Episode: How to Change Your Personality
Air Date: September 29, 2025
Episode Overview
This episode of Unexplainable dives into the scientific mysteries behind personality change, featuring a crossover interview from Vox’s The Gray Area hosted by John Iley. The guest, Olga Hazan – staff writer at The Atlantic and author of "Me, But Better: The Science and Promise of Personality Change" – discusses her year-long quest to actively change aspects of her own personality, blending personal anecdotes with the latest research on the Big Five traits, the psychology of self-improvement, and the realistic limits of transformation.
Key Discussion Points & Insights
1. Defining Personality
- Personality: Defined by Hazan as “the consistent thoughts and behaviors that you have every day” (04:05).
- Personality traits are tendencies; while we may ‘perform’ different traits situationally, most people have underlying patterns that are relatively stable (04:52).
- Big Five Model: The episode centers on the Big Five: neuroticism, extraversion, agreeableness, openness to experience, and conscientiousness (06:11).
2. The Performance vs. Core Nature of Personality
- Hazan explains how people often “perform” traits (e.g., acting extroverted in a job interview despite being an introvert), yet fall back to their natural patterns unless intentionally trying to change (04:52–06:11).
3. Why Change?
- Hazan sought to adjust her “high neuroticism” and deepen social connections, emphasizing that self-love and self-improvement can coexist (07:39).
- Catalyzing moment: a series of minor frustrations (bad haircut, traffic) led to a meltdown, highlighting how her reactions undermined her ability to enjoy life (08:05).
4. The Nature of Neuroticism & Catastrophizing
- Catastrophizing—seeing threats everywhere—is a signature pattern of neuroticism, often leading to chronic anxiety and dissatisfaction (09:55).
- Quote: “The reason you’re catastrophizing is not because … you’re silly or … not realistic, but because you kind of can see the threats coming from every direction” – Hazan (09:55).
5. Agreeableness and Boundaries
- Too much agreeableness can lead to people-pleasing and poor boundaries; personal growth can involve learning to say no as much as it involves increasing warmth and empathy (12:52).
6. Challenges in Changing Traits
- Hazan found neuroticism the hardest to change; meditation and mindfulness help, but can feel unnatural or even threatening to those who see anxiety as motivational (13:56–14:44).
- “I think that like anxiety is protective, at least for me. Like it … is like the fire under me.” – Hazan (14:44)
7. Does Personality Change With Age or Effort?
- Personality is not “set like plaster” at 30—research shows that people change naturally over time, often becoming less neurotic and open as they age (23:03).
- Intentional change: interventions can prompt personality shifts beyond natural drift (23:03–24:20).
8. Limits and Possibilities of Change
- Genetic baseline is real, but “tinkering at the margins” can lead to significant improvements—a la Dan Harris’s “10% Happier” (26:04–26:06).
- Behavioral traits (e.g., conscientiousness) are easiest to change by acting the part—“fake it till you make it” (28:41–28:55).
9. Interventions for Change
- Extroversion: Signing up for structured social activities (e.g., improv) provides accountability and effectively pushes comfort zones (29:54–30:08).
- Conscientiousness: Start by decluttering before creating new organizational systems (36:55).
- Neuroticism: Meditation and mindfulness courses, even when difficult, proved helpful in reducing depression and anxiety (15:14–16:58).
- “The class that I took … had a lot of Buddhist teachings … that was, weirdly, very helpful to me.” – Hazan (15:24)
- The ACT acronym: Accept your negative feelings, Commit to your values, Take action—a useful, practical approach for long-term change (37:49–38:35).
10. Knowing When to Stop Trying to Change
- Persistence is good, but knowing when a change isn’t authentic or valuable is crucial. Hazan quit running a foreign film meetup when it brought no joy, contrasting with the positive discomfort of improv (33:29–34:35).
11. Value of Negative Traits
- Some degree of neuroticism or anxiety can be adaptive—e.g., motivating careful parenting or driving preparation (35:06).
12. Agency, Belief, and the Motivation to Change
- Belief in your own capacity to change is a “fundamental precondition.” If you don’t believe change is possible, you’re unlikely to try (39:13–39:28).

Practical Takeaways
- Action precedes identity: Acting in new ways (joining improv, decluttering) can drive internal change.
- Accountability matters: Structured, time-bound commitments outperform vague intentions for behavioral shifts.
- Mindfulness helps, but isn’t a cure-all: Particularly valuable for reducing reactivity, but may feel unnatural to high-anxiety individuals.
- Aim for progress, not perfection: Small “margin” changes can drastically improve well-being.
- Both acceptance and effort: Self-acceptance and improvement are not mutually exclusive.
- Belief and openness are prerequisites: You must believe change is possible to initiate it.
Episode Tone
The conversation is candid, self-reflective, and gently humorous—with Hazan’s vulnerability and honesty contrasting with John Iley’s self-deprecating remarks about his own neuroticism. The tone is neither dryly scientific nor oversold with self-help enthusiasm, instead keeping the focus on evidence-based optimism and realism about what can—and can’t—be changed.
