Large-scale surveys of US attitudes reveal widespread misperceptions that determine economic biases. Stefanie Stantcheva, professor of economics at Harvard University, explains that Americans’ misplaced optimism about social mobility makes them less likely to support tax and spending programs to help the poor. Similarly, Americans overestimate the number of immigrants in the United States and the percentage of immigrants who are poor, breeding a general hostility to immigrants. She finds that di

We saw that if we want to have a probability of at least 95% that the poll results are within 1 percentage point of the truth, Chebyshev's inequality recommends a sample size of n=50,000 . This is very large compared to what is done in practice. Newspaper polls use smaller sample sizes for various reasons. For each of the following, decide whether it is a valid reason. In the real world, a) the accuracy requirements are looser.b) the Chebyshev bound is too conservative. c) the people sampled are
