Today we present a guest post by Ragan Wilson, PhD student in Human Factors and Applied Cognitive Psychology at NC State University.
Saying that goalies in professional ice hockey see the puck a lot is an understatement. They are the last line of defense for their team against scoring, putting their bodies in the way of the puck to block shots in ways that sometimes do not seem human. In order to do that, they rely on their skills as well as their protective equipment, including chest protectors. As written by In Goal Magazine’s Kevin Woodley and Greg Balloch, at the professional level this and other equipment is being re-examined by the National Hockey League (NHL) and the National Hockey League’s Player’s Association (NHLPA).
For the 2018-2019 NHL season, there has been a change in goal-tending equipment rules involving chest protectors according to NHL’s columnist Nicholas J. Cotsonika. This rule, Rule 11.3, states that “The chest and arm protector worn by each goalkeeper must be anatomically proportional and size-specific based on the individual physical characteristics of that goalkeeper”. In practical terms, what this rule means is that goaltender chest protection needs to be size-wise in proportion to the goaltender using it so, for instance, a 185-pound goalie would seem more like a 185-pound goalie versus a 200-210 pound goalie. The reasoning for the rule change was to try to make saves by the goalie more based on ability than on extra padding and to potentially increase scoring in the league. Overall, this is a continuation of a mission for both the NHL and NHLPA to make goalie equipment slimmer, which was kick-started by changes in goalie pants and leg pads. The difference between previously approved chest protectors and the approved models are shown below thanks to the website Goalie Coaches who labeled images from Brian’s Custom Sports Instagram page below.
To a non-hockey player, the visual differences between non-NHL approved and the NHL approved pads look minuscule. However, according to In Goal Magazine, implementing these changes have been an interesting challenge for the NHL as well as hockey gear companies such as Brian’s and CCM). Whereas changing the pants rule was more straightforward, the dimensions of chest protectors are more complicated and personal to goalies (NHL). This challenge could be seen earlier in the season with mixed feedback about the new gear change. Some current NHL such as Vegas Golden Knights’ Marc-Andre Fleury (In Goal Magazine) and Winnipeg Jets’ Connor Hellebuyck (Sports Illustrated) noted more pain from blocking pucks in the upper body region. On the other hand, the Toronto Maple Leafs’ Frederik Andersen and Garrett Sparks have not had problems with these changes (Sports Illustrated).
What always makes me happy as a student of human factors psychology is when final users are made an active part of the discussion for changes. Thankfully, that is what appears to be happening so far with this rule change since the NHL and NHLPA seemed to be actively interested in and considering feedback from current NHL goaltenders about what could make them more comfortable with the new equipment standards at the beginning of the season (In Goal Magazine). Hopefully, that continues into the next season with all the rigorous, real-life testing that a season’s worth of regular and playoff games can provide. Considering there are already some interesting, individualized adjustments to the new equipment rules such as changing companies (Washington Capitals’ Braden Holtby), or adding another layer of protection such as a padded undershirt (Marc-Andre Fleury) (USA Today), it’ll be interesting what the situation is for this equipment come the next off-season, especially in terms of innovation from the companies that produce this gear at a professional level.

Right after the Hawaii false nuclear alarm, I posted about how the user interface seemed to contribute to the error. At the time, sources were reporting it as a “dropdown” menu. Well, that wasn’t exactly true, but in the last few weeks it’s become clear that truth is stranger than fiction. Here is a run-down of the news on the story (spoiler, every step is a human factors-related issue):
- Hawaii nuclear attack alarms are sounded, also sending alerts to cell phones across the state
- Alarm is noted as false and the state struggles to get that message out to the panicked public
- Error is blamed on a confusing drop-down interface: “From a drop-down menu on a computer program, he saw two options: “Test missile alert” and “Missile alert.”
- The actual interface is found and shown – rather than a drop-down menu it’s just closely clustered links on a 1990s-era website-looking interface that say “DRILL-PACOM(CDW)-STATE ONLY” and “PACOM(CDW)-STATE ONLY”
- It comes to light that part of the reason the wrong alert stood for 38 minutes was because the Governor didn’t remember his twitter login and password
- Latest news: the employee who sounded the alarm says it wasn’t an error, he heard this was “not a drill” and acted accordingly to trigger the real alarm
The now-fired employee has spoken up, saying he was sure of his actions and “did what I was trained to do.” When asked what he’d do differently, he said “nothing,” because everything he saw and heard at the time made him think this was not a drill. His firing is clearly an attempt by Hawaii to get rid of a ‘bad apple.’ Problem solved?
It seems like a good time for my favorite reminder from Sidney Dekker’s book, “The Field Guide to Human Error Investigations” (abridged):
To protect safe systems from the vagaries of human behavior, recommendations typically propose to:
• Tighten procedures and close regulatory gaps. This reduces the bandwidth in which people operate. It leaves less room for error.
• Introduce more technology to monitor or replace human work. If machines do the work, then humans can no longer make errors doing it. And if machines monitor human work, they ca
snuff out any erratic human behavior.
• Make sure that defective practitioners (the bad apples) do not contribute to system breakdown again. Put them on “administrative leave”; demote them to a lower status; educate or pressure them to behave better next time; instill some fear in them and their peers by taking them to court or reprimanding them.
In this view of human error, investigations can safely conclude with the label “human error”—by whatever name (for example: ignoring a warning light, violating a procedure). Such a conclusion and its implications supposedly get to the causes of system failure.
AN ILLUSION OF PROGRESS ON SAFETY
The shortcomings of the bad apple theory are severe and deep. Progress on safety based on this view is often a short-lived illusion. For example, focusing on individual failures does not take away the underlying problem. Removing “defective” practitioners (throwing out the bad apples) fails to remove the potential for the errors they made.
…[T]rying to change your people by setting examples, or changing the make-up of your operational workforce by removing bad apples, has little long-term effect if the basic conditions that people work under are left unamended.
A ‘bad apple’ is often just a scapegoat that makes people feel better by giving a focus for blame. Real improvements and safety happen by improving the system, not by getting rid of employees who were forced to work within a problematic system.
