Generally, people assume that a plurality of marriages that aren't theirs will end.
Their marriage, of course, isn't like those.
We humans are really bad at seeing our biases.

A plurality is the largest individual share where there is no majority. Since marriages have only two outcomes (end by death, end by divorce), there is no room for a plurality, only a majority one way or the other. I don't think people falsely assume other outcomes which reduce the biggest share to a mere plurality.
And there is precious little evidence to support that the biggest share (majority or plurality) is to end in divorce.
