be no correlation ? It's not like these tests are applied retroactively to explain past performances - they offer actual predictive value. Selection bias can account for some of it but there are ways to test if this and from what I've seen it still holds up.
- runarberg 5y agoI’m not disputing that these tests measure something, they obviously do. However what they are measuring is not what most people consider a satisfactory definition of intelligence. In fact most psychometricians simply give up and define intelligence based on what these tests measure (i.e. operation definition). Without justification that is very poor science.
- plorkyeran 5y agoSAT scores would be positively correlated with success even if they were entirely random as long as universities continued to use them as a factor in admissions. It's sort of a corollary of Goodhart's law that it is difficult to assess the quality of a measure while it is being used as a target.
