Abstract
I present three reasons why philosophers of science should be more concerned
about violations of causal faithfulness (CF). In complex evolved systems, mechanisms
for maintaining various equilibrium states are highly likely to violate CF. Even when
such systems do not precisely violate CF, they may nevertheless generate precisely the
same problems for inferring causal structure from probabilistic relationships in data as do
genuine CF-violations. Thus, potential CF-violations are particularly germane to
experimental science when we rely on probabilistic information to uncover the DAG,
rather than already knowing the DAG from which we could predict the right experiments
to ‘catch out’ the hidden causal relationships.
