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.

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.
