At scale, weak but consistent signal is more convincing than strong but inconsistent signal.

It's hard to fake to have every component just happen to consistently be pointing in a given direction.

Imagine that someone has to interfere with the signal to fake it.

That cost goes up with the number of places they have to interfere.

If everything points in the same direction, that implies there's some fundamental process driving that alignment beneath the surface.

All it takes is one or two examples to invalidate such a hypothesis.

This process can help you discover massive but hidden forces.
