Every link on this page was real. The manager banned late-night emails and the deadlines kept slipping, because burnout made both — and neither the emails nor the deadlines could reach it.
The link was strong, repeatable and real. Late emails were banned, and the deadlines carried on slipping.
Late-night emails and missed deadlines rise together, across nine months and four teams.
Late-night emails are banned. Nine months later the deadlines are slipping at the same rate.
One says two things move together. One says pulling the first one moves the second.
The test is not whether the link is real — it usually is. The test is whether acting on it changes anything. Every failure here belongs to somebody who acted: banned the emails, hired the locals, bought the mentions, added the supervisors. The pattern held. The action did nothing.
What breaks the connection is a third thing driving both. Burnout makes late emails and missed deadlines. A season makes mentions and sales. Pull either visible end and the hidden middle carries on producing them.
Tap a link, then tap whether acting on it would change anything. Then see what happened when somebody did.
Pick a situation. Every one of these links held up in the numbers.
Late emails and missed deadlines rose together for months. Burnout produced both, and the ban removed the sign while leaving the cause exactly where it was.
Five questions. Nothing is scored.
Five terms, not two. Tap one.
Check if the report shows only a pattern or proves one thing made the other happen. Look for experiments, controls, or other evidence that rules out other causes. If only a pattern is shown, it is correlation.
A confounder is a hidden factor that influences both variables being studied. For example, ice cream sales and sunburns both rise in summer, but the real confounder is the weather. Ignoring confounders leads to wrong conclusions.
AI models are designed to find patterns and links — correlations. Proving causation usually needs controlled experiments or extra checks outside the data. Most AI research stops at correlation unless it includes special testing.
Confounders hide the real cause behind a pattern. Acting on the wrong link wastes time and resources. For example, changing a process based on a pattern that was caused by something else will not fix the real issue.
A team notices that projects with more meetings finish faster. They add meetings to all projects, but timelines do not improve. The real cause was that urgent projects got more meetings, not that meetings sped up work.
| Evidence type | Correlation | Causation |
|---|---|---|
| Pattern in data | Yes | Maybe |
| Controlled experiment | No | Yes |
| Random assignment | No | Yes |
| Direct mechanism | No | Yes |
AI models are trained to spot patterns, not reasons. Reports can sound convincing because the numbers line up, but the model cannot check for hidden causes or run experiments. The writing looks the same, so the difference gets missed.
A pattern tells you where to look. Only a cause tells you what to change, and the gap between them is measured in things that did not work.
