We have reached a sorry place when people are turning to AI for moral/ethical guidance. What’s right and wrong are not facts to be determined. They are judgments only human beings can or should make.

And in case you're wondering how it comes about that some offenders are prosecuted and other identical offenders are not, the answer lies in the fact that, at the margin and in some locations, prosecutors vary randomly in their decision to prosecute.

What is it with men, whether gay or straight, who feel that if they can’t be the sole object of someone else’s affection, no-one else can be either?

Would an interest rate increase of 2 p.p.have a bigger effect on demand if introduced in one step than if introduced in two steps of 1 p.p. separated by a three month lag? Does the shock have an effect separate from the cost increase?

Mark Nicholson, the infamous creator of ON cartoons ridiculing the health problems of politicians and depicting them as bloodied victims of stabbing attacks, thinks this is fair comment. May his chickens turn into emus and kick his foul house down.

Another person swept off a flooded road while foolishly assuming their vehicle is heavy enough to maintain traction. It’s worth remembering that until they fill up with water, cars (like ships) are actually quite buoyant

I’ve lost count of the number of politicians using taxpayer funds for illegitimate purposes. There’s a lesson here for young criminologists. Never underestimate the importance of incentive and opportunity as a cause of crime.

At Tokyo station if there are 30 people in front of you waiting for a taxi, the expected waiting time is five minutes. Wonder what it is at Sydney Airport.

The attack on Helen Haines was terrible but before we construct policy based on the assumption it was a politically motivated attack, can we collect all the relevant facts? Might have some bearing on how we should respond.

We should engage in more respectful debate, both in and outside Parliament. At this stage, however, we know next to nothing about the motives, beliefs, and mental health of Helen Haines’ attacker or about what triggered the attack.

The trouble with social media is that like guns and bombs they allow people to inflict pain without seeing he pain and harm they are doing

Great cycling trip this morning. Japan is very kind to cyclists.

Economists don’t seem very fond of matching to create control groups but (a) sometimes it’s the only option and (b) all econometric methods involve assumptions. Their plausibility depends on the setting and the supporting argument.

Eating lunch in Japan and suddenly every mobile phone in the cafe starts screeching. It was an earthquake warning. No one stopped eating. No sign of any earthquake yet.

The Greens don’t like violence. Not many people do. Ukrainians especially. Somehow I don’t think a polite request or reasoned argument would stop Putin’s aggression.
