Critics have argued that social constructionism generally ignores the contribution made by physical and biological sciences or misuses them in social sciences. As a theory, social constructionism particularly denies the influences of biology on behaviour and culture, or suggests that they are unimportant to achieve an understanding of human behaviour, while the scientific consensus is that behaviour is a complex outcome of both biological and cultural influences. It equally denies or downplays to a significant extent the role that meaning and language have for each individual, seeking to configure language as an overall structure rather than an historical instrument used by individuals to communicate their personal experiences of the world. This is particularly the case with cultural studies, where personal and pre-linguistic experiences are disregarded as irrelevant or seen as completely situated and constructed by the socio-economical superstructure.
