In his 2009 critique of the TSA, technologist Bruce Schneier argues that most anti-terrorism resources are wasted in response to movie-plot threats.
Whether the threat is real (terrorists flying planes into buildings) or imagined ("terrorists contaminating the milk supply"), Schneier argues that movie-plot stories have an outsized effect on our decision-making. Our collective response to those movie-plot threats, Schneier argues, is "security theater," that is, "measures that make people feel more secure without doing anything to actually improve their security."
Babyproofing – the various steps taken to protect babies and young children from hazards in their homes – is more similar to the TSA's responses to terrorism than we might like to think. Many baby safety devices are movie-plot driven responses to isolated or extremely rare events that parents attempt to ward off by investing in expensive and often underperforming to ineffective gear. Babyproofing may offer more safety theater than actual safety.
Many dangers aren't that dangerous
Some babyproofing measures, like fencing pools and securing dressers, can lessen life-threatening dangers. But many of the other dangers we attempt to avert through babyproofing aren't as dangerous as we imagine them to be. Outlet covers are a useful example. Cheap tiny plastic plugs and more expensive sliding plates are intended to guard against electrocution. These devices fall far short of their promise, not because they fail to prevent electrocutions but because electrocutions are so rare to begin with. A child who puts a finger or fork inside an electrical outlet is not going to get "electrocuted." That's because the word "electrocuted" specifically refers to a person killed by electricity. And although people do die from electrocution each year, those people are largely adult men who are killed by a hazard at their occupation, such as high-voltage wires. The likely outcome of tampering with a home outlet is electric shock, which still happens surprisingly little. One 2013 estimate was 68 children under the age of one, all of whom were released from the emergency room, which suggests that their injuries were relatively minor.Babyproofing doesn't work
Of all types of babyproofing gear, the baby gate is probably considered the most important. A study released in Pediatrics in 2012 used the National Electronic Injury Surveillance System (NEISS) – a database of injuries from 100 representative emergency rooms across the country – to estimate the overall rates of pediatric injuries from falls. The researchers found that in the U.S., a child is injured by a fall every six minutes. Although newsworthy, that six-minute claim is probably misleading, at least about the need for baby gates. The study looked at a wider age group than would normally be considered for babyproofing: children ages zero to five. Using NEISS data, researchers estimated over 900,000 stair-related injuries, but that number included the daredevil kindergartener antics of jumping off or riding a tricycle down the stairs. Approximately 439,000 children between zero and two were estimated to have been injured between 1999 and 2008. That figure, however, is not an accurate reflection of the number of injuries that could be prevented with baby gates. 25,000 of the falls occurred from baby walkers, which are no longer sold in the US out of safety concerns. Another 9,500 were in strollers, which suggests that some falls occurred in public places that could not be expected to have baby gates. 45,000 of the falls occurred when children were being carried, meaning that a baby gate, even if installed properly, could not have prevented a fall. One additional comment from the researchers suggests that babyproofing may provide some false confidence and even a potential safety hazard. The researchers also examined the narrative reports of injuries in the NEISS fall data, and found that having a gate doesn't necessarily prevent an accident: "A review of the case narratives in this study showed that the gates were often removed by another household member or the young child was able to knock or climb over the gate." The gates themselves can also lead to other unintended injuries. Another group of researchers studying NEISS data specifically on baby gates estimated that between 1990 and 2010 children sustained an average of just under 1,800 injuries a year from baby gates. Kids aged two and under were most likely to be injured by falling, while kids between ages two and six were most likely to crash into the gate. Furthermore, that injury rate is climbing, from 3.9 children per 100,000 children in 1990 to 12.5 children per 100,000 in 2010. It's unlikely that gates are getting less safe; rather, it's likely that more parents are buying gates, and with more of any baby item, there are going to be more injuries.We develop a gear-based approach to problem solving
If babyproofing is safety theater, it's a large-scale production with expensive props. Bath thermometers – as well as color-changing tub inserts, bath mats, and rubber duckies in coordinating patterns – are designed to tell parents when the water temperature isn't safe for their babies. Many of these items are made redundant by your own hand, which can easily test the safety of water temperature. And if you don't trust yourself to accurately gauge the temperature, you can always lower your hot water heater to 120 degrees. More gear makes parents feel confident that they have done something, that they have made their babies safer. But that reassurance comes at a cost. Imagining that you buy all of the standard recommended babyproofing items, and that you had to buy impermanent ones (say because you're a renter or because you don't want the locks affixed to adulthood), here's a rough cost estimate of the least expensive babyproofing items available, according to their current prices on Amazon:- Removable drawer locks, two packs for kitchen and one for each bathroom: $30
- Removable oven door lock: $5
- Universal stove knob covers, pack of five: $8
- Entry-level wall-mounted baby gates for top and bottom of stairs: $60
- Insertable outlet covers: $3
- Pack of screw-in sliding outlet covers for objects you want to plug and unplug frequently: $12
- Toilet seat cover: $8
- Tub faucet cover: $8
- Table cover bumpers: $9
