Early interests: Perception, sexual habits.
Principal researcher in a questionnaire-based investigation of the sexual habits of 10,000 randomly selected Norwegians 18-60 yrs old (response rate 63%). The study was done in 1987-1988 at the Norwegian Institute of Public Health.
A main research interest the last 25-30 yrs has been intelligence. Empirical studies of the relative impact of heredity and environmental factors in the variation and covariation performed on twins has been done together with other reearchers. The last years, and again together with other researchers, I have studied increasing IQ means across generations (the Flynn effect), that have been observed in many countries.
Access to the registers of the Norwegian Conscript Service, comprising intelligence-test data on close to a million men. Additional data from Statistics Norway enable the study of the possible impact of changing family constellations (e.g. sibship size) on the Flynn effect.
