Today's episode of Rationally Speaking is sponsored by Givewell.

Givewell takes a data-driven approach to identifying charities where your donation can make a big impact.

Givewell spends thousands of hours every year vetting and analyzing nonprofits so that it can produce a list of charity recommendations that are backed by rigorous evidence.

The list is free and available to everyone online.

for donors who are interested in having a high altruistic return on investment in their giving.

Its current recommended charities fight malaria, treat intestinal parasites, provide vitamin A supplements,

and give cash to very poor people. Check them out at givewell.org.

You've published philosophy papers. What was your actual degree in?

I have an engineering degree.

It confuses people a little bit because I did write one work in philosophy,

but it's not published in any journal or anything like that.

I don't know if maybe you don't have the equivalent in the United States,
