# š Personal Notes
## Summary:
The video outlines a wide range of cognitive biases, which are systematic patterns of deviation from norm or rationality in judgment, leading individuals to perceive reality in a distorted way. These biases affect our decisions, beliefs, and behaviors in various contexts, from everyday life to more complex situations.
### Key Points:
- **Confirmation bias**: The tendency to search for, interpret, and remember information in a way that confirms one's preexisting beliefs or hypotheses.
- **Dunning-Kruger effect**: The phenomenon where individuals with lower ability at a task overestimate their ability, while experts underestimate theirs.
- **Availability heuristic**: The tendency to overestimate the likelihood of events based on their availability in memory, which can be influenced by how recent or emotionally charged the memories are.
