increasing the information-sharing abilities of group members using “electronic collaborative tools” might enhance the intelligence of the group itself (without necessarily increasing the intelligence of individual group members).

increasing the raw intelligence of individual group members cannot guarantee a smarter group. A group of cognitively enhanced individuals with extremely high IQs (because of their enhancement) thus might fail to outperform a group of “normals” if those “normals” prove to be more socially sensitive than their enhanced rivals.

the central component of the extended mind thesis is called the Parity Principle. It states that “if, as we confront some task, a part of the world functions as a process which, were it to go on in the head, we would have no hesitation in accepting as part of the cognitive process, then that part of the world is (for that time) part of the cognitive process.”

Thus, according to the Parity Principle, inanimate objects like a pad of paper, a calculator, a computer, Wikipedia, an iPhone, and so on, can all, under just the right conditions, constitute a literal component of one’s cognitive system – of one’s mind.

another mind can indeed become a feature of one’s own cognitive system (on the condition that the Parity Principle is true

Our minds are made in such a way that trauma, and negative experience is slowly buried up, or forgotten. Our minds do seem designed with self preservation measures to try and protect our psyche. Now with a memory that is always accurate, and that is always accessible, what will that do to our minds? My concern is what our limitations add to our selves. I am unsure of what the world would be like if I didn't forget things. There are somethings we choose to forget, or ignore, or believe despite the evidence. Our emotions do seem somewhat disconnected from our experiences, especially as time goes on. Stockholm Syndrome is a wonderful example, despite the worst possible conditions a loyalty and an affection grows between a captor and their captive.

With the ability to share memories, or worse, to forcibly access others memories, this wonderful world enhancement will help us build, may be utterly devoid of privacy. A world where nothing is sacred, except knowledge, and that you may no longer own your own life. Simply, everyone's life, everyone's knowledge and everyone's experiences, may simply become public domain.
