whereas cognitive liberty is concerned with protecting an individual's freedom to think however they want. Cognitive liberty seeks to protect an individual's right to determine their own state of mind and be free from external control over their state of mind, rather than just protecting the content of an individuals’ thoughts. It has been suggested that the lack of protection of cognitive liberty in previous human rights instruments was due to the relative lack of technology capable of directly interfering with mental autonomy at the time the core human rights treaties were created. As the human mind was considered invulnerable to direct manipulation, control or alteration, it was deemed unnecessary to expressly protect individuals from unwanted mental interference. With modern advances in neuroscience and in anticipation of its future development however, it is argued that such express protection is becoming increasingly necessary. Cognitive liberty then can be seen as an extension of or an "update" to the right to freedom of thought as it has been traditionally understood. Freedom of thought should now be understood to include the right to determine one's own mental state as well as the content of one's thoughts. However, some have instead argued that cognitive liberty is already an inherent part of the international human rights framework as the principle underlying the rights to freedom of thought, expression and religion. The freedom to think in whatever manner one chooses is a "necessary precondition to those guaranteed freedoms." Daniel Waterman and Casey William Hardison have argued that cognitive liberty is fundamental to Freedom of Thought because it encompasses the ability to have certain types of experiences, including the right to experience altered or non-ordinary states of consciousness. It has also been suggested that cognitive liberty can be seen to be a part of the inherent dignity of human beings as recognized by Article 1 of the UDHR. Most proponents of cognitive liberty agree however that cognitive liberty should be expressly recognized as a human right in order to properly provide protection for individual cognitive autonomy.

United States, in which the Supreme Court examined whether the court had the power to make an order to forcibly administer antipsychotic medication to an individual who had refused
