Don't scrape or bulk-download the site for republishing or resale, attempt to disrupt or gain unauthorized access to it, or use it to harass or mislead others. Links to external books, articles, courses, and podcasts on the Resources page are not endorsements of those sites.

## No warranty, liability, and governing law

The site is provided "as is" with no guarantee it is complete, error-free, or always available. These terms don't name a specific court; disputes start with emailing contact@criticalthinkingexercise.org. Terms may be updated from time to time.
