Carl: Researchers who perform operations on animals for experimental purposes are legally required to complete detailed pain protocols indicating whether the animals will be at risk of pain and, if so, what steps will be taken to minimize or alleviate it.
Debbie's Conclusion (So)
Pain protocols are unnecessary for human beings.
Debbie's Evidence (consider this)
If a doctor wants to schedule surgery for a person, they can simply tell the patient what pain to expect and the patient can decide whether or not to undergo the operation.
Evaluate
Given that ... doctors scheduling surgeries for humans can just inform the patient what pain to expect and get the patient's consent,
How could we still argue that ... pain protocols can sometimes be necessary for humans? (i.e. how could there still be times when medical doctors/researchers would need to fill out a form about what pain would be involved in a procedure and what steps would be taken to minimize the pain?)
Maybe we need to operate on kids or on adults who lack the mental clarity to understand the doctor as they explain what pain to expect.
Maybe we want to do some procedures on unconscious people, so we can't wake them up to get their consent.
Maybe insurance companies or medical researchers would benefit enough from having pain protocols filled out for every operation that it's worth requiring them sometimes.
Goal
We need to think of some situation where a human couldn't just listen to what pain should be expected and consent or decline the surgery, or a situation where even if they can consent, we still want the pain protocol for some other reason.
