Our emotions affect our decisions every day (and our decisions end up affecting our emotions too). It is sometimes very hard for someone to disregard their emotional signals when making a decision than making the logical, best choice. It's behavioral learning. Our previous experiences made gave us either positive or negative reinforcement. We react to similar circumstances in the future based on how they make us feel or how we learned that circumstances in the past made us feel. It's how we develop biases instead of looking at each situation individually. It also protects us from making the same mistakes over and over again.
