Keeping secrets from parents: on galloping horses, prancing ponies and pink unicorns.

We identify the need for a new wave of research on adolescent secrecy in their relationship with parents that relinquishes the focus on the nomothetic objective of finding general principles. This third wave builds on novel insights on three fallacies committed in previous waves of research: (1) between-person effects do not necessarily provide insights into within-family processes (the ecological fallacy), (2) within-family processes are not necessarily homogeneous across adolescents and families (the one size fits all fallacy), and (3) longer-term effects are not necessarily identical to short-term processes (the galloping horse fallacy). This approach promises to provide us with a more person-specific understanding of adolescent secrecy from parents, which enables more tailored insights as to when and for whom secrecy is bad versus good.
