The framework you deploy on every scene has a name. Here’s what the research says about it.
When you roll up on a scene, you’re not just running a call. You’re performing a real-time trust assessment. Dr. Cory Scheer has spent years researching organizational trust across industries. His finding: the structure that makes trust work is universal. And it maps exactly onto what experienced EMS providers do intuitively from the moment they step out of the rig.
This post breaks down Scheer’s framework, applies it to the prehospital environment, and gives field trainers and crew leaders a practical language for something most providers already do but have never named.
The Three Building Blocks
Scheer’s research identifies three evidence-based components that create trust in any context:
1. Competency
Competency is more than technical skill. It includes communication ability, risk management, time management, and leadership. A provider who can intubate flawlessly but can’t give a coherent radio report is demonstrating partial competency — and patients and teams pick that up immediately. Trust radars are sensitive. People sense competency gaps before they can articulate them.
2. Problem-Solving
This is the preflective dimension of what you do: anticipating failure, preventing secondary harm, triangulating data. Scheer compared it to mountaineering navigation: you’re getting three waypoints to triangulate position before you move. In EMS, that looks like scanning for mechanism, gathering history, and mentally simulating what comes next.
3. Care for Others
This is where EMS providers most often think they can cut corners and it’s where Scheer’s research is clearest: you can’t. Active listening is the single most research-backed behavior for demonstrating care. This goes beyond just nodding along while you complete another task. Actual listening: making eye contact, asking follow-up questions, looping back to confirm what you heard. The patient who feels seen cooperates becomes apart of your team to care for them. Where as the patient who feels like they’re just being mechanically processed, shuts down, withholds history, or escalates.
Your Trust Signature
Every person leads naturally with one of the three building blocks. Scheer calls this your trust signature.
Will’s natural lead is competency (or if you ask Ross it’s actually care for others). Ross’ is problem-solving. Scheer’s is problem-solving. His wife’s is care for others.
Knowing your signature matters because the building block you lead with is also the one you over-rely on. The medic who is purely competency-focused can technically treat every patient but will escalate the ones who need to feel cared for before they’ll let you touch them. The provider who leads with care may earn immediate patient trust but miss clinical data because they’re too busy being empathetic to look for it.
The fix isn’t to abandon your natural lead. It’s to bring the other two to the table deliberately.
Scene Arrival as a Trust Assessment
Scheer asked Will to walk him through his scene size-up. Will’s answer: Is this safe? What happened? Who is the patient, and how do I build rapport fast?
Scheer’s response: that sequence is the structure of trust. Safety = competency and risk management. What happened = problem-solving. Building rapport = care for others.
The same three-part assessment that gets you from the rig door to a working diagnosis is the same process Scheer uses to diagnose organizational trust deficits in Fortune 500 companies.
The practical implication is that you already have the framework. The question is whether you’re deploying it deliberately on every patient, including the ones who are angry, or intoxicated, or have just committed a crime.
The Leadership Gap in EMS
Scheer’s national research found a 31% gap between how senior leaders perceive trust in their organizations and how frontline employees experience it. Senior leaders consistently believe things are better than they are. Frontline workers believe things are worse than they are. And the mid-level supervisor, the lieutenant, the operations coordinator, is caught in the middle, being pulled in both directions simultaneously.
This is not unique to EMS, but EMS amplifies it. Frontline providers spend the majority of their shift without any contact with leadership. When contact does occur, it tends to be about compliance, complaints, or crisis, which means the data senior leaders receive about frontline trust is systematically skewed negative, and the data frontline providers receive about leadership is rare and often disciplinary.
Scheer’s solution is to treat mid-level managers as the critical culture bridge. They’re the ones who can translate senior-level truth to the floor and frontline experience back up the chain. If you’re in that role, your job is not just operations. You’re a translator.
Self-Trust and Imposter Syndrome
Scheer describes seven layers of trust: transactional, interpersonal, structural, organizational, relational, emotional, and self-trust. Self-trust is the innermost layer and the one most leaders underinvest in.
Imposter syndrome is a signal from that layer. Scheer reframes it like this: Don’t camp out with the signal. Ask what it’s telling you. What specific work do you feel you haven’t done? What value or competency is this pointing at?
For EMS providers, that might look like: you’ve been avoiding airway management because it makes you anxious. The imposter feeling is not purely irrational. And we should not just white-knuckle through the feeling while hoping nobody notices. Instead lean into it because the real work is to name the specific gap it’s pointing to and close it.
Self-trust is also foundational to team trust. If you don’t trust yourself, you won’t ask for help. And if you won’t ask for help, you’ll make calls alone that should have been made with your partner, your medical director, or your supervisor.
The Headwaters Principle
Trust is upstream. Loyalty is downstream.
Organizations obsess over satisfaction surveys, retention metrics, and employee loyalty data — all of which are lagging indicators. By the time those numbers move, the cultural damage is already done. The headwaters of culture are the daily interactions: how a supervisor handles a difficult feedback conversation, whether a partner feels heard after a hard call, whether a new medic gets accurate information about what to expect in their first year.
When those headwaters are healthy, everything downstream benefits. When they’re poisoned, no downstream intervention fixes it without going back to the source.
Key Takeaways:
- Trust has a structure: competency, problem-solving, and care for others. All three are required.
- You have a trust signature, a natural lead. Know which building block you over-rely on and build the others deliberately.
- There’s a real gap between leaders at the top and frontline providers. Mid-level EMS supervisors are the culture bridge. That role is harder than it looks.
- Imposter syndrome is a signal. Get specific about what it’s pointing at and do the work.
- Culture lives in the headwaters. Loyalty and retention are downstream results. Fix the upstream.
