Psychology has developed many useful research methods to study nature versus nurture, including twin studies and adoption studies.
If is a weapon in the struggle between classes, then the universities are weapons factories, and their teaching and research faculties are the engineers, designers, and production workers. Although psychology in the 21st century is a scientific field that has developed many methods to investigate psychological phenomena, and our understanding of development has become more sophisticated, the nature versus nurture debate remains very active. . Furthermore, policy makers must remember that science including psychology is a field of study that attempts to provide more and more accurate knowledge over time. This heated debate has social and political implications. However, such appliance appears to construct reality.
