Another observation about the &quot;Other side&quot; (that is, really, about all of us) to add to excellent points made by others here.<p>Most disagreements happen around things that have no direct impact on day-to-day life. People can hold widely different opinions about politics because... it&#x27;s politics. Most of it is bullshit, and rest doesn&#x27;t affect your daily life anyway, at least not immediately or directly. Take two people who are in fierce disagreement about the balance between government intervention and market freedom - take them, and go see how they manage their personal checkbooks or how they maintain their homes and cars. Suddenly, you&#x27;ll see agreement, similar solutions, and both people being generally smart.<p>People are <i>pragmatic</i>. We tend to invest in knowing the actual truth proportionally to how the issue is actually important to us. Hence most disagreements are about things that actually cost us nothing when we get them wrong.
