Our aim has been to study twinship as a normal form of human experience—rather than as deviant or dysfunctional compared to the experiences of singletons. We wanted to identify key cultural themes that shape the experiences of twins but that are largely ignored by researchers. In 2014, I published the results of our research in my book Twins Talk. After more than a decade exploring the nature of twinhood, we came away with richer insights into the lived experiences of twins and deepened the way we relate to each other.
