Oops. Ooooooooooooops.

I do hope that nobody has been given or denied a job/promotion based on their SpringerNature citation counts in the past 15 years.

And to be blunt, a medic and an information systems expert is not a complete and sufficient set of experts needed for this kind of thing to work.

But that step is almost always skipped. So money was spent, timelines can't be met, and the hope is that someone with the needed expertise will rescue the effort after the fact.

This seems to describe at least a few "innovation" projects in the HSE.

And important people want the answers NOW. This has to be done NOW. But it can't be.

The solution of course would have been to consult with an expert at the start who would know how these data will need to be analyzed to meet the aims of the project, and how to format the data to facilitate this.

A hospital has implementation a digital health project. They want to evaluate whether the new digital system is less error prone than the old manual entry based system. They have collected data on the relative accuracy, but in such a borked format it will take ages to make sense of it.

And like most scam victims, the politicians and voters that fell for this one only want to forget it ever happened.

No industry is perfect. But the imbalance is hard to miss. One sector must prove its products are safe & effective. The other profits by avoiding that responsibility. If we care about transparency and accountability, scrutiny shouldnโ€™t be one-sided. (Source: For The Greater Glory of Science) #EpiSky

I've never been a fan of group work as a teacher or learner, but now I feel it's even trickier to manage as people have different interest in use of genAI to do assignments. It's a whole other thing that should in principle be negotiated, but how to manage this practically, and at what cost?

AIโ€™s Modest Productivity Boost 3 years into widespread adoption, AI has delivered a ~0.4% productivity growth bump, putting it on pace with PC-scale lift at best (in ~1/2 the time) rather than radically reshaping the macroeconomy.

Just the blurb from this week's blog app piece penciling out the AI impact on productivity generated a robust discussion, so figured I'd make it my freebie of the week:

Working Paper 33027
DOI 10.3386/w33027
Issue Date October 2024
An unsettling stylized fact is that decorated early childhood education programs improve cognitive skills in the short-term, but lose their efficacy after a few years. We implement a field experiment with two stages of randomization to explore the underpinnings of the fade-out effect. We first randomly assign preschool access to children, and then partner with the local school district to randomly assign the same children to classmates throughout elementary school. We find that the fade-out effect is critically-linked to the share of classroom peers assigned to preschool accessโ€”with enough treated peers the classic fade-out effect is muted. Our results highlight a paradoxical insight: while the fade-out effect has been viewed as a devastating critique of early childhood programs, our results highlight that fade-out is a key rationale for providing early education to all children. This is because human capital accumulation is inherently a social activity, leading early education programs to deliver their largest benefits at scale when everyone receives such programs.

Fair point. The effect of removing coffee from coffee drinkers is plausibly different from getting people to start drinking coffee.

So there you have it, twin study estimates were greatly inflated, and molecular data sets the record straight. I walk through possible counter-arguments, but ultimately the uncomfortable truth is that genes contribute to traits much less than we always thought.

And this isn't dramatics. Elon literally used his power to gain access and destroy USAID which has surely resulted in many many preventable deaths.
