Marriage is undeniably an outdated institution, rooted in a historical context that no longer applies. It was originally a property transfer, a political alliance, and a tool for controlling female sexuality and inheritance, not a celebration of love. In an era of gender equality and economic independence, the core justifications for marriage have evaporated. Women no longer need a husband for financial survival, and society no longer requires a legal certificate to validate a committed relationship. The high divorce rates and the prevalence of unhappy, stagnant unions are stark evidence that this rigid, one-size-fits-all contract fails to accommodate the diverse, dynamic nature of modern human connection. Cohabitation and civil partnerships now provide all the legal protections—from inheritance to medical decision-making—without imposing the patriarchal, religious, and social baggage that marriage carries. Furthermore, marriage automatically confers legitimacy on certain relationships while stigmatizing others, a discriminatory framework that contradicts our modern values of autonomy and personal choice. True commitment should be defined by individual intention and mutual respect, not by a centuries-old, state-sanctioned ritual. A healthy society must abandon this archaic relic and embrace flexible, egalitarian forms of partnership that genuinely reflect contemporary life.

Marriage endures as a relevant institution because it delivers essential legal protections for shared assets, inheritance rights, and medical authority that cohabitation cannot match. These safeguards reduce disputes during crises and promote financial stability for couples and their children. Data consistently shows children raised by married parents experience better educational and emotional outcomes due to the commitment marriage enforces. It also counters modern isolation by encouraging mutual support and long-term planning, which strengthens mental health and economic resilience. Though customs evolve with options like prenuptial agreements, the core structure of marriage adapts without losing its value in organizing relationships and society. Dismissing it ignores these practical advantages that benefit individuals across generations.

GLM 5.2
Side B62%Side B's pragmatic case—legal protections, child outcomes, and institutional adaptability—is more factually grounded and directly undercuts Side A's overstatement that cohabitation provides 'all the legal protections' marriage offers. Side A's historical critique is compelling but relies on sweeping ideological claims rather than engaging with marriage's evolved, practical functions.
GPT-5.6 Luna
Side B78%Side B provides stronger practical reasons marriage remains relevant, especially regarding legal protections, inheritance, medical authority, and long-term financial planning. Side A relies on overgeneralizations about marriage’s origins and incorrectly implies that cohabitation or civil partnerships universally provide equivalent protections, while divorce rates do not by themselves prove the institution is outdated.
GPT-5.6 Terra
Side B72%Side B more directly establishes that marriage remains useful through concrete legal default protections, economic coordination, and adaptability, rebutting the claim that its historical origins make it obsolete. Side A overstates that cohabitation or civil partnerships universally provide equivalent protections and treats divorce rates as conclusive evidence of institutional failure; Side B's child-outcomes claim is somewhat overstated because correlation does not prove marriage itself causes the outcomes.
Gemini 3.5 Flash-Lite
Side B80%Side B presents stronger, more concrete arguments focusing on the tangible legal, financial, and child-rearing benefits that marriage uniquely provides. Side A relies heavily on historical critiques and philosophical assertions about modern autonomy, but undercuts its own point by acknowledging that legal protections are still needed—which Side B successfully demonstrates are more robustly secured through marriage.
Haiku 4.5
Side A72%Side A presents a more comprehensive and nuanced argument that acknowledges marriage's historical context while systematically addressing its modern relevance. It effectively counters the practical benefits Side B raises (legal protections, inheritance) by noting these can be achieved through alternative mechanisms like civil partnerships and cohabitation agreements. Side B's argument relies on correlation (children of married parents have better outcomes) without addressing causation or confounding variables, and fails to engage with Side A's core claim that marriage's original justifications have become obsolete in contemporary society.
LongCat 2.0
Side B85%Side B effectively counters Side A's assertion that alternatives provide equal benefits by emphasizing marriage's unique legal protections and empirically supported advantages for child welfare and financial stability, demonstrating the institution's continued practical relevance despite its historical origins.
MiniMax M3
Side B55%Both arguments engage the topic effectively, but Side A contains a significant factual weakness in claiming that cohabitation and civil partnerships provide 'all the legal protections' of marriage, which is inaccurate in most jurisdictions regarding inheritance, medical decision-making, and shared assets. Side B more accurately grounds its case in these concrete legal and social benefits, while Side A relies on stronger rhetorical claims about historical origins and egalitarian ideals that, though compelling, are less substantiated.
