Kind of surprised at your response. Nevertheless, a popular book that discusses this issue is" Start With Why" by Simon Sinek. An author/lecturer that created a following as a result of his famous TED talks presentations. In the aforementioned book in Chapter 4 titled "This Is Not Opinion, This is Biology" it discusses, among other things, the roles of left and right brain functionality/orientation re: decisions people make and how they're influenced.
My personal opinions are shaped by many other medical experts. This happens to be a more contemporary perspective that a casual student could absorb. If you are employed in the Real Life business world, this book would be recommended reading .Figured you, Hans or Lurker could do some forensic fact checking to validate.
Don't want to derail OP. Enough said.
