The Cassandra Effect: Why Don't We Believe People Who Are Right?.

In Greek mythology, Cassandra was given an unusual gift and an even more unusual curse. She could see the future, but no one believed her. She warned the Trojans about what would happen, including the danger of the Trojan horse, but her warnings went unheeded. Her tragedy, then, was not that she did not know what was coming, but that she knew, spoke up, and was ignored.

Several thousand years later, we no longer believe in prophecies, but Cassandra's problem has not disappeared. Our organizations are full of Cassandras.

These are the people who spend months warning that a project will not end well, that a key employee will leave, that a particular process no longer works, that customers are becoming dissatisfied… Sometimes they are wrong, of course, but sometimes they see very clearly what the rest of the organization will only realize several months later.

The Problem Is Not Just the Information

We like to imagine organizational decision-making as a relatively rational process. We gather information, analyze it, assess the alternatives, and make the best decision. When new information emerges showing that something is wrong, a rational decision-maker should revise their view. The problem is that people generally do not work quite that way.

Information that tells us everything is fine is not psychologically equivalent to information that requires us to admit we might be wrong. The latter can threaten a previous decision, our status, our relationship with a superior, our perception of our own competence, or simply the comforting feeling that we have things under control.

So the problem is not just what someone says, but also what accepting that information means for the listener.

If an employee says a project is behind schedule, that is information. If accepting that information means the director has to admit to having made the wrong decision three months earlier, the same information suddenly carries an entirely different psychological cost. Unsurprisingly, it is much easier to conclude that the employee is exaggerating.

We Do Not Just Evaluate the Message. We Evaluate the Messenger, Too.

This is where the Cassandra effect becomes particularly interesting, because people rarely evaluate information entirely independently of the person presenting it. Status, reputation, position in the hierarchy, communication style, and prior relationships all influence how credible we consider a claim to be.

In organizations, this can lead to serious mistakes. Information from a high-status person may carry more weight than it objectively deserves, while the same information from an expert lower down the hierarchy may be played down or completely disregarded. And a particularly unpleasant place in hell is reserved for those who frequently bring unwelcome news.

If someone repeatedly warns of problems, they can very easily stop being seen as a person who identifies problems and become a “negative person.” The organization then stops evaluating the substance of their claims and starts judging their character instead. They are “always making things complicated,” “never satisfied,” or “seeing a problem in everything.”

We have thus performed a very elegant psychological maneuver: instead of assessing whether the warning is accurate, we have judged the person raising it. And the problem is solved, at least until the very thing they warned about actually happens.

Organizations Especially Love Good News

There is also a very simple behavioral explanation for this. The bearer of good news often produces pleasant “consequences.” They confirm that the strategy is sound, that the project is progressing, and that previous decisions were correct. The bearer of bad news does exactly the opposite. They create discomfort, require additional work, open up the possibility of conflict, and sometimes call for a decision already made to be changed.

If this dynamic repeats itself for long enough, the organization begins to view information selectively. There does not have to be any formal ban on discussing problems. It is enough for people to see a few times what happens to those who raise them.

If warnings are followed by uncomfortable questions, defensive reactions, marginalization, or a reputation as a “difficult person,” employees quickly learn something important: perhaps it is better to stay silent. Then, suddenly, everything is absolutely wonderful.

Not because the organization is functioning better, but because it has taught people which information is unwelcome at senior management level.

This is one reason why psychological safety is not simply a matter of whether people feel comfortable at work. It serves a very concrete function in the flow of information.

The Most Dangerous Moment Is When Everyone Starts Thinking Alike

There is another problem. Once most of a group accepts a particular explanation of a situation, every piece of contradictory information becomes more psychologically costly.

If we all believe an acquisition will succeed, the person warning about organizational culture problems is not merely providing new information; they are disrupting the shared narrative. And the issue becomes something that is simply not up for discussion!

This is where familiar mechanisms such as conformity, confirmation bias, escalating commitment to a previous decision, and groupthink come into play. They are not the same thing, but they can all work in the same direction: increasing the psychological cost of information that deviates from what the group already believes.

As a result, intelligent individuals and highly competent departments can make surprisingly poor decisions. A lack of intelligence is often not the problem at all. The problem is the architecture through which information travels to reach its destination.

But What If Cassandra Is Wrong?

Not everyone who claims that others do not listen to them is automatically a Cassandra. Every organization has people who constantly predict catastrophe. If we keep saying for long enough that something will fail, we will occasionally be right. Looking back, we will remember our accurate predictions very well, and the dozens of incorrect ones rather less clearly. That is why the solution is not to “listen more to negative people.”

The solution is far more demanding: separate the quality of the information from the status, personality, and popularity of the person presenting it.

In other words, a good organization does not need to take its Cassandras at their word. It needs to check their claims rather than ignore them.

The Problem Is Not That Organizations Lack Data

Today, they generally have too much of it. They have employee surveys, financial indicators, and data on customers, productivity, staff turnover, sick leave, sales, projects, and dozens of other things. With AI, the volume of available analysis and predictions will only grow further. But more data will not solve Cassandra's problem, because a human being still stands between the data and the decision.

A human being with their own beliefs, positions of status, decisions they want to justify, and relationships they do not want to jeopardize…

Perhaps, then, the greatest challenge for organizational decision-making in the future will not be how to produce even better predictions, but how to create organizations capable of listening to them when they dislike the results.

After all, Cassandra's curse was not that she foresaw catastrophe, but that everyone could hear her and no one thought they should take her warnings seriously.

And today, that does not require Greek mythology, just a perfectly ordinary organization.
