Quick takes

First in-ovo sexing in the US Egg Innovations announced that they are "on track to adopt the technology in early 2025." Approximately 300 million male chicks are ground up alive in the US each year (since only female chicks are valuable) and in-ovo sexing would prevent this.  UEP originally promised to eliminate male chick culling by 2020; needless to say, they didn't keep that commitment. But better late than never!  Congrats to everyone working on this, including @Robert - Innovate Animal Ag, who founded an organization devoted to pushing this technology.[1] 1. ^ Egg Innovations says they can't disclose details about who they are working with for NDA reasons; if anyone has more information about who deserves credit for this, please comment!

Animal Justice Appreciation Note Animal Justice et al. v A.G of Ontario 2024 was recently decided and struck down large portions of Ontario's ag-gag law. A blog post is here. The suit was partially funded by ACE, which presumably means that many of the people reading this deserve partial credit for donating to support it. Thanks to Animal Justice (Andrea Gonsalves, Fredrick Schumann, Kaitlyn Mitchell, Scott Tinney), co-applicants Jessica Scott-Reid and Louise Jorgensen, and everyone who supported this work!

The meat-eater problem is under-discussed. I've spent more than 500 hours consuming EA content and I had never encountered the meat-eater problem until today. https://forum.effectivealtruism.org/topics/meat-eater-problem (I had sometimes thought about the problem, but I didn't even know it had a name)

Im intrigued where people stand on the threshold where farmed animal lives might become net positive? I'm going to share a few scenarios i'm very unsure about and id love to hear thoughts or be pointed towards research on this. 1. Animals kept in homesteads in rural Uganda where I live. Often they stay inside with the family at night, then are let out during the day to roam free along the farm or community. The animals seem pretty darn happy most of the time for what it's worth, playing and galavanting around. Downsides here include poor veterinary care so sometimes parasites and sickness are pretty bad and often pretty rough transport and slaughter methods (my intuition net positive). 2. Grass fed sheep in New Zealand, my birth country. They get good medical care, are well fed on grass and usually have large roaming areas (intuition net positive) 3. Grass fed dairy cows in New Zealand. They roam fairly freely and will have very good vet care, but have they calves taken away at birth, have constantly uncomfortably swollen udders and are milked at least twice daily. (Intuition very unsure) 4. Free range pigs. Similar to the above except often space is smaller but they do get little houses. Pigs are far more intelligent than cows or sheep and might have more intellectual needs not getting met. (Intuition uncertain) Obviously these kind of cases make up a small proportion of farmed animals worldwide, with the predominant situation - factory farmed animals likely having net negative lives. I know that animals having net positive lives far from justifies farming animals on it's own, but it seems important for my own decision making and for standing on solid ground while talking with others about animal suffering. Thanks for your input.

The Belgian senate votes to add animal welfare to the constitution. It's been a journey. I work for GAIA, a Belgian animal advocacy group that for years has tried to get animal welfare added to the constitution. Today we were present as a supermajority of the senate came out in favor of our proposed constitutional amendment. The relevant section reads: It's a very good day for Belgian animals but I do want to note that: 1. This does not mean an effective shutdown of the meat industry, merely that all future pro-animal welfare laws and lawsuits will have an easier time.  And, 2. It still needs to pass the Chamber of Representatives. If there's interest I will make a full post about it if once it passes the Chamber. EDIT: Translated the linked article on our site into English.

I made a vegan vitamin supplement spreadsheet! It has vitamin ranges for many multivitamins available on amazon along with price/day estimations informed by this Vegan Vitamin Primer.  Inspired by reading this VOX article on Nutrition (and knowing that I should be taking vegan vitamin supplements for a while now): Just fyi, but the vitamin values in this spreadsheet ARE NOT informed by my own independent deep dive into all the potential vitamins I should be getting or the research behind it. I'm mostly relying on the expertise of this VOX promoted Ginny Kisch Messina, a vegan Registered Dietician with a Masters of Public Health. 

I recently wrote a post on the EA forum about turning animal suffering to animal bliss using genetic enhancement. Titotal raised an thoughtful concern: "How do you check that your intervention is working? For example, suppose your original raccoons screech when you poke them, but the genetically engineered racoons don't. Is that because they are experiencing less pain, or have they merely evolved not to screech?" This is a very good point. I was recently considering how we could be sure to not just change the expressions of suffering and I believe that I have determined a means of doing so. In psychology, it is common to use factor analysis to study a latent variables--the variables that we cannot measure directly. It seems extremely reasonable to think that animal pain is real, but the trouble is measuring it. We could try to get at pain by getting a huge array of behaviors and measures that are associated with pain (heart rate, cortisol levels, facial expressions, vocalizations, etc.) and find a latent factor of suffering that accounts for some of these behaviors. To determine if an intervention is successful at changing the latent factor of suffering for the better, we could test for measurement invariance which is an important step in making a relevant comparison between two groups. This basically tests whether the nature of the factor loadings remains the same between groups. This would mean a reduction in all of the traits associated with suffering. This would also seem relevant for environmental interventions as well.  As an illustration: imagine that I measure wefare of a raccoon by the amount of screeching it does. A bad intervention would be taping the raccoons mouth shut. This would reduce screeching, but there is no good reason to think that would alleviate suffering. However, imagine I gave the raccoon a drug and it acted less stressed, screeched less, had less cortisol, and started acting much more friendly. This would be much better evidence of tru

I've just written a blog post to summarise EA-relevant UK political news from the last ~six weeks. The post is here: AI summit, semiconductor trade policy, and a green light for alternative proteins (substack.com) I'm planning to circulate this around some EAs, but also some people working in the Civil Service, political consulting and journalism. Many might already be familiar with the stories. But I think this might be useful if I can (a) provide insightful UK political context for EAs, or (b) provide an EA perspective to curious adjacents. I'll probably continue this if I think either (a) or (b) is paying off. (I work at Rethink Priorities, but this is entirely in my personal capacity).
