An actual hot take: Too many authors are afraid of editors watering down their voice or whatever and not afraid enough of editors letting you put any old slop on the page.

An additional delightful bit -- Dr. Sakaguchi was the only one of the three who got the news directly from the Nobel committee. Dr. Brunkow saw someone was phoning from Sweden and thought it was spam/spoofing (an AP photographer later told her), and Dr. Ramsdell is hiking in a remote part of Idaho.

“Good scientists…know the cure for their ignorance is to actively & rigorously test their own assertions. That kind of humility is no different from enduring the hardships required to become a champion…boxer, a great rock climber or a master musician.

It’s time to make that connection explicit.”🧪🛟

“Good scientists are intimate with the limits of what they know and stand ready to learn in domains outside their expertise. They don't just claim they are right. Instead, they know the cure for their ignorance is to actively and rigorously test their own assertions. That kind of humility is no different from enduring the hardships required to become a champion middleweight boxer, a great rock climber or a master musician.

It's time to make that connection explicit, and the best place to start is with members of Gen Z themselves. If I could talk to that young man on the plane again, I would not simply tell him to exercise caution when it comes to fringe experts. I would instead explain the long traditions of scientific discipline and determination that built the jet he's flying in. Einstein's relativity, evolution and genetics, climate physics on any planet (even alien ones) - these topics are a thousand times more compelling than faked moon landings because they are not the fever-dreams of hucksters but a direct vision of nature's outrageous beauty and complexity. Make the effort to walk down that road, embrace its honesty and humility and you'll be hooked forever.”

Also:
It’s fewer shots
It’s fewer visits to the doctor
Immunization rates go up

So there’s both a social science & a biological science side to it!
