Cognitive biases are systematic patterns of deviation from rational judgment. Understanding them helps us make better decisions and think more critically.

🧠 Decision-Making Biases

• Anchoring Bias – The first piece of information sets a reference point
• Choice-Supportive Bias – After choosing, we seek confirmation it was right
• Outcome Bias – Judging a decision by its result, not by its quality

🔍 Information Processing Biases

• Availability Heuristic – Judging likelihood by what is most vivid or recent data
• Confirmation Bias – Seeking and valuing information that confirms existing beliefs
• Selective Perception – Interpreting information through personal beliefs and experiences
• Survivorship Bias – Focusing only on successes and ignoring failures

👥 Social Biases

• Bandwagon Effect – Adopting beliefs or behaviors because many others do

🙈 Avoidance Biases

• Ostrich Bias – Avoiding unpleasant or threatening information

💭 Self-Perception Biases

• Overconfidence – Overestimating one's knowledge or abilities
• Placebo Bias – Improvement due to belief, not real effect
