"THIS. This is the right book for right now. Yes, learning requires focus. But, unlearning and relearning requires much more--it requires choosing courage over comfort. In Think Again, Adam Grant weaves together research and storytelling to help us build the intellectual and emotional muscle we need to stay curious enough about the world to act

In 1933, the philosopher Bertrand Russell wrote that “the fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.” While this is just as true today as it was in the early twentieth-century, the problem actually runs deeper; almost everyone recognizes arrogance and overconfidence in others—but never in themselves.

Since the time of Russell, what’s become known as the Dunning-Kruger Effect has been experimentally validated. Resea

Once again, Adam Grant releases a book that solidifies him as one of my favorite psychology writers. I didn't really know what this new book was about before it launched, but I love Grant's writing. Once I started reading it, I ended up binging the book in a day. This book is all about one of my favorite subjects, which is intellectual humility. In Think Again, Adam Grant challenges us to become alright with not knowing, being wrong, and rethinking our own conventional wisdom. Our egos hate when ...more

The first rule of the Dunning-Kruger club is that you don't know you are a member of the Dunning-Kruger club.

Think this ^ doesn't apply to you? > Think again :).

Are you really so certain you are a "Democrat", a "Tory", a "Labor" voter or a "Republican"?

Really? So, you have "the" answer? Or, could it be that parties themselves are in fact the problem you hope to resolve as they part 'us' against 'them'. Will your version of division truly help stop the division?

If you are oh so certain you don't

I’m still a huge Yankees fan but now have a little more appreciation for Red Sox fans (not much though) ⚾️

Think Again is a hefty collection of useful social psychology research well summarized and presented for the layperson interested in challenging how we think and why we think the way we do.

“Think Again” by American psychologist, bestselling author and professor of organizational psychology at the Wharton Business School, Adam Grant, is known wisdom repackaged efficiently and repurposed expertly. The nub of Grant’s latest book is rethinking the art of thinking. Received wisdom, stale conventions and entrenched dogmas have, according to Grant not just permeated our thoughts but have also succeeded admirably well in influencing our very approach to both personal and professional live ...more

Adam Grant's Think Again is a solid book extolling the benefits of open-mindedness and reassessing your beliefs. He uses a nice blend of research-backed insights and anecdotal evidence to walk the reader through how to use uncertainty and the knowledge of not knowing to both convince others and reevaluate your own beliefs.

Grant defines three archetypes to represent the most common mistakes people make when attempting to convince others: Preacher, Prosecutor, & Politician. When we become a preac

Torn between a 4 and a 5 so let’s settle for 4.5. This is definitely one of the most insightful psychology books I’ve read—not overly repetitive or common-sense, and I already know that everything I learned will be extremely applicable to all areas of my life, from professional to personal. The book covers rethinking and unlearning (or modifying your values and opinions based on new facts), which I find extremely relevant in the current political climate as well as in life in general. Grant does ...more

The topic of Adam's book, The Power of Knowing What You Don't Know, has given me immense validation that it's okay to rethink decisions. I rethink every decision I make because I am constantly changing plans. The author points out that sometimes, the first place we start—our first thoughts and our intuitions—are always our best thoughts. I loved when the author talked about kids being asked what they want to be when they grow up. Instead of asking something we know will probably change or evolve ...more

The book is highly relevant for today's times, in the massive rise of internet warriors and increased polarisation, its so hard to make an opinion based on the truth amidst sensationalized news. Most of our baseline opinions are arbitrary, we have developed them without any rigorous data or deep reflections, which is where the concept of 'thinking like a scientist' can be so useful. Instead of quickly forming an opinion, treat it like a hypothesis and test it with data. Asking people questions l ...more

Well written, clear, engaging and hilarious - this book has been an enjoyable and extremely valuable read for me. I initially purchased the audiobook because Adam Grands reads it and it feels like a long podcast. What a FANTASTIC writer AND narrator he is! He masterfully opens some of your blind spots and motivates you to rethink our beliefs and assumptions we have from decades about different things. Seriously, be prepared for your life to be changed after reading this! I found the science in t ...more

Caveat: I'm probably not the target audience for this book. Saw 0 new arguments here, and also saw a lot of badly designed studies being masqueraded as "data-driven proof". Will not recommend – specially if you're an engineer, computer scientist or investor – and are in an environment where you're constantly seeking evidence that you're wrong and can do things better

Ray Dalio's Principles is Taleb's Skin In the Game are far better books if you're looking to understand what it is that you do not

This book by Wharton professor came out at 3 am and I waited to finish it before going to bed. His best book so far.

Top takeaways:
—Being curious and open are the vital characteristics of a national leader or a life saving firefighter!
—Best forecasters are the ones who change their minds many times even if they don’t like what they are changing their mind to. (Like the forecaster who predicted Trump’s victory when his chances was 8% of winning the primary according to Nate Silver)

For fans of "Originals" and "Give and Take", this book will probably satiate your craving for more of Adam Grant's brand of distilling social science into a highly engaging, eminently readable book. It's a pretty breezy read, and shorter than his others if I'm remembering correctly. But that doesn't mean it's not packed full of insights delivered in that eye-opening, AHA way that Grant so excels at. The book's core message is one of humility. He encourages us to stop, ask how we know what we thi ...more

As a person who likes to affirm that she's always right, I really needed this book. Besides, it was on my must-read 2021 releases list. Adam Grant is very practical in his directness, which I always appreciate in this kind of non-fiction. "Think again" is the perfect combination of explanatory and practical. Grant explains some concepts, but always with examples and tips, sometimes from his own life. As a teacher, I specially appreciated the chapter on how teachers can rethink their passiveness ...more

Some of the book's key takeaways:

-Always challenge your knowledge and perspective by re-learning, researching, and testing your hypotheses.

-Think about the different times. What worked in the past might not work today. What works today may not work in the future. What is impossible today may be possible in the future.

-Don’t fall into confirmation bias and desirability bias. Don’t stop unbelieving.

-Knowledge makes people confident. But don’t be overconfident. Have the humility to realize that the

I am a bit in a stretch on this one.

First - I did complete it in one sitting. To the point without any major waste of words or repetitions and very, very engaging.
What is in the hindsight less fascinating is it´s core message: or the web of it´s core messages. Will need to do a lot of thinking and rethinking on it (which is great), but in the end I feel now that there is inherent weakness in hailing the "scientific approach" (as defined by author) as the main way of approaching problems: as a mo

I don’t mean to be dramatic, but this is my favorite book of all time (thus far, anyway). I love books that make me rethink every life choice I’ve ever made. Adam Grant’s Think Again is Malcolm Gladwell on steroids. It is a beautiful masterpiece of intellectual curiosity and open-mindedness and a push to re-evaluate absolutely everything. The book’s primary contention is that we walk through life with a set of beliefs about how the world works and how we are to function in it and this is severel ...more

I’m a newcomer to Grant and read this after seeing it in the UPenn bookstore. Actually after my wife saw it and I kind of eye rolled like, “Some blah blah blah Wharton pop Econ psychology bullshitter book that the bookstore has to push.”

Grant won me over though. The topic is an echo chamber to my own natural second guessing of everything I believe all the time and my own changeable mind. For verification that being that way doesn’t make me weak-minded, thank you Adam Grant. And sure it’s pop fee

This book checked all the boxes for me when it comes to nonfiction. Practical, informative, and open to change. The book successfully practices what it preaches - or should I say "rethinks like a scientist" instead of preaches? The anecdotes successfully keep the reader's interest while serving as the main vehicle for the author's key claims. I think the lessons in this book would benefit anyone! ...more

I really enjoyed this, although I was hoping for more hands-on advice, or exercises.
Overall the book goes through different areas of life from the perspective of rethinking. How an ability to rethink can be beneficial in life and work, how it is hard to change other people's beliefs and get them to rethink. How we ourselves may not be as good at rethinking as we think.
Everything was well presented and supported by examples and experiments/studies. I much enjoyed how he didn't just pretend that h

Many academics do interesting research. Some can express themselves clearly. Then there are those who can synthesize their work, make you think, and write a compelling text.

Adam Grant is one of those people.

Think Again isn't your normal psychology text. Yes, Grant cites plenty of studies, but stitches them together into a fascinating narrative about why we're so loath to change our minds. I particularly enjoyed the book's figures, cartoons, and even flow charts—all of which vividly illustrates

If you're an overthinker, this book will make you feel less guilty about taking the time to see things from different perspectives. You will actually learn how to gain more benefits from doing that. I don't recommend this to super-anxious people who might exaggerate some ideas from this book.

Read the essence of Think Again in 60 seconds - recommended by “Think Again is a must-read... In an increasingly divided world, the lessons in this book are more important than ever.” #Bill _Melinda_Gates


True measure of service?

Unreasonable attributes shape the world ?

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world
