Dror has another recommendation that illustrates the same decision hygiene strategy: examiners should document their judgments at each step. They should document their analysis of a latent fingerprint before they look at exemplar fingerprints to decide whether they are a match. This sequence of steps helps experts avoid the risk that they see only what they are looking for. And they should record their judgment on the evidence before they have access to contextual information that risks biasing them.
