Answer:
The correct answer is D. All of the above are reasons why researchers use the scientific method.
Step-by-step explanation:
The scientific method follows specific guidelines and a path in order to reach a conclusion. Even though the path may vary from study to study, it has a main core on how to carry it out.
Let's break down each option:
- As stated, human intuition is not enough to determine universal truths, specially about human behavior, since it is not a 100% reliable source.
- Since not all studies follow the same pattern, new knowledge might come up that was not even taken into account earlier. Thus, new discoveries may be added to the existing empirical knowledge.
- As it is a scientific procedure, it takes an objective point of view rather than a subjective one.
In conclusion, all of the options are reasons why researchers have relied on this method during studies about the human behavior.
