For example, a recent tweet from the Family Research Council, an Evangelical lobbying group opposed to abortion and LGBT rights, said that “Abortion is never medically necessary to save the life of a mother,” an assertion
rejected by the American College of Obstetricians and Gynecologists.
The same day the abortion tweet was posted, a Community Notes volunteer added a clarifying note, which then was judged by the other volunteers. Twitter’s system used votes from 169 users, filtering out some ratings that were deemed to be “low quality” using a complex ranking system. Ultimately, 164 of the 169 votes, or 97%, found the note “helpful,” but it wasn’t enough.
