ResumoSUMMARY: A review of the theory and practice of the two‐stage triangle test for the sensory perception of small differences leads to the conclusion that its disadvantages usually outweigh its advantages. When the test is used its information content is difficult to assess; and a “least objectional” method, based on a scoring scheme and statistical significance procedures, is here proposed.
