The term ‘cognitive bias’, also known as ‘psychological bias’, was first mentioned by Amos Tversky and Daniel Kahneman at the beginning of the 1970s. It describes a phenomenon which happens uncountable times a day within the human brain: making decisions and judging issues although facing various limitations, such as, information or time. By using a heuristic tool one reaches a satisfying conclusion (cf. Wilke and Mata, 2012)
The paper on hand focuses on the confirmation bias.

Objectives and Topics
This paper examines the phenomenon of cognitive bias, with a primary focus on confirmation bias—the tendency to favor information that confirms pre-existing beliefs while disregarding contradictory evidence. It explores how this bias affects human decision-making across various domains such as legal proceedings, business statistics, and everyday life, while providing practical strategies to mitigate its influence.

Excerpt from the Book
The Confirmation Bias
The above described phenomenon can be defined as follows: A usually strong hypothesis accompanied with a complexity of the focused matter and a certain ambiguity about the same, constitute the confirmation bias. It is also known as the ‘myside’ bias. First theories about this specific bias have been published by Peter Wason in the 1960s. (cf. Jones and Sugden 2001, pp. 59-61 and 73) Beneath laboratory, also numerous real-world situations certify the existence of confirmation bias (cf. Christandl and Fetchenhauer, 2010, p. 132) within humans’ minds. This cognitive distortion relates to the way humans seek, interpret and recall information. It is used numerous times a day without consciousness and can be equaled to an internally automatic force. (cf. Kassin et al. 2013, p. 44) The confirmation bias leads to overvaluing data approving an initial assumption or belief. Even if those information does not provide any added value, it will be used as a positive evidence to match the person’s inner idea about a certain matter. Consequently, information incongruent with inner beliefs is minimized or even neglected. However, people still assume their thinking patterns would be based on rationality and prior experiences rather than selective information reception and unconscious filtering. This all goes in-line with the humans’ inner desire to be correct in the way they evaluate the world (cf. McRaney 2012, p.9) Hence, the confirmation bias existence possesses a remarkable significance in the daily live. Even profound live stances can be explained by the confirmation bias. Examples are the rooted beliefs of people, e.g. in terms of politics, religion or gender roles (cf. Christandl and Fetchenhauer, 2010 p. 132).
Summary of Chapters
1. Definition of Cognitive Bias: This section introduces the historical roots of cognitive bias and explains the basic heuristic functions that lead to simplified decision-making under uncertainty.
2. Confirmation Bias in Daily Life and Law: This chapter illustrates the practical impact of confirmation bias through real-world scenarios, including consumer choices and high-stakes legal cases like the Madrid train bombing.
3. Theoretical Background and Mechanism: This section details the psychological theories behind the "myside bias" and explains how unconscious information filtering affects rational thought processes.
4. Strategies for Overcoming Bias: This chapter provides actionable advice for individuals to mitigate confirmation bias by actively seeking disconfirming evidence and fostering an open-minded approach.

Frequently Asked Questions
What is the core subject of this paper?
The paper explores the psychological phenomenon of confirmation bias, examining how it influences human perception and decision-making.
What are the primary thematic areas covered?
Key themes include the historical definition of cognitive bias, its application in legal and business environments, the underlying psychological mechanisms, and methods for bias reduction.
What is the main objective of this study?
The goal is to explain how confirmation bias leads to the filtering of information and to identify ways to foster more objective reasoning.
Which scientific methodology is employed?
The author uses a literature-based analytical approach, referencing established psychological theories and real-world case studies to demonstrate the prevalence of the bias.
What is the focus of the main content?
The main content bridges theoretical foundations—such as the work of Wason, Tversky, and Kahneman—with practical observations in law, statistics, and daily personal decisions.
Which keywords define this work?
The work is characterized by terms such as Cognitive Bias, Confirmation Bias, Information Filtering, and Rationality.
How does confirmation bias impact legal decisions, according to the text?
The text cites the Madrid bombing case as an example, where investigators focused on confirmation bias-driven assumptions rather than objective evidence, leading to wrongful accusations.
Why do humans naturally fall into confirmation bias?
According to the text, it serves as an automatic force to order vast amounts of information and fulfills the inner desire to be "correct" in how we view the world.
How can one actively reduce confirmation bias?
The author suggests becoming aware of one's own thinking patterns, seeking out contradictory viewpoints, and engaging in discussions with people who have differing opinions.
Is the confirmation bias always harmful?
The author notes that while it often leads to errors, it can also function as a temporary heuristic tool that helps individuals make quick decisions in complex, data-heavy situations.
