Do you donate? If so, what is your criteria to donate? Do you think about the effectiveness of the organizations you donate or do you just get moved but smart campaigns? In my case, I just used to give money randomly on some homeless or begging people in the street and I used to volunteer in different activities because I didn't believe in donations effectivenes. But this summer I came across the book The most good you can do written by the Australian Philosopher and Professor Peter Singer and it completely changed my vision about donating and confirmed some ideas I have been thinking about lately.The book talks about the trend and movement named effective altruism. It includes people who choose careers and lifestyles to maximize the money they can generate or safe in order to donate the maximum possible money to proven effective organizations such as the NGOs rated in the platform GiveWell which fosters an analytical approach to NGOs. It is important to be able to measure the effectiveness and impact of the actions and donations so we can have smarter decisions on where and how to donate. And it is also important that we choose the best way to help. We have approximately 80000 hours in each of our careers as the 80000.org organization states. You can take a quiz and find some career guidance in order to find the path that will help you have a greater social impact with your career. Another idea related to the movement are the fact that is always better to donate to developing countries than to donate to already developed countries since the impact and return on donation is always going to be higher. In developing countries people easily find the social help necessary to have food and a roof and the country costs of, for example, The States, are much higher than a country like Uganda. This also includes the idea of valuing lives equally independently of where you are located or where you are from. Is it rational? Is it human? Is it real? Effective altruism proves it to be rational, human and real. The book also mentions some platforms where you can pledge to donate a certain amount of money per year depending on your location and income such as The Life You Can Save. I took the pledge and I am going to use some of the thoughts and one of the platforms mentioned in the book in order to choose effectively where to donate :)One of the facts from this movement which shocked me the most was the fact that some people has donated one of their kidneys since the probability of dying because of donating a kidney is one out of 3000. This reinforces the idea that people (at least some) value all the lifes the same and since numbers talk (statistically it is better to donate a kidney since saves a life against the 1/3000 possibility of dying) they choose to donate their kidney. Awesome right? Altruism does exist. The book is a real inspiration and these were some of my key learnings reading the book. It really confirmed me the idea I have been obsessed about lately. Our time is our measurement of life and the most valuable resource we have: we definitely need to think and choose well how do we want to invest our time! Sometimes some careers such as consultancy may seem boring or just a way to keep the status quo, but they can be a real tool for a greater and better social impact :)
