The Risk and Management of Record Chasing
The pursuit of deep diving records is an unsettling but accepted facet of tech diving culture. On the one hand, we are driven as a species by our genetic predisposition to “Go Where No One Has Gone Before.” Blame it on our DRD4-7R explorer gene! On the other, many question the value and legitimacy of conducting a high risk, touch-and-go line dive for recognition and bragging rights alone. Where and how do we reconcile the two? Here diving physiologist Neal Pollock seeks to answer those questions in a compelling, principled exposition that may help you to sharpen your beliefs.

Humans have probably been chasing records as long as we have existed. Og was almost certainly proud of discovering that two stones could be rubbed together to make fire, and it likely resulted in a solid community standing for at least a while. Tempting though it may be, we cannot blame our interest in records on the advent of the Internet or social media. The Guinness Book of World Records, a small example of documenting novelty, was first published in Great Britain in 1955. The Internet and social media, however, have made the striving for and tracking of new records more intense.
Record making is well established in diving as well as in most other communities. There are interminable lists of the first makers of equipment, the first to implement or explore, and the most extreme doers of deeds. History shows them to be pivotal, meaningful, or trivial as it unfolds. Keeping the record straight is important, but the decision as to why and whether to pursue records is worth debating.
I am a fan of documenting meaningful events, but I have concerns over an excessive focus on arbitrary milestones. When a community puts more weight on records than actual achievements, the drive can become pointless or problematic. The pointless includes many Guinness records, such as the most number of people brushing their teeth simultaneously and the largest rubber band ball.
While some in the diving community have pursued fairly pointless but low risk records, it is the problematic ones that are a much greater concern. Underwater activities involve greater risk than many other endeavors, relying on equipment, training, technique, and practice to produce an envelope in which reasonable levels of safety can be maintained. Pursuing records is generally about pushing boundaries, and when the boundaries are set by the interaction of physics and physiology, the erosion of safety buffers can produce serious risk. The pursuit of targets can overwhelm well-founded safety concerns and common sense.
“Record chasing can produce good outcomes, and some meaningful achievements, but when going forward is reliant on misplaced beliefs that personal motivation and superiority can overcome unforgiving limits, the outcome can be bad for both individual and community, even if considered successful.”
Record chasing can produce good outcomes, and some meaningful achievements, but when going forward is reliant on misplaced beliefs that personal motivation and superiority can overcome unforgiving limits, the outcome can be bad for both individual and community, even if considered successful.

One of the chief challenges in diving is that the interaction of physics and physiology creates difficult-to-define limits. There are differences in tolerance between individuals and often between exposures. Different breathing gas mixtures can alter narcotic potential, respiratory gas density, decompression stress, and susceptibility to oxygen toxicity and high pressure nervous syndrome, among other concerns. Differences in workload, stress, physical fitness, and physical skill can also alter the response to other more fixed stressors. Practically, the interactions between the host of factors is complex and can make the element of chance more important than people would like to admit. A scary reality of many boundary-pushing events is the fact that getting away with something once, or even multiple times, does not necessarily make it safe, and almost certainly not safe for all.

Records achieved with a large helping of good luck still count, but they can be extremely troubling if others are encouraged to try to surpass them. Not only can tolerance and good fortune differ, the lessons learned in building to “record” performance may not be appreciated by those who follow, potentially magnifying the risks.
Care is warranted to decide on what “records” are truly worth pursuing and what should be left alone. A simple practical test is whether an activity serves any purpose beyond the record attempt. If there is no other benefit or purpose, the value in it may not be sufficient to continue, especially when the associated risks may be high.

Record attempts are sometimes pursued by relative newcomers to a field. It is unclear how much of this is due to simple enthusiasm or a desire to stand out, but all such efforts are best met with counsel before encouragement. The field needs leaders, and the next generation of leaders, but this requires keeping those with potential both healthy and engaged. This may come down to mindset—finding what is most important and appropriate to pursue as part of personal growth.
Leaders who want to establish themselves are best served by ensuring that they have the best understanding, skill, and experience within the realm of what they will need to do rather than pushing the envelope for increased fame. Chasing records by sacrificing safety margins and/or ignoring compromised states of affairs is not compatible with accepted best practice. Those looking up to leaders for inspiration may not fully appreciate the issues and concerns, but the best leaders will be conscious of the total impact their efforts can have on others.

Bragging about exceptional or record exploits is problematic in that it can encourage others who may be inadequately prepared to follow suit. It may be a hard reality for the keen, hungry, and superbly confident instructor to accept, but they can provide a much better service to their students by encouraging them to stay within the accepted realm of operational safety. This is often most effectively demonstrated through example. The goal should be to promote a long and healthy diving life, effectively achieved by solid training and an instilled appreciation for the value of robust safety buffers and a constant revisiting of “what if” preparation.
We should recognize the meaningful efforts in the community, but without losing sight of the implications of such endeavors. Promotion of a positive safety culture requires questioning whether things should be done, and how things that should be done can be done with appropriate safety margins. If meaningful efforts result in record achievements they should be applauded, but always with an appropriate framing of any associated value, limitations, hazards, and implications.
Reporting the exceptional is important, but a high priority should also be put on recognizing activities and efforts that are unexceptional in outcome due to appropriate preparation and execution within safe boundaries. Efforts to improve training, awareness, and operational safety must always be promoted. Safety programming is challenging since, when it is effective…, nothing happens. Ongoing commitment is required to ensure that it continues to be effective.
I would posit that the best record attempts are those pursued without fanfare, moving quietly from concept through to safe workup stages and then safe completion. The reporting of record efforts should always consider the value and relevance of the activity. Achievements that violate the criteria for safe performance should be neither encouraged nor glorified.
We live in a time when the pursuit and promotion of records can be expected to continue, but appropriate framing can help to ensure that the community benefits from a sustained focus on safety and thoughtfulness.

Why It’s Okay To Make Mistakes
To err is human. To trimix is divine? Instructor evaluator Guy Shockey examines the importance of learning through one’s mistakes, and most important, being willing to admit and share them with others, especially for those in leadership positions. It’s the only way to create ‘psychological safety” within our community and improve our collective diving safety and performance. Wouldn’t that be divine?

A few months back, I read an article about a club where members talked about failure and making mistakes. This club required that members freely discuss their mistakes and failures without fear of judgment. The goal was to destigmatize failure and recognize that we learn by making the very mistakes we are afraid to talk about! Moreover, to become truly high performing and develop unique and creative solutions to problems, the article argued that we needed to be free of the worry of failing—to understand that “to err is human.”
The article went on to mention that for high performing teams to be successful, they needed to operate in an environment of “psychological safety.” This term was originally coined by Harvard professor Amy Edmondson, and Gareth Lock has written about the concept extensively. In his work with The Human Diver, Lock identifies psychological safety as a key component primarily missing in our diving culture. As a full-time diving professional and someone who delivers The Human Diver programs, I couldn’t help but reflect on the failure-destigmatizing club in the context of our diving culture in general and, more specifically, dive training.
Consider the humble Roomba robot vacuum cleaner. The Roomba learns how to clean a room by bumping into nearly everything in the room and, with some nifty software, creates a “map” of all the “vacuumable” space in the room. Then, it goes about its business efficiently and repetitively cleaning the room. The Roomba has learned by making multiple mistakes—much like humans do.
Now imagine being able to transfer that new “map” from one Roomba to another so a new Roomba doesn’t have to repeat the mistakes of the first as it sets out to vacuum the room. Finally, imagine this transfer of data to be less-than-perfect—perhaps, occasionally, the new Roomba will make some mistakes (from which it will learn). But it will make far fewer mistakes than the original Roomba had to make.
I’m sure you can see where I’m going with this. Humans learn the same way Roomba vacuums do (hopefully without running into as many hard surfaces), and we can transfer information between each other. Because the transfer process is less than perfect, we still make some of the same old mistakes. This is particularly interesting because, despite drawing specific and repeated attention to these common errors, students often still make the same errors! One of the most important parts of instructor training is educating future instructors to recognize where these common mistakes will occur and encouraging them to ramp up to being hyper-vigilant rather than regular-vigilant.

Learning Through Mistakes
One way we learn is by making mistakes, talking about them, and sharing the experience in the hopes that future divers don’t have to make the same ones. At its core, this is the very essence of learning. Incidentally, this is also what makes experience such an important characteristic of a good teacher. The more experience the educator has, the more mistakes they’ve made and, consequently, the more information they can transfer. Fear of owning our mistakes keeps us from learning from them; perhaps more importantly, it means that others will miss out on these important lessons.
Yet, in diving culture, we (for the most part) shy away from discussing the mistakes and errors we (hopefully) learned from for fear of being considered a less than capable diver. When divers in influential or leadership roles do this, it is a tremendous loss for the diving community in general—it robs future groups of divers of the opportunity to learn. Sadly, because this commonly happens at the leadership level, it is hardly surprising that other divers further down the line copy that behavior, and we ultimately end up with a diving culture that emulates the example of the leadership.
I advocate for taking the opposite approach. In my teaching, I am very open about the mistakes or errors I have made while diving. I recognize that I am basically a smart Roomba, and I learn by making mistakes. Thus, it would be disingenuous to pretend that I don’t make mistakes—I had to learn somewhere! I believe this approach lends authenticity to my instruction and starts to create psychological safety in my classes. Ultimately, my goal is to encourage students to recognize that, “If the instructor can admit they make mistakes, then it is okay to talk about the ones our team made during the training dive.”
I have found that there is a remarkable change in the relationship between student and instructor when this happens. Learning becomes more of a collegial activity, and stress and performance anxiety significantly decrease. This leads to more successful learning outcomes and happier students. I am a firm believer that, while training can be serious, it should also be fun!
Creating Psychological Safety
Creating psychological safety in our diving culture is a daunting task, but every flood begins with a single raindrop. The first thing that needs to happen—at all levels—is an acknowledgement of failures and mistakes among those in positions of influence and leadership. Sadly, this is not as easy as it sounds, and there is frequent pushback. Ego is one of the most dangerous aspects of a personality and it frequently causes people to overreach, crippling growth and learning. The irony here is that every single one of us has made a mistake. We all understand that no one is perfect, yet many in leadership positions cling to the view that vulnerability is weakness—that demonstrating imperfection will cause others to stop trusting them (or revering them).
I propose that the opposite is true. I should also note that I believe every dive professional is acting in a leadership role. This means that, while creating psychological safety can best be started by those in senior leadership roles, it must also be encouraged at all levels of leadership, including anyone in supervisory or teaching roles. In a perfect world, every diver would embrace this approach and enable psychological safety within their team.
There are a few things you can do to help develop psychological safety. First, facilitate a debrief at the end of the dive and begin with “something that I as the leader did wrong or could have done better was…” This immediately creates fertile soil for psychological safety to flourish. When the leader is the first person to say, “I made a mistake,” it establishes that this is a safe place to discuss mistakes and errors with the intention of learning from them. This opens the door to follow-up discussions.
On the subject of transparency, in any organization it is often the voice of dissent—a contrary position—that is the most valuable. This voice causes the group to reflect on original assumptions and decisions and offer a perspective that “groupthink” does not. This means that we need to be open to different solutions to problems lest we be blinded by our own cognitive biases—ones that have been developed over thousands of years of evolution in order to make us more efficient Roombas.
We are essentially fighting against our own brains, and it takes a significant amount of effort to think outside the box. We are hard-wired to think in terms of “evolutionary” rather than “revolutionary” ideas, and we need to make a conscious effort to consider the voice of dissent and understand why it is so hard to do so.

In Conclusion
In psychologically safe environments, we experience a significant increase in “discretionary effort,” or shifts on the “need to do” and the “want to do” curves. If a team has a high degree of psychological safety, they are motivated to perform higher than the minimum standard. If you create a high degree of psychological safety, your team will perform better as a result.
This is where it all comes full circle. We want our dive teams to perform at a high level. We want them to have a high degree of discretionary effort. We want them to embrace our “commitment to excellence.” Therefore, we must be the ones to create the psychological safety necessary to facilitate this growth.
One of the most effective things you can do as a leader is to be open and willing to share that, in the end, you are human too. You make mistakes, you admit to them, you learn from them, and you share them with others so they can learn too.
