title: Some methodological considerations for the behavioral genetic analysis of work attitudes.
abstract: In a recent article, Arvey, Bouchard, Segal, and Abraham (1989) argued that about 30% of the variance in job satisfaction was accounted for by workers' genetic make-ups. To demonstrate this, they examined a group of monozygotic twins who had been reared apart. Although this method has been used widely in behavioral genetic research, it contains many hidden threats to validity, which could render suspect numerical estimates of either environmental or genetic effects. We examine some of the threats associated with this type of twin research, emphasizing the problems involved in quantifying the heritability of job satisfaction.
