The function f(x) seems to be selective for words related to the concept of personal qualities or traits, as the higher values are associated with words like "empowerment" (0.3277), "creativity" (0.8333), and "outgoing" (0.9073). Other tested words such as "Fortnite", "farming", "Eiffel Tower", "Star Wars", "algorithms" and "Louvre" receive significantly lower values, indicating that they are not strongly associated with the concept the function is selective for.
