π seems like half the size it should be

That one you found out already, it would make it much more consistent with how similar constants are used.

The gravitational constant looks like off by a factor of 4π

Not sure what you mean. Do you mean when comparing the equation for gravitational force to the electric force? Or do you mean when looking at the 'intuitive' way of writing the differential equation

$\\nabla g = \\rho$?

In either case it seems that the choice of 4π is arbitrary on one equation or the other. For example choosing Gaussian units introduces a 4π in the electrical equation and makes it look more like the gravitational equation.

cosine seems more primitive than sine

They seem equally primitive by

$sin^2 x \+ cos^2 x = 1$

and

$sin\(x\$%20=%20cos(x%20-%20\pi/2))

The Riemann Zeta function ζ(s) negates s for reasons beyond me

It doesn't according to Wikipedia

The Gamma function has this -1 I don't understand

I haven't read up on that so I don't really know. Seems arbitrary to me too.

[Seperate post, because it is a seperate point]

I wonder how a "rational" funding system would look like if an economist designed it. The expression "where researchers see the most potential for a breakthrough" under the constraint of competition over limited resources just screams "market mechanism" to me.

Comment by metus on LINK: Diseases not sufficiently researched · 2015-01-17T16:53:33.880Z · score: 3 (5 votes) · LW · GW

It seems to me that research funding is surprisingly well calibrated with a bias for infectous diseases as opposed to what I as an amateur would call "structural failure" collecting ischemic heart disease, stroke, injury and so on.

Looking at the "overfunded" category the worst offenders are HIV and cancer. I suppose cancer research is overfunded because people donate to causes their loved ones suffered and cancer tends to kill old people with a lot of money. But I have no good explanation for the overfunding of HIV which is a completely preventable disease on the personal level by using a condom and refraining from using IV drugs. BTW, the most successful HIV reduction programs give out free needles and condoms, reducing the need for medical treatment and of course human suffering in the first place.

Looking at the "underfunded" category we have injury, ischemic heart disease, COPD, depression, stroke. Injury is something that disproportionally affects poorer people, so I use the reverse reasoning to cancer. I have no good explanation for the underfunding of the other diseases here, except for maybe depression which has a bit of a stigma to it. At best I'd guess that heart attack and stroke do not have the spectacular, drawn out suffering like cancer and HIV treatment have.

You very probably have not all recommended insurances in your country of residence or your mandatory insurance doesn't cover everything you'd want it to cover. Same goes for savings, you don't save enough for old age and emergencies. Basically if at some point you would have had to do something to prepare for the future, you didn't do it.

The short version about insurance is this: Never insure anything where you can go "damn it" and pay in cash, the same rule goes for deductibles. On the reverse, insure anything that you absolutely have to pay for and would financially ruin you. Some possible areas are your house, liability insurance and health care cost. Google "necessary insurance" or similar.

The short version about savings retirement plans is this: Use google to find out if your government provides sufficient provisions for retirement, if you plan on retiring at all. If not, look for ways to provide for old age and/or invest money, the sooner you start, the better. Hold about three months worth of living expenses in the most liquid form possible to cover emergencies. To ensure saving, order your bank to transfer a set amount of cash every month to a seperate bank account which you can not access on the go.

I am not going to start a lengthy discussion on this subject as this is not the place for it, so please do not read the lack of any further answers as anything else than the statemet above. That being said ...

I am not completely sold on the premise that all human lives are equal which puts the whole idea of a cheaper saved life in question. I am not donating out of a moral imperative but personal preference so my donations exhibit decreasing marginal utility making diversification a necessity. And finally I have generally massive skepticism towards anything and anyone that claims to solve a huge, long standing problem like poverty just like the EA movement tends to do.

This is the rough sketch of my reservations. I will not discuss it further here but I am willing to discuss it in a more appropriate place, like a seperate thread or the open thread.

Personally it sems that number of commits is a metric too easy to game. If you generally are honest with yourself, keep it, but I wouldn't use it if I were to set a goal for a group of students. Another metric that is less easy to game on a personal level is time spent with your programming environment open, which is effective if you tend to either not start programming or stop prematurely. Finally the ideal metric is to have a set of features or a certain output you want to achieve and have that as a goal with the caveat that these goals tend to be too hard to achieve in the mean time.

So overall, I'd recommend time spent programming as a weekly goal and a final product as an overarching goal with the explicit option of re-negotiation.

Great list! Hope you don't mind a couple of questions.

Thanks! There would be little point in posting to a discussion board if I wasn't expecting discussion.

Any particular reason to donate to Wikipedia? I ask because I just read this interesting article about Wikimedia donations that was posted on the FB EA thread a few days ago.

Until a few minutes ago I thought that people would on average not donate enough to Wikipedia enough. Actually, my thought was more like "Wikipedia was so useful in the past and I expect it to be useful in the future too, so I could donate a small amount to make up for my use." But I am revising that thought as we speak. The larger point anyhow was to signal that I am not completely sold on effective altruism and might also donate to the Red Cross or so.

Also, how many applications per month?

I have until the end of this year to decide. A modest goal would be one per week, but it would be way more effective if I make the rate dependent on time and domain. So let's say - and let me say that this won't be the final number - one per week for stuff in industry that is not seasonal and an adjusted number for seasonal stuff.

My list of goals, nice habits to have and general goodness tends to grow in length instead of shrinking for various reasons but I can make progress anyhow in implementing it. Also I know that having way too many goals at once is harmful, so here's the obvious caveat: This is a general list and brainstorming so far, with no real plan for realiable implementation, so take the goals, the length of the list and the commentary with the proverbial grain of salt. (Legend: "I vow" is certain, "I will" actually means "maybe")

• Charity: There has been a delay in forming my contract for my student's job and thus also a delay in payment, which made me think about money a lot more than usual. Since for various reasons my cashflow will improve I hereby vow to donate 1% of my income below the taxation threshold and 10% of any income beyond that to a mix of GiveWell, CFAR, MIRI and Wikipedia of my choosing.

• Health and charity: The weird case where self-interest and the public interest coincide applies for three things I have in mind

• I will donate blood at least once in 2005. Of course I'll donate 10% of the remuneration I get.
• I will get all my vaccinations up-to-date and take any additional as recommended by my physician. Maybe the payment from above will subsidise a shot not covered by insurance. One prick for another.
• I will take a course and certification in first aid. It might just be one of my dearest people I can help or just the occasional stranger.
• Education: No university and no school can offer comprehensive education, it has to come from many sources.

• I tried audiobooks via Audible for the first time less than a month ago and I was amazed. At 10€ per audiobook it is quite a bargain and ideal for any non-fiction book with low information density like biographies. So I will listen through at least one audiobook per month, totaling twelve (12) books consumed in 2015.
• Though this will happen at university, it still gets to the same heading. I will start learning Spanish and get at least to A1 level as I am currently pre-occupied learning Russian and developing a general love for languages.
• Speaking of learning languages, as this is very fact-heavy and I start seeing the benefits of SRS, I will use Anki every single day instead of clusters of ten interspersed with pauses of a couple of days.
• Travel: This might just as well put this under the education heading, but it deserves its own spot. I will travel to at least one country I have not yet set foot in, alone. Since I live in Germany, the bar is relatively low, but this is one goal that tends to fuel itself.

• Interviewing: I will send out applications for part-time jobs, internships and stipends. Since I can control the material I send but not the answers I receive, the goal is set to the former. For far too long I have ignored the usual advice of getting at least one of each in internships, stipends, part-time-jobs and maybe a year/half-year abroad so I am looking for ways to fix that. The most obvious is to send out applications like crazy. This obviously ties into the points education and travel.

Some ideas I had before but I am unsure of in the face of total workload are to subscribe to a higher quality publication like the Economist and read at least one article every week or to read at least one book per month in addition to the audiobooks from above.

Reduced consumption of animal products, more specifically meat should help my health and both my purse and the global poor through reduced food prices.

I want to open up the debate again whether to split donations or to concentrate them in one place.

One camp insists on donating all your money to a single charity with the highest current marginal effectiveness. The other camp claims that you should split donations for various reasons ranging from concerns like "if everyone thought like this" to "don't put all your eggs in one basket." My position is firmly in the second camp as it seems to me obvious that you should split your donations just as you split your investments, because of risk.

But it is not obvious at all. If a utility function is concave risk aversion arises completely naturally and with it all the associated theory of how to avoid unnecessary risk. Utilitarians however seem to consider it natural that the moral utility function is completely linear in the number of people or QALYs or any other measure of human well-being. Is there any theoretical reason risk-aversion can arise if a utility function is completely linear in the way described before?

In the same vein, there seems to be no theoretical reason for having time preference in a certain world. So if we agree that we should invest our donations and donate them later it seems like there is no reason to actually donate them at any time since at any such time we could follow the same reasoning and push the donation even further. Is the conlcusion then to either donate now or not at all? Or should the answer be way more complicated involving average and local economic growth and thus the impact of money donated now or later?

Let the perfect not be the enemy of the good, but this rabbit hole seems to go deeper and deeper.

This is for the people versed in international and tax law.

By a ruling of the ECJ all tax-payers in the EU can deduct charitable donations to any organisation within the EU from their taxes. In Germany at least this means that the charitability has to be certified by the German authorities. The usual process here is that a legal entity wishing to accept tax-deductible donations has to document how their funds are used and can then issue certificates to donors which then document the tax-deductibility of their donations.

Which leads to a couple of ideas and questions:

1. It is obvious then that to receive tax-deductible donations in principle necessitates exactly one legal seat in any of the EU member states. This opens up donations from potentially 500 million people in the largest economic zone of the world. Does charitability have to be proven in every one of the currently 28 member states or is there an easier way to do this, e.g. by some sort of transitivity? Is it possible to get the usual certification at all or does charitability have to be proven for each and every one of the donations?

2. Is this process specific to Germany or do other EU member states recognise charitable organisations from other member states by default such as Ireland and United Kingdom? How do medium sized organisations solve the problem of receiving tax-deductible donations, do they just found a bunch of subsidaries?

3. Assuming that the situation is maximally bleak with regard of tax deductibility, would it be useful to lobby for reform at the level of the EU to make it way easier to donate from any member state to any legal entity in any other member? Or is the marginal unit of money better spent elsewhere?

Considering the tax-load in the EU and the potential wealth available for donations a lot of thought should be given to these kind of things.

I have a couple more thoughts on the whole matter of extracting more donations, if anyone is interested.
