Book Review: Predictably Irrational by Dan Ariely
You are not as rational as you think you are. Neither am I. That is the entire premise of Predictably Irrational by Dan Ariely, and for investors, it might be the most useful sentence in any book on this shelf.
Published in 2008 and revised and expanded in 2010, Predictably Irrational is one of the founding texts of popular behavioral economics. Ariely’s argument is simple and devastating: human beings do not make random mistakes. We make the same mistakes, in the same directions, over and over, which means our irrationality is predictable, and therefore manageable, once you see it.
If you have ever bought a stock at the top because everyone else was buying, sold at the bottom because the pain got unbearable, or held a loser for years because admitting the mistake felt worse than the loss, this book is about you.

Book Summary
Predictably Irrational walks through a series of experiments, most of them run by Ariely and his colleagues on college students, that expose the hidden forces shaping our decisions. Each chapter takes one force, demonstrates it with a clever experiment, and shows how it leaks into everyday life. The throughline: standard economics assumes we are rational calculators, but we are emotional, comparative, social creatures shaped by context in ways we never notice. The good news is that the patterns are consistent enough to study, and once you know the traps, you can design around them.
Who is Dan Ariely?
Dan Ariely is the James B. Duke Professor of Psychology and Behavioral Economics at Duke University, and one of the best-known popularizers of behavioral economics alongside Daniel Kahneman and Richard Thaler. Predictably Irrational was a New York Times bestseller, and Ariely went on to write several follow-ups, including The Upside of Irrationality and The Honest Truth About Dishonesty.
His interest in the subject was personal: as a teenager in Israel, severe burns put him in hospitals for years, where he became fascinated by how irrationally people behave around pain and decisions. That experience became a research career, and Predictably Irrational is its most readable product.
Lessons From Predictably Irrational
The book is organized around a handful of big ideas. Here are the ones that matter most to investors.
Anchoring and arbitrary coherence. The first number you encounter sets the reference point for everything after it, even when the number is meaningless. Students who wrote down the last two digits of their Social Security numbers before bidding on items bid higher when their digits were higher. Everyone knew the digits were random, and it still worked. Now think about stock prices: the 52-week high is an anchor, and the price you paid is an anchor. Your brain treats them as meaningful reference points, quietly distorting every buy and sell decision. This is why having a valuation framework matters more than having a price target.
The zero-price effect. “Free!” is not just a low price. It is an emotional trigger that shuts down rational comparison. People will choose a free item they do not need over a nearly-free item that is objectively better. Investors do this too: free trades made everyone trade more, and “zero commission” is not zero cost if it turns you into a hyperactive trader. The price of free is your attention and your discipline.
Social norms vs. market norms. The moment money enters a relationship, generosity evaporates and everything becomes transactional. Ariely’s experiments show people will work harder for a favor than for small amounts of cash, because cash moves the interaction into market norms. For investors, the lesson is about advisors, newsletters, and “free” stock tips: once someone is paid to influence your decisions, treat their advice as a market transaction, which it is.
The decoy effect. When choosing between two options, adding a third option that is clearly worse than one of them makes that one look much more attractive. Marketers use this constantly in pricing tiers. In investing, watch for it in fund marketing: the expensive, mediocre fund exists partly to make the slightly-less-expensive one look like a deal. Compare every investment against the alternative of buying the index, not against the decoy sitting next to it.
Ownership and the endowment effect. We overvalue what we own: people demand far more to sell an item they were given than they would pay to buy it. This is the reason investors hold losing positions for years. The stock in your portfolio is not worth more than the identical stock in someone else’s. If you would not buy it today at today’s price, you should not own it today. The endowment effect is the single most expensive bias in this book for a stock picker.
Expectations shape experience. What you expect to taste, feel, or earn changes what you actually experience. Price tags change how much people enjoy wine, and reputation changes how much investors trust a stock. Be skeptical of your own enthusiasm: some of what you “see” in a beloved company is your expectations doing the seeing.
The pain of paying and procrastination. Paying hurts, and we procrastinate on anything with upfront costs and delayed benefits. Ariely’s chapter on self-control, with its experiments on deadlines, applies directly to rebalancing and tax-loss harvesting, the portfolio maintenance investors put off forever. His finding: pre-commitment beats willpower. Automate the good decisions so your future self cannot negotiate out of them.
Work through Predictably Irrational one chapter at a time; it rewards a slow read.

Criticisms of the Book
The fair criticisms of Predictably Irrational have grown louder since it was published, and they deserve a hearing. The biggest is the replication crisis in behavioral economics and psychology more broadly: a number of famous findings in the field have failed to replicate when other researchers tried to reproduce them. Not every experiment in this book has been re-run, and readers should treat individual study results as suggestive rather than settled, even when the broader patterns hold up.
More specifically, questions were raised in 2021 about the data behind a 2012 paper Ariely co-authored on honesty, after an analysis suggested the data had been fabricated. Ariely denied any wrongdoing, said the data had come from an outside company, and noted that he had not collected it himself. The episode does not directly concern this book’s experiments, but it is part of the honest accounting a review should give: some of the shine has come off the field’s early certainty.
A smaller criticism: the experiments were mostly run on college students, and the leap from lab games to real financial decisions is sometimes bigger than the storytelling admits. Take the insights as directionally true, not as laws of physics.
Who is This Book For?
Predictably Irrational is for any investor who wants to understand their own worst enemy: themselves. It pairs naturally with Kahneman’s Thinking, Fast and Slow, the deeper and more rigorous treatment of the same territory, and with Richard Thaler’s Misbehaving, which we reviewed here. If you have read those, this book is the most entertaining entry point of the three, and the experiments make the biases stick in a way abstractions do not.
It is also for anyone who designs choices for a living: marketers, managers, policymakers. But on this site, the audience is investors, and the pitch is simple. Your portfolio’s returns are downstream of your decisions, and your decisions are downstream of biases you cannot feel operating. This book names them. It also sits comfortably on our list of the 7 Best Books on the Psychology of Money.
It is not for readers who want a systematic investing framework. This is a book about how minds work, not about how to value companies.
Final Thoughts
Predictably Irrational will not make you rational. Nothing will. What it does is replace your vague sense that “emotions affect investing” with a specific catalog of traps, each with a name and a countermeasure. Once you can name them, you start catching them in your own brokerage account.
The replication concerns are real, and this review would be dishonest without them. But the book’s core message has survived the field’s troubles intact: your mistakes are not random, they are systematic, and systematic mistakes can be managed. For an investor, that is one of the highest-leverage insights in print.

Words Change Behavior More Than We Think https://www.powerofusnewsletter.com/p/shaping-behavior-with-language
Challenging the standard consequentialist assumption that decision-making is driven solely by outcomes and incentives, Capraro argues that #behavioralEconomics must integrate linguistic framing directly into formal models of choice. Powered by #AI's capacity to quantify semantic nuance, he contends that “large language models can facilitate a paradigm shift within behavioural economics from outcome-based utility functions to a more general class of functions that better describe human behaviour.”

💰 LES RICHES MÉRITENT-ILS LEUR ARGENT ?
Attendez.
Ne répondez pas.
Parce que la question est beaucoup plus intéressante qu'elle en a l'air.
Imaginons plutôt une expérience.
Je prends plusieurs centaines de personnes.
Et je crée une petite société.
Certains auront 50 jetons.
D'autres en auront 100.
Il y aura donc des « pauvres ».
Et des « riches ».
Mais il me reste une décision à prendre.
Pourquoi certains auront-ils deux fois plus que les autres ?
━━━━━━━━━━━━━━
🎲 PREMIÈRE POSSIBILITÉ : LE HASARD.
Vous tombez du bon côté ?
100 jetons.
Du mauvais ?
50.
Vous n'avez rien fait pour le mériter.
C'est simplement votre chance.
Pas très juste.
Alors essayons autre chose.
━━━━━━━━━━━━━━
🏆 DEUXIÈME POSSIBILITÉ : LE MÉRITE.
Cette fois, les participants accomplissent une tâche.
Leur performance détermine leur position.
Les meilleurs obtiennent davantage.
Les autres moins.
Même inégalité.
50 jetons.
100 jetons.
Mais cette fois…
il existe une raison.
Et quand les chercheurs demandent aux participants ce qu'ils pensent de ces systèmes…
le résultat paraît assez intuitif.
Le système fondé sur le mérite est considéré comme plus juste que celui fondé sur la chance.
Très bien.
Maintenant que nous avons construit notre petite société…
faisons quelque chose de beaucoup plus intéressant.
Faisons-les jouer ensemble.
━━━━━━━━━━━━━━
🤝 PREMIER JEU : LA CONFIANCE.
Vous pouvez confier une partie de votre argent à quelqu'un.
Vous prenez donc un risque.
Est-ce qu'il vous rendra quelque chose ?
━━━━━━━━━━━━━━
🦌 DEUXIÈME JEU : LA COORDINATION.
Vous pouvez choisir une stratégie sûre…
ou tenter une stratégie beaucoup plus avantageuse si l'autre personne fait la même chose.
Mais pour ça…
il faut croire qu'elle coopérera.
━━━━━━━━━━━━━━
⚔️ TROISIÈME JEU : LE DILEMME DU PRISONNIER.
Coopérer peut profiter aux deux.
Trahir peut profiter à celui qui le fait.
Vous connaissez probablement la chanson.
Nous avons donc maintenant :
des riches.
des pauvres.
du mérite.
de la chance.
de la confiance.
de la coopération.
Et surtout…
de l'argent réel en jeu.
Alors faisons une prédiction.
Si les participants trouvent l'inégalité fondée sur le mérite plus juste…
ils devraient peut-être aussi davantage se faire confiance dans ce système.
Logique ?
C'était justement l'une des hypothèses des chercheurs.
━━━━━━━━━━━━━━
💥 ELLE NE S'EST PAS VRAIMENT VÉRIFIÉE.
━━━━━━━━━━━━━━
Le mérite était bien perçu comme plus juste.
Mais cette perception ne s'est pas transformée en davantage de confiance.
Plus étrange encore :
dans leurs analyses, les chercheurs trouvent au contraire davantage de confiance lorsque l'inégalité provenait de la chance.
Pas du mérite.
Et lorsque les chercheurs comparent plus largement sociétés égales et sociétés inégales…
l'inégalité laisse également des traces.
Moins de fiabilité dans le jeu de confiance.
Moins de coordination vers la solution collectivement la plus avantageuse dans le jeu de la chasse au cerf.
Tout n'a pas diminué.
La coopération dans le dilemme du prisonnier, notamment, ne montre pas le même effet clair.
Et c'est précisément ce qui rend le résultat intéressant.
━━━━━━━━━━━━━━
🧠 PARCE QUE L'EXPÉRIENCE NE DIT PAS :
« LE MÉRITE EST MAUVAIS. »
Elle ne dit pas :
« LES RICHES NE MÉRITENT PAS LEUR ARGENT. »
Et elle ne démontre certainement pas :
« LE #CAPITALISM NE FONCTIONNE PAS. »
Ce serait transformer une expérience contrôlée en slogan politique.
Elle montre quelque chose de beaucoup plus précis.
Nous pouvons considérer un système comme plus juste…
sans que ce sentiment de justice produise automatiquement davantage de confiance ou de coordination entre ceux qui y vivent.
━━━━━━━━━━━━━━
Et maintenant…
revenons à la question du début.
💰 « Les riches méritent-ils leur argent ? »
C'était le leurre.
Cette expérience ne permet absolument pas d'y répondre.
Parce que la question intéressante n'était pas de savoir qui « mérite » quoi.
Elle était de savoir ce que notre perception du mérite change dans notre comportement envers les autres.
Et manifestement…
« c'est juste »
et
« je te fais confiance »
ne sont pas deux façons de dire la même chose.
━━━━━━━━━━━━━━
🔎 Nous pouvons accepter les règles d'un jeu…
sans que ces règles nous rapprochent les uns des autres.

#Nudge or #tax? At last, some data https://timharford.com/2026/09/nudge-or-tax-at-last-some-data/
"the two approaches complement each other. Take vaccination: a government keen to maximise the uptake of a vaccine would do well to reduce the price (zero is a particularly attractive price point, it turns out) but should also send out well-timed and well-phrased reminders. There is nothing mutually exclusive about these options.
…
If the choice is between the icing and the cake, politicians should choose the cake. Nudges are far from trivial in their benefits, but there is no substitute for using taxes to get price signals right. List et al write: “In four of five markets, price instruments deliver substantially larger total surplus than nudges.”All too often, politicians are turning their back on the most beneficial policies because they lack the political courage or the political skill to introduce them."

7 Best Books on the Psychology of Money
Most investors know what they should do. Spend less than they earn. Buy index funds. Hold through downturns. Few actually do it. The gap between knowing and doing is not a knowledge problem. It is a psychology problem.
Behavioral economists have spent decades mapping that gap, and a small shelf of books explains their findings in plain language. These are the seven most useful, ranked by how much they change the way you handle your own money.
1. The Psychology of Money by Morgan Housel
Morgan Housel is a partner at the Collaborative Fund and a former Wall Street Journal columnist. His argument is simple: doing well with money has surprisingly little to do with how smart you are and a lot to do with how you behave. The book’s central ideas are that wealth is what you don’t see (it compounds through restraint, not displays), that knowing when you have ‘enough’ is the hardest financial skill, and that everyone’s money decisions make sense to them given their own history — so judging others’ choices is usually a mistake. Read it alongside Who is Morgan Housel? and his follow-up Same as Ever. The Psychology of Money (2020) is the best starting point on this list.
2. Thinking, Fast and Slow by Daniel Kahneman
Daniel Kahneman, the Nobel-winning psychologist, describes two modes of thought: fast, intuitive System 1 and slow, deliberate System 2. Investing is a System 1 minefield. Overconfidence makes us trade too much. Loss aversion makes us sell winners early and ride losers down. Anchoring makes the first price we see feel like the ‘right’ one. The book is dense, but no other single work explains why smart people make dumb money decisions. Our review of Thinking, Fast and Slow covers the key experiments. Thinking, Fast and Slow (2011).
3. Nudge by Richard Thaler and Cass Sunstein
Richard Thaler and Cass Sunstein argue that small changes in how choices are presented — ‘choice architecture’ — steer people toward better decisions without restricting their freedom. The famous example is automatic enrollment in 401(k) plans, which raised participation far more than any education campaign. The lesson for your own finances: design your defaults so the right behavior is the easy one. Automate savings, automate investing, and let inertia work for you instead of against you. Our review of Nudge has the details. Nudge (final edition, 2021).
4. Misbehaving by Richard Thaler
This is Thaler’s intellectual memoir of how behavioral economics was built. He documents the ‘misbehaving’ humans — including himself — who failed to match the rational models of classical economics: people who treat money differently depending on mental accounts, who overvalue what they own (the endowment effect), and who throw good money after bad because of sunk costs. It reads as a story rather than a textbook, which makes it the most enjoyable entry point to the academic research behind this list. Our review of Misbehaving. Misbehaving (2015).
5. Thinking in Bets by Annie Duke
Annie Duke is a former professional poker player who applies the poker mindset to everyday decisions. Her core insight: every decision is a bet on an uncertain future, and good decisions can still produce bad outcomes. Judging a decision by its result — ‘resulting’ — is the most common thinking error she sees. The fix is practical: state your beliefs as probabilities, keep a decision journal, and find a group that will argue with you honestly. Investors who internalize this stop confusing luck with skill. Who is Annie Duke? and our review of Thinking in Bets. Thinking in Bets (2018).
6. Just Keep Buying by Nick Maggiulli
Nick Maggiulli, a data scientist at Ritholtz Wealth Management, answers personal finance questions with data instead of anecdotes. Why you need to save less than you think. Why waiting for dips costs more than it saves. How to survive a market crash. The psychology angle is implicit throughout: your feelings about money are unreliable, so build rules that don’t depend on them. Who is Nick Maggiulli? and our review of Just Keep Buying. Just Keep Buying (2022).
7. The Art of Spending Money by Morgan Housel
Housel’s 2025 follow-up turns from saving to spending — the half of money psychology most books ignore. The argument: money’s highest purpose is buying control over your time and optionality, but expectations, not income, determine whether spending actually satisfies. People confuse envy with admiration, chase benchmarks that move, and forget that the point of wealth was never the wealth itself. It is the natural companion to the first book on this list. The Art of Spending Money (2025).
How to Use This List
You do not need to read all seven. Start with The Psychology of Money if you are new to the subject; it is the shortest path to thinking differently. Add Thinking, Fast and Slow when you want the science, and Nudge when you want to redesign your own habits. The practical move is to take one idea from each book you read and turn it into a rule: automate your savings (Thaler and Sunstein), write down your reasons before any large financial decision (Duke), define ‘enough’ in writing (Housel). Loss aversion alone explains most of the mistakes on that list, and naming it is the first step to working around it.
The uncomfortable truth these books share is that investment returns come mostly from behavior, not from picking the right assets. The market rewards patience, humility, and consistency — all psychological traits, none of them purchasable. A bookshelf that trains those traits is worth more than a better stock screener.

Tired of being constantly ‘nudged’? I know I am. Text, email, robocall reminders & notifications - from everyone all the time. Blame #BehavioralEconomics. It’s all about compliance engineering. Read the Wikipedia note:
“The first formulation of the term nudge and associated principles was developed in cybernetics by James Wilk before 1995 and described by Brunel University academic D. J. Stewart as "the art of the nudge". It also drew on methodological influences from clinical psychotherapy tracing back to Gregory Bateson... In this variant, a nudge is a microtargeted design geared toward a specific group of people, irrespective of the scale of intended intervention. In 2008, Richard Thaler and Cass Sunstein's book Nudge: Improving Decisions About Health, Wealth, and Happiness brought nudge theory to prominence. The authors refer to the influencing of behaviour without coercion as libertarian paternalism and the influencers as choice architects.” https://en.wikipedia.org/wiki/Nudge_theory?wprov=sfti1 #nudge #NudgeTheory #compliance

Book Review: Misbehaving by Richard Thaler
Most personal finance advice assumes you are a rational actor. Save more than you spend. Invest early. Avoid debt. The logic is airtight. So why is it so hard to follow?
Misbehaving: The Making of Behavioral Economics by Richard Thaler argues that the problem isn’t a lack of information. It’s that humans are not the rational, self-interested agents that classical economics assumes we are. We are emotional, distracted, and predictably irrational. Understanding that about yourself is, oddly enough, one of the most practical things you can do for your finances.
Book Summary
Published in 2015, Misbehaving is part memoir, part manifesto for a field that Thaler helped build from the ground up. The book traces the history of behavioral economics, a discipline that blends psychology and economics to explain why people make the financial decisions they actually make rather than the ones they theoretically should.
Thaler walks readers through decades of research, much of it conducted alongside collaborators like Daniel Kahneman and Amos Tversky. He introduces concepts like mental accounting, the endowment effect, and present bias, and shows how each one leads ordinary people to make financial choices that undermine their own goals. The book is accessible, often funny, and grounded in real-world examples ranging from the NFL draft to retirement savings behavior.
Who Is Richard Thaler?
Richard Thaler is a professor of behavioral science and economics at the University of Chicago Booth School of Business. He is widely regarded as one of the founding figures of behavioral economics and won the Nobel Memorial Prize in Economic Sciences in 2017 for his contributions to the field.
Thaler is also co-author, with Cass Sunstein, of Nudge, a book that applies behavioral economics to public policy and became influential in government circles around the world. His academic work spans loss aversion, intertemporal choice, and the psychology of decision-making under uncertainty. He is not a self-help guru or financial advisor. He is a researcher who spent decades trying to convince economists that real human behavior matters.
Key Lessons from the Book
Misbehaving is dense with insight, but a few lessons are particularly relevant to anyone trying to build better money habits.
The first is mental accounting. Thaler demonstrates that people treat money differently depending on where it came from or where it is mentally categorized. A tax refund feels like a windfall and gets spent freely, even though it’s the same money you earned throughout the year. Recognizing this tendency can help you make more deliberate decisions about how you allocate funds rather than letting psychological framing do it for you.
The second is the endowment effect. Once you own something, you value it more than you would if you didn’t own it. This has real implications for investors who hold losing positions too long because selling feels like a loss rather than a correction.
The third is present bias. People consistently overvalue what they can have right now versus what they could have in the future. This is one of the core reasons that saving for retirement is so psychologically difficult even when the math makes it obviously worthwhile. Thaler’s research contributed directly to the design of automatic enrollment in 401(k) plans, which work precisely because they use inertia to overcome present bias rather than fighting it.
The broader lesson is structural: if you design your financial life to account for your psychological weaknesses rather than pretending they don’t exist, you are more likely to succeed. Automating savings, using a high-yield savings account for your emergency fund so you’re at least earning something while the money sits, and setting up automatic investments into an S&P 500 index fund are all practical applications of this thinking. The system does the work so your in-the-moment self can’t undermine your long-term self.
Criticisms of the Book
Misbehaving is not without its weaknesses. The most common criticism is that the book is too long and self-congratulatory in places. Thaler spends considerable time recounting his own battles to get behavioral economics accepted within mainstream academia, and while that history is interesting, it can feel indulgent. Readers looking for a tighter read focused purely on actionable lessons may find the pacing uneven.
Some critics have also pointed out that behavioral economics, despite its insights, can be used paternalistically. Knowing that people are susceptible to nudges is a double-edged tool. Governments and corporations can use the same techniques Thaler champions to steer people toward outcomes that benefit institutions rather than individuals.
Finally, the book is stronger on diagnosis than prescription. Thaler is very good at explaining why people make bad decisions. He is less focused on giving readers a step-by-step framework for changing their behavior. Readers expecting a personal finance manual will need to do some of that work themselves.
Should You Buy This Book?
Yes, particularly if you have ever wondered why you know what you should do with your money but struggle to do it. Misbehaving gives you a vocabulary and a mental model for understanding the gap between intention and action. That understanding is genuinely useful.
It pairs well with other foundational books in the behavioral and personal finance space. If you have read Thinking, Fast and Slow by Daniel Kahneman, Misbehaving is a natural complement. If you haven’t read either, Kahneman’s book may actually be the better starting point, as it covers the psychological foundations in more depth. But Thaler’s book is more personal, more narrative, and more focused on economics specifically.
If you are looking for a book that changes how you think about your own financial decision-making, Misbehaving is worth your time and the cost of the book.
Final Thoughts
The central argument of Misbehaving is simple and important: people are not rational, and pretending otherwise leads to bad policy, bad financial products, and bad personal outcomes. Thaler spent his career making that case within a discipline that initially resisted it, and the Nobel Prize suggests he was right.
For anyone interested in money, budgeting, and learning how psychology shapes financial behavior, this book belongs on the shelf. It won’t give you a budget template or a specific investment strategy. What it gives you is something more durable: a clearer picture of the mind you’re working with every time you make a financial decision.

How Your #Brain Decides What Matters
https://nautil.us/how-your-brain-decides-what-matters-1281159
Traditional #neuroscience mythologized the amygdala as a simple fear switch, but recent studies on a rare genetic disorder reveal its deeper role in social and economic decision-making. Rather than just detecting threats, the basolateral amygdala acts as "...a kind of social compass, helping to weigh the needs and intentions of others and decide who matters to us." When this neural circuitry is damaged, individuals fail to properly balance risk and reward, displaying "...a diminished ability to flexibly weigh uncertainty, self-interest, and the intentions of others." This computational deficit often manifests as extreme generosity to strangers, demonstrating "...a willingness to help others without the usual filtering of context." Complex social choices rely on this vital brain region to "...integrate self-interest with concern for others into a single signal that guides behavior."

Being ill/unmotivated is giving me a chance to catch up on Jon Stewart's Weekly Show podcast. At the end of his Oren Cass show he says he got a lot of hate for his performance with Richard Thaler. I like Thaler so I am now listening to the show to see what went down. Oh boy Jon, listen you oaf! You're not giving Richard a chance to make his points and so you never got to learn anything. 100% you deserved the shit you got. Also I think he successfully wrangled you and took the piss out of you which made the show fun despite its problems.
Final Score:
Jon Stewart 0
Richard Thaler 1 -

One Sentence at a Time: A Quantitative #History of Rationality in Economic Thought https://d.repec.org/n?u=RePEc:osf:socarx:38na2_v1&r=&r=big
"… Combining large language model–based semantic analysis with bibliometric and network methods, we identify and cluster discussions of #rationality across time and scales, such as the circulation of #boundedRationality and the emergence of #behavioralEconomics."

New name, new focus: the Max Planck Institute for Collective Goods is now the Max Planck Institute for Behavioral Economics. This name change reflects the research conducted in Bonn very nicely. 👍 www.coll.mpg.de

Why can't you start?
Because your brain sees 47 tasks and freezes. Psychologists call it choice paralysis.
THIS. shows you one task. Just one. That's the whole app.

How do monetary incentives affect the measurement of social preferences? https://d.repec.org/n?u=RePEc:zur:econwp:482&r=&r=exp
"… the use of monetary #incentives, as well as the size of the stakes, have little impact on choices at the descriptive levels, as well as for the identification of qualitatively distinct preferences types. They appear to matter, however, for the quantitative identification of the strength and the precision of social preferences.
… the #socialPreferences of the general population are likely overestimated when elicited with hypothetical stakes. If one is solely interested in having a rough, descriptive measure of social preferences at the aggregate level, or if one wants to identify qualitatively distinct preferences types, then relying on hypothetical stakes might suffice.
… if one is interested in making a quantitative assessment of subjects’ other-regardingness, e.g., in order to make quantitative predictions, then our result suggest that using monetary incentives is advisable,
… no evidence that using a larger stake size improves the identification of social preferences"

How Scrutiny and Iteration Made Behavioral Economics Better https://www.chicagobooth.edu/review/how-scrutiny-iteration-made-behavioral-economics-better
"However, direct #replicability should not be confused with #generalizability or universality. While the basic patterns of behavior documented in the original experiments reliably show up in subsequent replications, their magnitudes can vary substantially across contexts. Loss aversion might be stronger in some settings than in others. Understanding this variation has become a central focus of contemporary behavioral economics research. Rather than viewing such #heterogeneity as a challenge to the field’s foundations, researchers increasingly see it as a source of insight into the underlying psychological mechanisms driving behavioral anomalies."

As Java architects, we often see great technical ideas die in boardrooms. Why? Executives don’t think in code — they think in risk, timing, and narrative.
I’ve written about the psychology that shapes their decisions — and how we can adapt:
