<p>Ha! I’d never thought about it like that but…yeah.<p>I suspect another big part of it is that marketing and sales are relatively easy to measure <i>and</i> to scale.<p>You can hire one, two, or three new salespeople and expect that revenue will change more or less proportionately. Fixing (or ignoring) a handful issues doesn’t scale so smoothly—-there are jumps where the product suddenly seems much better/worse.</p>

<p>And I’m sure those companies also have “backlogs" due to limited labor/labor costs. There are always shelves to face, vehicles with deferred maintenance, and so on.<p>Obviously, there are limits: I’m not sure what my local grocery store or bus line would do with 100 new workers, but I have no doubt they could put a few people to work right away.</p>

<p>I wouldn't say "called into question", as if the whole idea is bunk.<p>MRI is, in general, a lot harder than people often imagine. It uses complicated physics to measure convoluted physiological changes to indirectly measure brain activity, which is obviously stupifying involved--and then relate that to other, often complicated factors like behavior, lifestyle or disease state.<p>I think it's reasonably well-known that the BOLD response is complex and doesn't directly reflect "average" spiking activity. Some studies find that it's sensitive to the amount of synchrony (=more neurons firing together in time) rather than the rate. The paper you mention shows another dissociation: neurons can get more fuel by extracting oxygen more efficiently OR have having more overall oxygen to extract at the same rate. Thus, it's not noise, but it is complicated.</p>

<p>I'd be surprised if it were possible to <i>directly</i> measure muscle activity with millimetre wave radar. It looks like they're detecting motion, which is <i>related</i> to motor activity, of course.<p>EEG "spellers" c. 2000 required a cooperative participant who's actively engaged in a behavioural task: you attend to the letter/word you want to send and thereby produce a different response when it (vs the other letters) flash.<p>Implanted electrodes can do a lot better but it's still not something that will let someone "slurp" your thoughts out of you -- it'd be like subvocalizing them.</p>

<p>There’s a cute study demonstrating this effect by comparing career success in economics and psychology.<p>The author lists for economics papers are traditionally alphabetized, so more of your output will be known by your name if it occurs early in the alphabet. Abbie Ableson gets lots of mentions as "Ableson et al." while Zhang Zhu will almost always be relegated to the "et al". If name recognition matters, you’d expect successful academic economists to be clustered at the beginning of the alphabet—-and this appears to be true.<p>In most psychology journals, the author list is instead ordered by contribution/senority, and this effect disappears.

<p>Cmon…We’re saying that a certain  style of reference gives her <i>less credit</i> than might be due. Not none at all.<p>One paper doesn’t make a career (she wrote many dozens), it’s not always cited weirdly, and even if it is, some people may remember the coauthors (as they should).<p>But since you mention lived experience, I’ll add that I’ve certainly been asked if I’m "even aware" of results from co-authored papers where my name was listed second—-and I don’t think this is very uncommon experience.</p>

<p>I don’t know that everyone would label it like that, but it’s inarguably true that success in academia comes from your reputation/name recognition.<p>Metrics are often attempts to formalize this but they’re not how most people actually make decisions: nobody is inviting seminar speakers or choosing collaborators <i>because</i> they have a high h-index. If anything, it goes the other way: name recognition gets you invited to speak or collaborate, which makes more people aware of your work, which boosts metrics.</p>

<p>The automated ones don't care, but it absolutely matters for the informal credit assignment process that actually runs academia.<p>I really wish we had a better way to "name" papers. Big clinical trials often have an acronym (often hilariously forced: "CXCessoR4"). That takes the emphasis off (one) lead author  but it's implausibly hard to make up one for every research paper.</p>

<p>You rediscovered normal saline!<p>The plain water hurts because it's causing cells to swell or even burst as water rushes into them to equalize the osmotic pressure. Adding a little bit of salt to that helps remove that pressure because the environment inside and outside of the cells are both equally salt.</p>

<p>Inertia doesn't really seem like it would lead to 300% YoY growth...<p>OTOH, National Lampoon hasn't put out a magazine since 1998 or a film since 2015 (and that was a retrospective on the magazine).<p>I guess I'd agree that, in absolute terms, The Onion might be less of a cultural force than it was in 2005 (say), but part of that has to be that culture is a lot more long-tailed: music, movies, and TV aren't dominated by a handful of works either.</p>

<p>In case people are missing the joke...<p>Willian Proxmire was a Senator from Wisconsin who was <i>strongly</i> opposed to government spending on basic research. He gave out "Golden Fleece" awards for studies that he thought were absurd. Unfortunately, it is very easy to make meaningful research sound ridiculous: bread mold as a cure for STDs? Pencil dust computers?</p>
