In the attention schema theory, to go about determining whether a machine is conscious, we should probe its innards to find out whether it contains an attention schema, and we should read the information within the attention schema. We will then learn, with objective certainty, whether this is a machine that thinks it has a subjective conscious experience in the same way that we think that we do. If it has the requisite information in that internal model, then yes. If not, then no. All of this is, in principle, measurable and confirmable.
