Friends would love to discuss the following.
Hormesis in the lit. seems to lack in rigor as a phen (2nd mistake, aside from missing local convexity). It is defined by a compensatory reaction, which conflicts with evolutionary filtering (antibiotic resistance works by destroying the weak faster than the strong). So there are:
1) hormetic antifragility,
2) evolutionary antifragility (often mistaken for hormesis),
3) payoff antifragility (say, financial options).
All three like increase in randomness, but function different ways.
