I probably should have clarified that in the case of raws, I count as “middle” everything which is not on the border, that is not first or last raw.
This caveat actually plays in the situation of the universe anthropic fine-tuning by many parameters. The number not-perfectly-fine-tuned universes is much larger than the set of fine-tuned ones. This means lower concentration of civilizations in space compared with “optimal universe”. Seems to be solution of the Fermi paradox.

Thank for the link.
