that argument is essentially the same as "how do I know what I see as blue is blue to you?"
which is almost entirely moot.
Sure, science will never be able to describe what anger is like for every individual person in each possible context. That is not its goal or scope or even desire. The same way that science will never be able to describe the perception of blue that makes you know what blue is like for everyone. But who cares? Why is that an important question in the first place?
Regardless of what it feels like to be angry to you, there are huge amounts of information we can say, such as what is active, how connected areas may impact your explicit feelings or behaviours, etc. I can't really think of something less interesting than whether your experience of happiness differs from mine, similarly, whether your perception of the wavelengths that comprise blue is the same as mine.
Additionally, this view I feel puts far, FAR, too much emphasis on the conscious experience of things. There are many behaviours that are of trivial difficulty to elicit from people without their conscious knowledge. You can learn, feel, perceive and even do more complex things like problem solve or become motivated using systems whose information processing never becomes conscious in the first place. Conscious experience is, in fact, a secondary epiphenomenon that arises from these systems, often completely unaware of what and why it is doing or experiencing what it is. There is far less information that could arise from studying people's moment to moment conscious experience than studying their neuronal activity compared to explicit research tasks.
