Explanation
The comic is a single large panel showing a person contentedly reading a book. The text on the book's page reads: "All of your biases have at some point been confirmed by anecdote." Below the panel, a caption states: "There. Now you never have to read anything written by a pundit."
The joke targets the world of political punditry and opinion writing. Weinersmith is pointing out that pundits essentially make their careers by cherry-picking anecdotes that confirm their (and their audience's) pre-existing biases. Rather than presenting rigorous analysis or data-driven arguments, pundits tend to find individual stories that support whatever point they already wanted to make. By distilling all of punditry down to this one sentence, the comic suggests you can save yourself the trouble of reading any of it.
The votey panel adds another layer, stating: "More good news! Your pet theories about society can be confirmed by info from a survey course in psychology." This extends the satire to people who use a shallow understanding of psychology (perhaps from a single introductory class) to justify their existing beliefs about how society works, further mocking the tendency to seek out superficial confirmation rather than genuine understanding.
