What is considered a shortcoming of polls?

Answer 1

A key shortcoming of polls is that they can be subject to sampling bias, where the selected population does not accurately represent the larger group, leading to misleading results. Additionally, polls often rely on self-reported data, which can be affected by social desirability bias, causing respondents to answer in a way they believe is more acceptable rather than their true feelings. Furthermore, the timing and phrasing of questions can significantly influence responses, making it challenging to gauge public opinion accurately.
