My independent research on psychometrics/statistics

• Regression to the Mean Effect in the Genetic Transmission of Intelligence
• Estimating verbal IQ of math olympiad top placers
• How high is the parental IQ of most geniuses?
• Deriving general IQ SD given math SD and verbal SD
• Math-verbal correlation conditioned on general IQ
• Calculation of parent-child/sibling IQ correlation
• Predicting IOI results from contestant photos

The above research/writings were indirectly inspired by the book The Son Also Rises  by Gregory Clark, which did a statistical study of social mobility based on longitudinal (over many centuries) surname records.
