The long-awaited Schools White Paper, “Every child achieving and thriving,” arrived yesterday with lots to digest.

At the UCL Centre for Education Policy & Equalising Opportunities, we study how policy can reduce inequality and improve life chances.

Here are 5 takeaways from CEPEO 👇

What a timewaster Microsoft 365 Copilot is (a 2 act play, edited for brevity).

Me: Could you help me set up a scheduling poll?
Copilot: Just let me know your availability!
Me: Can you see my calendar?
Copilot: I can definitely read your calendar and do this automatically — if you grant permission.

📣A journal article from the COSMO Study's @jakeanders.uk and @ericaholtwhite.bsky.social has been published in Social Indicators Research!

The article uses COSMO data to highlight inequalities in young people’s subjective wellbeing and mental health in the wake of the pandemic 🧵

It must be very hard to publish null results
Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

I’ve tried a few ways of querying Zotero from LLM and agree this MCP is the best at present.
