WHAT IT’S REALLY ABOUT
Big Five Beats Myers-Briggs, Plus Five Research-Backed Habit Hacks Revealed
- Spencer Greenberg discusses his new research comparing popular personality frameworks, finding the Big Five model predicts real-life outcomes roughly twice as well as Myers-Briggs and infinitely better than astrology, despite people liking Myers-Briggs descriptions more. He explains why dichotomizing traits (e.g., “ENTJ”) and flattering language make Myers-Briggs feel accurate but reduce its scientific usefulness, while Big Five and HEXACO arise from empirical clustering of trait adjectives. The conversation then shifts to two large habit-formation studies that tested 22 techniques, identifying five simple, high-impact methods (like habit reflection, mini-habits, and social support) that reliably improve habit success. Finally, Spencer outlines his personal philosophy “valuism” and multiple complementary definitions of wisdom, emphasizing aligning intrinsic values, beliefs, and actions while effectively shaping outcomes.
IDEAS WORTH REMEMBERING
5 ideasRely on Big Five over Myers-Briggs for real-life prediction.
Spencer’s study of 42 life outcomes found zodiac signs had zero predictive power, a Jungian/Myers-Briggs-style test correlated at about 0.11, and Big Five at about 0.22—roughly twice as accurate, even when you drop neuroticism. Use Myers-Briggs as shorthand language if you like, but treat Big Five as the serious tool.
Avoid dichotomizing personality traits; treat them as continuous.
Most traits follow a bell curve, so cutting at a midpoint (“you’re an introvert or extrovert”) lumps moderates with extremes and makes scores unstable—Spencer showed turning MBTI-style scores into hard types drops prediction from ~0.11 to ~0.08. Whenever possible, keep numeric trait scores instead of forcing types.
Choose habits you’re genuinely motivated to form.
Across Spencer’s large habit study, initial motivation was one of the strongest predictors of long-term success, more than most techniques. Instead of force-feeding yourself a habit you dread, start with one you truly care about to dramatically raise your odds of sticking with it.
Use the five validated habit techniques as a ‘stack.’
The best performers were: (1) habit reflection (analyze a past successful habit and apply lessons), (2) home reminders (notes or physical cues placed where you’ll see them), (3) mini-habits (a trivially small fallback version like 10 push-ups), (4) support of a friend (explicitly enlist someone to help), and (5) listing habit benefits (write and revisit why the habit matters). Combined in the “Daily Ritual” tool, this stack outperformed control over eight weeks.
Distinguish intrinsic from instrumental values to avoid chasing empty goals.
Intrinsic values are things you care about for their own sake (e.g., happiness, reducing suffering); instrumental values (e.g., money, status, tools) only matter because they help you get intrinsic goods. Many people accidentally treat instrumental values as ultimate ends, leading to unfulfilling life strategies.
