lol, your first paragraph described exactly the discussion I had with a friend less than one month ago... and you wrote the exact question he made me.

“So you want people to sit at home all day and collect free money?”

On my mind, I had "Yes. I want this. For everyone. Not just money. I want to give everyone all the resources they need to fulfill their lives. I'm trying to discover how"

I wonder why ended up dodging the question; yes, +1 for star-manning. I like the concept.

I'm having fun exploring the subject and I would love anyone to expand on this topic, if anyone has ever explored this craziness we are seeing.

I really like the approach from Tournesol and I was wondering a way to improve the rating system.
Not only I would like to rate a video, but sometimes I would like to dispute the rating given by another user.

Suppose I am a seller on AliExpress. I have been selling a 4.8 star product for a year.
Suddenly I receive a new and rare one star rating. The rating goes like this:

"User123: I waiting the product to arrive, can't wait to see it. When it arrives I will update the rating"

This is not uncommon. A good proportion of ratings happen without any correlation to the meaning of the rating labels. Sometimes someone miss click, and sometimes the user is completely stupid and does unexpected things. A user may say that some content is unreliable while being factually incorrect.

One thing that could work is that if enough people clicked on 'dispute button' to dispute the rating given from some user, the data from that user would be considered "noise" until some debate was settled. Or we could just change the weight of his input. Maybe the user has to provide some explanation for his deviant input and his input weight would go back to normal. Otherwise few trolls could destroy the system by creating bots to steer the rating system to his preference. But it would be harder for him to justify each instance, and a user with a high proportion of ratings being disputed should raise a red flag.

On the UI provided on the white paper I can see 5 horizontal sliders. Maybe we could add optional explanations for the user to clarify why he gives "1 star importance" for this video about "very important topic". Users that give explanations for their ratings should have higher weights than users that do not provide any explanation. Maybe I could give a like on the rating+explanation from another user, updating my view on the platform and the final weight of his rating.

Open & Welcome Thread - December 2020

I believe that many people will take COVID to their relatives during Christmas and the New Year, and I'm seriously thinking about starting some campaign to make people aware that they should at least this time consider wearing a mask for the next weeks and also stop socializing without a mask during this period in order to protect their relatives during the traditional holidays. I started developing a mobile app today to be released by December 12 and another (also related to COVID) to be released by December 20, I don't know what impact this will have on people's decisions, but I'm already leaving here publicly registered so that it works as a personal incentive not to pay attention to anything else until the two apps are released.
PM me if you want to join development, I'm using KivyMD to develop the apps. The first app lets you easily record your last social gatherings, saying how many people (with and without masks) were present, when it happened, the duration (short or long), and if were indoors or outdoors. Then it says how risky is going to see your relatives on Christmas or in any other date and what you should do to mitigate the risks. There are also other things, but this is the main idea. The second one is a COVID game, aiming to influence social behavior and public discourse during pandemic, details later.

Small Habits Shape Identity: How I became someone who exercises

I haven't exercised regularly in years, and last week I started thinking about how bad the consequences can be for me. I decided to do something, I wasn't in the mood, I thought "well, I'll do 10 push-ups. Maybe it's not much, but it's better than nothing". And I made it. You said "make it ridiculously easy", and now I just made 15 push-ups. Interesting. This is really easy. And I will do it again. Just a little more on the next time.

Should students be allowed to give good teachers a bonus?

Epistemic status: babble all the way down, not pruning. But I believe my approach is better than most of other answers here.

The error from other LWers  is not separating the evaluation of lessons to the evaluation of tests.

Students should be allowed to give good teachers a bonus. For each lesson, in any moment of the lesson, the students should have the possibility to rate the teacher's performance on some metrics. Think on a mobile application that does that. Do you know when you take a ride with an Uber and immediately after finishing the ride you rate it? We should have the same possibility of rating teachers after their lessons (up until some limit, e.g., you had your lesson on Monday, you won't be able to rate it on the next month, you have until a week to rate this lesson). The teacher should be paid a bonus when he gets good scores. This bonus would be added lesson by lesson to teacher's account.

Let's say each week I have three different lessons with professors A, B and C.
Professor A gives me 2 hours lesson/week.
Professor B gives me 4 hours lesson/week.
Professor C gives me 6 hours lesson/week.

For each two hours lesson, the student gains one point to spend. So, I have 6 points to spend on spend on professors A, B, C in any way I choose to.

The professor A, I've just watched his lesson and I loved it. I give him 3 points. Professor B is good too, I like him, but I will just give him two points. Professor C is not that good teacher, but he seems to be working hard on these particular difficult topics, I'll give him one point.

On the end of the month, good teachers will be rewarded by how good their performance were on THE LESSONS. I haven't spent time thinking on a good function to convert the scores received by the teacher on this week to money, but it doesn't seem hard to create a fair one.

We should have a separate rating system for the evaluation of the tests applied by the teacher, so we could separate the feelings that appear on our heart when we compare the quality of the lessons to the difficulty of the problems posed by the professor on his test. We know when we go bad on an exam, "that's the teacher's fault". So this separate system would be more strict, asking several questions like "How difficult was this test? How many hours have you studied before doing it? The questions on the test were related to things taught on the lessons? How do you compare the difficult of the test questions to the difficult of the lessons' questions? Leave a comment about the test on the following Entry box". Obviously I haven't pruned these questions, they just arrived at my mind, but certainly there exist a very good set of questions that could let us investigate how well the teachers perform in creating tests and also reward them when we detect it.

Thinking again about the first system, it should also have some questions about the lesson. "How good the professor explains the concepts? How organized he is? Did you learn the concepts? How do you rate the difficulty of the topics this teacher is trying to explain to you? [Leave here what kind of questions you believe would improve this questionnaire]. Leave a comment about the lesson on the following Entry box".

It shouldn't be needed for a student to answer these questions to give all his points  for a teacher. But we could weight the student points by how many questions he answered. For example, if I gave you 3 points and I said why I've done this, this weighs more than a student that gives you 3 points but doesn't explain why he does that. Justified rating is worth more than unjustified rating.

1. this advantages teachers with larger classes.

Your reward function can take in consideration the number of students that participated on the lesson, the number of students the rated the professor, and also you could average the scores, I don't know, come on, you can create a function that is fair for any class size, you just have to think about what function you will use

Where does the money come from?

Diminish all salaries in x%. Now you can redistribute this money more fairly, proportional to performance.

My second-favorite teacher in undergrad was relatively unpopular because he taught very difficult classes, at least some of which were required to graduate.

That's why it is important to evaluate the LESSONS every week. And when the test comes, this is a different evaluation. This professor was unpopular due to difficult tests, not to bad lessons, right?

Most universitites have already systems where students evaluate their teachers at the end of the year and the scores do figure into administrative decisions of the university

That's the problem. At the end of the year you are evaluating the "teacher", which means

If I find the teacher a good professor and I give him +5 points, but I sucked at his tests, and I give -10 points for my bad feelings for doing bad on the test, the final evaluation of the teacher is "tis teacher is bad" == -5

If the system rates week by week, we could detect misuse of the system if we suddenly see bad lessons ratings close to the test application (right after the test, for example).

I don't think this is how market wages work. If it is known that the average teacher gets a $100 bonus, the school will offer$100 less in base pay than it would otherwise.

Maybe not right now, when the change is introduced. But in the following years, the wages will raise slower than they would otherwise, until the balance is achieved.

It doesn't seem bad to pay a little less for the average teacher with average lessons, and pay a little more for the above average teacher with above average lessons. It seems like arbitrage. You do good lessons, you earn more. Why not? And if you can now detect which teachers are much worse than average, you can fire them and get even more students that are interested in this school full of good teachers, because the bad ones can't stay

Stupid Questions October 2020

I don't think so. For example, follow these instructions:

1. Say you are a poor guy on a poor country
2. Say you luckily got a computer when you were a child
3. Say while you were studying AI, you found LW.
4. Say bad events happen to you/your family, and now you are in urgent need.

Now you can see, although most LW readers are not like this guy, this guy is among LW readers. My point is that we should financially support this guy, independently if he belongs to LW or not. I would say it is easy to help him and we have a reason to support him, and the fact he reads LW doesn't change the facts on his life. Again, although not common, we should be prepared to detect and solve this kind of unfortunate situation. At least this is something I would do if I had enough resources to help.

Stupid Questions October 2020

Why would they?

Sometimes non needy people want to help other people in need. If you were looking to maximize happiness points across the world, for example, you would gain more points helping those members in need.

Considering that LW readers are mostly rich Americans

There are non-zero members suffering financially, that's why I asked that. It would be too easy for some people here to make this number go to zero.

Stupid Questions October 2020

My question was really stupid, actually I was thinking "I would like to spend at least 200 hours on this project, but it seems I won't get any money from it, maybe I could ask LW members if they want to support it financially".
A better question is "Can I ask you money to help me to build a software that may help you?", or "it is inappropriate to ask for money on LW, the platform discourages this".

Disclaimer: I am still not sure if this is the correct question. Anyway, I am developing some helper tools, and although I won't monetize them directly, it would be good to get some money from it, because I am not the guy who has enough money to not need any money from the community anymore.
