New brief report in @jmfncfr.bsky.social We follow earnings of male same-sex couples in 🇩🇰, 🇳🇱, and 🇸🇪 around the time they become parents. Main takeaway: not much changes for them! Also: no signs of long-lasting specialization based on pre-parenthood earnings or biological relatedness to the child.

Got to present this early draft paper today at a neat workshop organized by @rohanalexander.bsky.social. It's my attempt to grapple with the need for struggle and friction in learning in a world where LLMs remove all that friction. Read the whole thing at stats.andrewheiss.com/pinky-lychee/
AI for Me, Not (Yet) for Thee? Desirable Difficulties and Deliberate Friction with LLMs

Author: Andrew Heiss

Affiliation: Andrew Young School of Policy Studies, Georgia State University

Latest version: May 1, 2026

Details: This is a short position paper written for the Toronto Data Workshop’s 2nd Colloquium on Applications of AI, “Notes on the Future of Quantitative Social Science,” held at the University of Toronto on May 1, 2026.

Abstract: I am simultaneously a critical skeptic of large language models (LLMs) and their role in the learning process, and a reluctant and wary user of those same tools in my own work. This essay is an attempt to work through this tension by examining how LLM-based tools shape and reshape the foundations of expertise required to use them. If learners can generate working code through a Google search, if they can upload a blank problem set template and get a completed assignment in seconds, and if they can design, carry out, and analyze research projects in minutes, how can they build the expertise that is required to work with LLM output? Relatedly, if experienced researchers spend the bulk of their time reviewing LLM output and not working through code themselves, what happens to their expertise? The answer to these questions, I argue, is to deliberately introduce difficulty and friction in quantitative work, allowing learners to build expertise and helping experienced researchers maintain it.

For unpaid #carers, earning more does not always lead to economic security. Motivated by the recent #Carer's #Allowance scandal, I have a new working paper @usociety.bsky.social on how much insecurity carers experience, for how long, who's most exposed and why: osf.io/preprints/so... 1/2
The figure shows reports of economic insecurity plotted against earnings from paid work. Earnings increase from left to right. At zero, earnings cross the Carer's Allowance limit of around 150 GBP per week. Past this limit, a carer loses eligibility for the allowance. 

Carers who never report receipt of the allowance in the survey experience less and less insecurity when their earnings are higher. 

For those with a history of benefit receipt, instead, insecurity doesn't decline smoothly. Arrears, the inability to save regularly, and money worries all spike past the earnings limit set by the allowance.

I just whipped up this little #QuartoPub site last week that demonstrates how I teach p-values/hyp-testing through simulation both with live OJS and with #rstats, and I think it's super neat! It has examples for diff-in-means, diff-in-props, and regression slopes nullworlds.andrewheiss.com #statsky
Simulated null distribution for data with a sample size of 100, difference in group means of 5, and a p-value of 0.142Simulated null distribution of a slope of 0.8 and p-value of 0.002Finally, we have to decide if the p-value meets an evidentiary standard or threshold that would provide us with enough evidence that we aren’t in the null world (or, in more statsy terms, enough evidence to reject the null hypothesis).

There are lots of possible thresholds. By convention, most people use a threshold (often shortened to α) of 0.05, or 5%. But that’s not required! You could have a lower standard with an α of 0.1 (10%), or a higher standard with an α of 0.01 (1%).

Statistically significant
The p-value is < 0.001 and our threshold for α is 0.05

In a world where there is no relationship between x and y, the probability of seeing a slope of at least 0.901 is < 0.1%

Since < 0.001 is less than 0.05, we have enough evidence to say that the slope is statistically significant.

Evidentiary standards

When thinking about p-values and thresholds, I like to imagine myself as a judge or a member of a jury. Many legal systems around the world have formal evidentiary thresholds or standards of proof. If prosecutors provide evidence that meets a threshold (i.e. goes beyond a reasonable doubt, or shows evidence on a balance of probabilities), the judge or jury can rule guilty. If there’s not enough evidence to clear the standard or threshold, the judge or jury has to rule not guilty.

With p-values:

If the probability of seeing an effect or difference (or δ) in a null world is less than 5% (or whatever the threshold is), we rule it statistically significant and say that the difference does not fit in that world. We’re pretty confident that it’s not zero.
If the p-value is larger than the threshold, we do not have enough evidence to claim that δ doesn’t come from a world of where there’s no difference. We don’t know if it’s not zero.
Importantly, if the difference is not significant, that does not mean that there is no difference. It just means that we can’t detect one if there is. If a prosecutor doesn’t provide sufficient evidence to clear a standard or threshold, it does not mean that the defendant didn’t do whatever they’re charged with†—it means that the judge or jury can’t detect guilt.
