Information Bias

Many of my posts have touched on the concept of perceiving Truth. It's an important topic to people - we rarely questions our own sense of truth and it scares a person when his sense of truth is rattled. The model that people have a set sense of Truth and all new information follows is not new to psychology. The idea of how prevalent and regular this occurs, however, has recently rattled the sense of the Psyche, however.

As psychologists developed the model of Cognitive Psychology, they regularly used the two terms Assimilation and Accommodation to describe the ways in which we retain knowledge and build our personal models of the world. Each day we're faced with a plethora of new facts, sensations, images. As we take in the information, we compare that info to our sense of the world. While our view and concept of the world may grow bigger, we are assimilating the new information into our picture of the world. If pieces of information don't seem to match our map, we find ways to adjust the picture. As one example, consider the different ways we draw flat maps of our spherical world.

 

Cartographers pinch maps one way or stretch it another in order to show a round world on a flat map -- they have to make different accommodations in their representation of the world. The more accurate a representation a person needs, however, it becomes more difficult to assimilate that info as the map is drawn. Ultimately, a person may need to accommodate their concept of the world by using a globe.

Similarly, we can take in information that matches our own perception of the world, or we can change our perception of the world. For adults, accommodating our perception is a more difficult task -- think of all the learned information we have to reevaluate! We become victims of our own preconceptions - it can be easier to accept the information that matches our perception of the world and omit/forget/ignore any information that may not match. We unconsciously choose to see, hear, feel, smell, and taste only what reasserts our image of the world. This information bias can be benign and help keep our lives efficient. The dangers, however, come in the potential to miss vital pieces of information or perpetuate troublesome patterns of suffering in our lives.
The specific information bias is called confirmation bias -- we are biased toward the facts, figures, and examples that confirm what we believe is true. Where psychologists once provided a model where people at worst ignored new information, confirmation bias, demonstrates that we're even more difficult to dissuade. We not only ignore information that might challenge our perceptions, but we assimilate information in a way that helps perpetuate any faulty beliefs and interpretations. It becomes more and more difficult to find evidence that proves us wrong because our brain often strengthens its ability to identify only what it believes to be true.
Consider this study by Victor and colleagues which demonstrates that people suffering with depression are more likely to identify sad faces even on an unconscious level. Research continues to demonstrate that the anxious brain and the depressed brain regularly practice information bias - easily identifying facts in our life that prove the rule and (often unconsciously) ignoring facts to prove the exceptions.
It takes active practice to question assumptions and identify exceptions to our preconceptions. I frequently give clients tools that help draw out the exceptions. By helping our mind find reasons for joy, hope, satisfaction and through training the brain to more readily see these examples in our life, it becomes harder to stay depressed or anxious.
