 Similar lessons can be drawn from cases of manipulation, in which agents are influenced through physical or psychological means. Examples of the latter include brainwashing, hypnosis, and duress. One might also include more high-tech examples in which the manipulation occurs via direct control of the victim’s brain. (Such examples are usually science-fiction, but see Krug, Salzman, &amp; Waddell 2015.) The extent to which manipulation involves removing, rather than merely reducing, alternatives depends on the mechanism at work. But insofar as we take such examples to involve the blocking of alternatives, we take them to rule out responsibility as well.
