Welcome to anthropology, the softest of the soft, soft, sciences.
Have to disagree with you here. Anthropology is traditionally broken up into four disciplines: cultural anthropology, linguistics, physical anthropology, and archaeology.
The latter two are not "soft" in any respects. I split my Ph.D. between the two and I can assure you this.
Perhaps you are thinking of the soft aspects of anthropology, along with sociology, psychology, theology and those other squishy subjects?
