Halliday & Matthiessen (2014: 580-1):
It would be possible to recognise causative forms of reality-phase, as follows:
(1) apparent: John seems to be responsible
(caus.) Mary considers John to be responsible
(2) realised: John turns out to be responsible
(caus.) that proves John to be responsible
But consider and prove are better treated as, respectively, mental and verbal processes, with the proposition/process being projected; note the closely agnate finite clauses with that, and cf. it seems/turns out that John is responsible.
Lest this be misunderstood, at clause rank, the causative examples are relational processes with (1) mental assignment and (2) verbal assignment.
