Two years ago I completed the popular P90X workout/diet program. The physical results were astounding. After 90 grueling days, I managed to transform a completely average body into a muscular, chiseled, flexible, and highly-efficient one. The before and after photos alone were enough to motivate friends, family, and coworkers to begin the program themselves. However, the program involves no groundbreaking exercises, no secret weight-loss pills, and no high-tech exercise equipment. The only secret of the program lies in consistency. You workout 7 days a week and the diet is followed every hour of the day. P90X simply leverages the human body's ability to change through consistency. Anything you practice for 1 hour a day for 90 days will produce results. That's the secret - and it's a powerful one.
What we have difficulty realizing however, is that our brain works in the same way as our body. The only significant difference between the processes of physical adaptation and psychological adaptation is that the results of one are largely visible while the results of the other are largely invisible. We can confidently state that in our society, greater value is placed on visible results.
Our environment literally rewires our brains
The weaving of new neural connections and unweaving of old connections is termed "neuroplasticity" and it defines our brain's ability to change. From the moment of conception until the moment of our last breath, the brain is physically molded by external stimuli (relationships, nutrition, career, advertising, etc.) as well as internal stimuli (thoughts and emotions). The longer we expose ourselves to the same stimuli (consistency), the stronger the consequential connection becomes. And since our brain "doesn't care" whether the stimuli is good or bad (i.e. smiling at a baby as opposed to committing murder), the neural connections are formed independent of your desire or moral judgment. In short, the more a certain stimuli pervades your life, the more your brain seeks it out. You don't even have to do anything for these connections to form - simply thinking or feeling is enough to lay building blocks in the mind.A brain that is constantly exposed to negative stimuli will become conditioned to it. Feeling guilty and pessimistic day in and day out will eventually become the "new" normal thanks to the adaptive nature of the brain. This is how most well-marked psychological traits - including optimism, trust, depression, anxiety, ADHD, bipolarity, and even cultural traits - develop. The typical Japanese, for example, tends to think of him/her self as part of a group while the typical American has been conditioned to individualism. The foundations for these states are mapped out in the brain through the physical restructuring of neural pathways. Once formed, they are very difficult to change and impossible to change quickly. This can be positive if the environment promotes positive attributes such as empathy, appreciation, and generosity... but what if the promoted attributes are negative? What if the environment lays the wiring for selfishness, inadequacy, materialism, superiority, and narcissism?
Is it then the individual's fault if they freefall into the bowels of depression even in affluence? Are they solely responsible for developing a disastrous self-image and a distorted perception of beauty? Are they to blame if they commit murder due to a suppressed sense of esteem and respect for others? Who's to blame? Their parents? And if the parents were subjected to the same neural conditioning? Hmmm.
