honestly, I hope this paper leads to some serious discussion because it has some key important learnings.

also I think some of us feel like we missed a beat in not labeling it the 'moustache' effect (as we do in private), so we'll have to be happy with M or W effects in public.
Highlights The midpoint of the left–right self-placement item is hiding important political diversity and may be conflating moderate responders with populists and other political subgroups. Survey researchers should consider this problem when examining relationships between political orientation and political attitudes. We suggest testing for nonlinearity in these relationships, and measuring anti-establishment and populist beliefs separately. Researchers interested in building theories explaining the psychological underpinnings of ideological extremism should also consider the possibility that a qualitatively different type of ideological extremist self-places on the midpoint.

my kind of research. cycling and politics!

"We find that even brief, positive interventions move
votes away from the far right, which is in line with the left-behind accounts"

Cycling through Elections: The Political Consequences of the Tour de France Ala Alrababah Maelle Delouis-Jost Germain Gauthier Adam Polak Abstract Do place-based interventions that raise visibility and economic activity affect far-right voting? We study the Tour de France (TdF) as a case of brief but visible exposure that combines economic activity with symbolic recognition. Using variation in the annual TdF route between 2002 and 2022, we show that exposed municipalities experience declines in far-right support of 0.03–0.04 standard deviations. The effect exceeds 0.1 standard deviations in recent elections and is strongest in poorer areas and in towns with high prior far-right support. We find evidence consistent with the symbolic mechanism and mixed evidence for the economic one. TdF exposure increases local GDP per capita, effects on voting are larger when French riders win stages, and a two-wave survey around the 2025 TdF provides suggestive evidence that residents in exposed towns report greater recognition. These results contribute to research on geographic inequalities, symbolic politics, and the consequences of place-based interventions.

this morning, a sobering and important read

It’s (a) Shame: Why Poverty Leads to Support for Authoritarianism
@neerdaels.bsky.social, Tröster & Van Quaquebeke

journals.sagepub.com/doi/full/10....
Abstract The literature has widely discussed and supported the relationship between poverty and support for authoritarian leaders and regimes. However, there are different claims about the mediating mechanism and a lack of empirical tests. We hypothesize that the effect of poverty on support for authoritarianism is mediated by shame: People living in poverty frequently experience social exclusion and devaluation, which is reflected in feelings of shame. Such shame, in turn, is likely to increase support for authoritarianism, mainly due to the promise of social re-inclusion. We support our hypothesis in two controlled experiments and a large-scale field study while empirically ruling out the two main alternative explanations offered in the literature: stress and anxiety. Finally, we discuss how the present findings can support policymakers in efficiently addressing the negative political consequences of poverty.

here are two examples of expert science communication around the links between paracetamol/tylenol and autism--responding to medical myths.

on the left is a good example, where the myth is raised, explained, evidence provided to explain lack of support for the myth.

one on the right, not so much.
Australia’s peak medical body, the Australian Medical Association (AMA), said no studies supported the Trump administration’s claims linking paracetamol to autism in children. The AMA president, Dr Danielle McMullen, told ABC radio that some studies had shown an “association”. “But there’s also been really large studies showing that there’s no association,” she said. “And it’s important to remember that association doesn’t mean cause. It could be that there’s a whole range of things that happened during pregnancies, and one of those was that the pregnant mother took paracetamol, but it also could be that she had a fever or there were genetic factors. “In fact, in autism, it’s most likely that autism is linked with genetic factors as its primary driver but we really don’t know the full cause of autism.” Scientific research has shown there might be a link between paracetamol use in pregnancy and autism, but no causal relationship has been proven. “Evidence is mixed,” said Associate Professor Kevin Yap from La Trobe University. Australian researchers have also warned that, contrary to Trump’s advice, there are risks from not treating high fever during pregnancy. A sustained high fever is associated with an increased risk of miscarriage, stillbirth and fetal malformations. Experts advise that paracetamol is the safest way to control a fever in pregnancy.

good point. I think pushing the narrative that taking them separately is somehow safer--despite the available evidence, but you know feelings!--not only erodes confidence, but a bunch of other factors that feed into vaccination decision (see BeSD framework)

once again, almost 70yrs ago social psychologists were talking about this with failed prophecies for 'cults'. the four conditions continue to strengthen the belief, despite evidence of disconfirmatory evidence.

en.wikipedia.org/wiki/When_Pr...
Conditions for increased fervour after disconfirmation Condition Effect "1. A belief must be held with deep conviction and it must have some relevance to action, that is, to what the believer does or how he or she behaves." Makes the belief resistant to change. "2. The person holding the belief must have committed himself to it; that is, for the sake of his belief, he must have taken some important action that is difficult to undo. In general, the more important such actions are, and the more difficult they are to undo, the greater is the individual's commitment to the belief." Makes the belief resistant to change. "3. The belief must be sufficiently specific and sufficiently concerned with the real world so that events may unequivocally refute the belief." Exposes believers to the possibility of their belief being disproved. "4. Such undeniable disconfirmatory evidence must occur and must be recognized by the individual holding the belief." Exerts pressure on believers to abandon their belief. "5. The individual believer must have social support." While an individual might be unable to resist the pressure to abandon their belief in the face of disconfirming facts, a group might be able to support each other to maintain the belief.

I think I am pretty close to what looks like a line of best fit there
www.abc.net.au/news/vote-co...
Vote compass results showing Progressive/Left to Conservative/Right space across Social and Economic axes. Top left (More Progressive/Left) is Greens parth with my views just down and to the right a bit. ALP is quite centrist, just left on economic issues, with Liberal Nationa Party down a bit further on Economic and Social Right/Conservative with One Nation Party near bottom corner (Economic Right / Conservative)

watch out for the sociopathy and neoliberal effects on them newborn babies!
Newborn babies who are inadequate in iodine could be sluggish and tough to nourish. If they are not handled, they are likely to attain sociopathy, which will result in poor overall economic growth and cognitive disability [85].
