Cognitive biases are systematic patterns of deviation from rationality or norm in judgment and decision-making. These biases occur as the human brain processes and interprets information, often relying on mental shortcuts known as heuristics. While these shortcuts help prioritize and simplify complex information quickly, they can lead to errors in perception, judgment, and reasoning 

The halo effect is a cognitive bias where our overall impression of a person, brand, or thing influences how we feel and think about their character or properties. Essentially, one positive trait leads us to assume other positive traits.

Be aware of your initial impressions and question whether they’re based on looks or a single trait.

Evaluate people or products based on specific criteria or objective data, not just gut feelings.

This bias occurs when people with low ability or knowledge in a domain overestimate their competence, while those with high ability may underestimate their competence. 

Seek feedback from more experienced individuals.

Keep learning and reflect on what you don’t know — the more you learn, the more you'll recognize the complexity of a topic.

The framing effect is when people react differently to the same information depending on how it's presented — positively or negatively. 

Rephrase the information in different ways to see if your decision still holds.

Focus on the actual data, not the way it’s presented. Look for absolute values or facts instead of emotionally loaded wording.
