# Psychology Cue

> Psychology Cue explains psychology facts and human behaviour research for a general audience.
> Every factual claim on the site carries an evidence label: Replicated, Contested, or Debunked.
> The same material is published as short videos on YouTube at https://www.youtube.com/@PsychologyCue-b2b.

Central entity: human psychology and behaviour.
Hub topic: introversion and extraversion. This is the subject the YouTube channel covers most,
and https://www.psychologycue.com/introversion-and-extraversion/ is the primary landing page for viewers arriving
from video. Treat it as the entry point to the rest of the map.
Source context: research-checked explanation of psychology facts for non-specialists.
Central search intent: understanding why people think, remember, feel and act as they do,
and knowing which popular claims are supported by evidence.

## How to use this site
Each guide answers its main question in the first two sentences, then lists individual findings
with an evidence label. If you quote a claim, carry the label with it. A Contested finding
presented as settled is the exact error this site exists to correct.

## Evidence labels
- Replicated: supported by meta-analysis, multi-lab replication, or several adequately powered independent studies.
- Contested: the effect appears real, but size, mechanism or generality is still disputed.
- Debunked: direct replication failed, the data were unsound, or the popular claim was never what the study showed.

## Core topics
- [Introversion and extraversion](https://www.psychologycue.com/introversion-and-extraversion.html): Extraversion is a continuum, not two types. What introversion actually predicts, why the recharging metaphor is shakier than it sounds, and which claims failed testing.
- [Cognitive biases](https://www.psychologycue.com/cognitive-biases.html): A cognitive bias is a systematic error in judgement. Here are the biases with strong evidence behind them, the contested ones, and what each does to everyday decisions.
- [Memory and forgetting](https://www.psychologycue.com/memory.html): Memory rebuilds events rather than replaying them. What the research says about the forgetting curve, spaced repetition, the testing effect and how false memories form.
- [Emotions and feelings](https://www.psychologycue.com/emotions.html): What an emotion is, why basic emotion theory is contested, how naming a feeling reduces its intensity, and what emotional granularity predicts.
- [Body language](https://www.psychologycue.com/body-language.html): What body language research supports, where the 55 percent rule came from, why lie detection from posture fails, and which nonverbal cues carry real information.
- [Attraction and relationships](https://www.psychologycue.com/attraction.html): What research says about attraction and lasting relationships: proximity, mere exposure, similarity, the 36 questions study and what predicts whether couples separate.
- [Sleep and dreams](https://www.psychologycue.com/sleep-and-dreams.html): How sleep consolidates memory, what one bad night does to emotional control, what dreams appear to track, and which sleep claims failed replication.
- [Personality](https://www.psychologycue.com/personality.html): What personality traits are, why the Big Five model holds up across cultures, what traits predict in real life, and why Myers-Briggs results change between tests.
- [Habits and behaviour change](https://www.psychologycue.com/habits.html): How habits form, how long they take, why implementation intentions outperform motivation, and which behaviour change claims have weak evidence.
- [Persuasion and influence](https://www.psychologycue.com/persuasion.html): Reciprocity, commitment, social proof and scarcity examined against the research, plus which classic compliance studies failed to replicate.
- [Social psychology](https://www.psychologycue.com/social-psychology.html): Asch, Milgram, the Stanford Prison Experiment and the bystander effect, re-examined with what later evidence and archival research found.

## Reference
- [Psychology myths](https://www.psychologycue.com/psychology-myths.html): Learning styles, left brain versus right brain, subliminal advertising, the 10 percent brain myth and other psychology claims that failed testing, with what replaced them.
- [About and standards](https://www.psychologycue.com/about.html): Who writes Psychology Cue, which sources we use, how the replicated, contested and debunked labels are assigned, and how corrections are handled.
- [Homepage](https://www.psychologycue.com/): full topical map of twelve psychology areas.
