Multi-party systems generally tend to have less of a gap between parties. Especially if no single party is strong enough to hold majority power alone in a parliamentary system, decision-making requires collaboration between multiple parties. A lot of the polarisation in US politics is probably due to the two-party system. I don't know whether or not that has anything to do with people thinking in false dichotomies in other contexts.
