Schools do them, hospitals do them, airlines do them, and the military does them obsessively. Almost no one else does. Most workplaces run a fire drill once a year if they remember, evacuation rehearsals are virtually unknown in private homes, and active-threat or medical-emergency simulations tend to happen only after an incident has already exposed the gap. The reasons drills get skipped are predictable, and so are the consequences.
When a real emergency hits, performance falls back to whatever was practiced. If nothing was practiced, performance falls back to confusion.
The cost-benefit conversation that never happens
Drills feel expensive. They take time off the schedule, interrupt revenue-generating work, require coordination, and produce no visible output. The benefit is invisible by design—it’s the bad outcome that didn’t happen, which is hard to notice and impossible to bill for. Managers asked to justify a quarterly evacuation drill against a backlog of customer requests almost always concede the drill. Households face the same calculus on a smaller scale: rehearsing a fire escape route on a Saturday morning competes with everything else a family might be doing, and the perceived probability of a real fire is low enough that it loses every time. The expected-value math actually favors drilling, because the cost of being unprepared is catastrophic, but the framing makes the small certain cost look bigger than the rare large one.
Embarrassment, awkwardness, and the social tax
Drills are also socially uncomfortable, especially the realistic ones. Standing in a parking lot at 10 a.m. while someone takes attendance feels silly. Practicing CPR on a mannequin in front of coworkers is awkward. Running through what to do during a violent intrusion forces conversations that organizations avoid for cultural and emotional reasons. Households don’t want to scare children with vivid disaster scenarios, even though research consistently shows that age-appropriate practice reduces panic and improves outcomes. The friction is real, but the workaround is design: short drills, normalized as routine rather than alarming, lose the social charge after a couple of repetitions. Aviation crew resource management figured this out decades ago.
What actually works when drills happen
The drills that produce results are the ones that introduce realistic constraints. Blocked exits force participants to find alternates. Communications failures force decision-making without the usual channels. Surprise timing—rather than the same Tuesday morning every quarter—reveals which people actually know what to do versus which ones followed last time’s leader. Debriefs matter as much as the drill itself; the moment afterward, when participants identify what was confusing or slow, is where the learning lives. Organizations that take this seriously also rotate scenarios, so the team isn’t just rehearsing one event but building general adaptive response. Households that run two or three short scenarios a year see measurable improvements in response time.
The takeaway
Drills get skipped because they look like cost without obvious benefit, and because they’re socially awkward. Both problems are solvable with normalization and good design. The alternative is discovering, in the worst possible moment, exactly what hasn’t been practiced.
