But only to smart causes. The power couple is interested exclusively in “impact giving.”

They, for example, plan to fund a comprehensive experiment on what causes obesity. There is much more to know about how the body processes food. A study like this could lead to effective advice not just on obesity but also on other dietary issues; it could improve well-being for virtually everybody.

Along with obesity, they also want to dig into criminal justice and pension reform.

The Arnolds want to give their money to projects that will contribute to the wider depository of human knowledge. Causes have to show a scientific approach to prove that the projects have a high probability of working.

The Arnolds have been criticized for not giving to more immediate (non-experimental) causes. Their public donations focus on public policy problems that create “moral inefficiencies”. They want to help society by making it smarter.

According to The Chronicle of Philanthropy, last year, at $423 million give this far, they are the third-highest givers in the country.

Some philanthropers give money to maintain an image. Some give money to help organizations that helped them. And some, like the Arnolds, give money to actually improve society. The fact that the Arnolds think about the causes they’re supporting in terms of scientific inquiry, implementation, and impact rather than just randomly writing checks indicates that they care both deeply and smartly.

South Korea’s education system is considered superior in comparison to the United States. One reason for this is the amount of time and money South Korea puts into tutoring their kids and the way in which they are raised. The rate at which South Korean kids graduate is 93% compared to 77% in the United States. Although after school tutoring is becoming more common in other parts of the world, none have come close to the success of South Korea’s. Currently the countries private tutors outnumber school teachers.

It seems that the country of South Korea and the private education sector have instilled a new sense of the word education. The amount of school a kid receives with regular day school and then tutoring on top of that is quite a grind for a young child. Looking at the graduation rate in South Korea, it is highly apparent their efforts are working and will only continue to improve moving forward, while creating more opportunities for teachers like Kim Ki-hoon.
