What Is the Most Reliable Measure of Public Opinion?

Polling is said to be the most reliable measure of public opinion due to its precise measurement methods. Polling first started in 1932.

Polls are most commonly used to measure public opinion related to politics, but they can also be used for other matters, such as current events. In order for a poll to be effective, it must include questions that are worded objectively and do not lead the respondent to an answer. The sample of respondents must be random, which can drive up costs. Telephone polls remain the most effective way to poll a large sample size at random because of the ability to randomly dial numbers.
