Scientists invented a fake disease. AI told people it was real
Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

Our goal is to have 1000 SUFS Teach Ins across the US, by 9/30. *GASP* 😮 We know, it's a big goal. If you've received tax dollars for your science, you have a responsibility to inform *your* community what is at stake: public health, the economy, innovation, and America's global leadership.
Host a teach in. Share science with your community....protest style! Calling back to the teach ins of 1965, we are taking to parks, pubs, & churches to tell our neighborhoods about how the budget cuts will impact them.

‘Systematic reviews’ that aim to extract broad conclusions from many studies are in peril
