By Richard Lynn

This ebook demanding situations social scientists to re-examine the theoretical foundations of the research of social phenomena. earlier social scientists have assumed that various environmental components clarify social phenomena and that there can't be any universal explanatory issue in the back of a variety of social phenomena. even though, the empirical facts offered during this publication and masking approximately 2 hundred international locations exhibits that many different types of human stipulations count considerably on changes in normal intelligence of countries (national IQs).

Differences in intelligence aid to provide an explanation for every kind of phenotypic social phenomena in addition to the patience of social inequalities on this planet. Environmental components affecting such phenomena range from case to case, yet intelligence reflecting the developed human variety continues to be a similar explanatory issue throughout all phenotypic social phenomena. which means it offers a unifying theoretical build for the social sciences. regrettably social scientists haven't but discovered that almost all difficulties explored in social sciences are phenotypic phenomena looking on either genotypic and environmental components and that intelligence is a strong genotypic universal explanatory factor.

The arguments and hypotheses offered during this e-book are proven and supported by way of vast empirical facts. eventually empirical proof will make a decision the future of conflicting theoretical arguments.

Contrary to these assertions, we have gone to considerable trouble to demonstarate that our national IQs are valid. The validity of an intelligence test is the extent to which it measures what it purports to measure and is established by showing that it is highly correlated with other measures of cognitive ability. Foremost among these is educational attainment.
