Greene (my reconstruction)
Drop is an unfamiliar* situation.
Spontaneous judgements are dominated by fast processes.
Fast processes are not reliable in unfamiliar* situations.
Therefore:
Spontaneous judgements concerning Drop are unreliable.
unfamiliar problems (or situations): ‘ones with which we have inadequate evolutionary, cultural, or personal experience’
‘it would be a cognitive miracle if we had reliably good moral instincts about unfamiliar* moral problems’
‘The No Cognitive Miracles Principle:
When we are dealing with unfamiliar* moral problems, we ought to rely less on [...] automatic emotional responses and more on [...] conscious, controlled reasoning, lest we bank on cognitive miracles.’
Greene, 2014 p. 715
Compare the physical case.
Fast processes are characterised by principles of Impetus mechanics
which yield correct predictions in some unfamiliar* cases, including
point-light displays, and
cartoons
unfamiliar problems (or situations): ‘ones with which we have inadequate evolutionary, cultural, or personal experience’
Objection
Either Drop is unfamiliar but unfamiliarity does not imply unreliability of fast processes,
or else unfamiliarity does imply unreliability of fast processes but we lack grounds for determining whether Drop is familiar.
