How to not kill houseplants

Two simple lessons from a reformed plant murderer.

Should people pay to opt-out of vaccination?

Herd immunity is a public good, but mandating vaccination could be seen as an infringement on liberties and autonomy. On the object-level, I think a lot of people support the idea of mandatory vaccinations, but the meta-level principle 'the government should be able to force me to undergo medical procedures

What I've learned from failing at my goal of publishing everyday

Towards the end of December I set myself a challenge of publishing something everyday for 30 days - this was a big change from my previous habit of posting approximately never. I knew it was ambitious, but I really wanted to get out of a perfectionist mindset and put something

Can you trust productivity creators to try to give good advice?

A lot of productivity creators tell people things like: Unsubscribe from newslettersConsume less contentGet off social mediaWhich is interesting, since many of these creators make money from their audiences through these very channels. A useful thing to do when someone gives you advice is to think: Why are they telling

Skeptics in the Pub: Too dangerous to publish?

Navigating the high-stakes nature of AI researchThis Thursday I am giving a talk at Skeptics in the Pub Online! Skeptics in the Pub is high on the list of things I miss about the UK, so I'm very glad that I can still participate virtually. I'll be speaking about responsible

Win probability vs expected margin

I really like how the New York Times had visualizations of not just the win probability but also the expected margin of the recent senate elections. I'm not sure if this is new or if I just haven't noticed it before, but it's so much more intuitive. When I looked

The most irritating thing about iOS

A few months ago, I got my first ever iPhone. Until then, my smartphones were always Android. I don't think either is particularly better than the other, but since I use a Mac and an iPad it does make everything a little bit smoother, and I'm now so deep into

How surprised would you be if you failed?

Ali Abdaal recently posted a video in which he shares his "anti-wasteman" system for making progress on his bucketlist. A key feature of the system is asking the question "How surprised would I be if I failed in this goal?" and then "What are the top 3 reasons for this

Andrew Critch on AI existential safety

It can be very confusing to talk about issues in AI and ML since so many of the terms are overloaded, or have both technical and general meanings, or have shifted in meaning over time. Andrew Critch (with whom I used to work at CHAI) has written a comprehensive blog

Rosie's newsletter #2

Hi friends, Happy new year 🥂 In my last newsletter I said I wanted to publish more: I’m pleased to say I’ve posted something everyday since then! It was hard at times, but I'm really trying not to let perfectionism get the better of me. Like this newsletter, it’

Interstitial journal: first day back at work

Yesterday I wrote about how I'm attempting to start a whole load of new habits in one go, but that I was nervous about whether they would stick once I was back at work. I planned out a 'target day' to make sure I'd be able to fit in the

Complementary habits

Conventional wisdom on building habits warns against making too many changes at once. Generally, the advice is to pick one small thing first, and really focus on nailing that one habit before adding another. This has generally been my approach in the past, but over the last few weeks I've

My 2020 annual review process

In 2018, I did my first proper annual review. I followed the process outlined in this document, and it took absolutely ages. I followed the same process for 2019, and it was a little faster since I was mostly able to just describe what had changed since last year rather

Actualism: When it pays to accept second best

If I am trying to eat healthily, I know I should try to cook more at home. I also know that brown rice is more nutritious than white rice. I don't like the taste of brown rice as much, but a lot of healthy-eating advice encourages me to choose whole

Cat poetry

Loosely inspired by Senryū/Haiku Cat on my bed A furry boulder Where my feet should be Sitting like a loaf You eye up My sandwich Lounging on my keyboard The cat says prrrrrrrrrrrrrrrrrrrrrrrr,,,,,,,

Is the placebo effect real?

Mike Hall from the Merseyside Skeptics says of the placebo effect: “Confirmation bias means patients are more likely to notice and report changes that they are expecting and ignore changes they aren’t. The Hawthorne Effect means patients may alter their behaviour, simply because they are aware they are being

Choosing a blogging platform

Wordpress? Ghost? Medium? Substack? Webflow? Jekyll?

Capturing everything with Drafts

My first piece of advice to people who want to get more organized is: Write. It. Down. Everything. Your brain is a sieve; you think you'll remember, and then you won't. Sometimes you'll remember that there's something you're supposed to remember but you're not sure what it is, other times

Positive-sum does not necessarily mean win-win

Epistemic status: I think this is right but it's surprisingly hard to find clarification on this so I could be missing something Positive-sum interactions means the total gains outweigh the total losses - i.e., the pie gets bigger. A win-win situation means both parties come out better off -

How come firms in market economies are centrally planned internally?

Epistemic status: Thinking out loud In economics, the idealized 'free market' allows people to trade goods and services for money. The claim is that the laws of supply and demand determine prices in a decentralized way, leading to an efficient allocation of resources without the oversight of a central planner

Lesiak Family History

While my mum was sick, she put together a document with research on our family history. The original is here, and I've reposted it below. Jozef Lesiak and Regina Michon: A Family HistoryIntroductionThis is the story of how my parents came to live in England. It is a part of

How to throw a party

Invite more people than you think you need / can accommodate. Many won't be available, and many will drop out at the last minute. Parties feel way more lively when there are slightly more people than can comfortably fit in the space. Have background music on. You could create a playlist
