Book Summary: How We Decide (Jonah Lehrer)
How We Decide by Jonah Lehrer delves into the science of decision-making, exploring how the brain balances logic and emotion to reach conclusions. Lehrer explains how both rational and emotional processes affect our choices, with lessons drawn from neuroscience, psychology, and real-world examples. For product managers, understanding these insights provides practical strategies to improve decision-making, enhance user experiences, and design products that resonate with customers. Here’s a guide focused on applying Lehrer’s principles in product management.
The Dual-Process Theory: Emotion vs. Rationality
Lehrer explains that the brain uses two primary systems for decision-making: emotional (fast, instinctual) and rational (slow, analytical). Each has its strengths and weaknesses, and the key to good decision-making is knowing when to rely on one over the other.
Practical Tips for Product Managers:
Recognize When to Trust Instincts: For familiar, routine decisions (e.g., choosing a prioritization framework you’ve used successfully), rely on intuition as it saves time and effort. Trusting gut instincts based on past experience can be a powerful shortcut for quick choices.
Engage in Rational Analysis for Complex Issues: For high-stakes or unfamiliar decisions—like launching a new feature or targeting a new market—lean on thorough analysis. Break down data, weigh pros and cons, and consider potential consequences before deciding.
Balance Intuition with Data: When possible, use intuition as a starting point, then validate with data. If you feel that a certain feature will resonate with users, run A/B tests or conduct surveys to confirm your instincts.
The Role of Emotions in Decision-Making
Emotions play a crucial role in decision-making, often acting as a guide to what’s important. Lehrer emphasizes that emotions are not simply irrational impulses; they are valuable signals that reflect past experiences and learned associations.
Practical Tips for Product Managers:
Acknowledge Emotional Responses: If you’re feeling strongly about a decision, examine why. Emotions can reveal underlying values or biases. For example, if you feel anxious about a feature’s delay, it might indicate that timely releases are a core priority for you.
Understand User Emotions: Products that evoke positive emotions increase engagement and loyalty. Incorporate emotional design by using visuals, language, and experiences that resonate with users. For instance, simplify the onboarding process to reduce frustration or design congratulatory moments for task completion.
Use Emotional Feedback to Refine Products: Pay attention to how users feel when interacting with the product. Emotional feedback (like frustration with loading times or satisfaction with ease of use) can reveal valuable insights. Use tools like user interviews or sentiment analysis to gauge and respond to these feelings.
Leveraging the Power of Overthinking and Underthinking
Lehrer highlights the dangers of both overthinking (analyzing to the point of indecision) and underthinking (acting impulsively without sufficient thought). Good decision-makers know when to use each approach.
Practical Tips for Product Managers:
Set Boundaries for Analysis: For important decisions, allow a designated period for analysis to avoid overthinking. For example, limit research time to one week before making a call on whether to pursue a particular feature.
Create Decision Frameworks: Establish frameworks that speed up routine choices. Prioritization models like RICE (Reach, Impact, Confidence, Effort) or MoSCoW (Must have, Should have, Could have, Won’t have) can help you make fast, effective decisions without getting bogged down.
Allow Time for Reflection: If a decision doesn’t feel right, pause and revisit it later. Giving yourself time to let ideas “incubate” often leads to clearer insights and better choices.
Learning from Mistakes and Adjusting
Lehrer emphasizes the importance of learning from mistakes. Each mistake offers an opportunity to refine decision-making skills, as long as it’s analyzed constructively rather than ignored.
Practical Tips for Product Managers:
Conduct Post-Mortems: After a project or feature launch, review what went well and what didn’t. Document lessons learned to avoid similar issues in the future, creating a culture where mistakes are valued for their learning potential.
Encourage Open Feedback: Create an environment where team members feel comfortable discussing mistakes without fear of blame. Honest feedback can provide valuable perspectives that enhance future decision-making.
Iterate Based on Learnings: When a product feature doesn’t work as expected, don’t just move on—evaluate why. Did it fail due to a missed user need, poor implementation, or market timing? Use these insights to adjust your approach on the next iteration.
Recognizing Cognitive Biases
Lehrer details various cognitive biases, like confirmation bias (favoring information that supports pre-existing beliefs) and loss aversion (fearing losses more than valuing gains), which can cloud judgment. Recognizing these biases helps product managers make more balanced choices.
Practical Tips for Product Managers:
Challenge Assumptions: Before making decisions, actively seek out information that challenges your assumptions. For instance, if you believe a certain feature will be popular, test it with a diverse user group to uncover potential pitfalls.
Encourage Diverse Perspectives: Include team members from different departments and backgrounds in decision-making processes. Diverse viewpoints help offset personal biases and lead to more well-rounded choices.
Be Aware of Sunk Cost Fallacy: Avoid throwing good resources after bad just because of previous investments. For example, if a feature has consistently underperformed, consider pivoting rather than continuing to add resources in hopes of improvement.
Using Decision-Making Principles in Product Design
Applying the science of decision-making to product design itself can help users make more intuitive choices within the product, enhancing the user experience.
Practical Tips for Product Managers:
Simplify Decision Points: Design with minimalism in mind, reducing the number of options users have to choose from. Too many choices can lead to decision paralysis, so streamline where possible.
Guide Users with Defaults: When possible, set beneficial defaults (like recommended settings or popular options) to reduce cognitive load and help users make decisions quickly and confidently.
Offer “Undo” Options: People make mistakes; giving users the ability to easily correct or undo actions within the product makes them feel more secure and less hesitant in their decisions.
Conclusion
How We Decide offers valuable insights into the cognitive processes behind decision-making. For product managers, Lehrer’s principles provide guidance on balancing intuition and analysis, leveraging emotions, learning from mistakes, and countering cognitive biases. By applying these strategies to both team decision-making and product design, product managers can make better choices, build products that resonate with users, and create an environment where their teams feel empowered to think and act effectively.
