I think we are fundamentally too tribal and violent as a species. I think there is nothing we can do against millions of years of natural selection favoring the furthering of your kin at the expense of your species. We aren't wired for civilized society, it has to be learned and ingrained and even then, we revert to our tribal tendencies at the slightest encounter with an unknown.
Without knowing what the actual answer to survive the filter might be, it's worth noting that across the entire universe, it's surely statistically unlikely that not a single species has made it through to the other side.
If they have broken through, and assuming that they would view as a positive the breakthrough of other species through the "great filter" (and hence the collective uplift of intelligent life in the universe) - there's an implication that maybe what is required for breakthrough cannot - by definition - be transferred (in a similar way that children have to learn some lessons for themselves no matter what your parenting style).
Either that, or they haven't gotten to us yet, or they're species-ist and quite happy to be the only ones past the filter.
