  1. Lay understanding of genetics : a test of a hypothesis.

    Article - En anglais

    There have been growing calls for more education in genetics for the public and in schools.

    However, studies of the public, school children, and those who have received genetic counselling show that understanding of scientific genetics is very limited.

    A hypothesis to explain this limited understanding is proposed and tested.

    It is argued that there is a widespread lay knowledge of inheritance which conflicts in a number of aspects with scientific explanations and which impedes the assimilation of the latter.

    It is suggested that this lay knowledge is derived from concepts of the social relationships of kinship.

    Concepts of kinship ties are sustained by everyday social activities and relationships which may make them resistant to change.

    A prediction which follows from the hypothesis that the lay understanding of genetics is derived from concepts of family and kinship relationships is that closeness in genetic terms will be determined by the closeness of the family ties of social relationship and social obligation.

    While the proportion of genes shared with parents, children, and sibs is, on average, the same, kin relationships and obligations are much stronger between parents and children than between sibs.

    The hypothesis was tested in a questionnaire study of two samples of adult women (n=64 and n=113) and one of social science students (n=73). (...)
