Is logical reasoning rational choice?

The art of logic seems to go hand in hand with the Rational Choice Theory. With the similar ideological premise being the process by which individuals make decisions can come to conclusions. With both processes there is a high regard for the notion of an individual.
With the Rational Choice Theory, which seems similar to the art of logic, an individual comes to a conclusion by assessing a particular situation, and with help from past experiences, point of view, and general needs or goals, the individual is able to make a rational choice, or a logical one. So with such reliance on experience and personal goals or objectives, does a person’s logical reasoning’s and decisions base solely on the individual? Does common logic, like common sense, depend solely on the individual?
In the court of law, the role of the judge is to deliberate and formulate reasonable decisions based on fact. They can use the deliberation of related cases in terms of a guideline if need be. So generally, do judges follow their own form of logical reasoning to make decisions? Like emotions, in the court of law, nothing can be taken at face value, and what might seem like the obvious logical decision in deciding a case, may take time and critical thinking outside the box to determine the right choice.
