It is necessary to add that researchers in the psychosocial tradition have not held much respect for glib notions of flaps like mass hysteria e.g. as when expressed back in 1954 by the French psychiatrist George Heuyer. By the time they were writing, doubts had already been expressed. Mark Rhine in the Condon report and Robert Hall for the 1969 AAAS symposium on UFOs looked at certain classic episodes of mass hysteria or hysterical contagion like the June bug epidemic, the Seattle windshield pitting epidemic, and the Mad Gasser of Mattoon, to see how well they could serve as explanatory models for what is going on with the ufo phenomenon. Neither developed the idea very far and Hall discerned several difficulties in comparing these phenomena, probably the most notable being the fleeting character of those model social epidemics. Michael Swords later offered additional observations that essentially killed it for researchers on both sides of the debate. In a recent discussion of Great Britain's Warminster flap of the 1960s, the researchers echo these developments and prefer to discuss the flap as a collective delusion maintained by rumor and gossip. Given the general decline of respect for the broader concept of hysteria in modern psychology; this seems just as well.
