The trouble with those concepts is that there’s no way to measure them precisely. This tends to be at odds with the scientific method, though people try to sidestep them. E.g. the noun definition of green is > a color intermediate in the spectrum between yellow and blue, an effect of light with a wavelength between 500 and 570 nanometers; found in nature as the color of most grasses and leaves while growing, of some fruits while ripening, and of the sea. This is different than saying that quarks exist, and that protons are formed from two up quarks and one down quark. These are truths of nature, whereas your examples are of human nature. It’s hard to even say whether a statement about them is true or not, let alone that those things exist.
