"Dissonance is most powerful when it is about our self-image. Feelings of foolishness, immorality and so on (including internal projections during decision-making) are dissonance in action.
If an action has been completed and cannot be undone, then the after-the-fact dissonance compels us to change our beliefs. If beliefs are moved, then the dissonance appears during decision-making, forcing us to take actions we would not have taken before."
5. Lying to Ourselves: Cognitive Dissonance
One might begin to suspect that people must be pretty good at either ignoring their own feelings, beliefs and desires, or flat out lying to themselves (and getting away with it). In a classic 1959 experiment psychologists designed an experiment with level upon level of deceit to see just how much a person will ignore their own experience, even to the point of helping to convince someone else of something they know is not true.
The human capacity for sustaining cognitive dissonance has since been confirmed in many other well-designed experiments. This capacity is linked closely with our desire to join and fit in with a group, adjusting our own values and beliefs about things to align with those of others. Perhaps, knowing about these propensities, we can learn to avoid believing our own lies too much
The Western developed word is amidst a health crisis, brought on by diseases and conditions we have chosen to inflict upon ourselves because of our excessive consumption of hedonistic pleasures such as un-suitable foods, cigarettes, alcohols and illicit drugs, all of which are resources that have become all too readily available to our child-like; - what we want, how we want it, when we want it - consumer attitudes. In the UK we are burdening the NHS with more and more cases of self inflicted diseases and debilitating conditions which we can consciously prevent. The health risks associated with the indulgence in these resources isn't something that is infectious or contagious, something we have no control over, we human beings are making bad choices and giving ourselves these problems that need never exist... So why are we doing it? And how far will we have to go to change our infantile attitudes?
Resources we regularly over indulge in:
Unsuitable food
"Obesity can cause a number of health problems, such as type 2 diabetes (a condition caused by too much glucose in the blood), and heart disease (when the heart’s blood supply is blocked).
Being overweight or obese can also shorten life expectancy (how long a person should live). In obese adults over 40 years of age, obesity can shorten life expectancy by 6-7 years."
Illicit Drugs
"The 2009/10 British Crime Survey estimates that 8.6% of 16 to 59 year olds living in England and Wales have tried illegal drugs in the last year.
Among young people, this figure is more than twice as high, with an estimated 20% of 16 to 24 year olds having used illegal drugs in the last year.
"The cumulative effects of excessive alcohol consumption, especially when associated with a poor diet, affect every part of the body. The two main sites of damage are the liver and the nervous system."
"Alcoholism is also implicated in diabetes, inflammation of the pancreas, internal bleeding, weakening of the heart, high blood pressure and stroke. Alcohol intake during pregnancy is harmful to an unborn baby."
Smoking
"Smoking is a greater cause of death and disability than any single disease, says the World Health Organization. According to their figures, it is responsible for approximately five million deaths worldwide every year. Tobacco smoking is a known or probable cause of approximately 25 diseases, and even the WHO says that its impact on world health is not fully assessed."
