The great filter might simply be a belief in non-interference.  Many people
think this is unlikely because they believe there is no reason a bunch of
random alien civilizations would agree on this, but I think nearly all
alien civilizations will reach a state of super-intelligence before it
achieves interstellar travel.  It's been said that when intelligent people
disagree it is due to a difference in data.  If we assume these
civilizations are super-intelligent, then all or most of them reaching a
common consensus becomes much less likely.

Perhaps.  But it is impossible to rule out the possibility that we are
already members of such a civilization, who choose to momentarily forget
our true identity.
