It seems that the nudge from each individual can either contribute to the resonance or detract (constructive vs destructive interference).

There are many ways this can unfold. For example, groups of people with similar values, mindsets, or skills can much more easily manifest significant constructive interference.

As you note, the speed/frequency of the wave seems much faster now with our new communication technologies. These changes, along with the increased scale of human population, introduce new patterns for both constructive and destructive interference that we need to understand and handle.

Of course, if we try to solidify the metaphor further... this wave is likely to have enormous dimensionality and be composed of components that would absurdly difficult to even begin measuring. But it's a great metaphor and certainly got me thinking.
