Cherry Picker
Slice a dataset into subgroup after subgroup until chance hands you p < 0.05 — then watch a fresh sample decide whether your finding was real or a fluke.
How to play
The treatment has no real effect, so any significance you find is noise. Filter the data into subgroups and re-run the test as many times as it takes to stumble onto a p-value below 0.05, then submit your 'finding' to the referee. The twist: a replication check draws a fresh independent sample and re-tests your exact claim. Real effects survive; p-hacks vanish — and that gap is the whole lesson.
- Each Run Test slices the data and reads a live p-value.
- An Auto-hack button fishes across many subgroups for you.
- Your score reflects honesty, not just finding significance.
Controls
- Desktop: click subgroup chips to filter, then Run Test, Auto-hack or Submit.
- Phone & tablet: tap the chips and buttons — fully touch-friendly.
Game modes
- Daily and Practice modes, each in Easy, Medium or Hard difficulty.
Tips & strategy
- Notice how many comparisons it took — the more you ran, the less your 'significance' means.
- A finding that barely clears p < 0.05 on a tiny subgroup almost never replicates.
