Ms. Rachel: "Ed Sheeran had an opportunity…Instead he caved to people who refuse to accept what the world knows." "If more than 20,000 white children were killed…everyone would be shouting…Treating some children's lives as less worthy of outrage is racist. Silence during a genocide is not neutral."
Ms. Rachel post:
"Ed Sheeran had an opportunity show that we won't be bullied into punishing people for supporting Palestine. Instead he caved to people who refuse to accept what the world knows. A genocide is happening in Gaza. We all need to speak out against it.

"If more than 20,000 white children were killed in another part of the world, everyone would be shouting about it at their concerts. Treating some children's lives as less worthy of outrage is racist. Silence during a genocide is not neutral."

In the name of competitiveness and defence, the EU is going backwards on climate action. €800 billion has been committed to prepare for war by 2030, far outstripping anything that is being invested in climate resilience and a green transition. This is madness. www.irishtimes.com/opinion/2026...
irishtimes.com
Opinion: Europe needs to start treating the climate emergency as a threat to our national security
Idea that climate action is about individual responsibility is as ridiculous as suggesting everyone can equip themselves to fight in war

All solidarity to my brilliant former colleagues at Exeter. The careful, deliberate dismantling of british higher education by its nominal 'leaders' - focused especially on the arts & humanities - is going to be rememberd as one of the major scandals of this generally awful/scandalous age.

Also I feel very much like I was just at an Enterprise Ireland announcement, not a Research Ireland one. Major focus on industry, commercialisation of research, turning scientists into entrepreneurs, creating a talent pipeline for industry, and an overriding theme of fairly ill-defined "scale".

These numbers should be amplified everywhere there is a flat surface. The 3,000 person sample size was statistically significant. The direction of travel is positive but runs directly contrary to the perception born in the echo-chamber of Twitter-brained media and politics. (H&CC is a client)

Year-on-year datasets tracking changes in public sentiment in Ireland between 2024 and 2025 show
that 66% agree that immigrants contribute positively to Irish culture and community, which is up 2% up from 64% in 2024.
79% believe working-class people are struggling due to systemic inequality which is also up 2% from 77% in 2024.
Those who believe wealthy people are successful because they were given more opportunities than others has risen from 63% in 2024 to 69% in 2025.
The number of people who support the freedom of transgender people to live their lives is up 5% up from 70% in 2024.
80% agree that Black, Asian and minority ethnic communities face greater barriers to success than white people, up 5% up from 75% in 2024.Research Framework
Ireland in Focus draws on multiple sources of data to provide a clearer understanding of how hate, disinformation and far-right mobilisation are evolving across Ireland in
2025. This includes H&CC's analysis of far-right developments in political organising, informal networks and far-right agitators, giving insights into how narratives, mobilisation and organising strategies are emerging and shifting.
company Dynata. The data was independently weighted by Ireland Thinks using demographic and methodological controls such as age, gender, ethnicity and voting behaviour at time of poll fielding to ensure representativeness and statistical robustness. The consistent methodology across both waves allows for reliable year-on-year comparison of sentiment and social trends and the large sample size gives high levels of statistical significance.
Ireland in Focus also draws data from 89 communities' crisis responses (49 in 2024 and 40 in 2025) supported by H&CC to capture how local communities responded in real time to moments of tension, protest and disinformation.
Ireland in Focus, assesses public attitudes through two large, nationally representative, anonymous surveys conducted in 2024 and 2025, each with approximately 3,000 respondents via independent polling
The consistency in design across both years provides a robust basis for tracking how attitudes are shifting - making this one of the first datasets of its kind in Ireland to capture changes in public sentiment over time. Finally to understand how narratives were spreading and evolving in the public sphere, narrative benchmarking was analysed using a commercial social media research tool.
