Alright, one last attempt I'll just spell it out for you. The reason personal vibes is not the way to find out the truth about something is that the issues with surveys you mention "sample bias and sample size" are so much worse for any one person's experience. Those who do surveys are aware of these limitations and do their best to counter them in different ways. On the other hand you just lived your life. Your vibes being right once doesn't upend the entire field of statistics. I can try to defend the dumb people idea if you want. Here I'll try to demo for you how to get beyond vibes and defend a thought you had. I'm already aware that those with higher college education tend to vote more liberal but that probably isn't satisfying so let's go with IQ vs. political tendency. First study on google and we get: https://pubmed.ncbi.nlm.nih.gov/39130356/ 
And check it out, social liberalism is associated with higher scores on average. Now to be fair it would depend how many standard deviations you qualify as the marker of "stupid" but the trend is there. As you go through more of the studies you get: https://pmc.ncbi.nlm.nih.gov/articles/PMC9548663/ Which was trying to determine if IQ correlated with economic conservatism because as they mention: "Indeed, empirical evidence supports the view that a link between cognitive abilities and political attitudes exists (e.g., Kanazawa, 2010; Meisenberg, 2015). More specifically, most studies indicate that lower cognitive abilities are linked to the endorsement of conservative political views (for overviews, see Onraet et al., 2015; Van Hiel et al., 2010)." So there you go. Dumb people tend more to vote conservative. |
