# True Lie Detection by Sam Harris > “The development of mind-reading technology is in its infancy, of course. But reliable lie-detection will be much easier to achieve than accurate mind reading. Whether on not we ever crack the neural code, enabling us to download a person’s private thoughts, memories, and perceptions without distortion, we will almost surely be able to determine, to a moral certainty, whether a person is representing his thoughts, memories, and perceptions honestly in conversation. Compared to many of the other hypothetical breakthroughs put forward in response to this year’s Edge question, the development of a true lie-detector would represent a very modest advance over what is currently possible through neuroimaging. Once this technology arrives, it will change (almost) everything.” > **— Sam Harris**, *2009, Edge Annual Question, “What Will Change Everything?”* ## Sources and Context - **Direct Edge response and surrounding essay:** [TRUE LIE DETECTION](https://www.edge.org/response-detail/11481) — Edge published this exact passage in its 2009 Annual Question collection, *WHAT WILL CHANGE EVERYTHING?*.
