Why Aversive Methods Change What We See, Not What’s Really Going On

I’ve been thinking a lot about aversive behaviour change methods recently — not just in dog training, but in how we try to change behaviour more generally.

There’s a simple analogy that keeps coming back to me.

Imagine someone bites their nails.
Not because they enjoy it, but because they’re anxious, overstimulated, bored or trying to regulate themselves.

Now imagine trying to stop that habit by punching them in the arm every time they bite their nails.

It sounds ridiculous, even cruel. But it’s also strangely effective — at least on the surface.

They might stop biting their nails.
Or more accurately, they might stop biting their nails around you.

But nothing has changed underneath.

Suppression isn’t the same as resolution

The nail biting didn’t come from nowhere.
It served a purpose.

By adding pain or discomfort, you haven’t removed the need — you’ve just made expressing it unsafe.

Over time, a few predictable things happen:

The person becomes tense around you
They hide the behaviour
They find another outlet (skin picking, jaw clenching, pacing)
Or they simply tolerate the punishment

And when tolerance sets in, escalation follows.

You punch harder.
Or faster.
Or more often.

The original problem is still there, just buried under avoidance.

This is how many aversive methods work

The same pattern shows up with many aversive approaches to behaviour change.

In dog training, that might look like:

prong or choke collars
shock or vibration collars
leash corrections
yelling or startle techniques
“firm handling” or physical manipulation
even subtler forms of pressure or intimidation

These methods are often praised because they produce quick, visible compliance.

The dog stops pulling.
Stops barking.
Stops reacting.

From the outside, it looks like success.

What we don’t always see

What we don’t always see is what’s happening internally.

Many behaviours are driven by:

fear
frustration
overwhelm
lack of coping skills
unmet needs

Adding discomfort doesn’t resolve any of that.
It just changes what’s safe to express.

So instead of pulling or barking, you might see:

shutdown
hyper-vigilance
avoidance
loss of behavioural flexibility
or reactions that seem to come “out of the blue” later

Calm becomes confused with coping.

Why aversive methods are so tempting

Aversive tools appeal to us because they:

work quickly
restore a sense of control
reduce embarrassment in public
make us feel safer

They solve human discomfort very efficiently.

But they rarely solve the underlying behavioural problem.

What real behaviour change tends to look like

Lasting change usually happens when the need for the behaviour disappears, not when the cost of expressing it becomes too high.

That means:

addressing emotional drivers
teaching alternative skills
reducing overwhelm
increasing predictability and safety
reinforcing behaviours we want to see instead

This kind of work is quieter.
Slower.
Less dramatic.

But it generalises better and holds up under pressure.

Same outcome, very different mechanisms

From a distance, suppression and resolution can look identical.

The behaviour stops either way.

But one relies on fear and avoidance.
The other relies on understanding and regulation.

And the difference usually shows up later — in resilience, trust and how well the individual copes when things get difficult.

Suppressing behaviour and resolving it aren’t the same thing.

They just look similar if you’re only watching the surface.
