Research on personality frameworks, AI behavior analysis, attachment theory, and practical self-knowledge — written for curious people, not academics.
You got INFP in 2019, INFJ last year, and INTJ this morning. Here's why — and what actually makes a personality reading reliable.
The way you prompt an AI — how much context you give, whether you use lists or prose, how you handle follow-ups — carries a consistent personality signal. Here's what researchers have found.
Secure attachment is the most researched predictor of relationship satisfaction. Here's what it actually looks like — and what you can do if you didn't start there.
Personality tests tell you what you scored. Personality intelligence tells you what your scores mean for how you actually operate — and it starts with better data.
The HEXACO model adds a sixth dimension to the Big Five that predicts something the original framework consistently misses — how people behave when no one is watching.
Researchers analyzed 62,000 ChatGPT conversations and found they could predict personality traits with significantly better-than-chance accuracy. Here's what they found — and what it means.
Schwartz values theory was validated across 80 countries and predicts real decision-making better than almost any other personality framework. Most people have never heard of it.
AI companies are quietly building personality models of their users. Most people don't know this is happening, and most products built on it are not designed with the user's interests in mind.
Every major personality test asks you to describe yourself. The research on self-report accuracy isn't encouraging. Here's what behavioral data offers instead — and why it changes what's possible.
Most people's self-perception diverges from their actual personality in consistent, predictable ways. Understanding the gap is more useful than closing it.
Dating apps have spent billions trying to predict romantic compatibility. Nobody has applied the same rigor to friendship. Here's what the research shows — and why the patterns are different from what you'd expect.
After years of getting different MBTI types, I tried something different — uploading my actual conversation history. The reading was harder to dismiss.
The research on MBTI compatibility is not promising. The research on what actually predicts relationship success is much more interesting.
A step-by-step guide to downloading your Google Gemini conversation data — and how to turn it into a personality reading.
A step-by-step guide to downloading your Claude.ai conversation data — and the most useful thing you can do with it once you have it.
A step-by-step guide to downloading your ChatGPT conversation data — and what you can actually do with it once you have it.
Not all personality tests are equal. The research on accuracy varies widely depending on the framework, the measurement method, and what outcome you're trying to predict.
The Big Five is the most validated personality model in psychology. HEXACO extends it with a sixth dimension that predicts something the Big Five consistently misses. Here's what each measures — and when each matters.
Most people hear "Dark Triad" and picture a cartoon villain. The research tells a more complicated — and more useful — story.
One of these frameworks is the foundation of modern personality psychology. The other changes your type when you're in a bad mood. Here's what the research actually shows.
Personality predicts career outcomes more reliably than most HR departments acknowledge. Here's what the research actually shows — and how to use it.
If you've taken 16Personalities, Truity, and Crystal and keep getting different answers, the problem isn't you — it's the measurement method. Here's what actually works.
Attachment style and personality type measure different things. In relationship contexts, one predicts outcomes far more reliably than the other.
The way you interact with AI tools carries attachment signals. Anxious users seek reassurance differently than avoidant ones. Secure users engage differently still. Here's what the patterns show.
Anxious attachment isn't a character flaw. It's a strategy your nervous system learned early on — and understanding it is the first step to changing how it operates.
The questions you ask an AI say more about your personality than any survey ever could. Here's what your conversation history is quietly measuring.
