In a study conducted at Yale, graduate students were asked to rate their understanding of everyday devices, including toilets, zippers, and cylinder locks. They were then asked to write detailed, step-by-step explanations of how the devices work, and to rate their understanding again. Apparently, the effort revealed to the students their own ignorance, because their self-assessments dropped. (Toilets, it turns out, are more complicated than they appear.) Sloman and Fernbach see this effect, which they call the “illusion of explanatory depth,” just about everywhere. People believe that they know way more than they actually do. What allows us to persist in this belief is other people. In the case of my toilet, someone else designed it so that I can operate it easily. This is something humans are very good at. We’ve been relying on one another’s expertise ever since we figured out how to hunt together, which was probably a key development in our evolutionary history. So well do we collaborate, Sloman and Fernbach argue, that we can hardly tell where our own understanding ends and others’ begins. “One implication of the naturalness with which we divide cognitive labor,” they write, is that there’s “no sharp boundary between one person’s ideas and knowledge” and “those of other members” of the group.
"Going green" has become a topic of increased attention lately, but it's nothing new to knowledge management. By its nature, knowledge management promotes efficiency and optimal use of resources, which often reduces the amount of energy required to achieve a given goal. What has changed is the heightened awareness of those benefits. That awareness is creating new interest in KM solutions that can improve business performance while reducing environmental effects. Knowledge management also plays a role in the software tools that help companies improve their energy management, embedding expertise in algorithms to optimize use of office equipment and energy in buildings.
