Abstract
BACKGROUND: The relational development systems (RDS) metamodel embodies a newly recognized scientific paradigm that stands in contrast to the nature-nurture split. It suggests that the bidirectional relationship between an organism and its environment must be the central focus of scientific inquiry. MAIN BODY: RDS theorists suggest scientists have a moral obligation to benefit human kind. However, the potential for interventions that appear efficacious to simultaneously instigate an undesirable outcome suggests that moral clarity might not always exist in scientific practice. Contrasting RDS perspectives with life history theory highlights a pertaining disparity in approaches. CONCLUSION: While the RDS metamodel posits many premises necessary to contemporary research, it may not yet be pragmatic to impose moral obligation on the sciences.
