When introducing complexity, I find the standing ovation example (from Scott and Miller) is a great, accessible point of entry.

As the performance ends, each audience member must decide whether or not to stand. Of course, if the decision to stand is simply a personal choice based on the individual’s own assessment of the worth of the performance, the problem becomes trivial. However, people do not stand solely based upon their own impressions of the performance. A seated audience member surrounded by people standing might be enticed to stand, even if he hated the performance. This behavioral mimicry could be strategic (the agents wants to send the right signal to the lecturer), informational (maybe the lecture was better than he thought), or conformal (he stands so as to not feel awkward). Regardless of the source of these peer effects, they set the stage (so to speak) for interesting dynamic behavior.

If you want to reflect/apply, I encourage you to play this video below in slow motion (and mute, YT does not do a good job at adjusting audio for slower playback : )

You can dig deeper through this (and the whole course for that matter)
