New paper: real water-use behavior change using multi-year, metered data (19k homes). Not attitudes, identity, efficacy, or persuasion. We manipulated delivery mode + frequency of home use reports → ~2% reduction (~7 L/day here). 1/3

This later passage also reminds of Bem's classic 'how to write a good article' text in which he describes a lot of ways to increase error rates

This defense of verbal theories sounds much weaker in 2025 than it did in 2004

I should read these old works more often—it would help me argue from more basic principles why current practices are so ineffective

Also, "research involving self-reports often leads to fundamentally different results than research focusing on actual behavior in incentivized settings"

PNAS just asked me to order reprints for our recent commentary. For fun, I thought I'd see how much they cost.
25 prints—of just one page, mind you—646 USD. And then they have the temerity to charge 160 USD for shipping.
The for-profit publishers will take all we let them. Choose other journals.

Dutch police apparently fired guns 13 times in 2024. Just wondering, how many shots are fired by the New York city police every year? Yes, way more, particularly tasers (energy weapons). Kudos on them being so transparent, though.

We now have a fully electric heat pump that replaces our gas for heating and hot water. It reduces our monthly costs, and carbon emissions even more. We love it, happy to help other people and chat

An important distinction is that measuring behaviors means looking at behavior properties like frequency, duration, and intensity, and measuring person properties means looking at attitude/intensity strength, and vague and low-validity self-reports of typical behaviors. 2/2

I still complain about car/bicycle friction here in Amsterdam, but I shouldn't really. Such insane privilege to bike commute here. Picture is from Hungary, but it's not unique to there. I'm not dunking on our eastern neighbors.

I've been pleased to work these years in the former Geologic Institute building (1933) at the University of Amsterdam—nice space and interesting history. It's deeply ironic to find out it was co-funded by Royal Dutch Shell, since my lab focuses on mitigating climate change.

Do any modern governments practice elections for exclusion rather than selection? This actually makes sense to me. I might even wager that the bad candidates are more distinctive, and the virtuous ones more replaceable, although I don't know what evidence would help test that

I applied for an Associate Professor opening in my unit and was rejected (ostensibly due to space, not merit). Maybe it's time for a new relationship with my work. For so long it feels like I've been doing 110%. Part of integrating into Dutch culture might be backing off a bit.

Happy winter everyone. We put up our xmas tree. Here's a picture from when my dad was younger than I am now, up in the Sierra Nevada mountains, where my family used to spend xmas with the cousins.

This was my first dissertation proposal. It was not good. Afterward I pivoted to work on environmental issues. 12 years has come and gone, and a lot of growth.

Can scientists be viewpoint free? For a long time already, historians have accepted that there is no value-free perspective

This is a highway just south of Vienna, normally and today. It's hard to accept the expensive changes that are needed now, but it's worse to delay

A small thing to love about the Netherlands is the fresh ginger or mint tea in most cafes. This thin-sliced one in Nijmegen is particularly *POW*
