The old concept of the brain and decision-making divided the concept of thinking into very separate "rational" and "emotional" components, while the current view is these components are integrated and overlapping. When decisions are personal, even if they are not emotional, the emotional part of the brain (the ventromedial frontal lobe) is actively involved. Even everyday decisions, such as whether to take a hot bath or use a seat belt, have an emotional component. This is one reason that it is difficult for people with certain types of brain injury to make so-called rational personal decisions.
