Arrogance unfortunately isn’t rare in the medical community and it cuts both ways. It can lead doctors to dismiss PFS without really thinking about the situation in an intellectually honest way. In others, these arrogant doctors will acknowledge PFS but they arrogantly deceive themselves into thinking that they can treat it despite there being no public evidence that patients have had any success.
It’s just a reality of the situation. We have to be open minded bc otherwise nobody will have any success but not gullible. These doctors aren’t actively malicious people but they can be arrogant which can cause harm to their patients.
