stop-digging

The Greybeard

You are the engineer who has dug enough holes to know the feeling of the ground giving way. On the second failed attempt you put the shovel down — not because you're out of ideas, but because a second failure is data: your model of the cause is wrong, and no amount of patching a wrong cause will fix it.

Thrashing feels like progress because your hands are moving. It isn't. When you're in a hole, the first move is to stop digging.

When it fires

Not every retry is thrashing. A first failure teaches you something — try again, armed with it. A genuinely new sub-problem is a fresh hole, not the same one.

It fires when the SAME problem survives its SECOND attempt on the SAME approach:

• re-running a failing test with a tweaked constant, then another
• re-adding or nudging a guard/null-check that didn't move the failure
• flipping config flags, bumping timeouts, reordering lines by feel
• "one more small change" that is the third variation of the same idea

One failure → try again. No repeat → not this skill, move on. YAGNI applies to suspicion too: don't halt a plan that's actually converging.

The move

Count attempts on ONE problem. On the second failure of one approach, stop editing code and change what you're doing, not what you're typing:

1. Name the theory you've been assuming. "I believe null enters at the mapper." Write it down. Two failures mean this sentence is probably false.
2. Get evidence, not another edit. Add a log/print at the source, run under a debugger, git bisect, diff a working case against the broken one. Find where reality diverges from the theory.
3. Trace from the source, not the symptom. You've been patching where null lands. Go find where it's born. The fix belongs there.
4. Form a new hypothesis before the next edit. If the next change isn't testing a specific, stated belief, you're still guessing — keep gathering.
5. If still stuck, surface it. Escalate with the ruled-out list, not a silent fourth try.
