For generations, progress has meant making life safer. We developed safer automobiles, safer workplaces, safer playgrounds, safer medicines, safer food, safer buildings and stronger protections against crime, disease and discrimination. Few would seriously argue that we should abandon those achievements. But there is another question we ask far less often: can a society become too safe?

More precisely, can our determination to protect ourselves from every conceivable danger eventually begin to diminish something equally important—our independence, privacy, personal responsibility, resilience and ultimately our liberty? The issue is not protection. Protection is one of the essential responsibilities of civilized society. The issue is over-protection.

Claim One: If something makes us safer, more of it must make us better off. — FICTION.

Safety is valuable, but it is not the only thing we value. We could theoretically eliminate many automobile deaths by prohibiting private automobiles. We could reduce playground injuries by removing climbing equipment. We could reduce financial fraud by monitoring every financial transaction. We could make some public places more secure by continuously identifying and tracking everyone who enters them. Each of these measures might reduce a particular risk, but few of us would regard the resulting society as necessarily better.

This reveals the central problem with over-protection. Safety has benefits, but protection can also have costs. Those costs may be financial or inconvenient, but more importantly they can include privacy, autonomy, experimentation, personal judgment and freedom. The appropriate question is therefore not simply, Does this make us safer? It is: How much safer does it make us, what must we surrender in exchange, and is the trade worthwhile?

Claim Two: Eliminating risk is particularly good for children. — FICTION.

Perhaps nowhere is the paradox of over-protection clearer than in childhood. Parents quite naturally want to protect their children, yet children also develop by encountering uncertainty, making judgments, occasionally failing and learning what they are capable of doing.

The Canadian Paediatric Society distinguishes between hazards, which children may be unable to recognize or manage, and risks, which can provide opportunities for learning and development. Its guidance argues that developmentally appropriate risky play can contribute to physical activity, confidence, emotional regulation, cognition and social development. Its wonderfully simple principle is that children should be kept “as safe as necessary” rather than “as safe as possible.”

The distinction is important. A broken playground railing is a hazard and should be repaired. Climbing the properly maintained playground structure is a risk. If we remove every hazard, we make children safer. If we attempt to remove every risk, we may also remove opportunities for children to develop judgment, confidence and independence. A scraped knee occasionally teaches something that a warning cannot.

Claim Three: Governments sometimes have legitimate reasons to restrict liberty in the interest of public safety. — FACT.

Freedom has never meant the absolute right to do anything one chooses. Societies prohibit impaired driving, establish building codes, regulate dangerous products, enforce speed limits and restrict conduct that creates unreasonable risks for others. These are legitimate functions of government.

Canadian constitutional law recognizes this reality. Section 1 of the Canadian Charter of Rights and Freedoms guarantees rights and freedoms while permitting limits that can be demonstrably justified in a free and democratic society. Canadian courts consequently ask whether an objective is sufficiently important and whether the restriction imposed is proportionate to that objective, including whether the measure impairs a right no more than reasonably necessary.

That principle is useful far beyond constitutional law. Protection must be proportionate to the danger. The existence of a risk does not, by itself, justify every measure capable of reducing it.

Claim Four: New technology is making over-protection easier. — FACT.

This may be where the issue becomes particularly important. For most of history, extensive surveillance was difficult and expensive because watching someone required another person to do the watching. That is no longer true.

Cameras, smartphones, facial recognition, financial records, location data, connected vehicles and enormous digital databases can make it technically possible to observe, identify and reconstruct human behaviour on an unprecedented scale. Much of this technology has legitimate uses. It can locate missing people, identify criminals, prevent fraud and improve public security. But technological capability presents us with a dangerous temptation: because we can monitor something does not necessarily mean that we should.

The same principle of proportionality applies. Surveillance should not be judged simply by whether it can improve security. We must also ask whether it is necessary, whether it is effective, what information is collected, who controls it, how long it is retained and what protections exist against misuse.

Claim Five: Over-protection can gradually diminish liberty without anyone consciously deciding to abolish it. — FACT IN PRINCIPLE.

This may be the most important point. Free societies rarely wake up one morning and deliberately decide that freedom is no longer desirable. Restrictions usually arrive individually and for understandable reasons: one more camera, one more identification requirement, one more regulation, one more prohibited activity, one more database, one more precaution and one more rule intended to make somebody safer.

Any individual measure may be completely reasonable. The danger arises when each is considered separately without periodically examining their cumulative effect. Liberty can be diminished incrementally, not because anyone intended to abolish it, but because every small surrender seemed reasonable at the time.

That is why the question should never simply be whether a proposed protection has a worthy objective. Most do. We should also ask whether the danger is real, whether the proposed measure materially reduces it, whether a less intrusive alternative exists, what freedoms or privacy are being surrendered, who decides, who provides oversight and, ultimately, when protection becomes over-protection.

The Resilience Paradox.  There is another consequence worth considering. Human resilience develops partly through encountering difficulty. We learn judgment by making judgments, acquire confidence by discovering that we can manage uncertainty, learn responsibility by being given responsibility, and learn to recover from failure by occasionally being permitted to fail.

A society determined to remove every uncertainty may therefore inadvertently weaken some of the capacities people need when genuine adversity arrives. The objective should not be to expose people unnecessarily to danger. It should be to distinguish between danger that should be prevented and risk that teaches us how to live. That distinction begins on the playground, but it does not end there.

The Verdict: FACT — Over-Protection Is a Real Risk.

The great improvements in public safety achieved over the past century should be celebrated, not reversed. Seat belts save lives. Building codes prevent disasters. Public-health measures control disease. Consumer protections reduce exploitation. Police protect communities. Governments have legitimate responsibilities to protect their citizens.

But protection should never become an unquestioned good for which there is no upper limit. There must always be another value on the other side of the scale: liberty.

Perhaps the Canadian constitutional principle offers the right civic standard. Protection should be necessary, effective and proportionate, while impairing freedom no more than reasonably required. Or we could borrow the wonderfully practical language now being applied to children’s play: a healthy society should strive to make its citizens as safe as necessary—not as safe as possible.

A society that attempts to protect people from every conceivable risk may eventually discover that it has begun protecting them from something else: the freedom to live their own lives.
