  We analyse the implications of the closure of the physical for experiments in
the scientific study of consciousness when all the details are considered,
especially how measurement results relate to physical events. It turns out that
the closure of the physical has surprising implications that conflict with
scientific practice. These implications point to a fundamental flaw in the
paradigm underlying many experiments conducted to date and pose a challenge to
any research programme that aims to ground a physical functionalist or
identity-based understanding of consciousness on empirical observations.
