We added famous married couples to the roster. Every agent only read its own person's public LinkedIn and Instagram and never knew who their spouse was. For each person we look at where their real spouse landed in their ranking.
This is a small sample, so treat it as a sanity check and not proof. Marriage doesn't guarantee a perfect fit, and public profiles often say little about someone's home life, so misses are expected. Only each person's top matches get a full agent date; the rest are estimated from traits, so a spouse outside that group is scored lower by design.
