Original Title:

TL;DR

Intuition, defined as fast, experience-based feelings without explicit explanation, is a crucial cognitive tool for innovation and decision-making, not an arbitrary or exclusively feminine trait.
The historical dichotomy of intuition as feminine and reason as masculine has led to a mischaracterization of cognitive processes, obscuring the fact that intuition and conscious thought are complementary.
Overemphasis on "bias bias" overlooks ecological rationality, wrongly labeling many heuristics as errors when they are adaptive responses to uncertainty and complexity.
Boosting, which empowers individuals with risk literacy and understanding, is a more democratic and effective approach than "nudging," which risks 21st-century paternalism.
AI, while capable in well-defined domains, currently struggles with uncertainty and human-like intuition, making techno-optimistic claims of its problem-solving universality unfounded.
The effectiveness of policies like organ donation defaults is often overestimated, as actual outcomes depend on complex systemic organization rather than mere opt-in/opt-out mechanisms.
Communicating medical screening benefits using relative rather than absolute risk deceives individuals, obscuring minimal life extension and potential harms, thereby serving commercial interests over informed consent.

Deep Dive

Intuition, often dismissed as irrational or feminine, is a powerful, experience-based cognitive tool that complements, rather than opposes, conscious thinking, and its underestimation has led to flawed policy and a mischaracterization of human decision-making, particularly in fields like artificial intelligence and risk assessment. The prevailing narrative, influenced by a "bias bias," overemphasizes human irrationality, justifying paternalistic interventions like "nudging" instead of empowering individuals through "boosting."

The tendency to view intuition as a lesser form of cognition stems from a historical dichotomy that associated men with rationality and women with intuition, a flawed premise that has persisted into modern psychological frameworks like System 1 and System 2 thinking. Psychologist Gerd Gigerenzer argues that this dichotomy is a mistake, asserting that intuition--a rapid feeling based on years of experience that defies easy explanation--is not arbitrary but a crucial component of intelligence. This is exemplified by doctors who develop an intuitive sense for a patient's condition, which then guides deliberate diagnostic processes. Similarly, innovation and discovery often arise from intuitive leaps that conscious reasoning then validates or refines.

This re-evaluation of intuition has broad implications, particularly for the discourse surrounding artificial intelligence (AI). The relentless techno-optimism surrounding AI often overstates its capabilities, portraying it as a panacea for complex human problems like poverty or disease. Gigerenzer cautions that while AI excels in well-defined domains like chess or Go, it struggles with the uncertainty and nuance inherent in human behavior and prediction, a limitation often masked by funding pressures and an overreliance on technological solutions. The human genome project, once hailed as a cure-all, serves as a cautionary tale: understanding genetic code did not automatically translate to cures due to the complex interactions involved, a parallel Gigerenzer draws with AI's current limitations in addressing intricate issues.

Furthermore, the prevalent critique of human "biases," termed the "bias bias," misinterprets many decision-making heuristics as inherent irrationality. Gigerenzer contends that what are often labeled as biases, such as overconfidence or the framing effect, are in fact adaptive strategies contingent on the environment. For instance, overconfidence can be beneficial in rapidly changing situations, while framing effects can be understood as nuanced communication, not mere logical errors. This perspective challenges the foundation of "nudging"--policies designed to steer individuals by exploiting perceived irrationalities--advocating instead for "boosting," which aims to enhance individuals' understanding and capabilities, such as risk literacy. The distinction is critical: nudging treats people as predictable automata to be guided, while boosting empowers them as informed agents capable of making their own decisions.

The limitations of nudging are starkly illustrated by organ donation policies. While opt-out systems demonstrably increase potential donors, they do not significantly raise actual donation rates because the underlying logistical and organizational challenges of collecting organs remain unaddressed. This highlights that effective policy requires addressing systemic complexities, not merely manipulating defaults. Similarly, the communication of medical screening benefits, such as mammography, often relies on misleading relative risk figures that obscure the minimal absolute gains and significant harms, effectively nudging individuals into procedures without full comprehension. Gigerenzer argues that true progress lies in prevention--addressing behavioral factors like diet and exercise--rather than relying on potentially counterproductive screening and paternalistic interventions.

Ultimately, Gigerenzer's work suggests a profound shift in how we understand intelligence, decision-making, and societal progress. By recognizing the validity and power of intuition and ecological rationality, and by moving from paternalistic nudging to empowering boosting, societies can foster more informed, capable individuals and build more robust, democratic systems. This requires a commitment to intellectual honesty, a willingness to challenge prevailing narratives, and a conscious effort to cultivate critical thinking, even within scientific communities, by embracing contrarian viewpoints and fostering environments where ideas can be rigorously tested and revised.

Action Items

Audit AI capabilities: Identify 3-5 core tasks where current AI exhibits limitations due to lack of intuition or real-world understanding (e.g., complex social problems, nuanced human interaction).
Create risk literacy curriculum: Design a 1-day workshop for 10-15 participants on understanding conditional probabilities and base rates using frequency formats.
Implement "contrarian" review process: For 2-3 critical projects, assign a team member to respectfully challenge assumptions and findings before finalization.
Develop "boosting" communication framework: Draft guidelines for presenting information (e.g., medical test results, weather forecasts) to empower users with understanding, not just influence decisions.

Key Quotes

"True intuition is a feeling based on years of experience that comes fast into your consciousness so you feel what you should do or what you shouldn't do and the way you have no way to explain it where it's coming from so it is uh it is not an arbitrary decision it is not uh a seventh or sixth sense depending on how you count the senses and it's not something that only women have so everyone has intuition who has experience with a certain uh domain or task."

Gerd Gigerenzer defines intuition as a rapid, subconscious feeling derived from extensive experience, which is not explainable but also not arbitrary. Gigerenzer clarifies that intuition is not a mystical sense and is accessible to anyone with domain-specific experience.

"The bias bias is the temptation to see biases everywhere even if there are none and that is mostly to to researchers, but also to many people who want to use this to justify their policies like nudging, political paternalism, and artificial intelligence paternalism. The argument is people have all these biases, machines can do better. What do you want? Believe in machines."

Gerd Gigerenzer introduces the concept of the "bias bias," which he describes as an overemphasis on identifying biases, often by researchers and policymakers. Gigerenzer argues that this perspective is used to justify paternalistic policies, suggesting that because people are supposedly biased, they should defer to machines or experts.

"Boosting means that you make people strong, you don't nudge them like sheep, you make them stronger and they can start already in in schools make them risk literacy and that should continue in journalism rather than going and for instance or in the parties that you mentioned yeah cocktail parties rather than telling stupid stories about how dumb everyone else is and laugh. Why don't you tell a few stories how to understand things how to understand what a positive test you have a positive COVID test does it mean that you have COVID? No, what's the chance? Figure it out."

Gerd Gigerenzer contrasts "boosting" with "nudging," advocating for the former as a method to empower individuals. Gigerenzer explains that boosting involves educating people, starting from a young age, in areas like risk literacy, enabling them to understand complex information and make informed decisions.

"The problem is much bigger than a default and the these the two big studies that have been out the one the O.E.C.D studies and the second one done at the Max Planck Institute for Human Development where I am had looked at countries that actually switched from everyone is not a donor except the person opts in to everyone is a donor except the person opts out and have looked what happens the number of potential donors increases yes but the number of actual donors did not increase and the reason is simple because the system is not being changed."

Gerd Gigerenzer uses the example of organ donation policies to illustrate that defaults, such as opting in or opting out, do not significantly increase actual organ donations. Gigerenzer points out that while potential donors may increase, the real challenge lies in the underlying organizational systems, which are not addressed by simply changing a default setting.

"The answer is from randomized trials the best thing we have and the answer is mammography screening prolongs life by zero days zero and that's on average obviously it's always dependent on what age you are when you get the screening what the policy of the country is what your personal history is this is not a show about medical advice but it's illustrative of an important point carry on but women are deceived into that so this information is not passed on you find this in uh in the last large review in JAMA and women are told there's a 20 reduction of breast cancer mortality and that's if they get if they get mammograms yes yeah and that's a form of nudging."

Gerd Gigerenzer critiques mammography screening, stating that randomized trials show it prolongs life by zero days on average, despite common communication of a 20% reduction in mortality. Gigerenzer argues that this is a form of nudging, where relative risk is used to persuade women into screening without fully disclosing the absolute risk or potential harms.

"The business of doing science, that you revise your ideas and that's hard to do though science I must say I learn all the time and and my research group at the Max Planck Institute is deliberately not has never been a group of so it's typically was about 30 to 35 researchers and they're not been enough from about a dozen different disciplines and it's deliberate so that there's always someone who knows more about something that I know and there's always someone from whom I can learn."

Gerd Gigerenzer emphasizes the importance of continuous learning and revision in science, highlighting the deliberate diversity of his research group. Gigerenzer explains that having researchers from various disciplines ensures that there are always individuals with more knowledge, facilitating learning and correcting potential biases within the group.
