Effective Selfishism?

Most people are selfish in their want to give. If someone close to me suffers from a specific form of cancer, I would be really motivated to give to that cause, in hopes that further research would lead to improvements in that area, and keep other people from going through the same suffering.

Therefore I’d argue, it would be WELL WORTH IT to curate a list of the most effective way to give towards research /​ relief regarding specific diseases. This would also motivate funding beyond what a single could ever contribute.

Sadly I am unable to find such a form of curation, most of the “giving effectively” foundations focus around a few select, broad topics. Would this be worthy of a project to pick up?
