Gerd Gigerenzer - Decision Making
How to make decisions in an uncertain world
Title Description Interviewee Producer Duration
Bounded rationality Herbert Simon's concept of 'bounded rationality' has spawned a lot of research interests in psychology and economics. Dr. Gigerenzer identifies three different interpretations of bounded rationality - two of which deal with the... Gerd Gigerenzer goCognitive 00:06:17
Decision making in small and large worlds One of the main distinctions in research on decision making concerns the availability of information to a decision maker. In so-called ‘small worlds’, all alternatives, consequences, and probabilities are known. In so-called ‘large worlds’,... Gerd Gigerenzer goCognitive 00:02:42
Gerd Gigerenzer - Decision Making Dr. Gigerenzer is one of the leading researchers in the field of human decision making. His research tries to find the mechanisms by which humans make decisions in real-world situations. Unlike many other models, Dr. Gigerenzer's approach... Gerd Gigerenzer goCognitive
Heuristics Heuristics are simple strategies that allow a decision maker to reach a decision quickly and with little effort. While most people view heuristics as 'second class citizens' compared to optimized algorithmic solutions. In this... Gerd Gigerenzer goCognitive 00:05:26
How I got into decision making In this personal account of how he decided to become a cognitive psychologist and focus on human decision making, Dr. Gigerenzer reveals that he also had the opportunity to earn money as a professional musician. Gerd Gigerenzer goCognitive 00:02:49
Medical decision making How are heuristics helpful in real-word situations? Dr. Gigerenzer describes how simple heuristics can improve medical decision making over much more complex solutions. By ignoring much of the available information, simple heuristics often are... Gerd Gigerenzer goCognitive 00:07:37
Selection of heuristics Sometimes, more than one heuristic could be applied in a given situation. In these cases a decision has to be made which heuristic to go with. Dr. GIgerenzer explains how these conflicts are resolved. Gerd Gigerenzer goCognitive 00:04:16
Take the best heuristic As part of their research on human decision making, Dr. Gigerenzer and his group try to find simple heuristics that can be shown to work well under realistic assumptions. The 'take-the-best' heuristic is an important example of how a... Gerd Gigerenzer goCognitive 00:05:21
The role of intuitions Intuitions play an important role in many real-world decision making situations, yet they are often discarded as flawed when compared to algorithmic solutions. Societal pressures on decision makers to produce rational and factual evidence for the... Gerd Gigerenzer goCognitive 00:09:10
When are heuristics superior Against popular belief, there are instances where simple heuristics are not only faster and easier to apply, but they can reliably outperform more complex and exhaustive algorithms. The reason for this is uncertainty of natural environments and the... Gerd Gigerenzer goCognitive 00:06:46
