In 1948, George Gallup learned the tough lesson that political polling was not infallible when he inaccurately predicted that Thomas Dewey would defeat Harry Truman in the presidential election. This mistake led to a reevaluation of polling methods to improve accuracy.
George Gallup is often considered the father of modern polling. He is credited with developing scientific polling methods that are still widely used today, such as random sampling and question wording. Gallup's work in the 1930s helped popularize the use of polls to measure public opinion.
Gallup's four principles of accurate polling are: random sampling, weighting, reducing nonresponse bias, and striving for transparency. By adhering to these principles, Gallup aims to ensure that their polls provide reliable and meaningful data for analysis and decision-making.
