The first-past-the-post system in politics leads to a two-party dominance where individuals have to align their beliefs with either Democrats or Republicans. This binary choice stifles nuance and individuality in political opinions, forcing people to conform to their chosen party's ideologies. The pressure to fit into these bundles discourages critical thinking and fosters groupthink. To break free from this cycle, individuals may need to detach themselves from politics to maintain clarity in their thinking.
