...okay, if this is the actual state of speculation, either Keltham is really missing something, people in Golarion really don't Science, or the correct answer is an infohazard getting buried.

Theory one seems like it would be incredibly easy to test in opposition to the others, by just taking a normal unimportant kid and healing them once a day... well, maybe you need to get hurt for the healing to count, but that test could at least rule out the version where regular healing does it without injury being needed first?

And if the pilot experiment returned NO on the added toughness, get one of the higher-grade masochists, or just use anesthesia, and test it with actual injuries on them, starting after they were adults at age 13, and could sign up for an experiment?

Do clerics who use five bursts of positive energy per day, somewhere that needs the healing, end up some of the toughest people around?  If not, are any of those clerics masochists who could injure themselves first or have their sadists do that before each healing?

Does being incredibly rich make you tougher, as it would if it was just importance?  Are there any famous cases of people losing all their money and then immediately losing the extra toughness?  Did the girls on Project Lawful suddenly get much tougher once they were much more important?  Should they get a dagger right now and test whether Keltham is important enough to have the extra toughness?

Have they quantified strength of aura, quantified how hard it is to do a standard amount of damage to a paid volunteer, and checked whether aura strength looks directly proportional to extra toughness?

How can people possibly not already know about whether some of these theories are true or false?

Keltham won't explicitly mention his suspicion about the correct answer being a buried infohazard, but will ask Carissa about the obvious tests or checks on the other theories, flexing his tickling-fingers in a threatening way as he does.
