Of course. My point is that observing if the discount rate changes with the risk tells you if the agent is rational or irrational, not if the discount rate is all instrumental or partially terminal.
Stepping back for a moment, terminal values represent what the agent really wants, and instrumental values are things sought en-route.
The idea I was trying to express was: if what an agent really wants is not temporally discounted, then instrumental temporal discounting will produce a predictable temporal discounting curve—caused by aging, mortality risk, uncertainty, etc.
Deviations from that curve would indicate the presence of terminal temporal discounting.

Agreed.
