The tendency not to see or compensate for our biases.
"I'm objective, you're biased." We can often spot the brain biases of others, but when it comes to our own, we're in la-la-land. We think that we're objective, reasonable and tuned into reality.
BrainTip: For starters, familiarize yourself with the biases described on this site. Become bias savvy. Next, think of a few examples of how your behavior demonstrates each bias. Better yet, write out the biases and your behaviors on index cards and post them on a bulletin board.
