Criticisms of Freedom in the World during the 1980s were discussed by Gastil (1990), who stated that "generally such criticism is based on opinions about Freedom House rather than detailed examination of survey ratings", a conclusion disputed by Giannone.[21] The definition of Freedom in Gastil (1982) and Freedom House (1990) emphasized liberties rather than the exercise of freedom, according to Adam Przeworski, who gave the following example: In the United States, citizens are free to form political parties and to vote, yet even in presidential elections only half of U.S. "citizens" vote; in the U.S., "the same two parties speak in a commercially sponsored unison", wrote Przeworski (2003, p. 277).[6]
