✅ Toby's Top Takeaway From The Intelligence Trap by David Robson


Telling Smart People, They Are Stupid



This never goes down well. Yet we all know many intelligent people who can often be so damn stupid. This phenomenon, known as the “intelligence trap,” is explored in David Robson's The Intelligence Trap.


The book reveals that intelligence doesn’t always equate to wise decision-making. Sometimes, the very qualities that make someone intellectually brilliant can lead them into cognitive pitfalls.


Intelligent people are often overconfident in their abilities, making them less open to feedback. The more competent someone is, the more likely they believe they have all the answers. This is what Robson calls earned dogmatism—the idea that expertise leads to a sense of intellectual entitlement, resulting in rigid thinking.


The problem is, how do you convince an intelligent person they are stupid?


Tell it straight, and you'll likely get the door slammed in your face. Even worse, it may trigger the backfire effect. A cognitive bias results in beliefs being strengthened, not weakened. Even providing factual data doesn't work. Intelligent people are excellent at defending their beliefs, even when wrong, and this is known as motivated reasoning.


I've found there are three ways:


  • Connect Before You Correct—Listen and ask questions before challenging the person. They are much more likely to respond well if you have built rapport.

  • Be Kind—People are generally much more rational in their arguments and more willing to admit the limits of their knowledge and understanding if treated with respect and compassion. Aggression, by contrast, leads them to feel that their identity is threatened, which can make them closed-minded.

  • Challenge the Task, not the Person - The person is not stupid; their decision might be. Rather than critiquing the character traits, challenge the task at hand.


Remember these tips the next time you face a smart, stupid person.

 

💡 3 Big Ideas From The Intelligence Trap by David Robson


  1. Intelligence Doesn’t Equal Wisdom - High intelligence can help you solve complex problems quickly, but it can lead to overconfidence and poor judgment without the proper mental checks and balances. Robson uses the metaphor of a fast car without proper controls—intelligence is the engine, but wisdom is the steering wheel, brakes, and map. Leaders must cultivate intellectual humility and self-awareness to avoid making critical errors despite their intelligence​.

  2. The Dangers of Motivated Reasoning - Intelligent people are often more skilled at justifying their beliefs than objectively analysing them. This concept, called ‘motivated reasoning,’ shows how smart individuals can use their cognitive abilities to defend flawed decisions or biased viewpoints. For leaders, it’s crucial to encourage a culture where assumptions are questioned and feedback is welcomed, ensuring that decisions are made based on evidence rather than ego​.

  3. Collective Intelligence Trumps Individual Brilliance - Social sensitivity and intellectual humility often lead to better outcomes than pure IQ in team settings. Research demonstrates that diverse teams where all members contribute equally perform better than teams dominated by a few high-powered individuals. For leaders, this means fostering inclusive environments where every voice is heard and collaboration is prioritised over hierarchy​.
