A new and more useful way to rate how much you like something (e.g. food, experiences)

Usually when you ask someone to rate how ‘good’ something, people will rate it out of 0 to 10. For example, if you ask someone ‘how much did you enjoy that food?’, people will give a number from 0 to 10 where 0 means it was bad and 10 means it was perfect. This is fine in theory, but in practice I think it isn’t the best scale to use.

I prefer to use a scale of -10 to 10 where 0 is the neutral point. 0 means that you would be equally happy experiencing vs not experiencing that food or thing. Anything negative means you would have rather not eaten it, and anything positive means you are glad you ate it.

The benefit of using this scale is that it makes it clear whether the experience was positive or negative. With the scale of 0 to 10, the halfway point of 5 should in theory mean a neutral point, but the scale doesn’t seem to get used that way all of the time. Sometimes it seems like people use 3 to mean ‘it was a little bit good’. There also seems to be asymmetry between the peak of 10 and the trough of 0. 10 usually means ‘perfect’ while 0 usually means ‘mediocre to below average’. -10 to 10 removes this confusion.

Another example is for watching a movie. If I’m rating a movie, a negative score means I would rather have done something else (some average, mundane activity for example) than watch that movie in hindsight. I think this is more useful when someone is considering whether or not to watch a movie and wants your thoughts. Assuming they have similar tastes to you, a negative score clearly implies that they should not watch the movie.

Why am I writing about this? Who cares?

Well, I think communication is important, and this could be a tool to improve communication.

There it goes, the very last tree [environmental poem/art]

My mum Janine Dello and I made this together (I wrote the poem, she put everything together) for a fundraiser event to support artist studios.

There it goes, the very last tree. 

This will make a great spot for our new factory. 

The koala watched from the top of the hill, 

As foul fluid from a dozer began to spill. 

The bear felt despair, but no longer cared, 

With their family gone they were no longer scared. 

It wasn’t their fault you see, 

That’s just the way they were raised to be. 

Their society tells them that this is normal, 

And they all desperately want to be conformal. 

To clear the land for the sake of a steak, 

This practice is humanity’s greatest mistake.  

To take a native’s home to breed others, 

Then take the children away from their mothers. 

If this is the way of the human race, 

Then this koala hopes that they will be replaced.

The risks of a raw vegan diet

Once when someone found out I was vegan they asked me: Don’t you miss cooked food?

Some people conflate a raw vegan diet with veganism in general, and I know some people who follow a raw vegan diet over simply being vegan for health reasons. I’m quite critical of the claims made by proponents of a raw food diet, and wanted to make a comment on it. If you disagree, please let me know ASAP so I can change my mind.

One of the core claims of the raw food movement is that cooking destroys some of the enzymes and nutrients in food, but there doesn’t seem to be any evidence behind this. Stomach acid destroys most of the enzymes in food anyway, and cooking food can often have a positive effect. For some examples:

Cooking tomatoes increases by five-fold the bioavailabilty of the antioxidant lycopene.

Cooking foods with beta-carotene (like squash and sweet potatoes) helps release their nutrients and makes them more absorbable.

Vegetables in the cruciferous vegetables family (kale, broccoli, cauliflower, cabbage, Brussel sprouts) contain goitrogen compounds, which in excess can contribute to hypothyroidism – but they are mostly deactivated by heat.

A 100 percent raw plant-based diet has been associated with a lower bone mass (though note this is from 1 study with a not very impressive sample size).

I’d say the only saving grace of a raw food (vegan) diet is that it forces you to consume a whole foods plant-based diet, which is more nutrient and less calorie dense than say a diet with many processed foods. There is nothing wrong with a processed food per se, but they typically have fewer nutrients and more calories, which can be a problem.

Of course, for me veganism has nothing to do with health. I happen to agree that avoiding animal products and eating more plant-based whole foods are generally beneficial for health, but if it were the opposite, I wouldn’t start including animal products in my diet for the same reason I wouldn’t start including human products in my diet if it turned out that were a little healthier.

Update on my blog, podcast and Youtube channel

I’ve been a little quiet in the last few months as I’m in the final steps of completing my PhD. I’m finalising my thesis as we speak, and should be submitting it within the next month or two. Once I do, I’m excited to get back to making more blog posts and Youtube videos, and rebooting the Morality is Hard podcast.

I just want to thank everyone for their support so far. I recently hit 550 subscribers on Youtube, which is just incredible. My video on why I will never have children has reached 6,600 views, which makes it by far the most viewed piece of content I have ever made (more views than my thesis will likely ever reach, sadly!). Message received – antinatalism is a topic of interest to many of you. I will be doing more on this in the future. I have been overwhelmed by your support, and it’s clear that many people feel alone in their views on this – surrounded by a society where breeding is seen as the norm, and anything else is seen as odd.

In other plans, I will be doing a collaboration video on antinatalism in the near future, and I have some other collaborations lined up with other Youtubers to talk about ethics and philosophy. You can expect some videos on my research from my PhD, including the pros and cons of developing space technology, off-Earth mining and space colonisation. If you have any topics you’re burning for me to cover, please do let me know.

Thank you.

Preparing for the unimaginable

How can we predict and prepare for unexpected events that we may not have even thought of yet?

I gave a talk on some of the work I do as part of my PhD and discuss how we can predict and prepare for unexpected events known as black swans.

Thanks to UNSW and the UNSOMNIA team for helping me put this together!

If anything positive comes out of COVID19, I hope it’s that we will have better disease control protocols and public health around the world – but also that we might use this unexpected event to think about how we can prepare for future unprecedented events.

A 2 metre asteroid has a 0.5% chance of hitting Earth this year

A 2 metre wide asteroid has a 1 in 200 chance of entering Earth’s atmosphere on November 2 this year. The most likely scenario is that it will blow up in the atmosphere, causing some damage at the surface.

The Chelyabinsk meteor that exploded over Russia in 2013 caused ~1,491 human injuries and some property damage (mostly shattered windows). This was 20 m wide, so we can expect less damage than that, but still some kind of damage.

There’s not much we can do about it now except monitor it to better understand up the impact probability, and where it would hit if it did.

Segue – Look at the headline and first paragraph of this Channel 7 News article.

“Astrophysicist weighs in on asteroid zooming towards earth” sounds scary, and “The National Aeronautics and Space Administration (NASA) is monitoring an asteroid that appears to be on a direct collision course with earth.” sounds like we’re a bit fucked.

Asteroid impacts are no laughing matter, and I think we should be more worried about them in general than most of the public is (you’re more likely to be killed by an asteroid than a shark), but this kind of click/scarebait in news is frustrating.

News outlets are barely held accountable for misleading or false information, let alone clickbait, and that needs to change.

Stop saying ex-vegans were definitely never vegan

This post is prompted by the recent news that Miley Cyrus is no longer vegan, which she revealed on Joe Rogan’s podcast, but is a response to the consistent trend I see of people claiming that a vegan who stops being vegan was never a vegan to begin with. I want to talk about why that doesn’t make sense.

Let’s clarify the claim people are making. It goes something like:

If someone seems to be an ethical vegan (vegan because they think animal exploitation and/or suffering is wrong), but at some point in the future they start eating animal products again, then they were never an ethical vegan to begin with, they were just plant-based (meaning they didn’t eat animal products but were never an ethical vegan).

First, I don’t think this is how human minds work. We are not perfect rational actors, and we do weird things that don’t make sense all the time. We also change our minds a lot. I think it is absolutely possible for someone to fully believe that purchasing animal products is wrong, and to later change their mind on that. Why wouldn’t it be? It’s possible to change your mind in the opposite direction (indeed, that’s how most of us became vegan). It might seem unfathomable to me to consume animal products for pleasure again, but that doesn’t mean that it’s impossible.

Someone told me that they would die before eating animal products again. I note that Cyrus said something similar. If someone says that they would die before being friends with someone of another race, but then they reject their racist ways, does that mean they were never really racist, or has their character changed?

Misinformation, pressure and a lot of other factors lead well meaning people to think and do some strange things which are against their prior values and beliefs.

I don’t know the specifics behind Cyrus’ backflip, and to be honest I don’t care, but it seems disingenuous to say that she was definitely never vegan. Maybe she actually was never an ethical vegan, and only promoted ethical vegan and animal rights messages because it suited her image. But to say this is definitely the case without proof doesn’t make sense.

Let’s say it’s impossible for someone to be an ethical vegan for 10 years and then start eating animal products again. If that were the case, there would have to be a way to tell whether someone is plant-based, not just vegan, in a way that doesn’t require the retrospective judgement. To put that another way, how can you tell that a current ‘ethical vegan’ is actually just plant-based, if they haven’t started eating animal products again?

What’s the effect of the vegan community thinking that all ex-vegans were never really vegan to begin with? I have no idea. Maybe it makes the community look dogmatic and off-putting, or maybe it encourages people to not change their mind. But I know that it just doesn’t make sense, unless there is something I’m missing.

“Do you lie awake at night worrying about volcano eruptions, asteroid impacts, global pandemics, evil robots, or nuclear warfare? Have you spared a moment to consider that there might be existential threats humans can’t even imagine? If anything positive comes out of COVID-19, it’s that we will have better disease control protocols and public health around the world – but also that we might use this unexpected event to think about how we can prepare for future unprecedented events. What can we do today to prepare for the unimaginable?”

Comments on Sam Harris’ interview with Future of Life Institute

I finally got around to listening to Sam Harris’ interview with Lucas Perry on the Future of Life Institute podcast. Overall I thought it was pretty good. I didn’t personally update on or learn much, but I enjoy listening to conversations about reducing suffering, the far future and existential/catastrophic risk.

Conversations they touched on include global priorities, existential risk, wild and farmed animal suffering, global poverty, artificial general intelligence risk and AI alignment and ethics/moral realism.

I agreed with most of what Sam said, so I won’t touch on that. I also felt like this particular instance of Sam explaining his version of moral realism to be the most clear explanation I’ve heard from him, so it’s worth catching the last 20 odd minutes for that. There were a few things however that I disagreed with Sam on, and want to briefly share why.

First is the intuition he has that there is an asymmetry between suffering and pleasure. He’s not talking about the asymmetry of the asymmetry argument put forth by David Benatar, but rather that the worst possible suffering that we could experience seems worse than the best possible pleasure we could experience could be good. To put it another way, Sam says that if you could choose to get an hour of the most blissful possible experience, followed by an hour of the most painful possible experience, most people, following their intuition, would say ‘no thanks’.

But this is just an intuition, and our intuitions aren’t always right, even when they are about our preferences. I might think that I would prefer some experience over another, but I could very well be wrong about which would actually bring me the most joy. I think it’s possible that the worst suffering could be more bad than the best pleasure is good, but I don’t take it for granted. It could be the opposite.

We can’t yet imagine just how good the best possible pleasure could be. We might be biased towards thinking suffering is worse because nature tends to make us more suffering focused through evolution (see the wild-animal suffering argument), but it needn’t be that way forever. We could hack our minds or biology as David Pearce suggests to experience less suffering and more pleasure.

Also, when ones’ life is pretty good, one might think that the 1 hour of pain followed by 1 hour of pleasure is not a trade off worth making, and maybe even for good reason – if your life is already net positive, this would be a net bad trade off. Someone experiencing unimaginable chronic pain through some disease might feel differently.

The second thing I disagreed with Sam on was his position on veganism. In particular, his position on children being vegan. He said that it was effectively a longitudinal experiment on their health that we don’t yet know the outcome of. To the extent that nutrition is by its nature a difficult science, and that we can never be completely sure of the effect of various changes to our diet on long term health, I agree.

However, we don’t completely understand the long term health outcomes of consuming animal products either. This has certainly been the status quo in western culture, but it’s not inherently obvious that the status quo is good. The unknown could be bad, or it could be good. You can have an unhealthy vegan diet, and you can have an unhealthy non-vegan diet. The pressures that parents have to not harm their children through nutrition remain the same. We hear about malnourished vegan children in the media more because of the sensationalist media bias and confirmation bias – we don’t pay attention to the hundreds of malnourished non-vegan kids because they’re either not reported or their ‘veganness’ doesn’t come in to the reporting.

Finally, some words to Sam himself. Sam you’re not a child, and yet you’re not vegan. You admit to all of the moral shortcomings of animal agriculture, and yet you partake in it. Surely if there is a peak in the moral landscape we are working our way towards, you eating animal products is not helping us get there, indeed it might be moving us away. You have even more of a responsibility to be vegan given your follower-base. You being vegan could encourage thousands of others to follow suit.
