Dug around and found my list but will likely re-evaluate now (since it's been 5 months or so) against the original 50:
4. Underestimating coping ability. Underestimating your ability cope with negative events.
6. Biased attention toward signs of social rejection, and lack of attention to signs of social acceptance. For example, during social interactions, paying attention to someone yawning but not paying the same degree of attention to other cues that suggest they are interested in what you’re saying (such as them leaning in).
7. Negatively biased recall of social encounters. Remembering negatives from a social situation and not remembering positives. For example, remembering losing your place for a few seconds while giving a talk but not remembering the huge clap you got at the end.
15. Recognizing feelings as causes of behavior, but not equally attending to how behavior influences thoughts and feelings. For example, you think “When I have more energy, I’ll exercise” but not “Exercising will give me more energy.”
24. Minimizing. e.g., “Yes I won an important award but that still doesn’t really mean I’m accomplished in my field.”
25. Magnifying (Cognitively Exaggerating). For example, blowing your own mistakes and flaws out of proportion and perceiving them as more significant than they are. Making a mountain out of a molehill, but not quite to the same extent as catastrophizing.
29. Falling victim to the “Foot in the Door” technique. When someone makes a small request to get a “Yes” answer, then follows up with a bigger request, people are more likely to agree to the big request than if only that request had been made.
38. In-group bias. The tendency to trust and value people who are like you, or who are in your circle, more than people from different backgrounds.
39. "You don't know what you don't know." Getting external feedback can help you become aware of things you didn't even know that you didn't know!
42. Biased implicit attitudes. Psychologists use a test called the implicit association test(link is external) to measure attitudes that people subconsciously hold. Results show people subconsciously associate fat with lazy etc. It's useful to be mindful that you may subconsciously hold biased attitudes, then you can consciously correct for them.
43. The Peak-End Rule. The tendency to most strongly remember (1) how you felt at the end of an experience, and (2) how you felt at the moment of peak emotional intensity during the experience. Biased memories can lead to biased future decision making.
