Comment by Gunnar_Zarncke on Young kids catching COVID: how much to worry? · 2021-04-21T06:34:59.454Z · LW · GW

Overall, this sounds a lot like flu side-effects:,failure%2C%20asthma%2C%20or%20diabetes. 

I'm not saying "it's the flu". I'm saying that if Covid becomes another flu-like childhood disease, as Scott Alexander predicts, then we should expect comparable long-term effects. The question might be how much that changes the baseline of such conditions overall.

That's particularly why I'm hoping to get this into the groundwater so it's seen as something that you might just do without it being a big deal that distracts everyone. 

Seems like you agree and have an intuition when and when not to use meta. Do you know of any systematic treatment of this boundary?

Comment by Gunnar_Zarncke on Iterated Trust Kickstarters · 2021-04-20T22:33:57.763Z · LW · GW

I am wondering about a failure mode in applying this advice (and other advice of this type): While trying to apply it going to the meta-level and explaining what the goal is. For example saying: "Let's try trust-kickstarters" and linking to this post. Using the meta-level may disrupt the object-level process and should probably be avoided.

Epistemic status: I have not read about this communication norm on LW or elsewhere but it has been brought to my attention a while ago and seems to be pretty standard in practice. It doesn't seem to be related to high-context vs. low-context communication (See e.g. Decoupling vs Contextualising Norms or Culture Map).

Comment by Gunnar_Zarncke on Anger · 2021-04-19T06:18:12.486Z · LW · GW

We seem to mutually misidentify anger and hate. That is surprising. Emotions are usually assumed to be universal. Could be cultural. I looked it up and there found this research question: 

Human Emotions: Universal or Culture‐Specific? (PDF)

Anna Wierzbicka has made an effort to decompose this into fundamental building blocks:

Emotions Across Languages and Cultures: Diversity and Universals

I have not yet fully read it but this seems like a program worthy to communicate wider.

Comment by Gunnar_Zarncke on Anger · 2021-04-19T05:58:26.216Z · LW · GW

I like the idea of making emotions continuous or a spectrum but I don't think a single linear one will do. 

for example, anger can feel good - if it works (I can't say that from personal experience so much as from observation from kids).  

Comment by Gunnar_Zarncke on Anger · 2021-04-18T19:23:31.794Z · LW · GW

Except that, if I am alone with the person, the target will eventually become me no matter what I do.

I don't know what you do but I might have an idea why you become the target (because this happens to me too): You seem to be the type of person who has their own ideas, own plans, and are not easily influenced or persuaded. For some - maybe many people - ramping up emotion is one (unconscious) way to make you (or other people) understand the urgency or distress they are in. If you ignore or otherwise do not respond or acknowledge other people's stress you make it worse for them. You may not have an obligation to do something about it but you also shouldn't be surprised if it happens.

Do you think this might relate to your experience?

Comment by Gunnar_Zarncke on Anger · 2021-04-18T19:09:26.511Z · LW · GW

I think you are confusing anger with hate.

Like all emotions, anger is adaptive - though it may have been more so in the ancestral environment. Even today anger tells you something. Quick google:  

Hate was presumably also adaptive but I think its purpose is mostly lost in modern society. There I agree that it amounts to useless destruction.

Comment by Gunnar_Zarncke on Dark Matters · 2021-04-06T13:42:49.940Z · LW · GW

Thank you. The multipole moment chart is cited frequently and I was always wondering what it would look like in counterfactual worlds without DM. Therefore I am especially grateful for your explanations:

The positioning of the first peak tells you about the curvature of the universe. [...] Having different amounts of ordinary atomic matter vs dark matter early on in the universe produces different characteristic patterns in the spectrum, with ordinary atomic matter tending to enhance the even-numbered peaks, and dark matter tending to enhance the odd-numbered ones.

Can you provide a link to read up further on this? Preferably not a summary but the actual research article.

Comment by Gunnar_Zarncke on Predictive Coding has been Unified with Backpropagation · 2021-04-05T15:25:28.024Z · LW · GW

Well, another advantage of the BNN is of course the high parallelism. But that doesn't change the computational cost (number of FLOPS required), it just spreads it out in parallel.  

Comment by Gunnar_Zarncke on Predictive Coding has been Unified with Backpropagation · 2021-04-04T20:33:21.942Z · LW · GW

Partly, yes. But partly the computation could be the cheap part compared to the thing it's trading off against (ability to grow, fault tolerance, ...). It is also possible that the brains architecture allows it to include a wider range of inputs that might not be able to model with back-prod (or not efficiently so).  

Comment by Gunnar_Zarncke on [deleted post] 2021-04-04T19:04:04.532Z

A while ago I made the claim that

Arguments for the singularity are also (weak) arguments for theism.

Note that I have updated since a bit on some of the points but not flipping the direction.  

Comment by Gunnar_Zarncke on Predictive Coding has been Unified with Backpropagation · 2021-04-04T00:00:19.272Z · LW · GW

On page 8 at the end of section 4.1:

Due to the need to iterate the vs until convergence, the predictive coding network had roughly a 100x greater computational cost than the backprop network.

This seems to imply that artificial NNs are 100x more computationally efficient (at the cost of not being able to grow and probably lower fault tolerance etc.). Still, I'm updating to simulating a brain requiring much less CPU than the neurons in the brain would indicate. 

Comment by Gunnar_Zarncke on Forcing yourself to keep your identity small is self-harm · 2021-04-03T23:21:06.397Z · LW · GW

I am unhappy with what I perceive as a strong position against 'keep your identity small' - which I see as a very useful heuristic. I have re-read Paul's (pretty short) post and I agree that he does not discuss any downsides or over-applying the rule. I wish you had put your last paragraph first. That would have made it much more balanced.

Comment by Gunnar_Zarncke on Hardware is already ready for the singularity. Algorithm knowledge is the only barrier. · 2021-03-31T23:25:05.553Z · LW · GW

I understand his point is not that we have enough CPU and RAM to simulate a human brain. We do not. His point seems to be that the observable memory capacity of the human brain is on the order of TB to PB. He doesn't go too deep into the compute part but the analogy with self-driving cars seems suitable. After all quite a big part of the brain is devoted to image processing and object detection. I think it is not inconceivable that there are better algorithms than what the brain has to make do with for the intelligence part.

Comment by Gunnar_Zarncke on Goldfish Reading · 2021-03-31T23:07:48.201Z · LW · GW

That sounds quite a bit like what I do. When I encounter an insight in an article that I want to keep I create an Anki card from it. Here is the latest one that came up in my Anki:

Q: Which people who say that they want to change actually will do?

A: An observation: People who blame a part of themselves for a failure do not change. If someone says "I've got a terrible temper", he will still hit. If he says "I hit my girlfriend", he might stop. If someone says "I have shitty executive function", he will still be late. If he says "I broke my promise", he might change. 

And for this article I will create:

Q: Goldfish Reading is

A: reading text without trying to fully understand (or memorize) all of it at once but focus on the key parts of it (and optionally making Anki cards out of it). A bit like this Anki deck but with more cards.

About the carrots: I have seen warnings that excessive carrot consumption can show on the skin but I have a friend who also snacks a lot of carrots and it is not showing. I think the risk is very low and easy to fix. 

Comment by Gunnar_Zarncke on Calibrating Adequate Food Consumption · 2021-03-28T21:47:21.958Z · LW · GW

Can you give some examples of what your meals look like?

Comment by Gunnar_Zarncke on Calibrating Adequate Food Consumption · 2021-03-27T00:26:06.113Z · LW · GW

I will start with more details about our soup parties (or how they were before Covid19): It is a bit of put-luck: It is common to bring some snacks, fruits, or sweets. But the main dish is almost always a vegetable soup, which we prepare together. There are frequently vegetarians, so we mostly have two pots, one with meatballs and one without. Rice and noodles are usually provided, and some of the kids prefer the noodles without anything else - maybe just some of the liquid of the soup without the vegetables. And that is OK. Vegetable soup is an exaggeration. A big part is potato and with all the rice and noodles it is a lot of carbohydrates. And that is OK. After the soup, the sweets and snacks are opened (the kids mostly try to get them before the soup). Sweets and snacks means chocolate, gummi bears, chips, and stuff like that. For a party that is OK. And parties like this happen every other week. We drink fruit juices, water, and tea, rarely coffee. It is very rare to drink beer or wine, but I would consider one beer (0.33l) per adult OK.

One thing that I think is OK for my personal diet is my relatively high sugar intake. Over three months, I measured my sugar intake from sweets (sugar from all other food, e.g., bread, cereals not included), and it averages to about 100g per day. I wouldn't recommend this to others, but my metabolism seems to deal with it fine (no overweight), and the same holds for most of my relatives. I have experimented a bit with my sugar craving, and I can reduce it with some tricks, but as that doesn't seem to have much of an impact, I'm OK with it. I do try to buy sweets and chocolates with less than 40% sugar.

Scott says

And while he doesn't give a more detailed explanation I think it is clear that humans are not Bayesian but our brains use some kind of hack or approximation and that it's plausible that trapped priors can happen.

Comment by Gunnar_Zarncke on Sharing a Car · 2021-03-18T01:22:12.590Z · LW · GW

I think you are overthinking it. We (that is my ex-wife and I) used to car-share a car with my sister and her family but it turned out that a growing family and other considerations led to this being temporary in the end. This could be the case for you too and then not worth the effort you seem to go to.

For what it's worth: We cycled thru 5 cars since then. Always used cars (of monotonically larger size) and except for the last one always < 4000€.

Comment by Gunnar_Zarncke on [Prediction] The Consequences of Radical Reform · 2021-03-10T00:12:39.097Z · LW · GW

It's funny: I also guessed 70%. Specifically, I guessed that 70% of the places benefited which is not the same as lsusr's prediction but the same as Ben's. I didn't think of a confidence in this estimate. For lack of time, I didn't do an elaborate analysis but followed the intuition that when there are many data points some are bound to benefit and some not to. As the reforms generally seem to be seen as positive I rounded up to 70%. 

I think lsusr's point that measuring success by GDP obscures the local effects and esp. the GDP/person might tell a different story.

I always preferred raw vegetables though not all of them. It seems to be common in my extended family to serve vegetables cut in slices or sticks for ready snacking. Many in my circle of friends do so too. Sometimes, more or less spicy dips are offered (which I don't like but which is easily ignored). My kids still ignore them mostly. Apples served the same way are gone quickly though.

11. Will the scientific consensus end up being that hydroxychloroquine was significantly effective?

UpToDate, the closest thing to a canonical medical recommendation site, currently says: "We suggest not using hydroxychloroquine or chloroquine in hospitalized patients given the lack of clear benefit and potential for toxicity. In June 2020, the US FDA revoked its emergency use authorization for these agents in patients with severe COVID-19, noting that the known and potential benefits no longer outweighed the known and potential risks". False. 

Comment by Gunnar_Zarncke on On the Nature of Reputation · 2021-02-20T14:55:19.093Z · LW · GW

An important concept laid out well with real-world examples. I like it.

You say that splitting is not possible as you need a new name that has to be filled with new trust. One thing I have learned from some professional managers and people who seem good at naming things: A good name takes an existing well-known name and adds a bit to it. Half of the quality of a name is the right name to build on top of. That is why there are so many "X 2.0" and "X Plus". And with your model, it becomes clear why: In these cases, you do take over (some) of the reputation to the new brand.

PS. You really should let someone spell-check your text or run it thru a grammar checker.
