- Inputs?
- Outputs?
- Switches, junctions, choices?
- Different outcomes? Consequences of Decisions?
- How are things related?
- Flow chart, system, map or circuit?

NETWORK MAPPING
- Start with a Wikipedia or other article on a subject
- Note what it is connected to
- Continue noting connected articles until...

Feedback Loop
A system where the output loops back on itself and feeds into the input. This often creates a runaway effect. Loops that get bigger and bigger are called positive feedback loops. Loops that get smaller and smaller are called negative feedback loops.
Feedback loops examples
positive feedback loop

The populations keep each other in balance, feedback loops are kept under control.

Positive feedback loop
Feedback loops in audio and video
The amplified audio goes back into the mic and gets amplified again, into infinity, which sounds like this.
The video monitor is being filmed, so a monitor with an infinite number of monitors inside of it appears, which looks like this.
How to avoid A/V feedback loops?
Keep the input away from / not pointed at the output!
