I do biomedical research to help people. When people come in this space making things up, it makes it harder for people not in the field to trust the extensive studies that we do and distinguish fact from fiction. Baseless claims reduce future cures. Willful ignorance drives us backwards.

Talking to Congressional staff is a great way for scientists to inform Congress about the impact of science in their state and the nation. We just had a superb meeting with Abigail Lancaster of NC Senator Budd's office. She was knowledgeable and emphasized their support for science funding 1/2

Surgeon Generals’ Warning: Secretary Kennedy has rejected science, misled the public and compromised the health of Americans. The nation deserves a health and human services secretary who is committed to scientific integrity and can restore morale and trust in our public health agencies.

So the American taxpayer eats it twice, once on tariffs and again on a second farm bailout. I’m glad farmers are getting help, no one should lose their farm, but it’s remarkable how fast “socialism” stops being a dirty word when the checks clear in red counties.
