I'd say that it would need to be more minutely calibrated if the intention were to target and effect a specific person within a desired timeframe, but as a whole the initiative should be fairly effective. Everything is deterministic, including the psyche. Bitumans can accurately assume certain values to be in place based on approximate levels of intelligence and the activities a person chooses to engage in. Like everything there'd be a margin of error to account for but on the whole I think it's a pretty solid foundation.
