Engagement-based #algorithms amplify intergroup hostility + moral-emotional content, leading it to be overrepresented in your feed

This leads us to falsely perceive that people want to see this kind of content and share more of it.

“Vaccines contain dangerous and toxic ingredients.”
This one never dies, so let’s tackle it properly. Yes, vaccines contain multiple components but context, chemistry, and dose matter. Vaccine ingredients have been studied for decades, across trials and billions of doses. A 🧵

It’s sad that we’re now having to warn people to be so discerning about what they will hear from the current US government on vaccines. My comments for DW News after the ACIP meeting last week in their article on the recent Tylenol announcement from Trump www.dw.com/en/us-vaccin...

Hopefully the feelpinions about MMR won't become policy but you never know right now. If it became a separate vaccine recommendation, vaccine supply would be a massive issue. Separate visits would lower coverage and delay protection. MMR is carefully timed. It would be a disaster for child health.

Ironically, am in Papua New Guinea doing a workshop on vaccine communication. This morsel provides a teachable moment on what misinformation/disinformation looks like.

When your anti-vax Health Secretary stacks the vaccine committee: "Some members seemed confused about the data they were being presented. After their vote on the program that provides free vaccines for children, some members asked what they just voted on." wapo.st/3K9OBNV
CDC advisers make their first childhood vaccine edit
They voted 8-3 to recommend delaying the use of a measles, mumps, rubella and chicken pox vaccine that about 15 percent of children receive.

Listening to the end of the ACIP meeting, some members lacked knowledge on how their recommendations affected insurance for children. One motion was only drafted last night and members were confused by its meaning, requesting clarification during the vote. Chaos.
