Indoctrination, much like social engineering, is the process by which a population's thoughts and opinions can be forcibly altered. While processes of social engineering typically take a more subtle approach, indoctrination is the more heavy handed route and offers far less deniability in exchange for quicker results. More often than not, indoctrination involves the use of a chemical/pharmaceutical element which the population is forcibly exposed to in order to make them more obedient or perhaps make their minds more malleable. Given the gross breach of what most nations consider to be the basic rights of all sentient organics that this process presents, it is an act that the galactic community does not look kindly upon.
