there are filters and there are filters

filters can simply force a model to simulate "reality "
think early weather models
though founded on physical principles
left in the raw outputed
nonsense
the filters were just that
one ought to look at NK sticky as really
just artificial filters
not simplified stick figure represntations

or
filters can torture the data force out false confessions
 and teach perverse class based  agit prop as if its discovered systemic verities
