Ig Nobels ceremony moves to Europe over security concerns Marc Abraham: β€œDuring the past year, it has become unsafe for our guests to visit the country."

The brain drain continues – the U.S. has lost arguably its most important scientific awards ceremony:

To Jan 20th 2026 there have been 1779 paid ACC claims for vaccine injury from 14 million doses. We know this already. side effects are no surprise, but they are rare. e.g. there were 73 vax site infections. But knowing facts does not publicise "angry bloke in pub's reckons" for ACT & NZF

I can lean on my actual experience to yell at everyone that this won't work! You can't identify emerging customer needs by aggregating data from the past! We tried this already with personas and again with big data! This is like the stupid business version of the problem of induction.

It depends on where in the country exactly you are. I will feel a lot more comfy commenting after the next wastewater update (likely tomorrow) but as of nearly 3 week old info, e.g. I am fairly confident it is post-peak in Wellington/Hutt, at peak a bit further up the coast, so still spreading out.

Admissions, showing last July

Here is the difference in hospital admissions between now (2 weeks ago) & when the death data reporting is for.
Yes, people will be dying now, but very probably fewer than then. Yes, all behaviours still apply if you don't want covid. Yes, a wave raises risk vs non-wave. But data date matters too.

While we might wish politicians wouldn't destroy the social fabric for gain, & might wish media quote the report itself to add context when repeating claims, we can at least invite those we know personally on-spreading claims to read aloud key report statements & judge politicians trustworthiness

Quick graph, GDP growth and crude oil price

speed reading the methodology in appendix D of www.mbie.govt.nz/dmsdocument/..., at first glance I think it may not be capturing that may of the inputs are interconnected (the Middle East), so (while other things were going on at the time too) the 70s/80s suggests it may be worse.

Admissions

Hospital Admissions are at least only 2 or so weeks back (and Wastewater is within 1-3 weeks, with how much within depending on the exact week)

And the covid reporting dashboard has been updated from 19 deaths reported in the (as of now) week before last, to 5 reported last week.
But, to keep shouting at the void, this tells us nothing about the progression of the current wave, as the reporting is now but the events were July last year.

We don't need, and crucially cannot trust, politicians to summarise RC reports and tell us what the findings were. If we could we wouldn't need RCs

We have the report itself and journalists for that summary role.

The news value of pol reaction is simply how honest those reactions are

Excess as best calculated.

Excess as best calculated.

... would go to the more technical approach, but it does look like this- Still low overall, with some individual weeks above average when the annual peak occurs a few weeks later than normal for example. So this is more for good faith readers here.

If I do the full excess mortality calculations to the best of my ability, which is what is happening against a trend estimate, that creates arguments about how you judge the trend. Those can be in good faith with experts, but someone claiming massive increases ain't good faith or expert. So I...

2023: Deaths 33072, Population 1154560, rate 28.64 per 1000
2024: Deaths 32958, Population 1183560, rate 27.85 per 1000
2025: Deaths 32913, Population 1212240, rate 27.15 per 1000
Again decreasing.
This is not fancy maths, but it is easy to see there is no massive increase. And easy to understand.

Not at all. If you only count deaths, it went up, because there are more old people living to naturally die. But if you measure mortality like it’s been measured, the past few centuries, using death rate by age, it is low.
I am out for the evening but can get some graphs and sources later.
