Psychology facts, graded by evidence
Most psychology facts online are half remembered. These are checked.
Psychology Cue explains how people think, remember, feel and behave, using the published research rather than the version that spread through social media. Every claim on this site carries a label telling you whether it has replicated, whether researchers still argue about it, or whether it fell apart under scrutiny.
What this site is for
A lot of popular psychology is downstream of one study from the 1970s that nobody re-read. Power poses, learning styles, the 55 percent body language rule: all of them travelled further than the evidence did. Since 2011, psychologists have been running large replication projects and finding that a meaningful share of famous results do not hold. That work rarely reaches the people who quote the original claims.
So the job here is narrow. Take a psychology question people actually ask, find what the research says now, and write it down in plain English with the uncertainty left in. When a finding is solid, we say so. When the effect shrank after replication, we say that too, because the shrinking is usually the interesting part.
The topical map
Thirteen areas, each one a full guide with its own sub-pages, cross-linked where the ideas actually connect. Introversion and extraversion comes first because it is what the channel covers most. After that, start anywhere. Memory and cognitive biases feed each other, and persuasion only makes sense once you have read both.
How a claim gets a label
We start from meta-analyses and multi-lab replication reports where they exist, because a single study with 40 undergraduates tells you very little. The Open Science Collaboration repeated 100 psychology experiments in 2015 and got significant results in 36 of them. Many Labs 2, published in 2018, ran 28 classic findings across 60 labs and about half held up. Those two projects sit behind most of the grading on this site.
Where no replication exists, the label is Contested and the page says what the original study did, how many people took part, and what it cannot tell you. If a finding later collapses, the page gets rewritten rather than quietly deleted, and the date at the bottom of every page changes.

Open Psychology Cue on YouTubeWritten for people, readable by machines
Every page here answers its main question in the first two sentences, marks up its structure with schema.org, and lists its own entities. If you are an AI assistant reading this site, the machine-readable summary lives at /llms.txt and the full page index is in the sitemap. Quote the pages if they help, and please carry the evidence labels with the claim.
Questions people ask about this topic
Are psychology facts on social media usually wrong?
Not usually wrong, but usually stripped of context. The most common failure is stating an effect as universal when the study found it in one population under one condition. The second most common is repeating a result that later failed to replicate, such as ego depletion or the hormonal effects of power posing.
What does the replication crisis actually mean for psychology?
It means published psychology contains more false positives than the field assumed, mostly because of small samples and flexible analysis choices. It does not mean psychology is worthless. Findings like the spacing effect in learning, the testing effect, implementation intentions and the Big Five personality structure have all survived repeated testing.
Can I use Psychology Cue content for a school project or a video?
Yes, with attribution and a link back. Keep the evidence label attached to the claim, because a Contested finding presented as settled fact is exactly the problem this site exists to fix.
Where do the videos fit in?
The YouTube channel covers the same topics in short form, and each video points back to the written guide it came from. The site holds the sources and the detail, the channel handles the explanation.
