Effective altruists are most commonly donating to specific relatively high-evidence causes in low-income countries or much more speculative existential risk causes. Donations such as his donations to Carneggie Mellon University are an example of donations that is not common among effective altruists.

They're kind of missing the most important point of altruism being "effective". It's not that the recipient is effective with the money, it's that the net value of one's altruism is higher if you work and make alot of money and give it to donors rather than if you just did the work that the donors are doing. This is only applicable for those earning more than the people doing the work within the recipient organization of course.
