“A study found it” is where the question starts — not where it ends.

Noa and the one weird trick
Noa — sixteen, three exams away, a video promising a "science-backed 5-second trick to feel confident"
The video has ten million views. A confident voice says "psychologists PROVED that forcing a smile makes you feel better — try it before your exam." Noa's thumb hovers over share.
The smile trick is a real study — Strack, 1988. It is also the textbook case of a finding that did not survive: when seventeen labs ran it carefully in 2016, the effect vanished, and a bigger 2022 study found the pen version inconclusive again. Only a small posed-smile effect held up.
That is not a gotcha about psychology; it is psychology working. The field checks itself, and "it replicated" is a different, stronger claim than "a study found it once."
Noa does not have to become a cynic. The skill is smaller and kinder than that: hold the headline lightly, and ask whether it held up — before you build your exam morning on it.
What does Noa do with the video?
Psychology is a science because it checks itself. Knowing which findings held up — and which famous ones did not — is worth more than any single "one weird trick".

Kiran and Noa check the smile study
Kiran & Noa — sixteen, Noa's lab partner, who read that holding a pen in your teeth makes cartoons funnier
Kiran found a famous study: people holding a pen between their teeth (forcing a smile) rated cartoons as funnier. Then Noa found that in 2016, seventeen labs repeated it carefully and did not find the effect.
Replica's job is to run a finding again elsewhere. When careful repeats find the same thing, confidence goes up.
Null is the honest empty result. Later studies with different methods found small effects under some conditions, which is why the question is still being studied.
What should they write in their project?
One study is a claim. A replication is how a claim becomes knowledge, or does not.

Ezra and Noa test a trick on themselves
Ezra & Noa — sixteen, convinced that a breathing trick from a video makes him calmer before tests
Ezra swears the "box breathing" video calms him before every test. Noa asks how he would know whether it is the breathing or the fact that he believes in it.
Priming is the effect that feels real because you expected it. That does not mean the trick does nothing; it means feeling better is not proof on its own.
Baseline is your own one-off read: how you feel before, without the trick, for comparison.
How should Ezra find out?
Feeling that something works is the start of a question, not the end of it.
