What is the primary use of scientific data in a courtroom setting?

The primary use of scientific data in a courtroom setting is to establish the connection of a person to a crime. Scientific data, such as DNA analysis, fingerprint evidence, ballistics data, and digital forensics, provides objective, verifiable information that can link evidence to a suspect or corroborate testimony. This type of evidence is critical in supporting or refuting claims made by either side in a legal case.

In the courtroom, the focus is on facts and evidence that can stand up to scrutiny. Scientific data contributes to building a convincing narrative based on empirical evidence rather than speculation or opinion. This helps the judge and jury to make informed decisions based on the weight of the evidence presented.

Other choices do not serve the fundamental purpose of scientific data in a legal context. For instance, entertaining the jury, confusing witnesses, and providing personal opinions are not constructive goals in a courtroom, where the emphasis is on establishing the truth based on factual evidence.
