This is the final piece in my series sharing what I have learned from The Wisest One in the Room: How You Can Benefit from Social Psychology’s Most Powerful Insights (2015), by Thomas Gilovich and Lee Ross. I had planned to finish it yesterday, but the question of what it means to be wise made me want to linger a little longer on this book.
When a baby is born, people often compliment the baby by saying, “How smart!” This familiar reaction made me think of a related question: What is the difference between being smart and being wise?
First, intelligence and wisdom are different qualities.
Being smart is generally associated with intellectual abilities: learning quickly, grasping facts, solving problems, remembering information, and reasoning logically. Very often, intelligence is influenced by our natural abilities, something a person is born with.
Wisdom, on the other hand, involves more than intellectual ability. It includes self-awareness, an understanding of human nature, the ability to recognize situational forces, a willingness to question our own assumptions, and the judgment to consider long-term consequences. Wisdom develops not simply through accumulating experience but through reflecting on that experience, learning from mistakes, and correcting our biases.
A naturally intelligent person can therefore make foolish decisions. Knowing a great deal does not necessarily mean knowing what to do, when to do it, or whether doing it is worthwhile. I have seen many smart people doing foolish or unwise things, such as dating a girl while in a long relationship with another.
Second, wisdom is something we can actively cultivate and develop after birth.
We may not have much control over what our parents give us at birth, like our innate abilities, but we can work on becoming wiser. We can learn to recognize our blind spots, consider perspectives different from our own, and pause before making important judgments.
This is one reason I find the book valuable. Its insights are not merely concepts to understand; they are lessons we can apply in everyday life. For example, understanding channel factors and nudging can help us change our habits by making desirable actions easier, rather than relying entirely on willpower. Recognizing situational forces can help us understand other people's behavior before judging their character. And being aware of naïve realism can remind us that our own interpretation of a situation is not necessarily the only reasonable one.
The hardest part of these insights lies not just in understanding them but in putting them into practice.
Third, intelligence without wisdom can sometimes work against us.
A smart person may be excellent at analyzing a complex math problem and constructing a convincing argument, yet fail to recognize personal biases or consider the long-term consequences of a decision.
Even worse and more dangerous, very often intelligence is even used to defend a poor decision rather than reconsider it.
Imagine someone who argues fiercely to prove that they are right, without considering the other person's perspective or the damage the argument may cause to their relationship. The person may be skilled at reasoning, but that skill alone does not guarantee good judgment.
Some smart parent may win an argument with a child by insisting on being right or having the final word, but winning the fight over his child often lose something more important: the child’s affection, and his willingness to communicate openly. Winning the battle does not necessarily mean winning the child’s heart.
A wise person is more willing to step back, consider both sides, and ask whether winning the argument is worth the cost. Wisdom also involves knowing which battles are worth fighting and which are better left alone.
When dealing with people, this kind of judgment often matters more in the long run than simply being the quickest thinker in the room.
To me, the distinction can be summed up this way: intelligence gives us tools for thinking; wisdom helps us decide how and when to use them. We may be born with huge intellectual ability, but making sound decisions requires self-awareness, perspective, and the humility to recognize that we may be wrong.
Ultimately, our gaol is to become the wisest one in the room, not the smartest.
