Lykken's First Law

The quality of one's intellectual productions is a function of the product of talent (e.g., intelligence) times mental energy. Although there are many and varied tests for assessing intelligence, psychologists have not as yet even attempted to construct a measure of individual differences in mental energy.

Lykken's Second Law

The mind consists of genetically-determined hardware and experientially-determined software. The hardware components are not constructed by genes working either individually or additively but, rather, by groups of genes working sequentially and configurally. Each human mating produces at least some gene configurations that are unique, having never occurred previously. This is why, among other things, human genius often occurs uniquely in an otherwise undistinguished family line.
