Friendly Duality of the Human Brain


  1. Human brains are 100% lateralized. The dynamic inter-generation optimization offered by the evolutionary process has resulted into the brain being so highly optimized; it is not possible to have such elaborate design without any purpose. Any information being processed in left or right hemisphere has a reason not only to be processed in that particular hemisphere, but also in the location where it is being processed
  2. In a normal intact brain, hemispheres compliment each other, much like best friends, in optimizing interactions and do not compete or dominate each other, nor do they play inhibitory roles or tug-of-war against each other, the way it is often suggested in current brain studies
  3. Disregarding causation makes the complexity of brain activity appear to be proportionate to billions of neurons and trillions of synapses it possesses, as evident in brain studies today
EXTRA: Neuroscience + DOS Model = Neuroscience 2.0

Neuroscience + DOS Model = Neuroscience 2.0

  • Using the common ground of causation, the DOS model connects psychology to neuroscience, thereby multiplying the overall knowledge of workings of the brain, akin to the Gestalt view "the whole is greater than the sum of its parts"
  • When integrated with neuroscience, the model can drastically save time, effort and energy by offering mature and conclusive outcomes compared to the current ones
  • The causal structure of the model enables solutions to be extrapolated from its mechanisms for phenomena not otherwise considered, offering new avenues in research
  • The causal structure of the model also makes it falsifiable, and thus more reliable than current brain sciences, which mainly rely on observations and opinions that can be distorted by false perceptions, chiefly due to the complexity of brain processing ...less


  • Being a functional model, the DOS model does not identify brain areas underlying its functional mechanisms, other than the incidental explanation of the overall brain structure
  • Many dual process theories and models have been proposed earlier, but none of them are fully causal and rely on observations and opinions, besides not being as comprehensive as the DOS model
