All tagged cognition

Erik Hollnagel does Cognitive Systems Engineering research in the area of human performance and accident analysis / prevention. He has a brief write-up on The principle of Efficiency-Thoroughness Trade-Off (ETTO) that I found interesting. The bottom line: it is the system that has to be diagnosed to understand why an efficient "short cut" failed when it normally worked just fine.

I came across "The knowledge management puzzle: Human and social factors in knowledge management" from the 2001 IBM Systems Journal. The authors use the metaphor of a jigsaw puzzle to motivate their discussion, suggesting that IT is only one of many pieces to the puzzle for knowledge management. And they also acknowledge that there are pieces they may not know that create still other pictures when the pieces come together. They also provide a great set of references for the curious.

Rashmi Sinha put together "A cognitive analysis of tagging (or how the lower cognitive cost of tagging makes it popular)" that I found to be illuminating. The short version: tagging is a simpler process because it lets us annotate something with all the concepts that it fires in our brains. Categorization forces us to pick one of those concepts.
