The Matchmaker

A third party takes the wheel, and the algorithm or the aunt drives the plot. The matchmaker trope outsources the meeting, a service, a system, a determined relative, a bet, and generates its story from the gap between the match on paper and the want in practice: the trope's oldest joke, and its oldest wisdom, is that the machinery is usually arguing with the heart, and the heart is usually right about the wrong person.

Two classic circuits share the engine. In one, the assigned match is resisted and then, embarrassingly, correct; in the other, the matchmaker or the control group proves the real answer, science falling for its own placebo. Either way the promise is the same, that compatibility can be measured but choosing cannot, and the couple's yes must finally be theirs rather than the system's. The desk's test is the machinery's fair hearing: the method must be good enough to be worth defying, because a strawman algorithm makes the heart's victory cheap.
