### _Exsupero Ursus_
> Chapter 9 p.195
Hubbard uses _exsupero ursus_ to describe the tendency of his detractors
to dismiss quantitative methods as inappropriate to their industry-specific risks.
He provides another analogy in which one car is picked of two (ordinary) cars
because the other car can't fly.

Based on this strawman it is clear Hubbard believes his detractors are _correct_
that qualitative methods can not capture the entire nuance of risk probability,
but that they are failing to acknowledge that their preferred alternatives
are not demonstrably more effective at doing so.
The nuance Hubbard dismisses without addressing is the possibility of model _improvement_.
A most competant detractor would be aware of the apparent contradiction
A most competent detractor would be aware of the apparent contradiction
but argue that their methods will eventually surpass quantitative methods
if they are further developed.
Such a position would additionally contextualize Hubbard's observations
that detractors become emotional in their defense.
To them, Hubbards methods represent an attractive short-term gain
excluding a long-term payoff.

Hubbard's dismissal rubs me wrong
because it reads exactly as he describes the "at least we're doing _something_" argument
