Believed Behavior is a curated, subscription-based website where independent, alternative cartoonists have the opportunity to post serialized work. This work is collected into seasonal newsprint anthologies that paid subscribers can choose to receive. The main focus is to showcase underground/alternative art comics by cartoonists interested in challenging the comics medium in print and web.

Believed Behavior was started in fall 2013 by Andy Rench, a Chicago-area web & graphic designer and a huge comics fan who also runs a blog about comics, posters and books called Printed-Matters.
