Think Better with Shige Oishi

What is a good life? Is it about feeling happy yourself? Or helping others even if it comes at the expense of your own happiness?

On January 14, 2026, Shige Oishi (University of Chicago) joined the Think Better Speaker Series to discuss “What is a Good Life? A Psychological Perspective.” He examined how happiness, meaning, and psychological richness guide our choices and contribute to a fulfilling life.

What is a Good Life?

Shige Oishi is a social and personality psychologist whose work spans wellbeing, cross-cultural differences, residential mobility, gratitude, and more. In this Think Better talk, he drew on decades of research and his recent book Life in Three Dimensions to revisit a very old question: What is a good life?

Historically, both philosophy and psychology have tried to answer that question in a single dimension. First happiness, then meaning. Oishi argued that these are crucial but incomplete. To really understand and experience a good life, we need a third dimension: psychological richness, which is defined as having a life full of interesting, varied, and perspective-changing experiences. He then showed how these three dimensions can complement each other, and why a fuller life means learning to balance all three over time.

Happiness: Frequency, Not Fireworks

Western history, beginning with Aristotle, has long put happiness at the center of the good life. Aristotle taught that various goals such as money or health are only means to an end and that true happiness comes from living well. Modern psychology updated this idea in the 1980s when researchers like Oishi’s advisor Ed Diener began to measure “subjective wellbeing,” asking people directly about their life satisfaction.

Diener’s approach changed the way psychologists think about happiness, shifting the focus from philosophical ideals to real experiences and self-assessment.

What the Science Shows About Happiness

  • Happiness is only loosely linked to external achievements. Wealthier people are only slightly happier than average college students, and lottery winners see their happiness spike only temporarily.
  • Physical attractiveness matters only to the extent people believe they are attractive, not how others rate them.
  • Personality factors weigh heavily. A grateful outlook and low neuroticism are linked to greater happiness.
  • Ambition can actually reduce happiness. Maximizers (those who strive for the best) may get higher rewards but often end up less satisfied than satisficers (those content with “good enough”).
  • Frequent small pleasures matter more than rare big thrills. People who enjoy regular moments with friends or family tend to be happier than those who focus on occasional big events.

While happiness is a common aspiration, Oishi addressed critiques from figures like Gustave Flaubert, who saw happiness as potentially shallow or selfish if pursued without meaning or purpose.

Meaning: Seeking Purpose Beyond the Self

Many people believe that happiness alone does not capture a truly fulfilling life; they seek meaning as well. The scientific study of meaning is relatively recent and complex. Oishi credited his graduate student, Mike Steger, with developing key measures for meaning in life, such as the Meaning in Life Questionnaire.

Research shows that a meaningful life has three main elements:

  • Significance: Feeling your life matters, especially to those you care for or support.
  • Purpose: Having clear goals and a sense of direction.
  • Coherence: Building a life story where experiences fit together logically.

Sources of meaning often center on family and career. However, these may change over time: Children grow up, careers end, and adults sometimes struggle to find significance. Tolstoy famously experienced this existential crisis, questioning the meaning of his achievements despite universal acclaim.

Oishi likened the search for meaning to interpreting abstract art. Meaning depends on connecting the dots between past, present, and future. He also noted that nostalgic people who keep long-term relationships are more likely to see their lives as one clear, connected story.

Building meaning may involve mentoring, planting metaphorical trees that symbolize legacy, or finding ways to see life as part of something lasting.

Psychological Richness: A Third Dimension of the Good Life

Even after decades studying happiness and meaning, Oishi felt something was missing. He introduced the concept of “psychological richness,” describing a life full of diverse, novel, and interesting experiences.

Psychological richness is not about comfort or virtue. It is about enriching your mental portfolio through curiosity, exploration, and a willingness to try new things, even those that bring discomfort.

How to be Rich, Psychologically

  • People who score high in openness to experience tend to lead psychologically rich lives. This trait is not strongly associated with happiness or meaning.
  • Richness grows through novelty, adventure, and breaking daily routines.
  • This richness adds depth to your life, creating a mental portfolio of unique and interesting memories and diverse experiences that shape a distinctive and engaging personal story.

Research from Oishi’s lab found that students who studied abroad or took challenging courses increased their psychological richness, even if their happiness or sense of meaning did not change. Engaging in new activities day to day was linked to psychological richness, whereas routine days boosted happiness but not richness.

Society and the Challenge of Specialization

Oishi discussed how efficiency measures like division of labor boost productivity but limit personal richness. Specialization often makes life less interesting. Instead, he encouraged embracing “do-it-yourself” projects and experiences, even if they are inefficient or difficult, because they bring memorable stories and enrich your life.

His example of building a patio with his family illustrated that the process, with all its challenges, led to a rewarding and psychologically rich experience.

Finding Balance: Audience Questions

During the Q&A, participants raised thoughtful questions about practical issues:

  • Intrinsic versus extrinsic motivation: Doing things for external approval or social validation may still lead to growth, but the most meaningful experiences come when individuals reflect and learn from what they do.
  • Balancing happiness and richness: While small daily joys support happiness, occasional adventures or trying something new builds psychological richness. Even minor changes like altering your walking route or revisiting a favorite book can add richness to your life.
  • Cultural and life stage differences: Oishi’s international research shows that preferences for happiness, meaning, or richness vary across countries and ages.

Conclusion: Living a Good Life in Three Dimensions

Oishi concluded with a quote from Eleanor Roosevelt: “the purpose of life after all is to live it, to taste experience to the utmost, to reach out eagerly and without fear for newer and richer experiences.” A good life is not one dimensional but instead has three core elements that we can actively cultivate.

Oishi argued that we should:

  • Cultivate happiness by being a “satisficer,” practicing gratitude, and building a life full of frequent, small, repeatable joys.
  • Pursue meaning by being useful to others, leaving a legacy, and connecting the dots between our past, present, and future so that life feels coherent and significant.
  • Enrich our lives psychologically by doing something new, changing routines, staying curious, being playful, and remaining open to experiences that challenge and change us.

For Oishi, a good life does not mean choosing only one of these paths. It means learning to integrate all three: happiness, meaning, and psychological richness, and adjusting the balance as circumstances and life stages change. He encourages us to keep asking, throughout life, not just whether we are happy or whether our lives are meaningful, but also whether our lives are psychologically rich, and to seek out opportunities for joy, significance, and memorable, mind-expanding experiences.
