The Bakerloo line trains are also the oldest passenger trains anywhere in the country, at 53 years old. They’ve been running for 20 years longer than the Central line trains!

My job would be so much easier if correlation was causation😔

So it was important to remember that the offenders I was coming into contact with were a tiny and unrepresentative minority of a much larger community that I rarely met. But I can see how easy it would be to forget that if you’re not alert to the risk.

What you described certainly matches my experience. Where I grew up meant I knew lots of Asian kids but few Black people. So when I was policing the Tube in Wembley in 2006, the only Somali teens I’d ever met were those we were arresting for robbery and I no other experiences to balance against.

I've been wondering recently how many racist police officers were racist when they joined, and whether part of the issue is logical fallacies arising from having a lot of contact with very narrow sections of society in places with which they may not otherwise be familiar.

Those are all part of the reasons why rates of pedestrian fatalities have long been higher in the US than in other developed countries. But the recent increase in the US is better explained by larger, heavier vehicles.

Matt Ashby @mattashby.com · 2d

The rise in pedestrian fatalities in recent years seems to be specific to the United States – in other developed countries, pedestrian fatalities of either continued to fall or have flatlined.

usa.streetsblog.org/2020/10/10/e...

Bar chart showing cyclist fatality rates per 100 million km biked in five countries across three periods (2000–2002, 2008–2010, 2016–2018). The U.S. shows the highest fatality rates in all years and is the only country where fatalities rose in the latest period, increasing from 4.5 to 6. All other countries, including the Netherlands, Germany, the U.K., and Denmark, show steady declines or flat rates over time.

Great podcast discussion between @jeffasher.bsky.social and Michael Lewis (author of Moneyball, The Big Short, etc.) about the difficulty of communicating crime patterns to the public.

Crime scripts are widely used to work out where best to intervene to stop crime, but this article uses several case studies to illustrate how scripts can also be used in investigations of serious crimes when there are competing theories of the crime.

I don’t think it matters much what you or I believe. Just Say No doesn’t work when educating young people about illegal drugs or risky sex. Why would it work when teaching young people about AI?

But the risks associated with using LLMs can be minimised, and it’s not particularly difficult to do so. It’s certainly well within the capabilities of most students if guided well.

Matt Ashby @mattashby.com · 5d

Prohibitions are often accompanied by attempts to reduce harm. Safe consumption rooms for drug users, heroin replacement therapy, and drug-safety testing in nightclubs, for example. Also designated street prostitution tolerance zones in non-residential areas.

Matt Ashby @mattashby.com · 5d

A brief (and not necessarily well thought out) argument from me on why trying to ban students from using AI when writing essays is like abstinence-only sex education, and will fail for the same reasons.

I’d be interested in others’ thoughts on this, especially constructive (🙏) disagreements.

Matt Ashby @mattashby.com · 5d

I think the problem with the argument by @ubisurv.net in this article is that he’s doing the same thing to students that he complains the university is doing to him: leaving students to navigate on their own decisions about LLM use with minimal guidance.

…

Matt Ashby @mattashby.com · 5d

Surely it would be better for us to say to students ‘using LLMs comes with these risks and these harms, but if you do use them then this is how to minimise that risk to the extent you can’?

Matt Ashby @mattashby.com · 5d

Unless LLM use is designed out of an assessment (eg a handwritten unseen exam), many students will use it. And as with abstinence-only sex ed, prohibiting LLM use just leaves students with no guidance at all on how they can use them in the safest way possible.

A policy of prohibiting/strongly discouraging LLM use in all circumstances will fail for the same reason abstinence-only sex ed fails: the temptation to ignore the prohibition is simply too great.

If you teach media and crime, this looks like it would be a very useful introductory reading:

Our World in Data @ourworldindata.org · 5d

Does the news reflect what we die from?

The image presents a comparison of the leading causes of death in the United States for 2023 and the media coverage these causes receive from three news outlets: The New York Times, The Washington Post, and Fox News.

In the footer, it notes the data sources, indicating that the information is based on media mentions from Media Cloud (2025) and death data from the US CDC (2025) and the Global Terrorism Index, with a clarification that values are normalized to sum to 100%.

Interesting blog post arguing that as well as researching the reasons police sometimes use excessive force, it’s also important to understand the harms caused by police *not* using force when it is necessary to do so.

Were you able to get any comment from Hackney Council on why they rejected the previous applications and why the process has taken so long?
