This assertion violates the time-honored maxim that novel explanations for a phenomenon must not be advanced unless well-established, simpler explanations have been excluded. Here, there is a simple and entirely reasonable explanation for the participants’ lack of recall: namely, that nothing particularly memorable occurred during their childhoods. In other words, demonstrating traumatic amnesia requires excluding the possibility that the participants merely forgot unremarkable events. Dr. Chu and colleagues failed this requirement.
