Quantifying the outcomes of rumors isn't an exact science. For the purpose of this story, we focused on five types of falsifiable rumors: breakups, pregnancies, marriages, engagements, adoptions, and reconciliations. Within each category, we used our own judgment as follows:

To fit into the breakup category, an article or cover needed to explicitly state that a separation or breakup occurred. Official statements and legal separations were used as verification. Reconciliations followed similar rules.

Marriages and engagements said to occur within a week of their verified dates were considered accurate. Any pregnancy prediction within the 9-month gestation period was also deemed accurate. It is possible that a celebrity could get pregnant, then miscarry or abort, a factor we couldn't accommodate for, and a fact of life that celebrity pregnancy speculation generally ignores.
