And the overwhelming majority of societies with initiation rights and rituals are not world-controlling cabals. Turns out people just like having rituals (and afterparties).
Where did I say they were a cabal that controlled the world? There are many famous and influential people that are a member of that society, and they swear oaths and go through initiation rituals. Believe whatever you'd like!
And most of those people are famous and influential because of their accomplishments in engineering, which it is an honor society for.
Wait til you hear about Phi Beta Kappa. Sometimes they even have pizza parties. Probably.
