I am finding it somewhat hard to believe that in the 1990s fully 20%+ of Scottish and Russian households were millionaires? Going to have to check the SCF on that one

The amendment would simply read: β€œall justices have an x year term limit, currently serving justices are subject to that term limit as abbreviated by their current tenure since appointment.” or something along those lines. There are specific carve outs throughout the constitution like this

A looot of money in education being poured into LLM tools to help teachers modify curriculum to fit their classroom/needs, which sure, is helpful, but that seems like the emblematic case, it’s a helpful productivity boost that needs significant oversight

Does using β€˜by’ count as an β€œexplicit” loop?
by(df, df$g, function(sub) lines(sub$x, sub$y, col = as.factor(sub$g))
Feels less loopy than writing lapply for some reason

I’ve watched Google AI/ChatGPT/Claude hallucinate the sources or be incorrect in terms of what the source actually says. I see companies trying to do this constantly with their chatbot gates to customer support as well, it creates a very poor user experience that prevents people from reaching out

I see this everyday where I work so it’s by no means a student exclusive issue, but what the FAQ page has that LLM’s never will is a 0% error rate. Rearranging a UI, adding semantic search, and making better design choices (which ed-tech works on constantly!) seems a vastly superior solution to me

What’s the benefit of a curated LLM tool over a curated FAQ page in this case?

I think the key issue is the framing - people will give different answers if you present all the caveats we have discussed in this thread. Does media present negative bias? Yes. Does that mean surveys presenting forced misapprehension of data are meaningful? Not really imo

Concerning that the trend has reversed in the last 5 though!

This is infant mortality (dying before 1 year), not child (5-year and below) as was originally posted. That WDI data is quite difficult to dig into source material, but I would reference the latest NVSS reports, infant mortality in the US ⬆️:
www.cdc.gov/nchs/data/nv...

I tried tracking down the source here and was unsuccessful, the CDC official data indicates that in the US it has gone up in the last 5 years which is consistent with other medical data I am aware of: wonder.cdc.gov/controller/s...

Arguable that it is as a result of covid, but upwards trend.

Key word β€œvoters beliefs”, there is no political compass messaging slider that can fix already broken beliefs that aren’t even real, gotta change the topic at that point. Generic dems ran better with swing voters

Genuinely curious about the source here, would love to read it. But I think this illustrates my exact point, she tried to campaign to the right/middle on all of these points and they didn’t believe her! It came off as inauthentic and was hopeless from the start of her candidacy.

Independents who are famously indecisive, difficult to engage en masse, and hold nuanced views that go beyond the right-left distinction?

It was a lot of wasted effort campaigning for republican voted as it stands. Which direction do you suggest she should have gone?

I know it’s nitpicky but gained ground really implies that Trump won a greater following, while that simply isn’t true. The chart should be titled β€œHow democrats lost ground”

Any idea on the source there? Would love to read
