I teach politics at a university in the UK. I'm interested in electoral systems, public opinion, and the politics of non-majoritarian institutions like courts and regulators. ORCID: 0000-0002-8932-9405

I think this paper in part reproduces a measure of "intra-party unequal representation" found in "A unified approach to measuring unequal representation" doi.org/10.1007/s111... which very unfortunately is not cited

A unified approach to measuring unequal representation - Public Choice

The concept of unequal representation is commonly understood through the lenses of disproportionality and malapportionment, pertaining to inter-party and inter-district aspects, respectively. Popular indices used to measure such features are analyzed separately despite being mathematically identical. District-level wasted votes are not measured in terms of unequal representation, even though they can be conceptualized as intra-district unequal representation. A new component, intra-party unequal representation, which measures unequal representation across districts for voters who support each party, has not been considered to contribute to unequal representation. We propose a unified approach for measuring these components—disproportionality, malapportionment, wasted votes, and intra-party unequal representation—by using $${\alpha }$$ α -divergence. We show mathematically that the total of disproportionality and intra-party unequal representation equals that of malapportionment and wasted votes. We apply this approach to the Japanese political system and demonstrate the role of intra-party unequal representation in sustaining disproportionality in favor of the Liberal Democratic Party.

NEW - Disproportionality in Geographic Representation - https://cup.org/4fLxlL5 - Orit Kedar, Yair Amitai & Gilad Hurvitz #OpenAccess

BJPolS abstract discussing geographic representation in elections. Highlights geographic disproportionality between votes and party seats, using data from 113 districts across twelve democracies.

The social psychologist Solomon Asch once conducted an experiment. He presented participants with the results of a study of American soldiers. American soldiers are stoic and uncomplaining. They lack initiative.

Man from the council came round to do a safety check of the playground outside, incl a tree trunk walk. He kicked every one of the fake tree trunks to check they were stable. Did he do the walk himself? No, he did not. Shame!

In 2021, the Ortega-Murillo regime arrested all major opposition candidates for the presidency on trumped-up "treason" charges and forced hundreds of activists and journalists into exile. Now they have dropped all pretenses of electoral legitimacy. www.theguardian.com/world/2026/j...

Once again asking myself how small/niche a research "field" can be. My working hypothesis is "convinces enough academics to fill a special issue", but today this is being tested.

The first is that PD, M5S and other minor parties on the centre-Left are headed towards an electoral pact. This means the two coalitions will be roughly evenly sized. This means that even if the Right comes first in 2027, the majoritarian component of MMM may not be enough for a majority. (5)

This is nerdy but important. A new Third-Party Courts and Tribunals Data Licence has just been launched, free of charge, letting approved orgs - including journalists (& researchers?) - analyse court data Potentially a big boost for open justice. Court listings have previously been an opaque mess.
