I have a great deal of respect for Yogi Sharp, and this post really resonated with me.
My interpretation of his central message is that we cannot judge the success or failure of any hoof-care intervention while ignoring the population and the context in which it is being used.
Every horse exists within a complex combination of variables: breed, genetics, conformation, hoof morphology, pathology, diet, environment, climate, movement, workload, surface and management. These variables do not act independently—they interact.
A method that appears highly successful within one particular group of horses cannot automatically be treated as a universal biological rule. Equally, the absence of a pathology in one practitioner’s population does not prove that their intervention prevented it, just as its presence in another population does not automatically prove that the intervention caused it.
The important question is not simply, “Which method or material is right?”
It is: “For this individual horse, living in these conditions and being asked to perform this job, what intervention is most likely to achieve the biomechanical outcome we need?”
This is why we must look beyond methods and materials and consider the whole horse, the environment and all the variables that may be influencing the outcome.
As Yogi says, we cannot argue about materials until we have achieved biomechanical function—and we should never mistake the limits of our own experience for the limits of biological reality.
An excellent and thought-provoking post from Yogi Sharp, which I am very pleased to share.
Do we have a problem with population and context blindness in the hoof care industry?
Something has come up repeatedly in conversations with delegates during the clinics here in America, and I think it highlights a much bigger problem within hoof care education.
A few people have mentioned things they have heard about what I supposedly teach.
And sometimes I barely recognise my own teachings in the description.
Usually, somebody has taken one concept I have discussed, removed it from the wider framework in which it was presented, and turned it into a rule.
“Yogi says you should do X.”
“Yogi believes Y is always wrong.”
But that is almost the opposite of what I am trying to teach. Because before I am a teacher of any particular hoof-care intervention, I am a scientist. And science teaches us something incredibly important.
Populations matter.
When we conduct research, we do not simply observe an outcome and declare it universally true.
We define the population.
What horses were studied?
What breed were they?
What age?
What environment were they living in?
What surfaces were they standing and working on?
What pathology was present?
What management system were they kept under?
What intervention was being tested?
What variables were controlled, and which ones weren’t?
Only then can we begin to discuss what the findings actually mean.
Yet in hoof care, we often seem to forget this.
Someone develops a successful protocol within the population of horses they see every day. It works extremely well. Naturally, they become convinced by it.
The problem begins when success within a population becomes presented as a universal biological rule.
I have travelled enough now to realise just how dangerous that assumption can be.
The horses I see in one part of England are not living the same biological and mechanical reality as horses in Florida, Georgia, California, Scandinavia, Australia or the Middle East.
Even within the same country, populations can be dramatically different.
Think about the variables.
Hydration of the hoof capsule.
Environmental humidity.
Temperature.
Seasonality.
Diet and nutritional status.
Breed and genetics.
Body mass.
Conformation.
Hoof morphology.
Existing pathology.
Previous pathology.
Growth rate.
Movement allowance.
Turnout.
Stabling.
Workload.
Discipline.
Speed.
Surface firmness.
Surface depth.
Surface abrasiveness.
Traction requirements.
Distance travelled each day.
Human expectations of performance.
And importantly, all of those variables interact.
That is why I can simultaneously believe that barefoot represents an incredibly useful biological reference point, while also recognising that barefoot is not necessarily the appropriate intervention for every horse in every environment performing every job.
Steel has advantages.
Steel also has disadvantages.
Composite materials solve some problems and introduce others.
Different shoeing systems alter mechanics in different ways.
Different trimming approaches may produce different outcomes depending on the morphology they are applied to.
The interesting question is therefore rarely
“Which one is right?”
The better question is
“Under what conditions does this intervention produce the outcome we want?”
That distinction matters enormously.
Because another phenomenon follows from population blindness.
Someone works predominantly with a particular population of horses and rarely encounters pathology X.
They then look at another practitioner working with a completely different population who sees pathology X regularly and conclude:
“You see that pathology because of the way you manage the hoof. I don’t see it because I don’t do what you do.”
Maybe.
That hypothesis deserves investigation.
But there is another possibility that should be considered before making the accusation
You are looking at different populations.
Different genetics. Different environments. Different workloads. Different surfaces. Different management. Different movement opportunities. Different nutritional inputs. Different performance expectations.
Absence of a problem within your population does not automatically prove that your intervention prevented it.
And presence of a problem within somebody else’s population does not automatically prove that their intervention caused it.
That is basic scientific reasoning.
This is also why individual concepts from my lectures can become misleading when separated from the rest of the framework.
I talk about forces.
I talk about equilibrium.
I talk about hoof morphology.
I talk about spatial balance.
I talk about internal anatomy.
I talk about materials.
I talk about barefoot function.
I talk about shoes.
I talk about posture, movement, environment, pathology and management.
None of those things exists independently.
The point isn’t to give people another protocol to blindly follow.
The point is to give people enough understanding of the system that they can reason their way through the horse standing in front of them.
That, to me, is the difference between teaching a method and teaching a framework.
A method says
“Do this.”
A framework asks
“What variables exist here, what effect are they having on the system, and therefore what intervention makes sense?”
The more of the world I see, the less interested I become in universal hoof-care rules.
Not because biology has no rules.
Quite the opposite.
The underlying physics, anatomy and biology give us the rules.
But the expression of those rules occurs within enormously variable biological systems and enormously variable environments.
Our job is to understand both.
Perhaps one of the most important things we can teach, therefore, is intellectual humility.
Your experience matters.
Your results matter.
Your population matters.
But the world is much bigger than the population of horses any one of us happens to see.
We should be very careful not to mistake the boundaries of our own experience for the boundaries of biological reality.
This is a similar concept to my
“You can’t argue materials until you have achieved biomechanical function”
