This is really worth reading, not least as it highlights how the 'Hero Voter' idea has been twisted beyond all recognition in most commentary and Westminster briefing.

As Maria Sobolewska and I first said in Brexitland, the legacy parties under FPP are like Tinkerbell - they need belief to survive. if people cease to believe they see the best and only options, they can die fast. Is this the moment Labour’s Tinkerbell dies?

Well, no, they’re not just as wrong. The bigger error is not seeing that β€œtrying to win over voters from a party on the opposite end of the spectrum, whose values your core voters oppose” is not same as β€œchasing voters from party on same side ideologically whose values your core voters like.”

Here's a table in the new @britishelectionstudy.com book (forthcoming). We calculated 'second preferences' - here Labour voters after elections 2015 to 2024.

50% of Labour's 2024 voters had Greens as second preference. 42% the Lib Dems. The left bloc is coalescing behind the most viable left party!

Labour should have focused the campaign more on what voters really care about: the licensing terms of critical national geospatial datasets.

Is there really a 'quiet revival' of religion among Gen Z? A fierce debate is taking place about whether there really has been a revival in Christianity.

Online political discussions are characterized by a minority of users dominate the discussion, while most remain silent.

Those who perceived a discussion as toxic/polarized tend to remain silent: But toxicity engages power users (namely men interested in politics) www.science.org/doi/10.1126/...

This is very cool, and amazing data!

Looking forward to reading the report in full later

A flow chart shows 17.4 million leave voters in 2016, vs 16.1m remain. In 2025, 5 million of those people have died, and 3 million new voters have come of age.

The result (plus some people changing their mind) is 19.8 million voters now back rejoin, versus just 11.7 million wanting to stay out.

How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...

Do Shared Demographics Make You More Persuasive on the Doorstep? - Campaign Lab Campaigners often assume that people are more likely to be persuaded by someone who looks or sounds like them, someone of a similar age, gender, or background. After all, research has long shown that ...

πŸšͺResearch suggests that the idea that voters are more persuaded by people who look or sound like them is a myth.

In our new blog post we break down the evidence that demographics matter much less than the content of the conversation.

🚨Data Update 🚨

We have released an updated version of our panel data. This version includes a correction to our p_ethnicity variables, which affected 7.8% of our respondents. There is also a very small correction to our geographic variables.

Or, the response should be (using whichever method) let's spend more time learning about why effects look different in the field, so we can better project what we learn from surveys where it "matters"

Also the reply then should not be: let's do observational.

No, the reply then should be: let's do field experiments. ;)

I don't read the criticism as saying "survey experiments are bad", more, "this is an unbalanced diet"

(Okay maybe not _the_ most important, but at least equally important to the ATE)!

I agree but I think we're wrong to see it as an entirely technical question -> the compliance rate is often _the_ most important question in determining whether something "works" but we spend remarkably little time thinking about what determines it

Screenshot of text reading: "Nevertheless, experimental results can always be questioned on their generalizability, and framing effects are no exception. The major worry in this respect is that
framing experimentsβ€”like experiments in mass communication generallyβ€”typiοΏΎcally obliterate the distinction between the supply of information, on the one hand,
and its consumption, on the other. That is, experiments are normally carried out in
such a way that virtually everyone receives the message. The typical experiment
thereby avoids a major obstacle standing in the way of communication effects,
namely, an inattentive audience, lost in the affairs of private life. By ensuring that
frames reach their intended audiences, experiments may exaggerate their power.
A more balanced reading of frame effects requires methodological diversification,
experiments and studies oriented to the world outside."

I think this point is nicely stated by this quote in Kinder's critique of the framing literature

Not Getting the Message on Climate? Attention as a Key Barrier to Mass-Marketing Experimentally-Validated Messages | British Journal of Political Science | Cambridge Core Not Getting the Message on Climate? Attention as a Key Barrier to Mass-Marketing Experimentally-Validated Messages - Volume 55

For me the concern that we don't spend enough time thinking carefully about how treatments & effects _would_ translate if applied in the field - people accept that a survey exp lacks ecological validity, but then stop there

I think Carnes and Henderson show an alternative approach quite neatly

Whilst survey experiments are useful (and clearly popular), their proliferation is a bit troubling in light of papers like Carnes and Henderson (2025) - especially when studying questions where results (should) directly inform practice in "the field"

Only a few days left to apply for this fully-funded collaborative PhD with @lsegovernment.bsky.social and @campaign-lab.bsky.social!

It's a pretty unique position sat right between academia and "real world" campaigns - please share with someone who might be interested (and/or apply)!

Could not recommend this highly enough - LSE is a great place to be doing a PhD, and Campaign Lab are a fantastic organisation to collaborate with -

More than happy to talk to anyone thinking of applying!
