At AGBTGM26, she’ll explore how moral beliefs shape science, and how transcending the “moral vs. biological” divide can open new paths for discovery.

Comments on this article show how evidence of biology’s role in a behavior doesn’t *erase* moral beliefs about that behavior, but rather interacts w/ moral beliefs in complicated ways

These articles revlea people's uniquely twisted/nasty views about weight & health. Have been reading an early copy @kph3k.bsky.social book on the "genetics of sin" (order it!), & I am convinved we need to confront people's gut instincts about health, it matters and is weaponised (see vaccines).

I wonder about these questions a lot! I can also see a very logical extension to GLP-1s - as a fat person who is not interested in those medications, I’m starting to see subtle shifts from pity to confusion about my size (if she has money and health care, why ISN’T she on a GLP-1?).

Thank you for sharing this insight -- yes, clear parallels with the tensions I describe in this piece but I hadn't thought of the GLP-1 connection!

"Their very public embrace of cosmetic surgery and embryo selection could be seen as a bit of embodied rhetoric in support of their political and economic project. How else to justify...such parasitic hoarding of wealth without advertising yourself as exempt from the shared human condition?"

This is possible! but at this point in my life I am suspicious of any intended changes that hinge on me becoming more efficient— I see some amount of faffing about as unavoidable & my current overall work capacity as pretty inelastic

5. It is basically impossible to be a writer without being a reader. What have you read recently that made you want to write? If nothing comes to mind, then you might need to start there--resolving to read more--before resolving to write more.

4. If you do really want to spend more time writing, why? I want to write b/c living in my head usually feels like living with an out-of-tune brass band, and writing makes the cacophony stop. Knowing *why* you want to write more will make it easier to let go of other ways you might spend your time.

3b. Do you want to spend more of your one wild and precious life stringing together words to express your ideas? Lots of very successful people do not! They collaborate; they employ research assistants, ghost writers, LLMs. Don't try to "make time for writing" if that isn't your real goal.
