This is not true!!! unless in the very specific context of a criminal court proceeding. In every other context, refusal to answer a question can be used as evidence against you. For a government job application, divorce/civil proceedings, and any other conversation happening outside of a court, it is fair game to consider non answers as incriminating. In some cases you can even force a defendant to answer questions if they enjoy some kind of immunity, and hold them in contempt otherwise.
It is fair game to consider non answers as incriminating even if those comments occurred in a criminal proceeding. It is OK for an employer to look at court documents and come to a different conclusion than the jury because they are allowed to consider more context. In other words, avoiding criminal liability does not protect you from all forms of justice or consequences for your actions. Citizens absolutely should consider as much context as they can when trying to decide whether to act against their leaders.
