Mediumship – what is it and what does research say?
Mediumship describes practices in which someone reports receiving information from deceased people or other non-physical sources. It raises questions about memory, perception, expectation and how information claims can be tested under controlled conditions.
What is mediumship?
Mediumship is the practice of people who feel they can share information from someone who has died. This may happen during a conversation, through writing or in a trance-like state. Such an encounter can be deeply meaningful, whatever its explanation.
Researchers look at both what mediums experience and whether their statements can be checked under controlled conditions. They ask whether a reading fits one deceased person better than others and how memory, expectations or subtle cues might shape the result.
What is a medium?
A medium is someone who claims to convey information from deceased people or other non-physical sources. In Spiritualist and other spiritual traditions, a medium is often described as an intermediary between the physical world and a spiritual reality.
A medium may describe personality traits, memories or events said to relate to someone who has died. Such statements can feel deeply meaningful to the person receiving them.
However, experiencing such an ability does not in itself establish the origin of the information scientifically. Researchers therefore distinguish between the experience itself, the accuracy of the statements and possible explanations for the results.
Different forms of mediumship
Mediumship can take several forms. Common examples include:
- Mental mediumship: The medium describes impressions such as thoughts, feelings, mental images or words believed to come from a deceased person.
- Trance mediumship: The medium enters an altered state of consciousness associated in some traditions with spiritual communication.
- Automatic writing: A person produces writing that feels spontaneous or seems to originate from a source other than ordinary conscious thought.
- Physical mediumship: In some traditions, this term refers to alleged physical phenomena, such as sounds or moving objects, attributed to spiritual influence.
These forms differ both in how they are described and in how they can be investigated. Classifying an experience as mediumship does not mean a supernatural explanation has been confirmed.
What does research say?
Some experiments use blinded readings, where the medium receives little or no background information. Other people then rate how well the statements fit. Some studies have reported above-chance results and others have not; differences in methods make comparisons difficult.
Other research explores attention, trance experiences and brain activity. These studies can tell us something about the experience itself, but not where the information comes from. Communication with the deceased has not been established scientifically.
A strong experiment decides in advance what counts as an accurate statement. Otherwise a broad comment may sound more precise once the listener knows who it is supposed to describe. Some tests ask several people to rate the same reading without knowing which person it was meant for.
Researchers also try to answer two important questions: Can a medium provide more correct details about a deceased person than would be expected by chance? And if so, how did the medium obtain that information?
Even if an experiment finds that a medium provides more correct details than would be expected by chance, the origin of the information remains an open question. Such a result does not automatically mean the medium communicated with a deceased person.
Other work explores trance, personal experiences and well-being. Such studies can help us understand mediumship as an experience without deciding whether a spiritual explanation is correct.
Researchers distinguish between a statement that feels meaningful and one that can actually be checked. Saying someone was kind may fit many people. An unusual name or a specific event is easier to test, but only when the medium could not have learned it through ordinary means.
Some experiments ask a recipient to compare several readings and choose the one that fits best. Researchers then calculate how often the right choice would happen by chance. That is more informative than simply asking whether a reading felt impressive.
Research also looks at people who visit mediums while grieving. An encounter may affect how someone copes with loss. That question is different from asking where a medium's information came from. Both can be studied, but they should not be confused.
In 2020, researchers published a meta-analysis bringing together results from 18 experiments on mediumship. They wanted to find out whether mediums could provide accurate information about deceased people without learning it through ordinary means. When the researchers combined the results, the mediums performed better than would be expected by chance. The difference was statistically significant, meaning it was difficult to explain by chance alone. The study offers an interesting reason to keep exploring mediumship. It does not, however, show how mediums obtain their information or whether it really comes from deceased people.

What do the findings show?
Some controlled studies report interesting results worth investigating further. They do not, by themselves, show that information came from a deceased person. An interesting positive test needs careful follow-up using the same safeguards, ideally by independent teams.
What remains uncertain?
Small samples, varying scoring methods and possible unintentional cues make conclusions uncertain. Independent replication is essential. Unintentional cues and differences in scoring can change results. Researchers must also consider how readings are matched with recipients.
Overall assessment
Mediumship is a real experience for many people, but the claim that mediums receive information from the deceased remains unproven. Mediumship can be studied respectfully without assuming an explanation. The available evidence does not establish communication with the deceased.
Frequently asked questions about mediumship
What is the difference between a medium and a psychic?
The term psychic is often used for someone who believes they can perceive information beyond the ordinary senses. A medium is more specifically associated with alleged communication with deceased people or other non-physical sources. Usage varies across traditions.
Is there scientific proof of mediumship?
Some controlled studies have reported results above what researchers expected by chance. However, there is still no generally accepted scientific proof that mediums communicate with deceased people. Positive findings require scrutiny, replication and comparison with alternative explanations.
How do researchers test a medium?
In controlled experiments, a medium may be asked to describe a deceased person without knowing their identity. The statements are then assessed to see whether the description fits the intended person better than others. Blinded protocols help reduce cues and information leakage.
Can mediumship be explained psychologically?
Some experiences and apparent hits may be influenced by expectations, memory, general statements and unconscious cues. This does not mean every individual experience has a simple explanation. Carefully controlled experiments are therefore important when investigating different possibilities.
