IIRC, the wave of suicides was confined to the members of the club, so they actually knew what was up. On the other hand, there was at least a strong hint that it was going to spread globally, so you have a point there. On the other hand, this would still destroy a lot of experimentation in the field of particle physics... although I guess it would be interesting to poke at the edges of the effect?
