<p>No, it's not suspicious at all!<p>The paper was posted on the 18th of June. I would guess that means they started writing the first draft in the winter of 2026, if not earlier. 2026 data obviously wouldn't be available then, or even now---we're only in September!<p>In fact, most data products take a few months to compile and distribute. The US will release its Q2 estimate of GDP at the end of September, for example; Statistics Canada is on a pretty similar schedule. Thus, 2025 data might not have been available when they started writing either. It's certainly possible to estimate things on your own, but now you need to show that a) your method of estimating GDP (energy prices, whatever) is valid and b) any effects you see aren't simply due to using different metrics.<p>In short, it just takes a while to do and write up research.</p>

<p>Statistically.<p>You build a model that describes how likely people are to get diagnosed with Alzhimer's as a function of sex: maybe 12 women out of 100 get it, while 8/100 men are diagnosed. You can do the same thing for age: almost nobody is diagnosed before 30, it's very rare before 40, and sadly common (~1 in 10) after 65 years of age. There are all sorts of mathematical tricks to include multiple variables,  account for the fact that you can only be diagnosed once, or that data is "censored" (i.e., missing) at some ages because people have already died.<p>Based on that, you can then ask if the prevalence of Alzheimer's Disease among cab drivers is surprising, given their demographics. For example, if we know that they skew male and younger, we'd expect that number to be a bit lower than a naive estimate of 10%. In fact, we can calculate that number and then see if it's unexpected given the number we actually see. In practice, you'd actually do this by fitting two models: one containing job and one that doesn't, and see which one best describes the data and how, specifically, the job factor affects the outcome.<p>However, how well these adjustments work depends on the quality of your data <i>and</i> your modelling. Your model could be missing important factors or have the wrong structure: (e.g., you assume risk is directly proportional to age, but it actually increases more rapidly as you get older). Your data could have problems too: maybe women are more likely to go to the doctor (and thus get diagnosed), even if the actual prevalence is the same.</p>

<p>Why is that sad?<p>It does feel like it’d be “better” if good behavior came from the company’s intrinsic behavior but laws like this help (re)establish norms that encourage those sorts of actions.<p>Likewise, it’d be better if kids say please and thank you because of a genuine sense of gratitude, rather than just to avoid parental nagging—-but that nagging helps develop appreciation for others’ actions.</p>

<p><i>Some</i> analog devices are "DSP" in a wig, but <i>all</i> digital signal processing is really just a convenience wrapper around analog current flow. A very handy one, admittedly, but one that might not always be worth it.<p>There’s also a lot of path dependency. SHA256 makes a lot of sense once you already have lots of digital data but you’d probably do something else entirely in a more analog world.</p>
