It is theorized that if an inverse correlation of IQ with fertility rate were stronger than the correlation of survival rate, and if heritable factors involved in IQ were consistently expressed in populations with different fertility rates, and if this continued over a significant number of generations, it could lead to a decrease in population IQ scores.

The Flynn effect demonstrates an increase in phenotypic IQ scores over time, but confounding environmental factors during the same period of time preclude any conclusion concerning underlying change in genotypic IQ.

We hypothesize that there will be a correlation between the amount of tattoos one has and their participation in risky activities.These men, taken as a whole, had few children, implying a correlation. A decline in average psychometric intelligence of only a few points will mean a much smaller population of gifted individuals.Nobel Prize–winning physicist William Shockley controversially argued from the mid-1960s through the 1980s that "the future of the population was threatened because people with low IQs had more children than those with high IQs." In 1963, Weyl and Possony asserted that comparatively small differences in average intelligence can become very large differences in the very high I. More rigorous studies carried out on Americans alive after the Second World War returned different results suggesting a slight positive correlation with respect to intelligence.We would launch a mobile version for Android, i Phone and Symbian(If Possible).There is a flood of apps and websites that help you find a date.It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.To restore access and understand how to better interact with our site to avoid this in the future, please have your system administrator contact [email protected]
