Final answer:
The provided materials do not offer a specific percentage of respondents who falsely claim to have voted. Voter turnout in the U.S. varies with 55% to 65% in presidential elections and less in non-presidential elections.
Step-by-step explanation:
The question pertains to how often people exaggerate their participation in elections, specifically focusing on the discrepancy between actual voter turnout and self-reported voter rates in surveys.
This phenomenon reflects the social desirability bias, where respondents might claim they voted due to the perceived social expectation to participate in elections, even when they did not. Regarding the actual percentage of respondents who claim to have voted when they did not, the provided text does not directly supply this figure.
However, it highlights that voter turnout in U.S. elections fluctuates significantly, with about 55% to 65% participation in presidential elections and less in off-year and local elections. Furthermore, we understand that mandatory voting laws are in place in some countries, which influences participation rates.
