  We show that the eclectic "Boogaloo" extremist movement that is now rising to
prominence in the U.S., has a hidden online mathematical order that is
identical to ISIS during its early development, despite their stark
ideological, geographical and cultural differences. The evolution of each
across scales follows a single shockwave equation that accounts for individual
heterogeneity in online interactions. This equation predicts how to disrupt the
onset and 'flatten the curve' of such online extremism by nudging its
collective chemistry.
