I’d say that consuming content that only confirms your biases is a form of failing media literacy as you’re failing to see the biases inherent to the content you’re consuming. There’s the flaw of “I think it’s this way” seeking out that content and not seeing that it’s poorly sourced (if at all) and eating it up.
Not to mention the role that content suggestion algorithms play in reinforcing that behavior and providing you with even more content along the lines of the biases you’re reinforcing.
It’s a complicated can of worms for sure.
One of the many reasons why when I play characters in D&D I play characters
“This character? They’re Milton the Barbarian. Him and his brother Bradley are trying to start a toy business but were struggling for funds to start. So while Bradley went with the safer route of getting money by becoming an apprentice toy maker Milton chose adventure for some quick cash.”
And so many others
It’s really fun to make new characters and see how they’d handle things. Putting them in new situations and fleshing them out.
