Scientists have explained why ignorance is sometimes scarier than the worst truth

People aren't always eager to learn the truth - but they're not always willing to hide from it, either. A new study by researchers at Tel Aviv University offers an unexpected explanation for why we consciously avoid information in some situations and seek out even painful and frightening information in others.

The work was conducted by Professor Yaniv Shani of Tel Aviv University's Koller School of Management and Professor Marcel Seelenberg of the Tilburg School of Social and Behavioural Sciences. The study is published in the journal Current Opinion in Psychology.

Not an escape from responsibility, but a defence of the psyche

Contrary to popular belief, so-called "wilful ignorance" is far from always linked to a desire to avoid moral responsibility to others. According to the authors, much more often the refusal of information is a way of emotional self-regulation and defence against psychological overload.

Many people postpone receiving important information for fear of its emotional consequences. For example, they don't check medical tests before going on holiday or try not to look at their investment portfolio during a market crisis. This behaviour is not indifference - on the contrary, it is an attempt to delay a painful confrontation with reality.

Why we consciously look for bad news

However, the research also revealed an opposite strategy that serves the same purpose - managing emotions. In the face of uncertainty, people often purposefully seek out painful information, even if it has no practical benefit.

For example, consumers often check the prices of goods they have already bought, wanting to know whether they have overpaid, even though it is no longer possible to change the decision. In such cases, knowledge, however unpleasant, is less distressing than the unknown.

According to the authors, this phenomenon was particularly pronounced after the 7 October attack in Israel, when many families sought to know the fate of their loved ones despite the risk of receiving devastating news. For them, the uncertainty proved more painful than the hardest truth.

Two pains - one psychological mechanism

The authors analysed a wide array of scientific publications and compared them with their own experimental data. As a result, they proposed a simple model based on two key questions:

whether a person can tolerate uncertainty and whether they can tolerate the truth.

It turned out that both information avoidance and the active search for unpleasant information have a common source - an attempt to balance the fear of knowing and the suffering from the unknown. Depending on the situation, a person chooses the option that seems less painful.

Moral choice and the cost of ignorance

The researchers emphasise: this mechanism works not only in personal or everyday situations, but also in moral dilemmas. Sometimes people choose to "not know" how their actions affect others in order to avoid guilt. However, in cases where ignorance can cause serious harm, it is the inability to bear uncertainty that leads them to seek the truth.

According to the authors, in a world oversaturated with information, the desire to know and the desire not to know are not opposites, but two tools of psychological adaptation.

Why this is important for society

The findings have implications for health systems, government agencies and organisations. It is not only about what information people receive, but also how and at what point it is communicated to them.

The research shows that when making decisions, people are constantly weighing up whether truth or uncertainty will cause less pain. And in an age where information is always at our fingertips, the emotional cost of knowledge becomes as important as the facts themselves.
