Factor into: active or passive?

From BBC News:

The team's campaign director said in a statement that "phony ticket requests never factor into our thinking" as entry to rallies is on a first-come first-served basis.

From what I know, we "factor something into another." So, should it have been, "have/has never been factored into our thinking," instead?

Solution 1:

Not Passive.

Verbs that act this way are quite common. I'm sure there is a technical name but I don't know it. An important requirement is that they have a transitive and an intransitive version. Here are a few examples:

He changed his socks.

He changed after the accident.

The water boiled.

I boiled the water.

The life-raft deflated.

The deckhand deflated the life-raft.

The house burned down.

The arsonist burned the house down.

In business jargon, there is a tendency to use more and more words like this even if they don't traditionally have this form.
