A dissent at the Federal Reserve is a recorded preference. The statement names the voter and the action they preferred, when there is a dissent. That is the fact. The atmosphere people add — a crack in the institution, a signal of the next meeting — is commentary.
I think commentary is fine in an opinion column and dangerous in a news lede. A 10–2 vote is not a 12–0 vote. Say so, because the statement says so. Do not then write the next meeting. The dissenters have told you what they wanted this time. They have not signed the following statement.
