Strange loop
Systems that refer to themselves produce mind-like behavior.
A strange loop is Douglas Hofstadter's term for a structure in which moving up or down through levels eventually brings you back to the starting point. The system ends up representing itself. Escher's drawing of two hands drawing each other is a favourite picture of the idea, as are Bach's endlessly rising canons.
Hofstadter's bold claim, developed in Gödel, Escher, Bach and later in I Am a Strange Loop, is that consciousness works this way. A brain builds models of the world, and among them is a model of itself, which in turn shapes how it builds models. That self-referring cycle, he argued, is where an inner perspective comes from. Once you grasp the shape, you start seeing versions of it in language, law, markets and even in thinking about your own thinking.
The limit is that not every loop is strange. A thermostat switching on and off is feedback. A function that calls itself is recursion. Hofstadter reserved the term for cases where self-reference crosses levels and produces something new, such as meaning or a point of view. Labelling every circular process a strange loop empties the idea.
The concept links to the next card, which applies it directly to the sense of being an I.
Example
A company publishes an index of the most influential firms, and being on it makes firms more influential, which affects next year's index. The ranking describes the system and changes the system it describes. Watching how the list feeds back into itself is a small, everyday view of a strange loop.

Pick one system you are part of this week, like a team or a feed, and look for a place where a description of it changes the thing itself.
