The terms psychic and medium are used by the general population somewhat interchangeably to describe individuals who are intuitive and who use divination practices or communications with other worldly beings. However, there are clear differences between the two terms.
A medium has the ability to communicate with the spirits of the dead. This may be accomplished by channeling, in which the medium acts as a go-between for the other side. While it is believed that all people have some degree of psychic or intuitive ability, mediumship is very rare.
A psychic works at an intuitive level. Individuals who are psychic claim to have the ability to perceive information hidden from the normal senses via a “sixth sense” or extrasensory perception. A psychic may be able to foretell the future in many areas–love, money, career, or travel–by using a variety of tools or spiritual channels.
A medium may have psychic abilities, but a psychic may not be a medium. Some mediums or psychics also claim to be clairvoyant, meaning they can see the spirits of the dead.
Psychics and mediums work in an altered state of awareness. Psychic abilities can be developed, while becoming a medium cannot–it is purported to be a gift an individual is born with.
