Exploring disparities in self-reported knowledge about neurotechnology.

With advances in neurotechnology and its use for medical treatment and beyond, it is important to understand the public's awareness of such technologies and potential disparities in self-reported knowledge, because knowledge is known to influence the acceptance and use of new technologies. This study utilizes a large sample (N = 10,339) to depict the existence and extent of self-reported knowledge of these neurotechnologies and to examine knowledge disparities between respondents. Results show that most respondents self-reported at least some knowledge of ultrasound and electroencephalography (EEG), but limited knowledge of BCIs. Prior use, being a healthcare professional, and health literacy increased the odds of self-reporting some knowledge. Also gender and age disparities exist. These findings may help identify uninformed groups in society and enhance information campaigns.
