That would assume that all research results are in harmony. Unfortunately, that's not the case. Not to mention vast amounts of research that suffer from poor research design and/or interpretation that get accepted as fact. The inherent biases by the researchers, the questions they pose, and how they interpret the results confounds the issue further. Unfortunately, things are not as black and white as they may appear.
If things are still open for opinion/debate, you cannot say people poorly understand something. If someone was to poorly understand something, that is implying there is one right answer.
I'm sorry, but I'm not seeing your logic here. What are you trying to say? That there are no gaps in our knowledge? Or that there is only one right answer?
There is only one right answer
Alright, then let's assume that's true.
Do you believe that there is some research that conflicts other research? Do you believe that there is some research that the results are inconclusive? Do you believe that there is research that is presented as fact despite having flawed designs or interpretations? Do you believe there is some research that fails to demonstrate the desired outcome of the funding group, thus is never published? Do you believe there is research that is passed as fact but has not been able to be reproduced with further studies?
If your answer to any of the above questions is yes, then clearly we do not know it all yet and there is room for some debate as we do not know with 100% certainty what exactly the 'only one right answer' is.
If we assume it's true, there cannot be research that conflicts other research.
I for one think everything I said is true, and that there is no debate. Show me research that shows the contrary, which I don't think you can, and then we can agree that the topic can be debated, even though there is only one right answer, so it's not really a debate, as one guy is right and one guy is wrong, or both are wrong.
Now, if we look at the definition of debate as a noun/
noun
1.
a discussion, as of a public question in an assembly, involving opposing viewpoints: a debate in the Senate on farm price supports.
Debating on something factual cannot happen. That is like saying there can be a debate between someone who says the sky is blue, and another guy who says the sky is yellow.
