Psychology shows this faith to be misplaced. Perception is selective and shaped by expectation; memory is not a photograph but a reconstruction that fades, fills its gaps with inference, and is molded by every suggestive question put to it; the confident witness may be confidently wrong, and the very sincerity of his belief is no guarantee of its truth. I have shown in the laboratory how easily a remembered scene is distorted, how a leading question implants what was never seen, how an innocent man may be led to a false confession. The law has taken centuries of rules of evidence to guard against the liar; it has scarcely begun to guard against the honest witness who errs. The psychologist has a place at the bar of justice — not to replace the judge, but to tell the court what the mind can and cannot faithfully report. Justice that ignores the psychology of testimony is building on sand.","paragraphs":[[{"t":"The courts proceed as though the honest witness who swears he saw a thing therefore saw it, and remembers it as it was.","n":[]},{"t":"Psychology shows this faith to be misplaced.","n":[]},{"t":"Perception is selective and shaped by expectation; memory is not a photograph but a reconstruction that fades, fills its gaps with inference, and is molded by every suggestive question put to it; the confident witness may be confidently wrong, and the very sincerity of his belief is no guarantee of its truth.","n":[1]}],[{"t":"I have shown in the laboratory how easily a remembered scene is distorted, how a leading question implants what was never seen, how an innocent man may be led to a false confession.","n":[]},{"t":"The law has taken centuries of rules of evidence to guard against the liar; it has scarcely begun to guard against the honest witness who errs.","n":[]},{"t":"The psychologist has a place at the bar of justice — not to replace the judge, but to tell the court what the mind can and cannot faithfully report.","n":[]},{"t":"Justice that ignores the psychology of testimony is building on sand.","n":[2,3,4,5]}]],"texts":"On the Witness Stand: Essays on Psychology and Crime (1908 — the illusions of memory and perception, false confessions, suggestion, the detection of deception).

He founded the field. The contested part is historical and rhetorical: in 1908 his specific claims and his promotion of the psychologist's courtroom role outran the evidence then available and were premature, drawing John Henry Wigmore's celebrated satirical rebuttal on behalf of a legal profession not ready to cede ground. So the vision was right and ahead of its time; the confidence with which he pressed it in his own day was greater than his evidence yet warranted.","era":"1863-1916","discipline":"Psychology","refs":[{"n":1,"work":"On the Witness Stand","page":"","canonical":"","quote":"Not one of my mistakes was of the slightest consequence.
