Martin-Quinn scores, or MQ scores, are dynamic metrics used to gauge the ideology of a U.S. Supreme Court Justice based on their voting record. A jurist's score will continuously change as each judicial decision they make creates a new data point to be input into the model. MQ scores theoretically have no minimum or maximum values, but scores generally fall between -5 and 5. A negative number indicates a tendency towards liberalism, while a positive score indicates a tendency towards conservatism.
