Another study conducted in the US revealed that white patients were more likely to receive heavier painkillers from their doctors than were African-Americans or Latinos.

Even though those decisions may occasionally be strengthened by conscious thought, the unconscious half of the brain is wholly responsible for generating them. This process, which begins relatively early in childhood, has even been identified by scientists as to which areas of the brain are involved.
