The Human Diagnostic
Looking for honest stories about people, not product reviews? You're in the right place.
The Human Diagnostic isn't a how-to HVAC podcast. It's what a 45-year Master Technician notices about people after 90,000 service calls across gas plants, oil rigs, hospital preservation systems, high-rises, feedlots, walk-in freezers, and residential homes all over Central Oklahoma.
Hosted by Dave Hartzell, each episode tells a real story from a real service call. Sometimes he's driving to the job and predicting what he's about to walk into. Sometimes he just left and he's still working through what he saw. Either way, the story turns out to be about more than HVAC.
Topics you'll hear across the season:
β
The customer nobody wanted to take, and what changed when someone finally did
β
Why the person researching their broken AC at midnight isn't being difficult, they're scared
β
What 45 years of walk-ins, weddings, funerals, and broken water heaters teaches you about anxiety
β
The tech who can fix anything but can't explain it, and why the customer doesn't trust him
β
The review you can't place, the moment you never forget, the call that changed how you work
β
What gets lost when we treat people like tickets, and what gets found when we don't
Whether you fix things for a living, manage people who do, or just like good stories from someone who has been everywhere and met everybody, The Human Diagnostic gives you the part of the job that never shows up in an invoice.

Why Her Neighbor's AC Repair Stung More Than Her Own
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
There is a customer of mine who runs a small construction company in central Oklahoma. He is in his early fifties. Started his business at twenty-six with one truck and a partner who quit on him in 2002. Built the company through the housing crash and the years after.
He is good at what he does. His crews are reliable. His pricing is honest. His finishes are tight. His reputation has been earning him work for twenty years.
He is also, in his own words, hated.
We were sitting at his kitchen table after a system replacement and he was telling me about a competitor in his line of work who had been spreading rumors about him for about eighteen months. Stuff about pricing. Stuff about labor practices. Stuff that was not true and that he could not respond to without looking like a man who responds to rumors. He had been carrying it.
He said, the worse thing is, I'm not even mad at the guy. I get it. It is what people do when somebody is doing the thing they wish they were doing.
That sentence is what I want to talk about today.
There is a body of research on envy that has been refined a lot in the last twenty years. The most useful framework, in my opinion, is from a 2009 paper by three Dutch researchers, Niels van de Ven, Marcel Zeelenberg, and Rik Pieters. Their paper made a distinction that the older literature had not made cleanly. They proposed that envy comes in two distinct forms, and the two forms produce very different behavior.
The first form is what they called benign envy. Benign envy is the feeling, when you see somebody doing well, that motivates you to do better yourself. You see your friend get a promotion and you feel a small ache, and the ache turns into more effort at your own work. Benign envy, the research found, is associated with positive outcomes. It pulls people upward.
Core line: "I want to talk about what it is like to be on the receiving end of this, because most people who get there for the first time are not prepared for it."

Imagine for a second that you have uh finally achieved that one great thing you've been working toward for years.
SPEAKER_00Oh man. Yeah, like building a business from the ground up or something like that.
SPEAKER_01Exactly. Or, you know, maybe you finally landed that massive promotion you spent late nights preparing for. Or you just mastered a really complex skill that took thousands of hours of grueling practice.
SPEAKER_00Right. Just grinding it out.
SPEAKER_01Yeah, you grind it out, you cross the finish line, you look around, and you expect to hear the applause of the people closest to you.
SPEAKER_00Which is a totally normal expectation, by the way.
SPEAKER_01Totally normal. But instead of high fives and celebration, you are met with uh whispers, you start noticing little acts of sabotage. Ooh. Yeah. And the most painful part of this entire scenario is that the hostility is coming from someone you genuinely considered a friend.
SPEAKER_00Aaron Powell It creates a massive psychological dissonance. Yeah. I mean, you achieve the very thing you both talked about striving for, right? Right. And the reward for that achievement is this sudden, inexplicable coldness from your own circle.
SPEAKER_01It's confusing, it's isolating, and honestly, it just hurts. So for today's deep dive, we are pulling from a really fascinating stack of materials to figure out the hidden mechanics behind that exact betrayal.
SPEAKER_00And we have some incredibly grounded sources for this.
SPEAKER_01We really do. Our primary source is a set of personal notes and reflections from Dave Hartzell. So Dave is a master HVAC technician based in Kingfisher, Oklahoma.
SPEAKER_00We are talking about 45 years of hard-won experience in the trades here. He has seen every kind of human interaction imaginable.
SPEAKER_01Exactly. And he wrote this reflective essay titled The Customer Who Was Resented for Being Good At It. And to understand the heavy psychology behind Dave's ground level observations, we are pairing his notes with a landmark 2009 psychology paper.
SPEAKER_00Yeah, a paper specifically on envy.
SPEAKER_01Right, by a team of Dutch researchers, Niels van de Ven, Marcel Zeilenberg, and Rick Peters.
SPEAKER_00Which is great because we are putting the raw lived experience of decades in the trades right alongside the uh clinical structural mechanics of human emotion.
SPEAKER_01The mission for us today is to explore exactly why your success can cost you friendships. We want to look at why this quiet hostility isn't actually your fault and how understanding the hidden cognitive mechanisms of envy can finally, you know, free you from the guilt of outgrowing your peers.
SPEAKER_00But before we can dissect the clinical psychology of that 2009 study, we have to ground this in reality.
SPEAKER_01Yeah, we have to look at the people involved.
SPEAKER_00Exactly. We need to look at the very real, very painful case study that Dave Hartzel encountered on a routine service call. Because it just perfectly illustrates the human toll this takes.
SPEAKER_01Okay, let's set the scene. Dave is sitting at a kitchen table in central Oklahoma. He just finished replacing a system for a customer, and they get to talking.
SPEAKER_00Right, as you do.
SPEAKER_01Yeah. And this customer is a construction company owner in his early 50s, and his backstory is just the absolute definition of grit.
SPEAKER_00Oh, 100%. He started out at 26 years old with a single truck.
SPEAKER_01Just one truck. And then in 2002, his business partner completely quits on him, just leaves him to fly solo, absorbing all the debt and uh all the risk.
SPEAKER_00And then he single-handedly dragged this fledgling business through the absolute devastation of the 2008 housing crash.
SPEAKER_01Which in construction is just that's a nightmare.
SPEAKER_00A total nightmare. But he didn't just survive those hurdles, he built something of uncompromising quality. Dave's notes really emphasize that this man is genuinely undeniably good at his craft.
SPEAKER_01We're talking about a 20-year reputation built on honest pricing, incredibly tight finishes, reliable crews. He essentially became the gold standard in his local market.
SPEAKER_00Aaron Ross Powell Right. But instead of being universally respected for surviving decades of economic turbulence, he confesses today that he is, in his own words, hated.
SPEAKER_01Yeah, hated. For 18 straight months, a competitor in his exact line of work has been actively spreading false rumors about him.
SPEAKER_00Rumors about his pricing structures, rumors about his labor practices. Trevor Burrus, Jr.
SPEAKER_01Total fabrications designed to undercut his reputation.
SPEAKER_00Aaron Powell And the element that elevates this from a simple business annoyance to a profound personal betrayal is the history between these two men.
SPEAKER_01Right, because this competitor isn't an anonymous stranger. He's not a new rival from another town. They were trade friends.
SPEAKER_00They drank beers together at trade events. They came up in the exact same environment.
SPEAKER_01Aaron Powell And the customer tells Dave that the shift from being friendly to this outright malicious hostility happened so slowly, so gradually that he didn't even see it coming. Okay, let's unpack this. Because my first instinct, you know, when I hear about someone spreading lies about my business is to fight back.
SPEAKER_00Oh, absolutely. Defend your name.
SPEAKER_01Right. Call the guy out publicly, but he doesn't do that.
SPEAKER_00Well, the customer recognizes the agonizing trap of his situation. If he starts publicly fighting back against entirely false rumors, he suddenly looks, as he puts it, like a man who responds to rumors.
SPEAKER_01Wow. Yeah, that makes sense.
SPEAKER_00Fighting the noise validates the noise. It gives the accusations unearned weight.
SPEAKER_01And there's this profound, heavy sadness in his realization of why he is trapped. He tells Dave, and this quote is just brutal, he says, it is what people do when somebody is doing the thing they wish they were doing.
SPEAKER_00Man, that sentence is the anchor point for the psychological phenomena we are discussing today. We really have to acknowledge the emotional sting of that betrayal.
SPEAKER_01Losing a friend to pettiness is uniquely painful.
SPEAKER_00It is. But to survive the experience without internalizing the blame, we have to transition from the emotional pain to the structural cognitive mechanics of what is actually happening in the Ender's brain.
SPEAKER_01To understand a slow motion sabotage, we have to look at the mental gymnastics required to process another person's success.
SPEAKER_00Exactly.
SPEAKER_01But I mean, I push back on framing this purely as a psychological anomaly, though. In business, aren't people just cutthroat?
SPEAKER_00How do you mean?
SPEAKER_01Well, we are wired to compete for resources, right? You want market share, you take out the competition. Why do we need a complex psychological framework for a guy who just wants more customers and is using dirty tactics to get them?
SPEAKER_00It's a fair question. But standard competition doesn't target personal friendships in such an insidious, self-destructive way. Pure business competition is usually calculated to maximize personal gain.
SPEAKER_01Okay, I see.
SPEAKER_00The competitor's behavior we are looking at actively burns a useful network connection. And it risks their own reputation in the community if the lies are exposed.
SPEAKER_01So it's not rational business strategy.
SPEAKER_00Not at all. And that's where the 2009 Dutch psychological research completely redefines what is happening here. It shows that this isn't standard competition, it is a specific cognitive reaction to a perceived structural gap.
SPEAKER_01Which brings us to the research. Historically, you know, the older psychological literature treated envy as a single monolithic emotion.
SPEAKER_00Right. It was just envy, a universally negative, sinful feeling.
SPEAKER_01Yeah. But the paradigm shift from Van de Ven, Zelenberg, and Peters was identifying that envy actually comes in two structurally distinct forms.
SPEAKER_00Driven by entirely different internal triggers.
SPEAKER_01And producing wildly different behaviors.
SPEAKER_00So the first form is what the researchers termed benign envy. This is the upward-pulling manifestation.
SPEAKER_01It's that familiar, uncomfortable ache you feel in your chest when you see a peer succeed. Maybe they land the promotion you wanted.
SPEAKER_00Exactly. But instead of metastasizing into bitterness, the brain converts that ache into motivation. It translates into effort.
SPEAKER_01You put your head down, you study harder, you work longer hours to improve yourself.
SPEAKER_00Right. The research consistently associates benign envy with positive, constructive outcomes.
SPEAKER_01But then there's the second form, which is malicious envy. And this is the downward pulling form.
SPEAKER_00This is where things get ugly.
SPEAKER_01You see your friend get the promotion, you feel that exact same initial ache, but the brain processes it differently. Instead of motivation, it generates a desperate desire to pull the envied person down to your level.
SPEAKER_00This is where the rumors, the undermining, and the sudden withdrawal of cooperation originate.
SPEAKER_01Malicious envy doesn't pull the envier up. It seeks only to drag the envy down, which results in objectively worse outcomes for everyone involved.
SPEAKER_00It's a lose-lose scenario.
SPEAKER_01Right. And uh the best way I can visualize this clinical division is a backyard scenario.
SPEAKER_00Okay, let's hear it.
SPEAKER_01So benign envy is seeing your neighbor's incredibly beautiful blooming garden, feeling a pang of jealousy, and then going out to the store to buy better fertilizer for your own yard. You want your yard to meet their standard.
SPEAKER_00Right. You want to grow.
SPEAKER_01Exactly. But malicious envy is seeing that same beautiful garden waiting until it gets dark, sneaking over the fence and salting their soil so absolutely nothing grows.
SPEAKER_00Oh wow. That analogy perfectly captures the behavioral divergence. What's fascinating here is that the exact same triggering event, like the neighbor's beautiful garden or the trade friend's successful business, can trigger either form of envy.
SPEAKER_01It could go either way.
SPEAKER_00Exactly. The researchers found that the divergence relies entirely on the internal cognitive calculations the envyer makes to protect their own ego.
SPEAKER_01Okay, protect their ego how?
SPEAKER_00Well, it hinges on whether they view this success as deserved, whether they view the overarching system as fair, and crucially, whether the envyer sees a realistic path available to improve their own situation.
SPEAKER_01A realistic path. Okay, so if we look closely at the path, we can really see the mental gymnastics playing out. Think back to the competitor in the Oklahoma trade.
SPEAKER_00Right, the guy spreading rumors.
SPEAKER_01Yeah. He had been working in the industry just as long as the successful builder. He started around the same time. He's a decent, hardworking guy, but he simply hadn't built the same level of success, wealth, or reputation over those 20 years.
SPEAKER_00And somewhere along the way, looking at the gap between them, he experienced massive cognitive dissonance.
SPEAKER_01His brain couldn't handle the thought, we started at the same time, and he is simply better at this than I am.
SPEAKER_00Exactly. That's too painful. So to protect his ego, he internalized the gap as unjust. More importantly, he perceived his own path to reaching that level of success as permanently blocked.
SPEAKER_01The neighbor only salts your soil because they believe the hardware store is permanently sold out of fertilizer?
SPEAKER_00That's exactly it. If they feel entirely incapable of growing their own garden to match yours, the only way to alleviate that painful feeling of inferiority is to destroy your garden. So you both look equally barren.
SPEAKER_01Wow. So the malice, the rumors, the salting of the soil, these are merely symptoms of feeling trapped behind a blocked path.
SPEAKER_00Yes. When the success looks deserved and a path forward is visible, the brain processes it as benign envy. When the success threatens the ego and the path feels completely blocked, malicious envy takes over.
SPEAKER_01Which brings up a terrifying reality for anyone who is doing well. I mean, if malicious envy is dictated entirely by the envier's internal perception of a blocked path, what does that actually mean for the person on the receiving end?
SPEAKER_00It puts them in a very tough spot.
SPEAKER_01Right. Because for the builder in Oklahoma, or for you know the listener driving to work right now who just got promoted, our natural human instinct, especially for those of us who are people pleasers, is to try and fix a broken dynamic when a friend is mad at us.
SPEAKER_00Aaron Powell But the clinical reality shows why the instinct to fix it through diplomacy is doomed to fail.
SPEAKER_01Here's where it gets really interesting. Let's say I am extremely conflict averse. I value the friendship. I just want the rumors to stop.
SPEAKER_00A totally normal reaction.
SPEAKER_01Right. Simple math suggests that if the problem is the massive gap between our success levels, I can just close the gap from my end.
SPEAKER_00Wait, so you're telling me you could literally self-sabotage your own hard-earned business, actively shrink your operations, and make yourself look less successful to appease this guy, and it wouldn't work.
SPEAKER_01If we connect this to the bigger picture, the notes from Dave Hartzell highlight the tragedy of that exact impulse. The relationship is fundamentally breaking from the inside. Diplomacy won't work. Generosity won't work.
SPEAKER_00So the successful builder could suddenly lower his prices.
SPEAKER_01He could purposely slow down his cruise.
SPEAKER_00He could intentionally take fewer jobs to artificially shrink the gap.
SPEAKER_01And the malice still would not lift.
SPEAKER_00Why wouldn't it lift? I mean, if I take a massive hit to my own livelihood to close the gap, shouldn't the hostility end?
SPEAKER_01Because malicious envy does not respond to new rational information. The envier isn't reacting to the builder's real-world business practices or his current bank account.
SPEAKER_00They aren't.
SPEAKER_01No. They are reacting to a fictional story they have constructed in their own mind to excuse their failure.
SPEAKER_00Aaron Powell They've convinced themselves that the builder must be cheating or cutting corners or manipulating the market. The gap between them has become structural in the envier's mind. So changing your behavior as the envied person does absolutely nothing to rewrite the internal story they desperately need to believe.
SPEAKER_01You are basically held hostage by a fictional narrative playing out in someone else's head just to protect their fragile edo.
SPEAKER_00Exactly.
SPEAKER_01Knowing that you cannot shrink yourself enough to save the friendship, is there any intervention the envied person can actually deploy?
SPEAKER_00That brings us to the single intervention the Dutch research supports. And the painful reality of what happens when that intervention fails.
SPEAKER_01Right. According to Van De Ven's framework, there is only one indirect intervention that has a statistical chance of working.
SPEAKER_00You have to change the structural conditions that produce the malice. You have to make the path visible.
SPEAKER_01If malicious envy is caused by the envier feeling like the hardware store is out of fertilizer, the only way to diffuse the bomb is to literally show them where the fertilizer is kept. Show them the map.
SPEAKER_00You share specific, actionable information. You offer genuine mentorship. You are explicitly clear and transparent about exactly how you achieved your success, step by painful step.
SPEAKER_01And if the envyer can suddenly see a realistic, tangible way to close the gap through their own effort, the cognitive dissonance breaks.
SPEAKER_00Right. The brain no longer needs to destroy you to protect itself, and the malice can sometimes convert back into benign, upward-pulling envy.
SPEAKER_01Aaron Powell The heartbreaking part of the Oklahoma Builder story is that he actually tried this.
SPEAKER_00He did.
SPEAKER_01He offered small, gracious openings to his competitor. He tried to share specific strategies that were working for his business. He held out the map.
SPEAKER_00And the competitor flat out refused to take the openings.
SPEAKER_01He wouldn't look at the map because looking at the map requires admitting that the path was there all along and the failure was his own.
SPEAKER_00And when the envier refuses to see the path, the malice continues unabated. The fictional narrative is just too comforting to abandon, which forces the envied person into the final unavoidable resolution.
SPEAKER_01The builder had to let the relationship go entirely. And uh what struck me in Dave's notes is the manner in which he did it. He didn't blow up and create a massive dramatic scene.
SPEAKER_00Oh, no screaming matches.
SPEAKER_01He didn't launch a countersmear campaign either. He just quietly stopped treating the competitor as a friend. He told Dave that he grieved the friendship the way you grieve a friend who moved away. Wow. Even though the guy was still driving his work truck around the exact same central Oklahoma town.
SPEAKER_00It requires a profound psychological boundary. You mourn the loss of a connection that remains physically present but is, you know, emotionally dead.
SPEAKER_01It led to this incredibly bitter lesson for the builder. Here is a man in his fifties, realizing he spent his entire life and his entire career partly wanting to be liked. He worked tirelessly for the approval of his peers.
SPEAKER_00And he finally understood that doing the work exceptionally well inherently cost him the very approval he was seeking.
SPEAKER_01So what does this all mean? Dave wrote down a quote from the builder that just echoes in your head. He said, The thing nobody tells you is that being good at something is going to cost you some friendships you did not want to lose.
SPEAKER_00It's heavy. But as you grow and succeed, you have to recognize the pattern of malicious envy early. Once you see the soil salting begin, you have to stop trying to fix the dynamic through self-sabotage or extreme diplomacy.
SPEAKER_01You just can't.
SPEAKER_00No. You cannot diplomatize your way around someone else's cognitive dissonance. You have to start the necessary grieving process for a friendship that is functionally gone.
SPEAKER_01To wrap up this deep dive, we really want to speak directly to you listening. If you are doing well right now in any domain, your career, your hobbies, your personal growth, and you notice someone you used to genuinely like quietly turning hostile.
SPEAKER_00Remember Dave Hartzell's 45 Years of Wisdom from the Trade?
SPEAKER_01Right. And remember the Dutch psychology team's rigorous research. The malice you are experiencing is a symptom of their perceived blocked path and their need to protect their own ego.
SPEAKER_00It is not about your flaws.
SPEAKER_01It is not because you are doing something wrong by succeeding. You can try to show them the way, you can offer them the map, but if they refuse to look at it, your only job is to keep doing the work, keep tending to your beautiful garden, and gracefully let the relationship go.
SPEAKER_00This raises an important question if we scale the psychology outward, though. I mean, if malicious envy thrives in environments where the paths to success seem blocked or unfair, could we actually diagnose the overall health of an entire company or even a whole community?
SPEAKER_01Just by measuring the ratio of malicious to benign envy.
SPEAKER_00Exactly. Are the most notoriously toxic workplaces in the world actually just spaces where the employees are trapped, where absolutely no one can see a clear, visible path forward?
SPEAKER_01That is a phenomenal thought to leave on. It brings us right back to where we started. You cross that finish line, you achieve the great thing, and you brace yourself. You listen closely to the people around you, and now you know exactly why sometimes, instead of the applause you earned, you only hear the whispers.
