A Proxy Sitting is a séance in which another person sits in on behalf of the person receiving communication from the spirit world.
Proxy sitting is an attempt by psychical researchers to eliminate the possibility of telepathy during a séance. Typically a third party goes to the sitting in place of the person who desires evidence of spirit communication. This proxy sitter knows nothing about the person he or she represents, nor about the deceased who will be requested to communicate. Thus, although clairvoyance or other ESP phenomena may be in operation, telepathy from the sitter is ruled out as the explanation of any information the medium may give.
