Explained: Cognitive Bias Theory And Its Relevance In Today¡¯s Time

Cognitive Bias theory refers to the tendency of the human brain to streamline complex information in simple ways, processing it through the filter of personal experiences, prejudices and preferences. This process of filtration of information helps brain to simplify large chunks of information and process it more swiftly.

Where did it started from?

The emergence of this theory can be traced back to early 1970s when Amos Tversky and Daniel Kahneman introduced the term cognitive bias to describe people¡¯s systematic yet flawed patterns of responses in relation to human judgement and decision-making. They proposed various cognitive biases, including the framing effect, availability heuristic, and representativeness heuristic. Their work challenged traditional assumptions about human rationality and highlighted the systematic errors and biases that influence our thinking.

Since then, numerous researchers from various disciplines, including psychology, behavioral economics, and neuroscience, have contributed to the understanding of cognitive biases. This ongoing research has expanded our knowledge of the different biases, their underlying mechanisms, and their implications in different contexts.

Various kinds of Cognitive Bias

There are numerous types of cognitive biases that have been identified and studied by researchers. Here are some common types of cognitive biases:

1. Confirmation Bias: The tendency to seek, interpret, or remember information in a way that confirms preexisting beliefs or hypotheses, while ignoring or dismissing contradictory evidence.

2. Availability Heuristic: Relying on immediate examples or information that comes to mind easily when making judgments or decisions, without considering the overall probability or statistical data.

3. Anchoring Bias: The tendency to rely too heavily on the initial piece of information encountered (the "anchor") when making subsequent judgments or estimations.

4. Hindsight Bias: The inclination to perceive past events as more predictable or obvious than they actually were, after learning about their outcomes.

5. Overconfidence Bias: The tendency to have excessive confidence in one's own judgments, abilities, or beliefs, often overestimating performance or underestimating risks.

6. Framing Effect: The way in which information is presented or "framed" can influence judgments or decisions, even when the content remains the same.

7. Confirmation Bias: The inclination to interpret or seek out information that supports one's existing beliefs or hypotheses while disregarding conflicting evidence.

8. Gambler's Fallacy: The mistaken belief that previous events in random sequences will influence future outcomes, particularly in games of chance.

9. Bandwagon Effect: The tendency to adopt or believe something simply because many others do, without critical evaluation or independent thinking.

10. Sunk Cost Fallacy: The tendency to continue investing in a course of action or decision, even if it is no longer rational, because of the resources (time, money, effort) already invested.

Relevance of Cognitive Bias in today¡¯s time

In today's era of information overload and digital media, cognitive biases have a significant impact on how we process and interpret the vast amount of information available to us. Two specific biases that play a crucial role in this context are confirmation bias and availability heuristic.

When confronted with new information, we often subconsciously filter it through the lens of our existing beliefs, paying attention to information that supports our viewpoints and dismissing contradictory viewpoints. In this Bias, individuals surround themselves with like-minded people and sources of information that reinforce their existing beliefs.

On the other hand, Availability heuristic is a mental shortcut we use to make judgments based on how easily relevant examples or information come to mind. In the digital age, information is readily accessible, and our brains tend to rely on easily available information when making decisions or forming opinions. This can lead to biases in information processing, as information that is more accessible or frequently encountered is given more weight and perceived as more accurate or representative, even if it may not reflect the overall reality. This bias can contribute to the spread of misinformation, as easily accessible but potentially inaccurate or biased information is shared and consumed more readily.
