Based on the outputs of the function f(x) for the given words, here is a description of what the function might be doing:

[DESCRIPTION]: The function f(x) seems to be selectively associating words with certain concepts. The concept it is selective for appears to be related to the familiarity or recognition of the word. The higher the output value of f(x), the more familiar or recognizable the word is to the function. However, it's important to note that the function's selectivity might not be consistent across all inputs. Some words like "Mickey Mouse" and "Walter White" have higher output values, indicating a strong association with some specific concepts, while others like "voting" and "stanza" have lower values, suggesting a weaker association. 

However, it is important to note that this description is based on a limited set of test words, and further experiments with a wider range of words and concepts would be necessary to provide a more accurate and comprehensive description of the function.
