It is informative and scary to pay attention to how our personal models of the world inform and sometimes bias our cognition. This morning I see this image on my walk to the coffee company and my mind immediately labels this image – adult mower teaches its young. You probably don’t get this until you take a second look. Yes, the mowers are not actually interacting, but the cluster of little mowers around a much larger mower fits with some general model I must have. Part of human intelligence is driven by pattern recognition. An important part of human intelligence (metacognition) is also recognizing that situations we place in a category have not been accurately located. Humor sometimes depends on the recognition of these interesting misplacements. There is a lesson here. Some assignment of situations to concepts are not appropriate and the more general model needs to be refined. Be aware that your experiences and background influence how you interpret new inputs. Not all Muslims and women who cover their heads are terrorists.
