Have you ever quickly thrown a survey together and then ended up with data that was unusable?
It's because creating a quality instrument takes time. Taking your survey through these phases of pilot testing ahead of time, will result in better data.

Just saw your report on CNN. Please don’t be afraid to say the SC outbreak started in a private school w/ 17% vax coverage, and it is that low largely bc of religious and exemptions. It’s a problem that needs to be acknowledged.

As far as I can tell most people who leave academia but still work in public health are doing relatively simple descriptive work for policy purposes. However, it generally lacks the novelty to get in high impact journals, and in Scotland, NHS workers don't have time to publish.

*Determinant* is a synonym for cause.
But it seems implausible for your voting behaviour to cause your mortality risk (beyond large scale macro changes to the government in control).
More likely it's a complex multidimensional marker of your overall circumstances which in turn predicts your risk.

For 248 years the streets of America didn’t feature a roving masked federal kidnapping squad that might send you a Central American death camp or just murder you themselves, but getting rid of it now is some impossible lefty fantasy that professional Democrats lamentably must struggle against.
Classic Democratic no-win. All of them voted against the OBAA, which supercharged ICE funding and hiring. But they won't say they'd "abolish ICE" so they'll get yelled at (mostly by people who'll vote for them in the midterms after threatening not to).
Top Democrats decline to say if they would rein in ICE after Minnesota shooting

A proper oral exam is not a series of questions that a student is asked to answer. It's a conversation, wherein student and examiner(s) work toward constructive progress on a broader question or problem.
I've spent a lot of time with LLMs and none is close to what a good committee does in person.
