Here we have another exercise in storytelling that helps users “get it.” Moreover, we are presented with an analogy that demonstrates quite well just how powerful metaphorical extension of concepts can be. The communication power tool that is the metaphor bridges the gap between a schema that you are familiar with and a schema that you are unfamiliar with.
A schema is a systematic knowledge representation you store in your minds, by the way. Very roughly speaking it consists of a set of pieces of information that are linked together. When a schema of walking the dog is invoked in your mind, you automatically activate information like owner and leash among other things that all pertain to your knowledge of what walking the dog means.
In this video your knowledge of walking the dog is juxtaposed with a concept where your knowledge may be less substantial. Your mind is then able to piece together the gaps in your schema of climate change with information from the familiar schema of walking the dog. How cool is that!
Well, the problem is that when you use a bad metaphor, the minds of your audience fill in the blanks of their knowledge with erroneous information. That’s why metaphors can be a powerful tool of misinformation and deceit. Promise you’ll use your powers for good, will you?
