Critical thinking: Applying judgement in an age of instant answers

AI can produce an answer in seconds. It can summarise documents, identify themes, generate arguments and present information in a polished and convincing form. This creates significant opportunities for legal professionals. It also introduces a risk: the temptation to accept an answer before properly evaluating it.

The easier information becomes to generate, the more important critical thinking becomes.

Plausible is not the same as correct

AI-generated content can appear authoritative even when it is incomplete, inaccurate or based on an incorrect assumption. Critical thinkers do not assess an answer solely on how convincing it sounds. They examine the reasoning behind it.

They ask:

• What evidence supports this conclusion?
• Is the source reliable and current?
• What assumptions have been made?
• What relevant information may be missing?
• Is there another interpretation?
• Does the conclusion follow logically from the evidence?
• What would happen if this answer were wrong?

These questions have always mattered in legal practice. The growing use of AI makes them essential at every level.

Defining the real problem

Critical thinking begins before the search for an answer. A poorly defined problem can lead to an irrelevant response, however sophisticated the tool used to explore it. Lawyers therefore need to understand what is actually being asked, why it matters and what constraints affect the possible solution.

A client may present a legal question when the underlying issue is commercial, operational or relational. Answering only the question as framed may fail to address what the client really needs. Thoughtful professionals take time to clarify the objective before moving to analysis.

Separating fact from interpretation

Complex decisions often involve a mixture of facts, assumptions and opinions. Problems arise when these categories are treated as though they are the same.

For example:

• “The team has not adopted the new system” may be a fact.
• “They are resistant to change” is an interpretation.
• “They need firmer management” is a proposed response.

Critical thinking involves recognising the difference. Alternative explanations may exist. The system may be difficult to use, expectations may be unclear or people may not have received sufficient training.

The quality of the decision depends on whether the underlying assumptions have been tested.

Challenging familiar ways of working

Assumptions are not limited to new technology. A team may continue using a process because it has always been done that way. A leader may assume that the most senior person should make every decision. A lawyer may believe that the client always wants the lowest-risk option.

Critical thinking brings these assumptions into view. It asks whether an established approach is still serving its purpose and whether a different method might produce a better result. This does not mean challenging everything for the sake of it. It means being willing to examine the reasoning behind familiar practices.

Judgement when information is incomplete

Legal professionals frequently make decisions without having every piece of information they would ideally like. Critical thinking does not remove uncertainty. It helps people navigate it. Good judgement involves weighing the available evidence, recognising limitations and explaining the basis for the chosen approach. It may also involve identifying what information would materially change the decision and what can safely remain unknown.

AI can provide analysis and possible options. Responsibility for the final judgement remains with the professional using it.

Creating space for thoughtful challenge

Firms benefit when people can question conclusions without being regarded as difficult. Junior colleagues may identify an inconsistency that a senior person has overlooked. Business services professionals may bring a perspective that changes how a legal issue is understood.

Leaders who invite thoughtful challenge strengthen decision-making and reduce the risk of groupthink. As instant answers become normal, professional value will increasingly lie in knowing which answers to question, what evidence to trust and when further investigation is required.

Critical thinking enables technology to be used intelligently rather than unquestioningly.
