Cryptic Effects at a Distance: Constructing Causal Claims in Fetal Epigenetic Programming Research

Abstract: This paper offers a critical analysis of three touchstone research streams linking epigenetic markers with prenatal exposures and later life health in human populations: studies of individuals gestated during the Dutch Famine; research on individuals prenatally exposed to a 1998 ice storm in Quebec; and studies of the offspring of Jewish Holocaust survivors. In human studies, maternal intrauterine effects are what I call cryptic: they are small in effect size, vary depending on ecosocial context, and occur at a great temporal distance from the initial exposure. The fetal epigenetic programming hypothesis functions as a narrative glue that coheres disparate cryptic findings into plausible causal stories. Through close analysis of these research streams, I examine precisely what inferences scientists believe epigenetic studies can support, and how, in practice, scientists construct causal claims in fetal epigenetic programming research, despite the crypticity of their findings.
