  • A mental framework used to understand the world. We formulate schemata for every new situation we encounter, and store them away in our minds for recall when similar situations occur in the future. A person's collection of schemata is usually congruous with itself, resulting in a gestalt perception of the world that is logical and harmonious.

    Occasionally a person will encounter a crisis, or circumstance that markedly contradicts his or her existing framework, leading to a difficult period of schemata reevaluation/redefinition. This process, known as cognitive dissonance, can be painful to go through. It usually involves intense questioning of one's faith or values, lingering self-doubt, and a disconcerting sense of fear (as if the world known to that person has suddenly ended). In some cases, the process may never be fully resolved, often resulting in social withdrawal, depression, or bitterness. In other cases, it serves as an impetus for positive change.

    Because of the difficulty of the process, our natural defense mechanism is to reject anything that might challenge our schemata. It is easier to remain "blissfully ignorant" than to tear down an existing worldview and build a new one from scratch. We do ourselves a great disservice by this, however, essentially refusing to grow! When we are presented with challenging ideas, we must take care to avoid logical fallacies as we evaluate them. Only with an open mind can we be honest to ourselves, and mature in our perception of the world.
