Given @GavinWilliamson failure to apologise this week for 'last-minute' decisions on schools policy during the pandemic, we thought it might be useful to put to together one handy thread of every U-turn from the @educationgovuk since April last

New from me:
I’m launching my Forecasting For SEO course next month.
It’s everything I’ve learned, tried and tested about SEO forecasting.
The course: https://t.co/bovuIns9OZ
Following along 👇
Why forecasting?
Last year I launched https://t.co/I6osuvrGAK to provide reliable forecasts to SEO teams.
It went crazy.
I also noticed an appetite for learning more about forecasting and reached out on Twitter to gauge interest:
The interest encouraged me to make a start...
I’ve also been inspired by what others are doing: @tom_hirst, @dvassallo and @azarchick 👏👏
And their guts to be build so openly in public.
So here goes it...
In the last 2 years I’ve only written 3 blog posts on my site.
- Probabilistic thinking in SEO
- Rethinking technical SEO audits
- How to deliver better SEO strategies.
I only write when I feel like I’ve got something to say.
With forecasting, I’ve got something to say. 💭
There are mixed feelings about forecasting in the SEO industry.
Uncertainty is everywhere. Algorithm updates impacting rankings, economic challenges impacting demand.
It’s difficult. 😩

Normally I enjoy the high standards of journalism in @guardian . Not today as disappointed with misleading headline that suggest infections are spreading fastest in children. It'll worry parents/teachers & I doubt most readers will unpick the
The latest REACT1 report shows prevalence of infection in ALL age groups has fallen, including children aged 5-12 from 1.59% in Round 8 to 0.86% in Round 9a. The authors of REACT1 report also (wisely) didn't try to interpret the prevalence figures.
If this were a research trial you wouldn't place much weight on the age differences in % prevalence because of the wide confidence intervals, i.e. differences weren't statistically significant.
3/
I've previously tweeted on the challenges (& dangers) of interpreting surveillance data. One would need lots more contextual info to make sense of it & arrive at sound
Undoubtedly some will extrapolate from the prevalence of infection figures in children to other settings i.e. schools based on the headline. I'd advise caution as there is a real risk of over-interpretation through extrapolation of limited data. Association is not causation.

Misinterpretation of surveillance data is a serious issue. Surveillance data needs to come with a warning label - Open to biases - interpret with caution! Some may not realize that surveillance often does not measure all infection, it's a proxy for actual disease incidence.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.
https://t.co/FBfXhUrH5d
Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.
...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.
Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
