Personality tests put to the test: Myers-Briggs vs Big Five vs astrology
Spencer shares brand-new research comparing a Myers-Briggs-style “Jungian” test against the academic Big Five model, with zodiac signs as a control. They evaluate usefulness by how well each predicts 42 real-life outcomes (friends, life satisfaction, arrests, etc.).
- •Designing a Jungian-style test using public MBTI construct descriptions
- •Using 42 life facts/outcomes as an external benchmark for predictive power
- •Astrology included as a calibration/control condition
- •Results: astrology predicts nothing; Jungian predicts a little; Big Five about twice as predictive
- •Myers-Briggs-style approach lands “halfway between astrology and Big Five” in this setup
- 3:43 – 6:08
Why Myers-Briggs underperforms: factors, neuroticism, and the problem with dichotomies
They explore why the Big Five outpredicts the Jungian/MBTI-style approach. Spencer explains how removing neuroticism reduces Big Five accuracy but it still beats the Jungian test, and why converting traits into binary categories makes predictions worse.
- •Testing whether Big Five’s advantage is simply having five factors vs four
- •Dropping neuroticism reduces Big Five accuracy but doesn’t eliminate the gap
- •Bell-curve traits lose information when forced into binary buckets (I/E, N/S, etc.)
- •Binary “type” reporting increases instability for people near the midpoint
- •Predictive correlation drops further when results are dichotomized
- 6:08 – 12:38
Why people still love MBTI: better language, better feelings, worse branding for Big Five
Even though the Big Five predicts outcomes better, people perceive both reports as similarly accurate and feel better after the Jungian report. Spencer and Chris discuss how MBTI avoids negative-sounding labels and provides easy shorthand that Big Five struggles to match.
- •Participants rate Jungian and Big Five reports as similarly accurate subjectively
- •Jungian/MBTI reports tend to make people feel better than Big Five reports
- •Big Five trait names can feel insulting (e.g., “disagreeable,” “neurotic,” “closed”)
- •MBTI offers concise social shorthand (e.g., “ENTJ”)
- •Trade-off: accuracy (Big Five) vs communicability/branding (MBTI)
- 12:38 – 14:29
Building habits with evidence: a 22-technique randomized study and what actually matters
Spencer describes a large experiment testing 22 habit interventions at once by randomizing participants to receive five techniques each. Most interventions failed; motivation at the start strongly predicted success, emphasizing the difficulty of behavior change.
- •Testing 22 habit techniques simultaneously via randomized assignment
- •Most habit ‘hacks’ showed no measurable benefit in the pilot
- •Motivation level at the start is among the strongest predictors of success
- •Implication: choose habits you actually feel driven to do
- •Sets up the five techniques that showed the most promise
- 14:29 – 16:16
Habit technique #1: Habit reflection (learning from past successes)
The first effective technique is an introspective, self-customizing method: analyze a habit you previously succeeded at and extract actionable lessons for the new habit. Writing it down is emphasized as a key component.
- •Look back at a habit you already formed successfully
- •Write down what specifically helped you succeed (timing, accountability, environment, etc.)
- •Write down how to apply those lessons to the new habit
- •Self-customizing: uses your personal history as data
- •Parallels ‘outside view’ thinking to counter planning fallacy
- 16:16 – 18:07
Habit technique #2: Home reminders and the power of triggers (HABIT acronym)
They discuss triggers as central to habit formation using the HABIT framework (Humans, Activity, Bearing, Internal state, Time). Spencer’s surprisingly effective intervention is extremely simple: place visible notes/reminders around your home to cue the behavior.
- •Triggers framework: Humans, Activity, Bearing/location, Internal state, Time
- •Designing a ‘dead easy’ trigger-based intervention anyone can implement
- •Home reminders: notes placed around the environment to prompt action
- •Why it works: constant cues reduce forgetting and friction
- •Chris’ eye-drop example as a physical, distributed reminder system
- 18:07 – 22:31
Habit technique #3: Mini habits to prevent ‘zero days’ and protect identity
Mini habits create a tiny, non-negotiable version of a behavior to keep consistency even when motivation is low. They explore why this prevents total dropout, creates a graded success metric, and supports identity-based habit change.
- •Define a tiny version of the habit that is nearly impossible to skip
- •Rule: if you can’t do the full habit, you must do the mini habit
- •Main failure mode is doing nothing, not doing ‘too little’
- •Graded success reduces shame spirals and all-or-nothing thinking
- •Helpful for periods of depression/anxiety where small wins matter
- 22:31 – 27:10
Habit techniques #4–#5: Social support and listing benefits + stacking into a validated tool
Two more winners: enlist a supportive person and explicitly list the habit’s benefits to boost motivation. Spencer explains how they packaged the five techniques into a free ‘Daily Ritual’ tool and confirmed benefits in an 8-week randomized trial.
- •Support of a friend: recruit someone and specify how they can help
- •Listing habit benefits: write reasons/upsides and revisit to refresh motivation
- •Question of worst techniques; WOOP surprisingly shows no effect in their study
- •Second study: stack the five interventions into the ‘Daily Ritual’ tool
- •RCT over eight weeks shows higher adherence vs control group
- 27:10 – 30:46
Valueism (valuousm): intrinsic vs instrumental values as a life philosophy
Spencer introduces valueism, his personal philosophy centered on identifying what you intrinsically value and then using effective methods to create it. He distinguishes intrinsic values (ends) from instrumental values (means) and argues people often confuse them.
- •Intrinsic values: valued for their own sake (e.g., happiness)
- •Instrumental values: valuable as a means (e.g., money on a deserted island)
- •Common trap: pursuing instrumental values as if they were ultimate goals
- •Valueism’s two steps: clarify intrinsic values, then act effectively to create them
- •Framed as guidance for people without an overarching belief system
- 30:46 – 34:20
Clarifying intrinsic values in practice: common pitfalls and resolving value conflicts
Spencer describes challenges in identifying true intrinsic values and how their tool teaches people to separate them from instrumental ones. He then explains how to navigate conflicts between intrinsic values by restating decisions as value trade-offs and accepting subjectivity in weighting them.
- •People frequently list instrumental items as ‘intrinsic’ without training
- •ClearerThinking intrinsic values test includes a training module
- •Intrinsic values can conflict (e.g., honesty vs not hurting a friend)
- •Technique: restate dilemmas explicitly as a trade-off between values
- •Some decisions have no objective answer; outcome depends on personal weighting
- 34:20 – 45:55
Do we choose our values? Sources of values, stability over time, and living others’ values
They examine where values come from—evolutionary predispositions, experience, and culture—and how stable they tend to be in adulthood. Spencer shares an anecdote about someone pursuing a partner aligned with parental values rather than her own, highlighting how people can unknowingly live for others’ values.
- •Values partly shaped by evolution/capacities, then by life experience and culture
- •Values are relatively stable in mid-20s to 30s but can shift after major events
- •Generally: changing values isn’t the goal unless a meta-value calls for it
- •Anecdote: boyfriend fits parents’ values, not hers—causing dissatisfaction
- •Hard part of valueism: noticing where your life diverges from your stated values
- 45:55 – 57:00
Intuition in decision-making: the FIRE framework and integrating gut + analysis
Spencer proposes the FIRE framework for when intuition is trustworthy and when analysis should lead. They discuss how to incorporate intuition as information without letting it fully dictate choices, using thought experiments to uncover what your ‘black box’ intuition is reacting to.
- •FIRE: Fast decisions, Irrelevant decisions, Repetitious decisions, Evolutionary decisions
- •Intuition improves with repetition and clear feedback (archery analogy; chess expertise)
- •Dangers of misapplied pattern-matching in new domains
- •Integration strategy: don’t ignore intuition—use it as a signal, then investigate it
- •Trauma can make intuition ‘noisy,’ leading people to overcorrect and distrust it entirely
- 57:00 – 1:06:56
What wisdom is and why it matters: six definitions from alignment to perspective
Chris and Spencer unpack why wisdom is hard to define yet deeply important, then walk through multiple definitions. Spencer outlines wisdom as self-consistency and causal control, and explores the idea that wisdom combines knowledge with goodness, before discussing traditional virtue-based wisdom and broader ‘wisdom as search’ and ‘wisdom as perspective’.
- •Chris’ view: wisdom connects intention, action, and outcomes, plus meta-intention
- •Wisdom as self-consistency: alignment of values, beliefs, and actions
- •Wisdom as causal control: navigating complexity to produce beneficial outcomes on average
- •Wisdom as knowledge × goodness: product (not sum) implies both are required
- •Additional lenses: wisdom as virtue, as lifelong search, and as multi-perspective integration
- 1:06:56 – 1:22:03
Goodness, evil, and modern moral confusion + closing and where to find Spencer
They probe whether goodness must be part of wisdom and discuss how ‘evil’ often stems from harmful false beliefs (philosophical disorder) more than a desire to harm. They touch on media depictions of evil and attractiveness bias, then close with Spencer’s resources and where listeners can follow his work.
- •Goodness may arise from shared human values rather than objective moral facts
- •‘Philosophical disorder’: false, harmful beliefs driving destructive actions (e.g., cults)
- •Most ‘evil’ isn’t from people intrinsically valuing harm; more often indifference or mistaken righteousness
- •Fiction often simplifies villains into harm-valuing caricatures; real life is messier
