Now let us turn our attention to the child who has had a close and loving relationship with a parent whom they no longer see. And let us further assume that the child is told that the reason that the parent is gone is that they simply do not want to be with the child, such information would be quite hurtful and damaging in and of itself.
Now let us assume that this same child is told that the absent parent who suddenly appeared to not want to see them any more was actually a dangerous and violent person and that the child had been fooled into thinking otherwise, and that this same parent was actually a sly and deceitful manipulator. Absent contact with that parent, even the most bonded child to this parent will begin to wonder and harbor suspicions.
The phenomenon of “confirmatory bias” comes into play here.
