Friend once asked me, "What if thoughts had Fourier transforms?"

I've been wondering what the frequency domain representation of thinking would/could look like ever since.

memexy··on PG: The biggest source of stress for me at YC was running HN
I merely outlined what I would want if I was a moderator. I would rather receive email with statistical analysis than be compared to Hitler and Stalin without any data to back it up. It would be way funnier if someone proved statistically that I was Hitler and Stalin at the same time. They'd have to go through a lot of trouble to actually do that and if they managed to do so then that would be some high art.

Any complaint without data to back it up would be thrown in the trash pile.

In any case. It's a worthwhile experiment to try because it can't make your life worse. I can't really imagine anything worse than being compared to Hitler and Stalin especially if all that person is doing is just venting their anger. I'd want to avoid being the target of that anger and I would require mathematical analysis from anyone that claimed to be justifiably angry to show the actual justification for their anger. Without data you will continue to get hate mail that's nothing more than people making up a story to justify their own anger. And you have already noticed the personal narrative angle so I'm not telling you anything new here. The data takes away the "personal" part of the narrative which I think is an improvement.

memexy··on PG: The biggest source of stress for me at YC was running HN
Yes. That's what I mean. If there is an API then we can use mathematical models to answer questions about bias or lack thereof.

I also don't think that it's possible to have any forum without bias so the data I'm certain will indicate bias but at least it will be transparent and obvious so people can point to actual data to make their case one way or the other. It's hard to improve a situation if there is no data to point to and argue about. Without data people just tell stories about whatever makes the most sense from whatever sparse data they have managed to reverse engineer from personal observations.

memexy··on PG: The biggest source of stress for me at YC was running HN
I think there is a solution to this problem. If moderator decisions are made and recorded publicly then the data can at least be analyzed objectively. If there is indeed a bias then someone should be able to sit down and do the statistical analysis and show that "Yes, X type of stories / comments are more consistently flagged / removed / downvoted / etc." or "No, there is actually no bias in this instance".

I think there is contention right now because moderator decisions are opaque so people come up with their own narratives. Without actual data there is no way to tell what type of bias exists and why so it's easy to make up a personal narrative that is not backed with any actual data.

User flagging is also currently opaque and a similar argument applies. If I have to provide a reason for why I flagged something and will know that my name will be publicly associated with which items I've flagged then I will be much more careful. Right now, flagging anything is consequence free because it is opaque.

> What can be known in a system without rigor? That’s the question to make rigorous, I think.

Who is working on making that rigorous?

memexy··on The Case for Causal AI
Thanks.
memexy··on The Case for Causal AI
Interesting. I wonder if someone has tried to combine the two. I guess modern deep reinforcement learning is one such combination because it combines feedback (reinforcement) and probabilistic descriptions but maybe there are other interesting combinations of probability, causality, and feedback.

I think adding "Most Favorited" would create a popularity contest and people would start looking for ways to game the system. I don't think favorites should have metrics associated with them because as soon as metrics are introduced people will try to optimize them.

Now that I know comments can be favorited I plan to bookmark comments that include useful reference information on topics I find interesting. Adding counters for how many times the comment was favorited wouldn't really help me with that use case because I doubt anyone else cares about collecting useful references so my favorites would never make it to the "most favorited" list. I personally don't care if I make it to the list or not but I'm certain some people would care and they would go around and start playing a popularity contest instead of looking for ways to favorite information that would be useful to them.

memexy··on The Case for Causal AI
But why is that a causal explanation? If I can write down a simulation of planetary motion then that doesn't necessarily explain the causal mechanism behind why the planets actually move. In fact, there are simulations for planetary motion and none of them are causal explanations because they don't actually move the planets.

memexy··on The Case for Causal AI
The article outlines two approaches to causal AI

> There are two approaches to causal AI that are based on long-known principles: the potential outcomes framework and causal graph models. Both approaches make it possible to test the effects of a potential intervention using real-world data. What makes them AI are the powerful underlying algorithms used to reveal the causal patterns in large data sets. But they differ in the number of potential causes that they can test for.

Does anyone have references and tutorials for either approach?

memexy··on The Case for Causal AI
How does having a program / algorithm and checking it on various input values help with understanding causality?
memexy··on The Case for Causal AI
I guess it's tricky because the real world is full of feedback loops. If you want a causal model for fake news then your model needs to include some representation of incentives for ad revenue and clickbait. How does the causal inference framework handle feedback loops?

> I am sorry that you consider genuine attempts to get real answers to be trolling with no explanation as to twhy.

That's called shifting the blame because you're shifting the responsibility and consequences of your actions onto someone else. That is not how one begins an apology. An apology begins as "I am sorry. I will reflect and consider the feedback given and do better next time. Please feel free to give further feedback if you feel like it and I will consider it and improve my behavior".

I just visited the web page and saw the following message

> Internet Explorer not supported

I'm using firefox. It's better to perform browser detection and show the message if you detect that I'm actually using internet explorer. Otherwise it seems like something is wrong with my browser.

memexy··on Transcribe videos into articles. Does it make sense?
I think this is useful but do you have examples and tutorials for how to use it? If you write some blog posts and tutorials for how and why this tool is useful then you will increase the chances that people will use it and get value out of it.

> Look up the definition of dog whistles then, and discover they mean 'talking in coded language that means one thing to an outside audience and another to the inner circle'.

I wasn't pretending. You said what I described is called a "dog whistle". I have no problem with using that phrase.

memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
My point about emotionally charged language is that it's deceptive. It's a trick some people use the draw in the reader and get them to identify with the writer instead of the argument they're making. So when I see emotionally charged language I rewrite it in my mind to use neutral words so that I can see without emotional bias what argument the writer is making and reason about it objectively. Emotionally charged language is a sophistic device, it's used to obscure and confuse instead of enlighten.
memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
It's good to know I re-invented a concept that had been in politics for over a decade. Independent discoveries are always fun. I was just making observations but it's good to know what I observed is called dog whistling. So that's a correct assessment then. Scott's writing is full of dog whistles.

Which part of my statement about being trained in the human psyche was incorrect? Also, I didn't ask about your credentials and they're irrelevant to whatever point you're trying to make. I have a graduate degree in math. Have we dispensed with the credentials now?
memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
So then you weren't asking the question in good faith. When I asked you to clarify you dodged the question. I wouldn't ask if I knew, I asked because I didn't know what you were referring to.

If you want me to talk to you then make a direct point instead of confused remarks about what I know and don't know and conversations I had with other people that were unrelated to you.

memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
Ok. That's a reasonable answer and I recommend assuming good faith next time and not trolling.

> "I don't know what HBD is, care to explain?"

> Yup, pretty much.

How do you propose I respond to your answer? I asked for clarification and you replied with a troll response. How would you respond if I did the same?

I don't know what HBD is, care to explain?

> As for unfalsifiable, you claim there are dog whistles in every second sentence SA writes, and dog whistles are, by definition, unfalsifiable. You can claim anyone can see it if they look critically enough because if someone suggests they have looked critically and found nothing, you can simply claim they didn't do it right and mosey on. Dog whistles are also, by the way, fundamentally incompatible with the principle of good faith you claim to want to prosper. It's an interesting conceit, I'll give you that.

I don't know what a "dog whistle" is or what it's used for. I explained exactly what I meant by "coded" and I made a point about emotionally charged language by rewriting quoted texts to demonstrate good writing vs bad writing.

It's all clearly stated in all my posts. You are welcome to actually quote me and demonstrate directly instead of mis-directing and mis-characterizing what I said / wrote as being a "dog whistle".

memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
I don't know what critical theory is and what it is used for. I use basic reasoning and back up what I say. I used the word critical as in "critical thinking" (unrelated to any actual academic theory of criticality). It's quite simple really. I'm not motivated to make a point other than clarify my own reasoning and I expect the same in return. When someone doesn't return the favor and act in kind then I assume they're operating in bad faith and they have no intention of making an actual argument to clarify but instead they seek to obscure and confuse.

You have demonstrated several times and very clearly you were not interested in a reasoned argument even though I gave you the benefit of the doubt by outlining what I thought and engaged every one of your examples in good faith. You did no such thing and went out of your way to shape and bias the discourse in your favor. So I'm no longer interested in arguing with you or making any more attempts to clarify my reasoning.

If you want to engage further then you can reach me by email or on keybase. I'm no longer interested in being a prop for your performance in front of a group.

memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
Don't apologize. Stop using such tactics. I already pointed out what you did, how you did it, and why it was disingenuous. If you were sincere you would not have quoted me out of context, you would not have tried to bias the group opinion, and you would not have shifted the blame as you are doing now.

You should just stop because you are no longer making any points.

memexy··on Slate Star Codex and Silicon Valley’s War Against the Media
Yes, thanks for pointing it out. Both types of professionals receive training in understanding the human psyche so my point remains unchanged

> A psychiatrist is a physician who specializes in psychiatry, the branch of medicine devoted to the diagnosis, prevention, study, and treatment of mental disorders. Psychiatrists are medical doctors, unlike psychologists, and must evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments, or strictly psychiatric. A psychiatrist usually works as the clinical leader of the multi-disciplinary team, which may comprise psychologists, social workers, occupational therapists, and nursing staff. Psychiatrists have broad training in a bio-psycho-social approach to assessment and management of mental illness.

> A psychologist is a person who studies normal and abnormal mental states, perceptual, cognitive, emotional, and social processes and behavior by experimenting with, and observing, interpreting, and recording how individuals relate to one another and to their environments.
