The Evolution of Polling Methods
Polling has undergone significant changes since its inception in the 1930s, adapting to advancements in communication technology. Initially, pollsters conducted surveys face-to-face, but a shift toward telephone interviews marked a new era, which eventually transitioned to online methods. Nowadays, pollsters primarily recruit participants through online panels, as accessing individuals directly has become more challenging, leading to potential biases in surveys. This evolution highlights the difficulties pollsters face in obtaining a representative sample, as fewer people are willing to participate in polls, complicating the accuracy of the results.
