This is from the Washington Post:
Policy analysts at the Centers for Disease Control and Prevention in Atlanta were told of the list of forbidden words at a meeting Thursday with senior CDC officials who oversee the budget, according to an analyst who took part in the 90-minute briefing. The forbidden words are “vulnerable,” “entitlement,” “diversity,” “transgender,” “fetus,” “evidence-based” and “science-based.”
In some instances, the analysts were given alternative phrases. Instead of “science-based” or “evidence-based,” the suggested phrase is “CDC bases its recommendations on science in consideration with community standards and wishes,” the person said. In other cases, no replacement words were immediately offered.
In contrast, this is from USTR's original NAFTA negotiating objectives:
Establish new and enforceable rules to ensure that science-based SPS measures are developed and implemented in a transparent, predictable, and non-discriminatory manner.
It's kind of funny to imagine whoever decided that the CDC should avoid these words going over to USTR and making the same pitch. I don't think it would be very well received.
