Re-education is a process of teaching someone new or different attitudes, beliefs, or skills, often after going through a negative experience. There are several synonyms for the term "re-education," including rehabilitation, reconditioning, productivity training, brainwashing, and enlightenment. Rehabilitation usually refers to the process of restoring an injured or ill person's health, while reconditioning is used to describe putting something that has been out of use back into working order. Productivity training and enlightenment are used when referring to improving performance or expanding knowledge in a particular area or discipline. Brainwashing, on the other hand, is often associated with forced or manipulative methods to re-educate individuals to adopt a particular ideology or belief system.
