Decisions are driven by two opposing cognitive processes: logic and emotions. Although the two can sometimes be confused, determining whether your decisions are driven by logic or emotions is a key element of ensuring that you're making the greatest options for your long-term happiness. Most decisions are influenced by emotions, despite the fact that most people believe they approach decision-making through rationality. Emotions are really powerful. However, logic - the ability to make judgments based on solid and rational thought processes - may be lacking in your life.

Both Decision-Making Tools Have Flaws

Both of these decision-making techniques have advantages and disadvantages. Logic is, by definition, a method of decision-making that employs sound and rational reasoning to get the optimal result. Emotions, on the other hand, are genuine emotions. If logic is the brain, emotion is the heart, then happiness is found in the heart. But what about their shortcomings? Both decision-making tools have flaws. Some of these problems are discussed more below.

Logic: 

Requires Emotion - Logic cannot always be accomplished without emotion, especially when making life-changing decisions. After all, relationships, careers, and other key decisions are not typically made on paper. For example, a partner may appear attractive on paper, but they do not elicit sentiments of love and enthusiasm. If this is the case, they may not be the best partner for you.
Energy is required - Logic is not always an easy procedure. A rational conclusion may need more mental and physical energy than available time and attention. It can be difficult to reach a logical conclusion fast, for example.

Emotions: 

They Can Lie - What you are feeling may not be what is best for you or what your heart truly desires. Many former partners, for example, miss their connection after they break up. Some may even give in and reconcile. However, this is a mistake because missing someone (an emotion) is typical after any relationship simply because a part of your life has changed.
Could Be Irrational - Emotions are not regulated by reasoning by default. As a result, given the circumstances, you may have utterly unreasonable feelings. Anxiety and depression are extreme manifestations of this condition. In addition, emotions can change the way you think and control behavior, which may mean that your “logic” may be affected by emotions. This happens often to those struggling with mental health conditions, like depression and anxiety, where their emotions make them think in illogical ways.

Which is superior?

In many respects, rationality outperforms emotion. The more critically and objectively you can think about a decision before making it, the more likely it will be the right decision for you. The fewer impulsive or irrational decisions you should make, the less you should be influenced solely by emotion and instinct.

However, you should not be emotionless. Emotional factors continue to influence decision-making, including logical decision-making. Love and accept your feelings, but also have a strong sense of reasoning.
