Gleb Tsipursky

When I first started donating, I did so anonymously. My default is to be humble and avoid showing off. I didn’t want others around me to think that I have a stuffed head and hold too high an opinion of myself. I also didn’t want them to judge my giving decisions, as some may have judged them negatively.

I wish I had known back then that I could have done 

much more good by publicizing my donations and other goods deeds, such as signing the 

 to donate 10% of my income to effective charities.

Why did I change my mind about being public? Let me share a bit of my background to give you the appropriate context.

As long as I can remember, I have been interested in analyzing how and why individuals and groups evaluated their environment and made their decisions to reach their goals – rational thinking. This topic became the focus of my research as a professor at Ohio State in the history of science, studying the intersection of psychology, cognitive neuroscience, behavioral economics, and other fields.

While most of my colleagues focused on research, I grew more passionate about sharing my knowledge with others, focusing my efforts on high-quality, 

. I perceived my work as cognitive altruism, sharing my knowledge about rational thinking, and students expressed much appreciation for my focus on helping them make better decisions in their lives. Separately, I engaged in anonymous donations to causes such as poverty alleviation.

Yet over time, I realized that by teaching only in the classroom, I would have a very limited impact, since my students were only a small minority of the population I could potentially reach. I began to consult academic literature on how to spread my knowledge broadly. Through reading classics in the field of social influence such as 

, I learned a great many strategies to multiply the impact of my cognitive altruism work, as well as my charitable giving.

the value of being public about my activities.

 and subsequent research showed that our peers deeply impact our thoughts, feelings, and behaviors. We tend to evaluate ourselves based on what our peers think of us, and try to model behaviors that will cause others to have positive opinions about us. This applies not only to in-person meetings, but also 

, illustrates how we evaluate appropriate behavior based on how we see others behaving. However, 

 that people who exhibit more beneficial behaviors tend to avoid expressing themselves to those with less beneficial behaviors, resulting in overall social harm.

Learning about the importance of being public, including in online communities that reach far more people than in-person communities, especially by people engaging in socially beneficial habits, led to a deep transformation in my civic engagement. While it was not easy to overcome my shyness, I realized I had to do it if I wanted to optimize my positive impact on the world – both in cognitive altruism and in effective giving.

I shared this journey of learning and transformation with my wife, Agnes Vishnevkin, an MBA and non-profit professional. Together, we decided to co-found a nonprofit dedicated to spreading rational thinking and effective giving to a broad audience using research-based strategies for maximizing social impact, 

. Uniting with others committed to this mission, we write articles, blogs, make videos, author books, program apps, and collaborate with other organizations to share these ideas widely.

I also rely on research to make other decisions, such as my decision to take the 

 is key here – we make a decision in a state where we have the time to consider their consequences in the long term, and specifically wish to constrain the options of our future selves. That way, we can plan within a narrowed range of options and make the best possible use of the resources available to us.

Thus, I can plan to live on 90% of my income over my lifetime, and plan to decrease some of my spending in the long term so that I can 

give to charities that I believe are most effective for making the kind of impact I want to see in the world.

Knowing about the importance of publicizing my good deeds and commitments, I recognize that 

I can do much more good by sharing my decision to take the pledge with others.

 All of us have friends, and the large majority of us have social media channels and we all have the power to be public about our good deeds. You can also consider joining or creating a new 

 for effective altruism in your community. 

, letting others hear about effective altruism and motivating them to give more and more effectively.

According to the scholarly literature, by being public about our good deeds we can bring about much good in the world. Even though it may not feel as tangible as direct donations, sharing with others about our good deeds and supporting others doing so may in the end allow us to do even more good.

Why you should be public about your good deeds

If you're reading this, you may have already taken the Giving What We Can pledge. Nevertheless, we want to let you know that 

 this New Year. We are looking to get as many new people to take the pledge as possible, and we need your help. If you can persuade somebody to commit 10% of their income to effective charities, you can potentially double your impact.

Most of our society doesn't even consider the idea of pledging to give 10% to effective charities yet. So if you're someone who has taken the pledge, you've made an rare and amazing commitment. You're probably giving away thousands of pounds each year. You wouldn't be doing that unless you had a good reason, and it's probably not just because you get your name on a cool list.

Do you think all of us living safe lives in rich countries have a duty to those less fortunate? Does it bring you joy to save lives? Do you have a deep sense of empathy for people suffering around the world? Does it sadden you that our world is as broken and contains as much suffering as it does?

This New Year, think about the people in your life who might understand and share those reasons. Maybe you know someone who also cares for others or feels that they have a duty to those less fortunate, but they're currently giving to charities that are less effective than they could be. Perhaps they have a deep sense of empathy and are saddened by the suffering in the world, but they haven't yet noticed that giving 10% is a way to help. Maybe they're even giving 10% or more already, but they haven't made the public commitment of taking the pledge.

If you know anyone like that, please reach out to them. 

We want as many people as possible to join us in taking the pledge this New Year. Whatever driving passions or deeply held moral beliefs or lofty ambitions made you take the pledge, we want you to share them with people, to show them to those who need inspiring, and be extraordinarily proud of the good you do in the world.

 Here is a list of things you can do to help us inspire more people:

Six ways to double your impact this New Year's

Hauke Hillebrandt

Malaria may be the worst killer in history — some estimates suggest it has killed half of all people who have ever lived. It still kills thousands of people — mostly children — every year.

 that in 2015 alone, 438,000 people died of malaria - 292,000 of whom were children under 5 in sub-Saharan Africa.

But this map shows a surprising, and encouraging result.

The animation shows the percentage of children in Africa who had malarial fevers over the last 15 years. Dark red means 100% -- that is, all children in the area -- had at least one episode of clinical malaria within a given year. Green means 50%, and blue means that no children had a malaria fever within a given year.

Here’s another map using data for people of all ages

 — you can see the same pattern. A massive decrease in malaria cases over the last 15 years.

These maps show a clear trend — in fact, rates of malaria have halved over the past 15 years

. But why has there been such a dramatic decrease in malaria?

The reduction in malaria has been caused — in large part — by people sleeping under bednets. Green means everyone is sleeping under bednets and is protected, yellow means half of all people are protected, and red means nobody is protected from malaria.

Long lasting insecticide-treated bednets are a powerful weapon against malaria

, not only because they’re a physical barrier between mosquitoes and sleeping children — the insecticide coating kills mosquitoes, so they don’t infect other members of the family (and the village) who don’t have mosquito nets.

The data used for these animations comes from a new paper published in 

 (widely regarded as the top science journal). We already had very strong evidence that bednets prevent children from dying of malaria (and related complications like anemia) based on a meta-analysis of 22 experimental trials

But this new paper uses a “spatiotemporal Bayesian geostatistical model of bednet coverage with 27,573 georeferenced population clusters and an optimised suite of temporally dynamic environmental and sociodemographic covariates”.

In other words, this paper tells us about the bigger picture, showing that bednets are incredibly effective, not just at the level of individual villages, but at the level of whole populations. Essentially, the case that we should be distributing bednets just got even stronger.

The research suggests that anti-malarial interventions have prevented about 

Long-lasting insecticide treated bed nets

 stand out as being particularly effective — being responsible for around 68% of the malaria reduction. This means that 

bednets have prevented around 450 million cases of malaria

 over the last 15 years because of malaria interventions 

We’ve made great progress. But we’re only halfway there.

Notice that, even in 2015, there are red and yellow spots on the map. 45% of all people in Africa are still at risk of disease and death from malaria 

, because they are too poor to buy nets, 

and an additional 245 million nets are needed in the next 2 years.

Malaria is also an immense economic burden on health systems and people: since 2000, malaria treatment in sub-Saharan Africa has cost almost $300 million

. We can see the flip side of this in places in the United States, Brazil and Uganda — children born after malaria was eradicated or heavily controlled and so were not exposed to malaria during pregnancy, had substantially higher income later in life 

We urgently need to keep funding the distribution of bednets, because 

bednet distributions are one of the most cost-effective ways of preventing disease and death.

 Since 2000, one billion bednets have been distributed (costing around 5 dollars each), and have averted 450 million cases of malaria — this suggests that, on average, one episode of clinical malaria can be prevented for about $11 (malarial fevers can be very painful. One recent study suggests that in Kenya, bednet distributions between 2003 and 2008 have prevented a death of a child for about $1,011 on average

The charity evaluator Givewell estimates that the cost per child death averted through bed net distributions funded by the 

 (even though these estimates are uncertain, they're roughly comparable to the new malaria vaccine, which is not 100% effective and experts say should be used in combination with bednets

, and we at Giving What We Can, rank the Against Malaria Foundation as 

. This is not only because we think it is the most cost-effective charity one can donate to, but also because of Against Malaria Foundation’s outstanding transparency and accountability.

 you can see video footage from distributions, as well as detailed financial statements. They also check if the nets they distributed are still hung every 6 months in a random sample of 5% the households (two years after distribution, 81% of nets distributed were still being hung up and the most comprehensive study suggests that bednets are almost never used for things like fishing

preventing deaths will not lead to overpopulation

We can all help to make the maps above more blue and green. The Against Malaria Foundation needs a minimum of $13.4 million to fill their funding gap next year 

. And if you want to keep up the fight long-term, why not join us, and more than 1400 people — among them 

development economists, moral philosophers, students, nurses, entrepreneurs, scientists and teachers

 to give 10% of your income to the charities that you think are most effective (or just 1% for those who don’t work full time).

We’re winning some impressive battles against one of history’s biggest killers. As more people start donating to a cause that is rigorously evidence-based and extremely cost-effective, we can start to win the war.

Bednets Have Prevented 450 Million Cases of Malaria

With the 2015 Giving Season upon us, we’ve reviewed our top charity recommendations so that you can make an informed decision about where to give.

This year we have extensively reviewed our 

We continue to believe that both the Against Malaria Foundation and the Schistosomiasis Control Initiative are some of the most effective giving opportunities and continue to recommend giving to them this season.

, which are charities we are not as certain about as our top charities, but that might have an even higher impact. 

The Against Malaria Foundation, which funds and provides technical assistance with distributions of long-lasting insecticide treated bednets, remains a top charity.We have written an 

 on the effectiveness of AMF’s bednet distributions

The charity evaluator Givewell has also updated their 

 and ranks AMF as their #1 charity. In brief, AMF has funded 

, which have and will avert much suffering and death due to malaria.

. However, there is still a major funding gap 

 for insecticide treated nets - which means that in the long-term there is a funding gap for AMF.

In the the short term, there is also a funding gap for AMF. Givewell estimates that even after taking into account the Good Ventures grant of $22.5 Million and what Givewell donors will give until February 2015 (~$15 million), and what other donors (which includes Giving What We Can donors) are expected to give until February 2015 ($1.6 million), AMF still needs about $13.4 million dollars in order for there to be at least a 50% chance for AMF to not to be funding constrained in the next year

In sum, because there is a big funding gap, and AMF has a good track record of distributing bednets as well as being accountable and transparent, we highly recommend donating to AMF this winter.

The Schistosomiasis Control Initiative provides technical assistance to governments with deworming programmes. We have written an 

 on SCI this year and Givewell has also recently updated their 

SCI has helped implement large deworming programmes in 2015 and plans to scale up and assist with even bigger operations in 2016

. For instance, SCI reports that up to the end March 2015, SCI contributed to delivering about 47 million deworming treatments overall, and from 1st April 2015 to 31st March 2016 alone it plans to help deliver 36 million treatments

unmet need for deworming treatment globally

 and thus a long-term funding gap. In the short-term, Givewell estimates that SCI needs about $4.9 million dollars in order for there to be at least a 50% chance for SCI to not to be funding constrained in the next year.

In sum, SCI remains a top charity. We believe it is one of the most effective charities one can donate to.
