We can look for flock-like behavior in patterns of speech too. This occurs when one idea or person follow another, for example: “We live on 1 planet Earth, but our footprint on average is 1.5.” And then: “This will lead to turmoil and chaos, and eventually human migration.” – John Sterman (whose talk on Systems Thinking and Sustainability is the source of all these images…) The words come out with causal relation, and one concept FITS with another to form a gesture or new shape of it’s own, only a pattern because of grouping.
