Symptom‐validity testing has been used to detect feigning in patients claiming sensory and memory deficits. Such patients typically give significantly fewer correct responses on forced‐choice testing than would be expected by chance. Some subjects have been able to understand the rationale and respond at the chance level. Some have evaded detection by elaborations of the technique which seek evidence of non‐randomness in the sequence of correct and incorrect responses. This paper reports the stratagem used by one such subject and a further elaboration of the technique by which it was detected.
