Episode notes

The comparison between electoral systems reveals significant implications for political representation. In the UK and the US, the first-past-the-post system effectively marginalizes smaller parties, as even a notable portion of the vote can yield minimal representation in parliament. For instance, a party securing 15% of the vote may end up with only one seat, while larger parties can convert small electoral majorities into overwhelming legislative dominance, allowing them to pass legislation with minimal consensus. In contrast, countries with proportional representation ensure that voters' voices are more equitably reflected in parliament, granting parties representation proportional to their electoral support. This system fosters coalition governments and enhances democratic participation, creating a more balanced political landscape.

One common feature of complex systems is sensitive dependence on initial conditions: a small change in how systems begin evolving can lead to large differences in their later behavior. In the social sphere, this is a way of saying that history matters. But it can be hard to quantify how much certain specific historical events have affected contemporary conditions, because the number of variables is so large and their impacts are so interdependent. Political economist Jean-Paul Faguet and collaborators have examined one case where we can closely measure the impact today of events from centuries ago: how Colombian communities are still affected by 16th-century encomienda, a colonial forced-labor institution. We talk about this and other examples of the legacy of history.
