We asked 28 marketers what single change in their ad account made the biggest difference - and nobody put creative at the top. What came back instead was account structure, cost caps, better data, and one answer that stopped us cold: doing nothing at all. This episode breaks down the nine cognitive biases quietly running the average media buyer's decisions, from action bias to the expert's curse. We get into why excluding past purchasers dropped one brand's new customer CPA by 40% overnight, why "data-driven" has become a red flag on a resume, and why the last 20% of Meta optimization is worth less than the first 20% of your landing page. If you manage ad accounts, hire people who do, or spend your Sundays reorganizing campaigns you shouldn't be touching, this one's for you.
