<div><div dir="ltr">Now I want to make a separate objection: I don't think "you have to Google some polls" is the main problem of strategic voting at all. It takes me just a few seconds to find the 538 website, and we're all constantly inundated with political news anyways. Chances are you already know if your state is mostly liberal or mostly conservative. And to top it all off, your vote won't be the tie-breaking ballot, so the actual benefits of all this research are tiny (assuming what you care about is who wins the election).<div><br></div><div dir="auto">The major costs of strategy are mostly because of <i>insincere</i> voting, which can easily create false consensus effects. If your system encourages lesser evil voting, you can get stuck in a loop where everyone gives a unanimous favorite a low rank to keep the lesser evil from winning, which makes the best candidate look hopeless and prevents them from fundraising or getting into debates.</div></div></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, May 15, 2024 at 7:56 PM Closed Limelike Curves <<a href="mailto:closed.limelike.curves@gmail.com" target="_blank">closed.limelike.curves@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><span style="color:rgb(80,0,80)">> I can't agree at all.

You have to conduct polls, read the news, check 538, etc. before voting. Better to have a system where you can skip this whole rigamarole and just follow a 0-info strategy.

Thank you for saying that much more succinctly than I did.<br>
<br>
Although I would say that winner quality given honesty also matters :-) <br>
At least to avoid the kind of outcomes that lead people to repeal the <br>
method.<br>
