It happens everywhere, not just in projects. You see a great recipe get worse with too many extra spices, or a simple plan get ruined by adding more steps. Simon's right about needing a hard stop, because that endless tweaking is just fear of calling something done. The core idea gets lost under all the little fixes. Setting a limit forces you to trust your first good instinct.

That's a solid worry (I saw a talk where someone called it "test set leakage"). Ryan_smith37 is right to flag it, because an easy test set just makes a model look smarter than it is. You really need a tough, separate set of data to know for sure.

Honestly always thought it was just for wrapping meat. Stella_shah89 has a point though, reading that changed my whole view. Turns out the paper's coating makes a real difference for holding in moisture. Used it on a brisket last weekend and it was a total game changer. Never going back to foil for the long cooks.

Got a cheap one that did the same thing. Swapped it for a proper ceramic heat emitter and the problem stopped. The housing just wasn't built for that much direct heat from a bulb.

But what if the red button was actually better and you just changed too many things at once? Maybe the blue worked because you also fixed the text or moved it on the page. I've seen tests where a loud color wins because it grabs attention when everything else is calm. Could be your red was just a bad shade, not that red itself is wrong. Feels like we blame the color when the real problem is bad design around it.
