<div dir="ltr">Yeah, agreed. Mostly what I'm saying is I'd like us to come up with some model+meaning for these scores first, then use that model to work out how to combine them best.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Sep 14, 2024 at 2:47 PM Toby Pereira <<a href="mailto:tdp201b@yahoo.co.uk">tdp201b@yahoo.co.uk</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:13px"><div></div>
<div dir="ltr">The problem is that we can't objectively determine utilities from the scores. We can only make models that make assumptions. I don't think using total score in the trade-off is necessarily bad a thing because it's something we can easily objectively measure; I just don't think it's correct to call it "utility".</div><div dir="ltr"><br></div><div dir="ltr">Toby</div><div><br></div>

Specifically, I doubt voters' utilities are equal to the sum of scores they assign to each candidate. Unlike in the single-winner case, I'm not sure how we can interpret the ratings voters assign to each candidate. If scores were actually linear and additive, that would imply colored voters care just as much about going from 49% of seats for their party up to 51% as they do about going from 97% to 99%.<div id="m_-7299350621188806498ydp9159bb35yiv7364306502yqtfd05656"><br clear="none"></div></div></div></div><div id="m_-7299350621188806498ydp9159bb35yiv7364306502yqtfd68495">
