Logical fallacies, despite their deceptive appearance of correctness, often mislead analysts during technical problem analysis, leading to erroneous conclusions and prolonged issue resolution times. This presentation elucidates the common logical fallacies that frequently arise in technical problem analysis and how they can obscure the root cause of issues. By identifying these fallacies and employing strategies to mitigate their influence, those analyzing technical issues can improve product reliability, adherence to schedules, cost efficiency, and maintain the reputation of their organizations. Key fallacies discussed include False Cause/Correlation, Fallacy Fallacy, Ad Hominem, Personal Incredulity, Red Herring, Burden of Proof, Gambler’s Fallacy, Bandwagon or Appeal to Popular Belief, Appeal to Authority, Genetic, Black or White (False Dilemma), Appeal to Tradition, and Appeal to Ignorance (ad ignorantiam). Through real-world scenarios and practical tips, the presentation emphasizes the importance of grounding technical problem analysis in sound logic and evidence to avoid common pitfalls and achieve effective solutions.
