In 1995-1996, three psychological researchers conducted a study on false memories. Their research involved describing a fictitious "memory" of having been lost at a shopping mall as a child, along with true childhood events, in a series of interviews with their subjects. The subjects eventually believed they remembered the incident truly happening. This study cast serious doubt on so-called "recovered memories." However, critics challenged the study on the basis that the subjects may truly have become lost as children, in which case they were really recovering lost memories.
What could be done in a further study to support the theory that people can easily be implanted with false memories?
