Why do our headaches persist after taking a one-cent aspirin but disappear when we take a 50-cent aspirin?

Why does recalling the Ten Commandments reduce our tendency to lie, even when we couldn't possibly be caught?

Why do we splurge on a lavish meal but cut coupons to save twenty-five cents on a can of soup?

Why do we go back for second helpings at the unlimited buffet, even when our stomachs are already full?

And how did we ever start spending $4.15 on a cup of coffee when, just a few years ago, we used to pay less than a dollar?

Gabriel Weinberg The books I keep coming back to are the ones where I took away lasting mental models. These include [...] Predictably Irrational (about cognitive bias models). (Source)

Michael Shalyt In the book, Prof. Ariely shows, through a series of experiments, how irrational human decision making really is - but there is order to the madness. Very important read for any engineer/logical thinker who's frustrated with how rash, emotionally driven and seemingly random many decisions seem to be. The book shows that often there is a pattern even if it "doesn't make sense". (Source)

Pedro Cortés To get a good a fulfilling career I believe you need to balance money with your mindset and personal life and for those, I would again recommend the 4hww (to question the 9-5 life), F.U Money (to turn your beliefs about money into good ones), Ego is the enemy (to keep the ego in check), So good they can't ignore you (to adopt the mindset of a craftsman and mastery instead of passion) and Predictably Irrational to be aware of the irrational things you and other people can do so you can adapt to them instead of living your entire life being blinded by them.

Louis Grenier “Incognito: The Secret Lives of the Brain” and “Predictably Irrational” are 2 very good books on psychology that I think you should read. (Source)

Rand Fishkin A phenomenal work from Dan Ariely on why we make seemingly irrational choices. (Source)

Fabrice Grinda I am a believer in gestalt. By reading so many books in so many different genres it helps me get analogies across categories to get a better understanding of how things work. In terms of specifics, I use behavioral economic tricks as presented in books like Predictably Irrational by Dan Ariely in product design, negotiations and presentations. (Source)

Neal O'Gorman Predictably Irrational from Dan Ariely is also an excellent, insightful read. The example for pricing subscriptions for the economist is something every entrepreneur needs to be aware of and look to always apply. (Source)

Radu Marcusu Predictably Irrational is one of my favorite books and also a great resource for marketers to understand how our mind works and how we make buying decisions. I have a thing for behavioral economics lately so maybe that’s why I like it so much. (Source)

Mike Benkovich The title does an amazing job of summing up the entire book. Think you make rational decisions based on logic and reason? Think again! A complete eye-opener that everyone should read. (Source)

Ola Olusoga Like Charlie Munger once said: “I’ve long believed that a certain system - which almost any intelligent person can learn - works way better than the systems most people use [to understand the world]. What you need is a latticework of mental models in your head. And, with that system, things gradually fit together in a way that enhances cognition. Just as multiple factors shape every system, multiple mental models from a variety of disciplines are necessary to understand that system". You can read this book to start building a "latticework of mental models in your head". (Source)

Raluca Radu I work in digital marketing so I would [recommend]: Predictably Irrational by Dan Ariely [...]. (Source)

Gunhee Park Some other books I’ve really enjoyed: [...] Predicatbly Irrational. (Source)

Andra Zaharia 'While I was thinking of the best books to add to this short list, I realized that not even half of them are directly related to digital marketing. This is because I believe that the best marketers are people who understand human nature deeply and aim to bring out the best in it. Call me naive, but that’s how I see it. If I were to want to pursue a career in marketing, I’d read [...] Predictably Irrational. (Source)

Gabriel Coarna Dan Ariely’s Predictably Irrational totally blew my mind. (Source)

Mark Esposito Still to this day, one of the best book on #behavioraleconomics Dan! (Source)

Nick Harkaway Predictably Irrational is an examination of the way in which we make decisions irrationally, and how that irrationality can be predicted. (Source)

Jonah Lehrer Dan Ariely is a very creative guy and was able to take this basic idea, that humans are irrational, and mine it in a million different directions. (Source)
