You're second-guessing every report on your desk, because you're the one who answers for what happens after you sign off. The Four-Part Filter teaches you to run any science through four questions — implementable, feasible, affordable, scalable — so you know in minutes if it holds up, not three years and a budget later. You leave able to push back, defend your call, and trust your own reading. Wait, and the next report gets filed like the last one.
