Around 7% of the population I believe, so I was assuming a higher proportion of households - but I don’t know the stats on household composition, will defer to you!

Which probably wouldn’t apply to the consistent downward trend over previous months but might be a factor in this month’s jump, depending what next month shows

There must be a certain amount of month to month noise in here too - of the 60,000 households in the survey, I imagine maybe 10% have a Black woman as a member? And although 6,000 is a decent sample size, you’d expect about a 1 percentage point swing by chance, one month in every 20

Hi! Sorry, have been on here much less recently and just saw this. It doesn’t make much difference to my royalties either way, so if you want to save money and it suits the recipient, the Kindle version at £2.99 is fine (I’ll get 60p). Otherwise an Amazon or bookshop copy will get me a pound or so!

49 for me. Exhausting but absolutely worth it. Would say you need to be prepared for a year or two of lower work productivity, if that is an issue income wise!

Hello tiny band of followers! Shortly I will be asking people in London to join me in an experiment in observation. I’m telling you now because a) I would be very grateful for any RTs going spare and b) I probably will repeat it a few times in the next few days. Ok thanks love you byeeee

If I were running Labour comms I would commission an app called 'Will the Tories/Reform deport you?' then let the reactions on TikTok and Instagram do their work.

genuine quote: "When I announced my divorce, I didn’t do it in a breakdown video. I did it in partnership with OSEA – a skincare brand I genuinely love. The tagline was simple: Glowing Through Divorce" followed by "These are the collaborations that resonate most, because they aren’t manufactured"

Unsurprising. I read these articles and they came across to me like Cohan was trying to drive the bonds to zero just to prove that he can. His coverage of Musk's X buy was also weird; he kept claiming X would run out of money when it was obvious Musk would just put more in nypost.com/2025/10/08/b...

if someone is 'setting up a new data centre' I suppose you need to ask if they're going to just provide a building for Google to run servers in, or if they _are_ Google in which case they are also setting up a new region of their cloud

Leigh Caldwell @cognomist.bsky.social · 15/10/2025
there's a fair bit of technical engineering stuff but nothing too proprietary or difficult in setting up the actual physical facility. On the other hand running the cloud infrastructure that sits *in* most data centres (virtual servers, routing of data, optimising storage etc) is much harder

And also complicated by the fact that aggregate statistics might not be true of subgroups. But you are certainly right that a simple equation of poverty = racism is far from true.

Leigh Caldwell @cognomist.bsky.social · 15/09/2025
A common poll finding is that people don’t really know what the economy is like or how it’s doing. Much more about perception than reality. (eg in the leadup to US elections, most people thought unemployment was high even though they themselves had a good job). So it’s hard to draw these conclusions
110
Leigh Caldwell @cognomist.bsky.social · 15/09/2025
That’s true. I think Dan’s point about despair is probably more relevant than a simple economic equation. And maybe we just need to outvote the 8% and that’s that. But somehow the 8% managed to affect the rest of our politics enough to win the Brexit ref, so ignoring them may not be enough.

Leigh Caldwell @cognomist.bsky.social · 15/09/2025
I don’t necessarily disagree with you on this point about liberal democracy, by the way. But if the “economic anxiety” hypothesis has anything to it, which is an open question in my view, it isn’t disproved by Richard Tice being wealthy

Leigh Caldwell @cognomist.bsky.social · 15/09/2025
No I don’t really believe that the Telegraph or Richard Tice do hold these views, in any way that matters. I believe it matters why a few million people in the country hold those views (which could be because they listen to Richard Tice; or because of other cultural, personal or economic causes).
100
Leigh Caldwell @cognomist.bsky.social · 15/09/2025
Clearly the dynamic pushing Richard Tice, or the Telegraph, to be more extreme is not the same as the one that directly influences a Reform voter or Telegraph reader. These figureheads exist to funnel/reflect/amplify the feelings of others, not to have meaningful opinions of their own.

And are generally much more productive. The main good thing about small firms is that they occasionalally become big firms!

There is also no binary racist/not racist distinction (maybe this is even true of fascist/not fascist). No point trying to get into whether a whole crowd either is or isn’t racists, whatever answer you end up on will miss the deeper points and the levers of change

You remind me of the UK state’s fetish for signing long-term contracts for public services with private providers to avoid taking debt onto its balance sheet, then having to pay the private companies’ (much higher) finance costs/risk premiums instead of financing it themselves.

I wondered that too. Perhaps the modelling doesn’t indicate any big returns from reforming it (as annoying as it is). Possibly it is encouraging additional pensions contributions as an unintended side effect, and we need to keep anything that compensates for our weak pension savings rate!

I’ve been frustrated to see so much of the ongoing story about asylum seekers and the protests against them covered without hearing from those seeking asylum and now being met with hostility and hatred I set out to speak to those directly affected to find out about the impact this is having 👇

At this point I have less and less interest in a strategy for Labour to be re-elected (except insofar as that stops Reform winning); a strategy to stop making the country more racist would be enough.

Leigh Caldwell @cognomist.bsky.social · 05/09/2025
I keep desperately trying to figure out if there’s a strategy or a rationale for all this, or even a reason to hope things might get better. The straw I’m clutching at today is: people talking so much about migration now that they’ll be bored and other issues will be salient in 4 years. If only.

V. interesting. The "island of strangers" speech happened serendipitously (in one sense) during a panel survey. Paper uses this natural experiment to see the effect of such migrant-sceptic interventions on individual perceptions and voter intentions. Upshot: it harmed Labour for no obvious benefit.

@dianecoyle1859.bsky.social “…it seems unreasonable that a man is taxed because he possesses and occupies a house with a garden, when others having a caravan, a houseboat, a yacht, a painting by an old master, or a washing machine, do not pay tax on that property.” He’s right! Tax them all!
