In marketing terms, what is a blind product? A non-profit organization I had solicited, said They would not buy muy guide to free money and resources because it was a blind product.

blind product test is a method of research in which people in a sample are asked to test various products that are not identified by brand name-for example, Brands X, Y, and Z. Products are tested in this manner so that respondents will be more likely to answer questions without bias or partiality toward the product because of its name or reputation, or because of previous experience with it.
