ABSTRACT:
Method and apparatus are disclosed for determining the extent of mutuality as between partners in respect to a given question involving a form of multiple choice answer. The partners initially consider the question and multiple choice answer selection. The partners then, privately and in turn, record their answer on a comparator instrument. The instrument is then actuated to invoke a signal indicating the extent of mutuality with respect to the question. The apparatus is a calculator-type instrument having memory storage capacity for sequentially receiving the answer from the respective partners. Upon actuation, the instrument compares the answers and invokes the signal indication.
