One of the fresh new things on the therapy block is the Ideal Parent Figure Protocol.
The idea is that you do guided meditations in which you imagine parent figures who are perfectly attuned to you. Over time, so the theory, this will rewrite your attachment wounds and turn you into a happy psychologically healthy person.
While I keep meeting people who profit from it, I am deeply uncomfortable with IPFP.
Because it ignores lineage.
Instead of helping us make peace with and sense of where we come from, IPFP assumes that who we are can be isolated from our actual parents and peers. The fact that IPFP is even thinkable in the first place bears witness to and perpetuates the atomization, isolation, alienation of 21st century Westerners.
As the old feminist slogan goes: “The private is political.”
And so is our decision to treat ourselves as islands.
What I suggest, instead, is the Real Parent Figure Protocol. Grieving our attachment wounds not as a result of our parents’ individual failings, but as a shared burden that they have carried before us, just as their parents and their parents and their parents have.
In RPFP, we start with feeling all that teenage rage of “How could you do this to me?”, and progress through the stages of grief all the way towards a more differentiated view of our ancestors. We learn to see their strong and weak moments side by side. And, we learn to see that we are no better or wiser than those who hurt us. That they did the best they could. In the end, we arrive at an equilibrium where there’s no demons to exorcise, no scapegoats to exile. We earn the mature view of “we’re all in this together”. We become responsible adults capable to take care of our kin and the world we live in.
But why should we do this, when the IPFP is right there, easy, straightforward, and promises healing without the awkwardness of becoming intimate with flawed humans?
Because our individual suffering has a systemic, collective dimension. When we heal our own wounds, we heal the larger systems we are part of. And when we heal our relationships to family, community, and the world, we heal ourselves. Same thing.

Hurt people hurt people, and healed people heal people.
Therefore, we might want to do the courageous thing and make peace with our lineages. Instead of retroactively giving ourselves up for adoption, we might want to grieve the wounds we actually suffered and forgive the ancestors we actually have.
If we do real attachment healing, if we accept our woundedness and its historicity rather than try to simulate the wounds away - who knows? Maybe that constant familiar feeling of emptiness, of alienation, of drifting around in a hostile world, can finally leave us. Maybe, we can experience ourselves, once again, as a cell in the body of Gaia.
I'm curious where your impression of IPF has come from, because to me (as someone who's been doing facilitated IPF for a bit more than half a year) it feels like you're arguing against a strawman. IPFP ≈ RPFP, IME.
My experience is that doing this practice brings up pretty rough memories and emotions–it hurts! Because hard psychic material is the stuff that blocks to learning secure functioning are made from. Maybe if someone was doing it without a facilitator, it could be bypassy, but the people I've introduced to Dan Brown's guided meditations on YouTube pretty uniformly end up thinking back to real difficult situations they haven't finished digesting yet, and they found it hard going...
Anyway, for me it's been anti-bypassy. I've not experienced an increase in blaming my parents, kinda the opposite: I've gotten in touch with the ways that I blame others reflexively and don't take responsibility for myself. I've felt through more raw grief and shame than I was really prepared for. And of course, in the end, the reason I'm doing it is to show up with more capacity and responsibility in the real relationships I have, which seems to be happening, slowly. In the end it's targeted meditative therapy, building a safe-ish container and then triggering me repeatedly, and helping me to imagine different possibilities for what could happen and how might I act differently.
The thing about methodological nuclear family-ism you mention ("grieving our attachment wounds not as a result of our parents’ individual failings, but as a shared burden that they have carried before us"), I don't think that's real either. IPF doesn't take a position on where the burden comes from–because the practice is to imagine new possibilities. The material that comes up for me while doing that is sometimes about my real parents, but it's also about my friends and lovers (or exes of either type). And I wonder quite a lot about everyone's family histories in that process too...
I am pro real parent figure also tho I was thinking a different direction
