Selective Information Processing: How Our Minds Protect Beliefs

We have a lot going on in our minds. Information constantly flows from the environment to our brains. We pick up cues of danger and opportunity through multiple senses. However, not every threat or opportunity is obvious. We must sort through the millions of fragments of information, sew them together to create an identifiable meaning. Our minds act as meaning making machines sorting, organizing, and creating. In the process of deciphering meaning, we discard majority of the data, labeling it irrelevant, and move forward. In psychology, we refer to this as selective information processing.

Selective information processing is an adaptive response to our brains limited capacity to process large chunks of data in the environment. Largely, we manage just fine with our unconscious picking and choosing which data is relevant and which data is not. The stranger hiding in the shadows is relevant, the type of tree casting the shadow is not.

Scientists theorize we maximize our brain’s capacity by weeding out unnecessary information. Once we arrive at the most salient theme, we absorb only the most relevant information and discard the rest. However, weeding out information is subject to bias, and trimming of information will likely verify pre-existing narratives and mindsets.

Narratives

We organize the perceived data into a handy narrative for storage. Rosamund and Benjamin Zander explain: “All of life comes to us in narrative form; it’s a story we tell.”

They then go into detail on the process of creating a narrative:

“First, our sense brings us selective information about what is out there; second, the brain constructs its own simulation of the sensations; and only then, third, do we have our first conscious experience of our milieu. The world comes into our consciousness in the form of a map already drawn, a story already told, a hypothesis, a construction of our own making” (Zander & Zander, 2002).

The Zanders aptly conclude that we perceive “only the sensations we are programmed to receive, and our awareness is further restricted by the fact that we recognize only those for which we have mental maps or categories” (Zander & Zander, 2002).

Our narratives, stuffed with selective information, have some notable flaws. Underlying functions eliminate relevant data, narrowing our mind, and biasing our views.

Cognitive Dissonance and Selective Information Processing

We strive to maintain a homeostatic balance. Preventing undue arousal is a common self-regulation strategy, keeping our system from undue discomforting arousal. One strategy for preventing arousal is eliminating conflicting information. Basically, once we create a narrative, information inconsistent with our narrative conflicts, violating our expectation, and demands attention to reconcile our narrative with new incoming information.

According to Leon Festinger’s cognitive dissonance theory (Festinger, 1957), we are predisposed to avoid conflicting information. We may accomplish this in several ways. We may selectively choose to avoid environments that will challenge our beliefs (narratives), or unconsciously we dispose of unwanted information (selective information processing).

Factors Motivating Selective Information Processing

Selective information processing isn’t our default mode. Mostly, we prefer to correctly receive and process incoming information. However, our limited abilities can’t always enjoy this luxury. For us to adequately respond to our dynamic environments, we must take cognitive shortcuts, employing heuristics by relying on structures that we already accept. Several conditions lead to a significant selective processing of new information.

High Information Load

The more complex the information, the greater the need to trim away the fat. Processing vast amounts of information is time confusing, draining energy, and depleting available resources for other tasks. Researchers found that, “When more than two pieces of information were available, the complexity of decision making was higher, motivating individuals to reduce the complexity of decision making by searching for decision consistent information” (Yoon et al., 2012).

These findings match with the basic premise of cognitive load theory. When cognitive load is high, learning is inhibited.

Strong Commitment to a Position

When we are highly invested (ego investment), information that challenges our belief threatens our livelihood or sense of importance. We are unconsciously motivated to disregard such information as important, while highly attentive to information that supports our invested position.

Alfred Adler wrote: “We all ignore the whole and value only that which is appropriate to our goal.” He explains this begins early in development. “Children,” he wrote, “perceive only those elements in their environment that fit into a behavior pattern previously determined by a variety of cause” (Adler, 2009).

Irreversible Decisions

We make wrong decisions. Repeatedly. Error is par for the course while living in a dynamic and complex world. Many choices can be undone. We can go back, make changes, and move forward in confidence. However, some decisions are irreversible. Our decision causes irreparable damage or drains irreplaceable resources. In these events, we are more likely to selectively process information to mitigate the shame of our costly error.

Negative Affective States

Our moods influence decisions, modify receptivity to information, and protectively avoids additional stress. During negative affective states our mood already is draining valuable resources. In our limited capacity, our minds and bodies go into protection overdrive, selectively processing only necessary information.

Associated Concepts

• Information Processing Theory: This cognitive psychology theory studies how people acquire, store, and use knowledge. It suggests that the human mind processes information in stages, such as encoding, storage, and retrieval, similar to a computer.
• Selective Attention: This concept refers to the process of focusing on a particular object or task for a certain period while ignoring irrelevant information. It’s a crucial mechanism because our cognitive system can handle only a limited amount of information at a time.
• Filter Theories of Attention: These theories propose that attention operates as a filter between sensory stimuli and processing systems. For example, Broadbent’s Filter Model suggests that stimuli are filtered at an early stage before they are processed for meaning.
• Bottleneck Theories: These theories suggest that there is a ‘bottleneck’ or a narrow passageway through which information must pass, and only a small amount of information can pass through at a time. This limits the amount of information that can be processed simultaneously.
• Feature Integration Theory: Proposed by Anne Treisman, this theory explains how an individual combines different attributes of a stimulus, such as color and shape, into a coherent perception, with selective attention playing a crucial role in this process.
• Cognitive Load Theory: This theory deals with the amount of information that working memory can hold at one time. It suggests that selective information processing is necessary to manage cognitive load and prevent overload.
• Schema Theory: Schemas are cognitive structures that help us organize and interpret information. According to schema theory, we selectively process information based on our existing schemas, which can influence what we pay attention to and remember.

A Few Words by Psychology Fanatic

As we navigate the complexities of our daily lives, it’s crucial to remember that our minds are wired for selective information processing. This inherent ability serves as a mental shield against overwhelming data, yet it can also blind us to critical insights and alternative perspectives. By unconsciously filtering out what doesn’t align with our preexisting beliefs or narratives, we risk missing valuable information that could challenge our assumptions and broaden our understanding. Therefore, it’s essential to approach new ideas and experiences with a sense of curiosity rather than complacency.

To foster personal growth and informed decision-making, make it a habit to routinely check for information you may have overlooked. Engage in discussions with diverse individuals who hold different viewpoints; read widely across various sources; and reflect on your own cognitive biases. Regularly stepping outside of your comfort zone can help unearth hidden truths and reveal patterns you might otherwise miss. Remember, embracing discomforting new information is not just an intellectual exercise—it’s a vital practice for cultivating open-mindedness and resilience in an ever-evolving world.
