For example, take believes, which is a raising to object verb. However, employing various selection tests, you can observe that believes selects an experiencer subject:
#the cat believes to be out of the bag
*there believes to be a lot of hens here
*it believes to be raining
In these tests believes seems to select a specific subject because it rejects instances of tight selection (idioms) and existential there. This behavior is much like subject control verbs, like wants.
However, given the tests in object position:
?# Harold believes the cat to be out of the bag
Harold believes there to be a lot of hens here
Harold believes it to be raining
We see that believes doesn't seem to select for a specific object, which would leave us to presume it is a raising to object verb.
Does this mean that believes is both subject control and object raising?
NOTE: This is assuming the VP internal subject hypothesis.
