Numerous methods have been employed and tests devised for the purpose of measuring interest and interest values. Subjective measures open to the usual errors of personal judgment, prejudice and observation are those requiring an oral or written response. When individuals are questioned about their interests or preferences, they may not know them accurately or be inclined to answer according to what is expected, or find difficulty in expressing what they feel. Testing interests is for the above reasons often cumbersome and unreliable. In addition to the limitations stated above, individuals, when required to make a verbal or written response, often become self-conscious and, as a result, emotions block their decision.
