Final answer:
Before the scientific method, doctors used ancient texts, medical traditions, and observations to prescribe remedies for illnesses. One dubious remedy was bloodletting. Cannibalism exists due to cultural/religious traditions, survival scenarios, and psychological disorders.
Step-by-step explanation:
Before the scientific method was used, doctors relied on various sources of information to prescribe remedies for illnesses. These sources included ancient texts and medical traditions passed down through generations. Doctors also observed the symptoms and outcomes of patients to guide their treatments.
One dubious remedy was bloodletting, which involved intentionally making small cuts or punctures in a patient's body to release blood. It was believed that balancing the body's humors (fluids) would restore health. Bloodletting might have appeared to work because some illnesses may resolve naturally over time, giving the impression that the treatment was effective.
Cannibalism exists for various reasons. In some cases, it has been practiced as a cultural or religious tradition. In extreme situations, such as during famines or in survival scenarios, cannibalism may occur as a last resort for obtaining nutrition. Additionally, certain psychological disorders may contribute to cannibalistic behaviors.
