How should an ethicist reason under deep factual uncertainty? Is there an ethics of withholding judgement, and when does withholding become complicity?
The facts at the centre of the case behind these seminars are deeply uncertain. The district attorney and the complainant’s lawyer have given incompatible accounts of what her signed statement showed. The university reached findings under a standard of proof lower than that of a criminal court, and its reasoning is not public. The criminal case has been reopened, a civil suit is pending, and an independent investigation has been commissioned. Anyone reasoning ethically about the case must do so without knowing what happened. That raises a question about the ethics of belief itself: when should we suspend judgement, and when does suspending judgement become a way of taking sides?
The ethics of belief
In a famous essay of 1877, the mathematician W. K. Clifford argued that “it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.” His example was a shipowner who sent an unseaworthy ship to sea after persuading himself, without evidence, that it was safe. Clifford’s point was that belief is not a private matter: beliefs guide action, shape the beliefs of others and can cause harm. William James replied that in some cases, where the choice is live, forced and momentous, we may be entitled to believe without conclusive evidence, because refusing to choose is itself a choice.
Both insights apply here. Clifford warns against the confident public verdicts that circulated quickly after the accused were named, including the misidentification of an uninvolved man. James warns that refusing to form any view can itself have consequences, especially for people who need others to take a stand.
Tools for reasoning under uncertainty
Several approaches help an ethicist proceed without pretending to knowledge they lack.
Graded belief. Belief need not be all or nothing. One can hold that something is more or less likely, and update as evidence arrives. Much public discussion collapses into binary positions: guilty or innocent, lying or truthful. A graded view allows one to take an allegation seriously without treating it as proven.
Conditional judgement. Many ethical conclusions can be stated conditionally: if the complainant’s account is accurate, then certain people did serious wrong and certain institutions failed her; if the original decision not to charge rested on a misreading of her statement, then that decision was unjust. Conditional reasoning allows ethical analysis to proceed while being honest about its dependence on facts.
Robust conclusions. Some conclusions hold across all plausible versions of the facts. Whatever happened, publicising the wrong person’s name was a serious harm. Whatever happened, a group of around fifty people reportedly received information that night and no one called the police, and that raises questions about the culture of that group. Whatever happened, the complainant is entitled to a competent and impartial investigation, and the accused are entitled not to be punished without proper process. Identifying robust conclusions lets us say a good deal without resolving the disputed facts.
Separating belief from action. Many decisions do not require certainty about the central facts. A university can provide support to a complainant without deciding that her account is true. A citizen can call for a proper investigation without deciding the outcome. Policies about bystander intervention or institutional transparency can be justified on general grounds. Uncertainty about one question does not paralyse action on others.
When does withholding become complicity?
Withholding judgement is a virtue when it reflects genuine uncertainty, respect for process and awareness of the harm that confident error can cause. But it can become something else. Several warning signs are worth naming.
When uncertainty is used to avoid inquiry. Withholding judgement is legitimate when the facts cannot be known. It is not legitimate when it is used as a reason not to find them out. Philosophers and lawyers have discussed wilful blindness, where a person deliberately avoids knowledge that would require them to act. An institution that says it cannot comment because the facts are uncertain, while failing to take steps to establish them, is not exercising epistemic humility.
When withholding spreads beyond what is uncertain. Uncertainty about whether an assault occurred does not imply uncertainty about everything. One can withhold judgement on the central allegation while forming clear views about institutional processes, the treatment of the complainant, or the conduct of the press. Using uncertainty about one question as a reason for silence about all of them is a kind of evasion.
When withholding is asymmetric. Suspension of judgement should apply evenly. If one suspends judgement about the complainant’s account while accepting the accused’s denial, or vice versa, one is not withholding judgement but taking a side while appearing neutral. Miranda Fricker’s work on testimonial injustice describes how listeners can deflate a speaker’s credibility because of prejudice. Selective scepticism, in either direction, can be a form of injustice.
When one has a role responsibility to decide. Jurors, hearing panels and prosecutors cannot withhold judgement indefinitely. Their role requires them to decide on the evidence, however imperfect. For them, refusing to judge is itself a decision with consequences.
When the person harmed needs a response. Suspending judgement about facts does not justify withholding care, support or acknowledgement of someone’s experience. A friend who says “I cannot know what happened, so I will say nothing” to someone who has disclosed an assault may be epistemically cautious but is failing in another duty.
Conclusion
An ethicist reasoning under deep factual uncertainty should be precise about what is unknown, draw conditional and robust conclusions, separate belief from action, and resist the pressure to collapse uncertainty into a verdict. There is a genuine ethics of withholding judgement, grounded in respect for truth and awareness of the harm of error. But withholding becomes complicity when it is used to avoid inquiry, extended to questions that are not uncertain, applied selectively, abandoned by those whose role requires judgement, or used as a reason to deny support. Epistemic humility is a virtue only when it is honest about what it is humble about.
