Phi, a collegiate secret society at Princeton University

While secret society membership is relatively public at some schools, Princeton's historical secret society rolls are very secretive because of Woodrow Wilson's ban on clandestine organizations and his threat to expel secret fraternity members from Princeton.

One such society is Phi (pronounced fē),

a society dating to 1929 when members of the Whig society splintered off after the merger of the Whig and Cliosophic debating societies.

Phi's membership is secretive and difficult to discern because no more than ten active "Phis" exist at one time: Phis usually receive offers at the end of their third year.

As an adaptation to Princeton's stringent anti-society rules, each active class does not meet the preceding class that selected it until the First of June (after their first Reunions and before graduation).

1.6... is the Golden Ratio, hence the name Phi.

Another society is the exclusively female Foxtail Society, founded in 1974 soon after Princeton began admitting women in 1969.

The society was founded in response to the lack of eating clubs open to women.

While admittance numbers have changed over the years, Foxtail selects anywhere from 10 to 15 women to become members at the end of their junior year.
