 Direct interventions: The ability to directly manipulate our brains to control our thoughts or behavior is an obvious threat to our autonomy (Gilbert, 2015; Walker and Mackenzie, 2020). Some of our neurotechnologies offer that potential, although these sorts of neurotechnologies are invasive and used only in cases where they are medically justified. Other types of interventions, such as the administration of drugs to calm a psychotic person, may also impact autonomy.
