Credibility Before
Testimony.

The Supreme Court recognised appearance as a due process concern fifty years ago, in Estelle v. Williams (1976). In the decades since, the profession has built a sophisticated understanding of how jurors perceive the people in front of them — and developed no comparable framework for what being perceived does to those people in return.

Jennifer Heinen identifies that gap and builds the framework to close it. Her thesis is precise: the observer is theorised; the wearer is handled by instinct. Courtroom appearance operates through two mechanisms — how a presentation reads to the jury, and what it does to the person wearing it — and in a courtroom these are coupled through the body. A presentation optimised for the jury while ignoring the wearer can defeat itself on the jury’s own terms.

The coupling problem and the observer–wearer framework are her original contribution: a structured model for the variable the profession has long half-known and never organised. The empirical claims are grounded in cited research, from Princeton social-perception studies to the post-replication enclothed-cognition literature. The synthesis is hers.

To the juror it does not feel like a judgment being constructed; it feels like simply seeing what kind of person this is.
