wittyreference··on Why are fewer young adults having casual sex?
If they find no relationship between changing economic circumstances and the outcome, and but a positive relationship between likelihood of co-residence with parents and the outcome, the likelihood that they have made statistical blunders greatly outweighs the likelihood that changing economic circumstances do not play a role.
wittyreference··on Publisher Nacon Cracked and Pirated Our Game: The Sinking City
Because the publisher didn’t pay them agreed-upon sums, and they’re withholding the game awaiting said payment.

I don’t know which parts are true or false, but that’s right in the post, and makes complete sense.

wittyreference··on Amazon Sends ‘Vote No’ Instructions to Unionizing Employees
39 hours + "you come running when we call or you lose it."

It's just shy of full-time (to withhold benefits), but not exactly the same thing as a side gig. And you're bent over a barrel.

wittyreference··on Falling sperm counts, declining egg quality, and endocrine disruptors
> Here's one of many if you google. https://natural-fertility-info.com/study-wi-fi-laptop-comput...

So, a quick rebuttal to this trash blog post recounting a trash publication. This is a cut-and-paste from a real rebuttal (Dore & Chignol, Fertility & Sterility, 2012), transcribed here for easy browsing. Link at the end:

"We think that the evidence presented in this article cannot support the claim that the observed effects are non-thermal and caused by exposure to a Wi-Fi radiofrequency electromagnetic field."

1. Keeping constant the temperature under the computer by an air conditioning system is not sufficient to ensure homo-geneity of the temperatures within the experimental area, be-cause the heat source from the laptop is not homogenous itself, and to exclude that there is no local variation in the samples temperatures. If the exposure design can be justified by the desire of being as close as possible to the actual conditions of use of a lap-top computer, the dosimetry used in these experiments is much too simplistic. There is no indication of the homogeneity of the field under the laptop, which may greatly depend upon the location of the Wi-Fi antenna within the computer.

2. The control samples,‘‘kept in another room away fromany computers or electronic devices,’’were not actually keptunder identical conditions. A more suitable experimental de-sign would have been a sham exposure design in which con-trol samples would have been exposed under the sameactively working computer, but with its Wi-Fi emission turned off.

3. Moreover, Avendano et al. state that‘‘[radiofrequency electromagnetic waves] from mobile phones may cause DNA damage’’and that‘‘research has shown negative consequences of electromagnetic fields on biological mechanisms,’’and they cite in support of their contention a highly controversial article(cite2). Genotoxicity of radiofrequencies is not a matter of opinion: radiofrequency energy absorption cannot break DNA molecules, and it should be kept in mind that there is no known biologically plausible mechanism by which non-ionizing radio waves of low energy can disrupt DNA(cite3). Recently, while classifying radiofrequency electromagneticfields (RF-EMF) as‘‘possibly carcinogenic to humans’’(group2B), the International Agency for Research on Cancer Working Group reached the overall conclusion that there is only weak mechanistic evidence relevant to RF-EMF–induced cancer in humans(cite4)

The conclusion of the rebuttal: "There is a serious message behind our rebuttal. Citing Avendano et al.(cite1) among the evidence of an association between Wi-Fi exposure and a genotoxic effect on humans perm would demonstrate how studies with an erroneous methodology can be used to support important public health claims and also the weakness of the evidence purporting to demonstrate a non thermal effect of Wi-Fi RF."

wittyreference··on Opinion: We’ll Have Herd Immunity by April
In the situation where the argument being put forward relies on the explicitly or implicitly stated expertise of the orator - such as an article which says "Take heed of my opinion of the important medical factors here, for I am a doctor" - contending that said orator doesn't have that expertise is entirely valid, and not ad hominem. Ad hominem is such when the attack on the orator is orthogonal to their argument.
wittyreference··on Living Like It's 99: No Social Media, No Smartphone
That's the height of obnoxious. I can't really imagine the level of self-centeredness required to think that's okay.
wittyreference··on Living Like It's 99: No Social Media, No Smartphone
It's a common thing. Perhaps not where you are.
wittyreference··on Phthalates damage babies' brains and must be banned immediately, say experts
A couple.

Some basic neuro papers have found that it's directly neurotoxic.

Others have found that it exacerbates the neurotoxicity of certain other compounds (e.g., lead).

And other studies have found that pthalate exposure increases urinary output of quinolinic acid, a neurotoxic metabolite of the tryptophan metabolic pathway to which pthalates are structurally similar.

This suggests a couple of things: (1) that pthalates are neurotoxic via the excitotoxic pathway that quinolinic acid acts through, and (2) that pthalates induce higher quinolinic acid production (we've confirmed this is true in humans).

Essentially, we've confirmed pthalates to be neurologically harmful in a number of animal studies, found a candidate pathway, and confirmed that that pathway is in fact affected in the prediction direction in humans experimentally exposed to higher doses of pthalates.

(That last bit slipped by the ethics boards because there are meds that already include pthalates, so patients were randomized to get higher- or lower- pthalate containing formulations of the med, which were otherwise equivalently dosed.)

It's a pretty reasonable conclusion at this point, if one isn't already wedded to the idea of the compound's safety.

wittyreference··on Phthalates damage babies' brains and must be banned immediately, say experts
We've been collecting increasingly reliable data on the harmful effects of pthalates on human development for at least two decades. How much data must accrue, and how harmful must it be, for an immediate ban to not be alarmist?
wittyreference··on Phthalates damage babies' brains and must be banned immediately, say experts
There are multiple variables in play at one time. Like, ... every other thing in medical science and public health. It would probably be more helpful if someone went ahead and just looked closer at the activity of the compound of interest, and saw what impact it had in isolation.

We could call these people researchers, in honor of their tenacity in scrutinizing and re-scrutinizing their work and the work of others. And when their work impacts the health of the many, maybe we could use mass communications technology to share it.

Pie in the sky, I know.

wittyreference··on Scientists Achieve Real-Time Communication with Lucid Dreamers in Breakthrough
> 36 participants > 18% > “many” people reported

Let’s not overstate the findings here.

wittyreference··on Scientists Achieve Real-Time Communication with Lucid Dreamers in Breakthrough
The latter was a debate about materialism, and whether the divine had any physical component (in which case there was a finite number of angels on a pin), or did not (and therefore infinite), with consequences for the debates about whether divinity is a falsifiable hypothesis.

Intelligent people were having intelligent debates.

wittyreference··on I am a heroin user. I do not have a drug problem
dFosB also accumulates in chronic pain and in some types of acute and inflammatory pain.

The grand-parent comment to which I am replying describes near-instant addiction in the context of an opioid prescribed for pain control.

wittyreference··on If all of current free Google services required a fee to use, would you pay?
I've attempted purchasing paid-for alternatives to all of the Google services, and so far they haven't stuck. But yeah, if I could get the advantages implied in being a paying customer (privacy, customer support, UI updates that aren't geared towards their ad business), I would.
wittyreference··on I am a heroin user. I do not have a drug problem
As a physician:

No, the 'vast majority' do not. I've supervised medical grade opioid administration to more than a few people, both acutely and chronically, and *folks without a pre-existing substance use problem* do not often develop one, especially if it's over the short term. The idea that "I give you an opioid and then BAM I want more!" is highly divergent from my clinical experience.

wittyreference··on I am a heroin user. I do not have a drug problem
"Opioids are insanely and ~~instantly~~ quickly addictive."

Do you have a source for this assertion? I'm just a physician with a particular specialty in medically managed (as opposed to procedurally managed) pain, and I've never seen a "I took it once and was instantly addicted." I don't mean to undercut your subjective experience, but I've seen a few folks on pain killers, and if what you described was more common than "very rare", I would have by now.

Ever taken codeine again? You may have a genetic variant of CYP2d6 that makes codeine, in particular, hit you hard. It's not an effect common across opioids.
wittyreference··on Israeli study finds 94% drop in symptomatic Covid-19 cases with Pfizer vaccine
That was an interesting graphic, so I decided to revisit the Israeli graph on EuroMOMO.

The delay in registration is for deaths that occur up until the week-end update; it is a one-week retrospective potential bump. The fall to baseline in Israel began three weeks ago, and has shown a continuous and steady slope.

You spoke too late, and I hope you issue a correction.

wittyreference··on Israeli study finds 94% drop in symptomatic Covid-19 cases with Pfizer vaccine
Israel's issue has been and continues to be a very large orthodox and ultra-orthodox community which has flouted all quarantine laws and appeals to vaccination, in a tiny dense country where said orthodox and ultra-orthodox can't be meaningfully avoided.

That said, their statistics regarding the symptomatic case rate speak for themselves.

wittyreference··on Israeli study finds 94% drop in symptomatic Covid-19 cases with Pfizer vaccine
That was a helpful link!

Your comment is surprisingly true! And utterly out of context.

As of today, Israel's deaths - both for the 65-and-overs and all-ages - is nearly down to its historical normal range, per your link.

Going back two weeks there was a huge peak at a z-score of 9.7; and going back eight weeks it was at a statistically anomalous low, at a z-score of -2.2.

I'd be tempted to point out the period of the low was the high holidays; the enormous deflection to positive slope started a week after the high holidays, and continued for three weeks. So, you know, "a bunch of people broke all quarantine for the high holidays and new year and did their level best to stay home rather than go to the doctor, and caused a giant spike, which has receded as the cases associated with that spike calmed down."

wittyreference··on McKinsey to pay $573M to settle claims over opioid crisis role: source
People say that like the "debt" doesn't ultimately matter - as if adopting a policy of "you only get property ownership rights if you can prove you're sorrier than the person who claimed your stuff" won't lead to calamity over the medium-long term.
wittyreference··on Stepping Down as CEO of the Wikimedia Foundation
I have a hard time imagining something more destructive to the ability to run an organization than putting forward all managerial initiatives for public consent, just in case some portion of the public disagrees with that choice. Talk about design by committee.
wittyreference··on McKinsey to pay $573M to settle claims over opioid crisis role: source
What? Lawyers are absolutely liable. Their only shield is in the most complex realms where the actual legal theory isn't yet tested in court / with a regulator, so you know going in their advice may not pan out, because it's /experimental/.

That's not the vast majority of law, though.

wittyreference··on Moderna vaccine appears to work against variants
Viruses are believed to become less deadly over time when being less deadly offers an evolutionary advantage in ability to spread. If being more deadly and more spreadable have the same mechanism (e.g., avoiding spike protein-inhibiting antibodies), you can expect that old adage not to hold true over the short-term.
wittyreference··on SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma
Oh, it is. I meant that that is also part of 'natural' immunization. The distinction between the 'natural' exposure and the vaccine is that the natural exposure targets a number of epitopes, which may or may not include effective neutralizing antibodies against the spike protein; the vaccine, on the other hand, only offers the spike as an antigen, so you know you're generating neutralizing ab.
wittyreference··on SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma
The primary benefit of the vaccine over 'natural' immunity (other than avoiding actual exposure) is the emphasis on neutralizing antibody formation.
wittyreference··on Patient Regains Sight Following Artificial Cornea Implantation
Most medical stuff comes as kits. In no small part because each individual manufacturer tends to have their own process for the details - it's not as interchangeable as you'd think. In part I think it's a liability thing.

It also helps a lot with sterility.

wittyreference··on Why cancer cells waste so much energy
It's probably not meaningfully higher - this discovery was made a long time ago, and since then we've had a lot of research into which tumors it's really relevant to, and those tumors now get anti-inflammatory medication as a standard part of treatment to prevent just that from happening.

The staging is just ("just") a reflection of the primary cancer mass, which is really predictive of outcomes. It's generally not directly related to whether these sorts of satellite tumors form, since the above advances. It's mostly at this point a historical point of "this is part of how we figured out how cancer works," and ties into the rationale for some of the now-standard treatments.
