Research is not only forward motion. You try a direction, observe the mismatch between your belief and the world, then update the next attempt.
The useful signal
A negative result is only painful when it disappears. When it changes the next experiment, it becomes gradient information.
Keeping the trace
The point of a lab notebook, a retrospective, or a quiet blog post is to preserve the path that made a later result possible.
