This is going to be the shortest disclaimer ever.
The FTC requires bloggers to disclose possible hidden interests or unspoken biases in their content. I do this in only one way–book recommendations. I recommend books that have inspired me or changed my life, and any purchase you make helps to keep the site running.
This covers less than 10% of costs. The rest of what it takes to run The Polymath Project is funded by readers on our Patreon page.
