The executive’s argument isn’t about whether or not a medical publication is reliable, so this is just irrelevant.

Firstly, we don’t know if a majority of reliable sources find herbal tinctures to be ineffective, so this doesn’t apply to the executive’s premises. Secondly, this still doesn’t tell us anything about profitability.

The executive clearly did make a determination about whether promoting herbal tinctures will be profitable, so the argument can’t conform to this principle. Also, the executive didn’t just consult publications—what about the advisory staff?

The executive’s argument never mentioned anything about adverse medical effects, so this is irrelevant.

In other words, the herbal tinctures have been declared ineffective by several reliable authorities, so marketing them won’t be profitable. The executive’s argument conforms to this principle by incorporating it as an assumption bridging premises to conclusion.
