Brain Bugs: The Causes and Consequence of the Brain's Flaws

(upcoming book,  Norton)

 

   The entangled web of neurons within our skulls is not only responsible for our ability to recognize a companion by his or her voice, face, handwriting or gait, but much more mysteriously, to feel and express love for that person. The concept of zero, the discovery of biological evolution, the theory of special relativity, and the fact that there are humans strolling around with hearts that once belonged to someone else, all attest to the brain's astonishing ability to understand, invent, and create.

   The human brain is the most complex device in the known universe, yet, it is also a highly imperfect one. In addition to the impressive array of features embedded in the 1.3 kg conglomerate of cells that we carry around in our skulls, there is also an abundance of flaws and limitations – brain bugs. We are subject to, we are bad at numerical manipulations, our decisions are often anything but rational as a result of cognitive biases, our memory can be unreliable, we are easily manipulated by advertising, we have a propensity to engage in supernatural beliefs, what we fear is only tenuously related to what we should fear, and we are gifted practitioners of self-deception. Simply put, our brain is inherently well-suited for some tasks, but ill-suited for others; one of the latter is distinguishing which are which.

    Ultimately there are two main causes of our brain bugs. First the brain is running what amounts to a 100,000 year old operating systems. Second, the architecture of the brain contributes to a large number of brain bugs, including why it is harder to remember the name Baker then the profession baker, why we are so easily manipulated by advertising and why our supposedly rational decisions are often influenced by arbitrary and irrelevant factors.

    Brain bugs will explore to what extent the neural hardware and ‘operating system’ established by evolution remain well-suited for the digital, predator-free, sugar-abundant, special-effects filled, antibiotic laden, media saturated, high population density, intercontinental travel age we have managed to build for ourselves? Brain Bugs will explore and explain the neuroscience behind the brain’s bugs, and will reveal how its flaws shape our lives as individuals and as a society.
