In addition, since happiness correlates to serotonin and other neuromodulator
hormone levels, it can be measured scientifically. Other emotions correspond
to brain activity in specific regions. For example, love is coincident with
activity in the anterior cingulate cortex, middle insula, putamen, and caudate
nucleus. Consequently science can determine if one is in love by measuring the
intensity of activity in these regions.

I think that explains the process sufficiently to give credit to science in
your example. Also, aesthetic values can be quantified and measured
computationally, given the elements which comprise such values as beauty and
attractiveness (as these values derive from symetry and balance, etc.).

In further support of your comments, I'd add that since intelligence impels
scientific methodology, intelligence may also decide when such methodology is
not necessary to solve lesser problems.

Even if the underlying reality is uncertain or subjective, that does not
prevent science providing an objective analysis linked to a grid of known
facts. Scientific methods can fill in knowledge gaps by testing overall
systems. Once a correlation is established, it can be tested to see if
exceptions occur, which would falsify the answer under consideration. So,
science beats every alternative methodology because only science can
ultimately verify solutions derived by intuitive or serendipitous methods.

Nothing beats science...
What a great slogan! Would make a nice bumper sticker.

We move into a better future in proportion as science displaces superstition.
