This work examines the relationship between education and excessive confidence in situations of uncertainty. For this purpose, a questionnaire with 10 pseudo general knowledge questions was designed, whereby their degree of difficulty exceeds the knowledge of an average student by far. It was investigated whether subjects (N = 535) would acknowledge this condition and its associated nescience. If that is the case, they will answer the 10 questions within an extremely wide confidence interval in order to meet the predefined 90% accuracy requirement. The focus of investigation was in Southern Germany, as the school system regularly receives top marks in national educational rankings. The data analysis resulted in the stochastic proof that there are significant differences between the various educational institutions in accuracy and overconfidence.
In addition to the empirical study the paper defines the distortion of judgment and identifies its relevant factors. It gives a detailed explanation of the German education system and states the criticism of the concept of overconfidence. The paper concludes with a recommendation for action and ventures a look ahead.

Diese Arbeit untersucht den Zusammenhang zwischen Bildung und übermäßigem Selbstvertrauen in Situationen von Ungewissheit. Dazu wurde ein Fragebogen mit 10 Quasi-Allgemeinwissensfragen entwickelt, wobei deren Schwierigkeitsgrad das Wissen eines durchschnittlichen Schülers bei Weitem übersteigt. Es wurde untersucht, ob die Probanden (N=535) diesen Zustand und ihre damit verbundene Unwissenheit anerkennen und zur Beantwortung der 10 Fragen, innerhalb eines vorgegebenen 90% Konfidenzintervalls, jenen Vertrauensbereich möglichst weit wählen, um die Anforderungen zu erfüllen. Der Fokus der Untersuchung lag in Süddeutschland, da das dortige Schulsystem regelmäßig Bestnoten im nationalen Bildungsvergleich erhält. Die Datenauswertung resultiert in der Erbringung des stochastischen Beweises, dass es zwischen den Bildungseinrichtungen einen signifikanten Unterschied beim Schätzverhalten und der damit verbundenen Vertrauens-Hypertrophie gibt.
Neben der empirischen Untersuchung definiert die Arbeit den Begriff des übermäßigen Selbstvertrauens und benennt die relevanten Einflussfaktoren. Das deutsche Bildungssystem wird dabei ebenso beleuchtet, wie die Kritik am Konzept der Heuristik. Die Abhandlung endet mit einer Handlungsempfehlung und einem Ausblick in die Zukunft.

Research Objectives and Themes
This thesis examines the relationship between formal education and the cognitive phenomenon of overconfidence in uncertain environments. By utilizing a questionnaire featuring pseudo-general knowledge questions, the research evaluates whether individuals recognize their lack of knowledge and adjust their confidence intervals accordingly, or whether they exhibit irrational, overconfident behavior regardless of their educational background.
- The psychological definition and mechanisms of overconfidence.
- The influence of the German education system and the Bologna Process on student cohorts.
- Empirical testing of calibration and misjudgment among students from various educational tracks.
- Analysis of potential confounding factors such as gender, age, and mental health.
- Evaluation of whether higher levels of education correlate with better calibration and reduced overconfidence.
Excerpt from the Book
1. Overconfidence: The Harmful Optimism
The ability to expect a rosy future and solidly trust in our skills empower us to create monuments of human capability and push mankind toward unexpected technological findings. Marie Curie and her husband Pierre found the fission products radium and polonium and developed the first methods to isolate them in order to use both for further research (Nobel Lectures, 1967). The Chinese Ming Empire finished the Great Wall of China, the biggest man-made structure ever built, in 1620 (UNESCO World Heritage Centre, 2011). Every year millions of people start their own business all around the world; others get married and start a family. Every person who makes such a decision does it because of their faith in their own actions. It is, however, uncertain whether Marie Curie would have continued her intensive research with radium if she had known that radiation causes severe illnesses. It can be seen as certain that the Ming Emperors would not have reconstructed the Great Wall if they had been informed that it would not protect them from being replaced by the Manchurian Qing Dynasty.
This is not only true for historical events, but also for modern decision making. If US Americans decide to get married, most do not take into account that they could be the one out of three couples that divorce (U.S. Census Bureau, 2012). In 1993, when the U.S. divorce rate was close to 50%, a study tested whether people are aware of these numbers before they tied the knot. Although the subjects knew the facts, not one of them thought that this would happen to their relationship (Baker and Emery, 1993). This was unexplainably optimistic and on average not true for almost every second couple. Startup owners tend to share the same view of their business ideas. In a well-known survey, entrepreneurs rated their expected business success. 81% of the 2,994 participating founders thought that their chances of success were 70% or higher. Every third person stated that his chances were not less than 100% (Cooper et al., 1988).
Summary of Chapters
1. Overconfidence: The Harmful Optimism: Introduces the concept of overconfidence and its dual nature, showing how it can drive human achievement but also lead to disastrous misjudgments in critical decision-making scenarios.
2. Methodology: Outlines the design of the empirical study, explaining the use of a ten-question questionnaire to test student calibration and the selection of participants across various school types in Southern Germany.
3. The German Education System: Describes the conceptual framework of the German federalized school system and discusses how the Bologna Process has influenced student mobility and degree structures.
4. Review of Literature: Provides a theoretical overview of overconfidence, exploring key psychological biases and potential confounders like gender, age, and mental health, while also addressing academic criticism of the concept.
5. Empirical Research: Presents the findings from the student surveys, testing hypotheses regarding the link between education levels and confidence calibration through statistical analysis.
6. Conclusion: Summarizes the key insights, confirming that overconfidence is pervasive regardless of education, and suggests that awareness and specialized case studies are necessary to improve metaknowledge.

Frequently Asked Questions
What is the fundamental focus of this research?
The work investigates the link between educational background and the prevalence of overconfidence in individuals when making decisions under conditions of uncertainty.
Which central themes are explored?
Central themes include the cognitive mechanisms behind overconfidence (such as the Better-Than-Average Effect), the structure of the German school system, and the impact of information and education on the accuracy of human judgment.
What is the primary objective of this study?
The primary goal is to determine if statistically significant differences in overconfidence exist between students from different educational institutions using a calibrated questionnaire.
What scientific methodology is applied?
The author employed an empirical study involving 545 participants, who were asked to complete ten difficult general knowledge questions and provide a 90% confidence interval for their answers.
What does the main body of the work cover?
It covers theoretical definitions of overconfidence, detailed explanations of the German school system, a thorough literature review of psychological confounders, and the empirical analysis of survey data collected from school and university students.
Which keywords characterize this work?
The work is characterized by terms such as overconfidence, metaknowledge, behavioral economics, calibration, and educational influence.
Does a higher level of education significantly decrease overconfidence?
The study concludes that once a certain level of education is reached, further education does not significantly increase judgment accuracy or reduce overconfidence in the test scenario.
What were the findings regarding age and overconfidence?
The data revealed that age does not have a positive correlation with judgment accuracy; older participants in the sample did not demonstrate better calibration than younger students.
Was there a gender difference observed in the study?
Yes, the data indicated a statistically significant gender difference, with female students on average showing higher levels of overconfidence compared to their male classmates.
