Differential construal and the false consensus effect.

People's own beliefs, values, and habits tend to bias their perceptions of how widely they are shared. The present research examined whether this "false consensus effect" is partly due to people's failure to recognize that their choices are not solely a function of the "objective" response alternatives, but of their subjective construal of those alternatives. Study 1 provided initial support for the importance of differential construal in people's consensus estimates by showing that larger false consensus effects tend to be obtained on items that permit the most latitude for subjective construal. Study 2 replicated this effect experimentally by asking Ss either a general or specific version of the same question. Larger false consensus effects were obtained on the general version that offered more latitude for construal. Studies 3 & 4 provided further support by showing that (a) Ss who made different choices tended to interpret the response alternatives in ways that reflected the choices they made and (b) subjects who were led to construe the alternatives in the same way tended to make the same choices.
