    Don’t worry, survey models in competent surveys company are made by peoples competent in statistics.
    The number of people needed to survey is something you can calculate.
    FYI I dont know the reputation of americans survey companies, nor found a survey report, so we can’t really judge this except saying the articles should share the survey report

      I mean, I would hope that a company that exists to survey people would be competent in said field. But as someone who has a diploma in maths, I’ll say that I do think four thousand people simply isn’t enough.
