TL;DR
The talk is about learning how to anticipate and prevent problems before they happen using a concept called the pre-mortem. The talk involves personal anecdotes and scientific insights on stress and its effects on making rational decisions, especially in critical situations like medical choices. The speaker encourages cultivating awareness of potential failures and establishing systems to mitigate or avoid those failures.
“And it wasn’t until I got to the airport check-in counter, that I realized I didn’t have my passport.”

TALK SUMMARY
In his TED Talk, the neuroscientist recounts a personal experience where stress caused him to forget his passport, leading to travel troubles. This incident exemplifies how stress can impair our thinking, as the brain releases cortisol that clouds our judgment. He discusses the importance of a proactive strategy-a pre-mortem, suggested by Noble Prize-winner Daniel Kahneman-that helps identify potential problems before they occur and how to prevent them. He provides practical advice for home and travel preparation to minimize the effects of stress. Specifically, he discusses informed medical decisions, citing the ‘number needed to treat’ (NNT) statistic and its importance for understanding the effectiveness of a medical intervention.
“Cortisol is toxic, and it causes cloudy thinking. So part of the practice of the pre-mortem is to recognize that under stress you’re not going to be at your best, and you should put systems in place.”
Daniel Levitin
KEY MESSAGE
The key message is that by using a technique called the pre-mortem, we can foresee and potentially avoid mistakes and failures. We should prepare ourselves mentally for stressful situations and make informed decisions in advance to better manage the challenges we may face in life.
“Prospective hindsight, or pre-mortem, is looking ahead and trying to figure out all the things that could go wrong and then trying to figure out what you can do to prevent those things from happening, or to minimize the damage.”

INNOVATIVE CONCEPTS
- Pre-mortem: A technique to anticipate and prevent mistakes by envisioning potential failures and implementing systems to avoid them.
- Designated Places: Using the brain’s spatial memory strengths by assigning specific spots for frequently lost items to prevent misplacement.
- Number Needed to Treat (NNT): A statistical measure used to determine how many people need to undergo a treatment before one person benefits, highlighting the importance of informed medical decisions.
- Cortisol’s Effects: Understanding the impact of stress hormone cortisol on decision-making and how it impairs rational thinking.
- Photo Documentation: The practice of taking photos of important documents and storing them in the cloud for easy access in case of emergencies.
“There’s a structure in the brain called the hippocampus, that evolved over tens of thousands of years, to keep track of the locations of important things.”
Daniel Levitin
IDEAS:
- The brain’s hippocampus is critical for spatial memory and helps us remember the locations of items, which is why it’s essential to have dedicated spots for important things like keys and passports to prevent loss.
- Under stress, the brain’s decision-making capabilities are significantly diminished due to cortisol, which underscores the necessity of established systems and precautionary measures.
- A proactive approach to problem-solving, like the pre-mortem technique, is not only beneficial in everyday life scenarios but critical in making informed medical decisions.
- Keeping digital copies of important documents such as credit cards and passports in the cloud can be a lifesaver during travel or emergencies.
- Understanding the Number Needed to Treat statistic is crucial for making more informed choices about medical treatments and recognizing their potential risks and benefits.
- Stress can lead to clouded judgment, making it important to create routines and systems to counteract this effect when making important decisions.
- Creating a systematic approach to prevent misfortunes, for instance through designated places for items, contributes to organization and stress reduction.
- Being informed about the possible adverse effects and efficacy rates of medical procedures can empower individuals to make choices that align with their values and preferences.
- The talk suggests a gradual process of becoming more organized by identifying weaknesses in one’s habits and striving to improve them.
- Recognizing that failures are an inherent part of being human can help create a culture of preparation and prevention rather than one of blame when things go wrong.
FACTS:
- At minus 40 degrees, the Celsius and Fahrenheit scales converge, which indicates extremely cold temperatures where the speaker’s initial anecdote is set.
- The brain structure responsible for tracking the locations of important objects through spatial memory is called the hippocampus.
- Cortisol’s impact on the brain during stressful situations hampers our ability to think clearly, affecting decision-making processes.
- The Number Needed to Treat (NNT) for the most widely prescribed statin is 300, meaning 300 people need to take it for one to benefit, highlighting the importance of informed medical decisions.
- Medical decisions are often made under stress, which can lead to clouded judgment, stressing the necessity for a pre-mortem approach to decision-making.
“You might change your mind in the heat of the moment, but at least you’re practiced with this kind of thinking.”

EMOTIONAL ESSENCE
The emotional essence of the talk is both reflective and instructional. The speaker’s personal anecdotes evoke empathy and humor, engaging the audience. His discussion on the importance of proactive decision-making, especially in stressful situations, inspires people to think more carefully about their choices and how they prepare for the unexpected.
