The psychology of decision-making examines how individuals choose between options, influenced by cognitive, emotional, and social factors. **Cognitive biases**, like the **confirmation bias** or **availability heuristic**, can distort judgment by focusing on pre-existing beliefs or recent information. **Emotions** play a significant role, often leading to impulsive or irrational choices, while logical reasoning typically leads to more deliberate decisions. **Social influences** and peer pressure also affect decision-making, as people may conform to group norms. Models like **rational choice theory** emphasize logical, benefit-maximizing decisions, while newer theories highlight the importance of unconscious processes and **bounded rationality** in shaping how we make choices.
