Evaluate whether scientific and technological progress should be ethically constrained, weighing the drive to advance against moral limits

What this dot point is asking

This theme prepares you for General Paper questions on the ethics of progress: whether scientific and technological advance should be ethically constrained, captured in the slogan "just because we can does not mean we should". The central insight is that technical capability is not the same as moral permission, so progress should be ethically guided, but over-restraint that blocks beneficial advances is also a mistake, so the question is principled limits rather than stopping progress. A strong answer weighs the drive to advance against moral limits using frameworks such as the precautionary principle, and judges for guided progress.

The answer

Why "can" does not imply "should"

The core argument is a distinction between two kinds of question:

• Capability asks what is technically possible.
• Value asks whether we ought to do it.

These are different. Some advances, certain weapons, unethical experiments, some uses of gene editing or surveillance, cause serious or irreversible harm, so the fact that we can do them settles nothing about whether we should. Ethics is the discipline that judges whether to proceed, which is why "can" does not imply "should".

The risk of over-restraint

Balance requires recognising the opposite error. Excessive caution can forgo cures, growth and solutions to real problems; many fears about new technology have proved overblown; and progress has driven enormous gains in health, prosperity and knowledge. A blanket precaution that blocks anything new is as flawed as reckless advance. So the goal is principled limits, not halting progress.

The frameworks for deciding

Two tools structure a strong answer:

• The precautionary principle. Where potential harms are serious and irreversible, caution is warranted even under uncertainty. But it must be weighed against the cost of inaction, the benefits and lives a delayed advance forgoes.
• Who decides. Should limits be set by scientists, governments, the public, or all three? As with science funding, the defensible answer is a layered process combining expert judgement on risk with democratic accountability on values.

Ethics lagging behind technology

A deeper, sophisticated point: ethics and regulation often lag behind technological capability, because technology advances faster than laws and norms can deliberate, and commercial incentives push deployment ahead of reflection. This lag is dangerous where harms are serious and irreversible. But it is not inevitable: societies can build anticipatory ethics, fund foresight, involve ethicists early and adapt rules iteratively, and history shows ethics eventually catching up, as with medical ethics and data protection. The realistic goal is to narrow the gap between capability and ethical guidance, not to expect them to move in perfect step.

Examples in context

Example 1. Heritable gene editing and the precautionary principle. The prospect of editing human embryos in heritable ways illustrates "can does not mean should": it is increasingly technically possible, yet the harms, irreversible effects passed to future generations who cannot consent, are exactly the serious, irreversible kind the precautionary principle targets. It evidences the argument for ethical constraint on some advances, and contrasts with clearly beneficial uses such as treating disease, showing why ethics must judge case by case rather than letting capability decide.

Example 2. Ethics lagging behind artificial intelligence. The rapid deployment of powerful AI tools, ahead of settled rules on bias, accountability, misinformation and labour, exemplifies ethics and regulation trailing technological capability, driven partly by commercial incentives to deploy fast. It evidences the ethics-lag argument and the danger of the gap, while also pointing to the response: building anticipatory ethics and adaptive regulation to narrow the lag, which supports the judgement that the gap between capability and guidance is a manageable challenge rather than an inevitability to accept.

Try this

Q1. Explain the difference between asking what we "can" do and what we "should" do. [2 marks]

• Cue. "Can" is a question of technical capability, what is possible; "should" is a question of value and ethics, whether it is right to do it, and the two are distinct because possibility settles nothing about permission.

Q2. State the precautionary principle and one limit on it. [2 marks]

• Cue. The precautionary principle says we should act with caution where potential harms are serious and irreversible, even under uncertainty; its limit is the cost of inaction, since excessive caution can forgo real benefits and cures.

Q3. Explain why ethics often lags behind technological change, and why this matters. [3 marks]

• Cue. Technology advances faster than laws, norms and institutions can deliberate, and commercial incentives push deployment ahead of reflection, so society confronts novel capabilities before settling the ethics; this matters because where harms are serious and irreversible, acting before ethical guidance is in place is dangerous.
