Daniel Kahneman

Overview

Daniel Kahneman appears in the Wiki as a behavioral-economics bridge between rational-choice models and the context-sensitive behavior of actual consumers and investors. His source role is practical rather than biographical.

Current Profile

Across the represented sources, Kahneman anchors three connected claims. Losses and reference points can shape choice asymmetrically; felt risk is filtered through worldview and experience before it becomes portfolio math; and learning bias vocabulary does not by itself correct behavior. The newest source therefore shifts his practical relevance from diagnosis toward process design: identify repeat-error situations, record reasons before outcomes are known, and evaluate decision quality separately from luck.

Key Characteristics

• Model boundary: the rational-person assumption is useful for analysis but incomplete as a description or life norm.
• Reference-dependent choice: ownership, loss, framing, and context can change economic and investment behavior.
• Risk is felt as well as calculated: personality, upbringing, worldview, and social models shape what an investor can hold.
• Bias literacy is insufficient: naming a bias does not guarantee that the person can suppress it in real time.
• Process can compensate for unreliable intuition: rules, records, and institutional checks can target repeated error situations.

Evidence

• Loss aversion and ordinary choice: 155.美貌能当饭吃吗?想赚钱该做点啥?拮据时应避免什么行为?经济学思维有什么用？ uses prospect-theory-style loss aversion to connect real-money ownership, consumption, and investment behavior.
• Risk perception and worldview: vol.110.投资就是对世界观的投票｜《迈出资产配置第一步》完结篇 routes Paul Slovic’s risk-perception argument through Kahneman and into portfolio suitability.
• Bias knowledge versus behavioral correction: 投资者的敌人：我与我周旋久 invokes Kahneman to argue that knowing many biases does not automatically improve real decisions and recommends situation-specific process controls.

Qualifications

• These sources use Kahneman as an interpretive authority; they do not provide a complete account of his research program, collaborations, or later debates.
• The newest source’s practical recommendations are episode-attributed and should not be treated as a verbatim or comprehensive statement of Kahneman’s own prescriptions.
• Behavioral explanations do not establish that every loss, disagreement, or strategy failure is caused by bias.

What Changed

• The profile now separates bias literacy from successful behavior change.
• Decision logging and process evaluation are added as practical controls against memory rewriting and outcome bias.

Relationships

• Loss Aversion / 损失厌恶 - central behavioral mechanism attached to the represented sources.
• Risk Perception - connects felt danger to worldview and portfolio behavior.
• Behavioral Investing Biases - broader investing application of bias concepts.
• Investment Decision Logging - process control for preserving pre-outcome reasoning.
• Investor Self-Knowledge / 投资者自知 - extends behavioral diagnosis into personal fit and repeated-error awareness.
• Richard Thaler - neighboring behavioral-economics figure in the everyday-economics source.
• Paul Slovic - risk-perception figure linked through the asset-allocation source.
