I commend Andrej Karpathy’s pedagogical work, e.g., Eureka Labs’ vision and his instructional videos. His insight that students must be proficient in AI but should be able to exist without it, is spot on. He also suggests leaning on in-class evaluation to ensure academic integrity. While a shift to in-class is clearly necessary, basing it solely on grading implications sounds too narrow.

In-class time will play a bigger role.

This is one of the reasons we have a number of recent teaching innovations in-class, including Hackathons for predictive modeling and reinforcement learning (multi-armed bandits), and LLM-assisted development deployed to HuggingFace.

LLMs can help make learning fun and engaging, starting in the classroom.

The most effective teaching fosters student ownership of learning. This involves showing that learning is fun (and surely challenging). LLMs offer an opportunity to strengthen this message. Learning is even more fun now, and somewhat less challenging: LLMs make it much easier to access material, test understanding, iterate on solutions, experiment, and get quick feedback.

That’s why we will next dedicate more of the in-class time to demonstrating how to use LLMs as life-long learning companions without mindlessly delegating our understanding. To read more about this difference, you can see the slides from my talk Mind the AI Gap: Understanding vs. Knowing here.

In all, yes, in-class time needs to be more strategically used, but making grading the sole driver represents a missed opportunity. Using more of the in-class time to model the joy of discovery and learning with LLMs (“the pleasure of finding things out”) can be a better primary driver.

It’s not every day that causal evidence is quoted in the headlines. Incidentally, we had a similar (unpublished) study on Instagram looking at the effects of “Instagram perfect” on users’ prosocial behavior (also through social comparison as the mechanism), with somewhat parallel results.

So, I am not surprised at all by this finding:

To the company’s disappointment, “people who stopped using Facebook for a week reported lower feelings of depression, anxiety, loneliness and social comparison,” internal documents said.

This is slightly off-track, but I felt compelled to share this opinion piece. The NYT published an opinion video featuring Jack Conte, musician and CEO of Patreon. The message is simple: algorithms should serve people instead of people serving algorithms.

The piece reminded me of the times when you could reliably follow someone. These days, I see all kinds of content that I didn’t sign up for, and I miss the content from the people I thought I followed. I don’t even see the updates from my connections.

As a workaround, LinkedIn wants you to “double follow” if you want to really follow someone. You need to visit a person’s profile and click on the unlabeled, literally hidden bell in the upper right to get notified when that person shares something.

Isn’t that a little preposterous?

The opinion piece suggests that we must:

1. Prioritize long-term relationships
2. Fund art, not ads
3. Put humans in control

As a technologist, I agree. This may sound like a rant, but it really is not. I think Jack is doing an excellent job making people question the existing design (and offering an alternative?).

I’ve created a gift link so you can access the content without a NYT membership, see here.

If the goal of teaching is learning, then how exactly does the brain make a difficult concept instantly clear?

I’ve been a student of how the human brain works for as long as I can remember, particularly since the early days of my teaching. Teaching is moot if actual learning lags. Learning is difficult by definition, and making it sticky is even more challenging.

This article provides a status update on research into what “insight” is, how it is formed, and how it aids learning and long-term memory. Worth a read.

In the age of generative models, a better understanding of how insight is formed and the role of cause-effect triggers (water rises – Eureka!) is increasingly valuable.

Did you know about stackoverflow.ai? I must’ve completely missed this. It looks like a great alternative to the search function on the site (or using Google to search it). We seem to have come a full circle from LLMs killing StackOverflow to LLMs powering StackOverflow for search and discovery. Recommended.

The intro sections and DAGs for the RD chapter are in. More to come.

I’m looking for interesting datasets for the RD design. I have some candidates, but I’m eager to find more compelling, real data. Ideally, I’d like a business case (rather than policy), such as one on customer loyalty status. The IV chapter already uses policy data (tax on cigarette prices vs. smoking). Please comment with a link if you have ideas beyond the Kaggle datasets.

As a reminder, Causal Book is an accessible, interactive resource for the data science and causal inference audience. It is not meant to substitute for the excellent texts already available, such as The Effect by Nick Huntington-Klein and The Mixtape by Scott Cunningham. This book aims to complement them by focusing on the idea of solution patterns, with code in R and Python, exploring different approaches (Freq. Statistics, Machine Learning, and Bayesian), and clarifying some of the counterintuitive (or seemingly surprising) challenges faced in practice.

This is interesting: Palantir has launched a “Meritocracy Fellowship” to hire high-achieving high school graduates right out of school, offering a paid internship with a chance at full-time employment. The company presents this as an alternative to college.

This is a very limited, transactional view of college. College is more than just training for employment; it is where students gain knowledge and broaden their horizons, learning how to think and ask questions, in addition to acquiring practical skills. I doubt a four-week history seminar will make up for all that.
