I argue against the widely held liberal view that we have all of the freedom that we could want if we are able to effectively exercise our autonomous choice. I contend that spontaneous freedom is a further sort of politically worthwhile freedom that we might lack even when we can effectively exercise our autonomous choice. When the choices that we make are predictable to other agents who can shape our choice-making environments, our ability to experience spontaneous freedom is threatened. This conclusion suggests that “big data” that enables corporations or governments to accurately predict the behavior of consumers or citizens can threaten our freedom, even when it does not prevent us from freely choosing.
