Tailored for both consumers and neurotech developers/researchers, this evidence book provides an in-depth exploration of the scientific basis of neurotech based on systematic reviews. It emphasizes the need for consumers to approach them with caution, given the current lack of evidence supporting many claims. In other words, this book aims to provide accurate information to the public, improving transparency, and helping consumers make informed decisions about the use of neurotech products.

This evidence book was produced as part of the "Liberation from Biological Limitations via Physical, Cognitive and Perceptual Augmentation (Project Manager Ryota Kanai)" project for Goal 1 of the Cabinet Office Moonshot Research and Development Program, "Overcoming limitations of body, brain, space and time" by 2050. The funders, Japan Science and Technology Agency and the Cabinet Office, are not involved in any part of this book.
