I learned a long time ago already not to trust my memory. For example I'm trying to find a piece of text in a book, or a specific story in a newspaper my memory might give me a clue, which would be something like "it's on that page next to that "red thing" or "there's a story on the opposite page about xyz". I never trust this anymore it's a wild goose chase.

A good thing to think about how biased your brain is, is to think of that time when you were witnessing that wonderful sunset and you decided to take a photo. Later you look at the photo and it doesn't look at all like you remember. Why? Because it's your brain playing tricks on you. You have a built in image filter in your brain that adjusts the image and your memory of it whereas the camera sees it "objectively."

Once you become aware of all the cognitive biases you just get tired of listening to people talk (about anything really), when it's full of logical holes and anecdotes. In fact it becomes painful especially when listening to some electoral candidate / politician talk about stuff that might actually matter. sigh
