What happens if an engineer presents a professional opinion without adequate knowledge of the matter?

When an engineer presents a professional opinion without adequate knowledge of the subject matter, it can lead to professional liability. This stems from the ethical obligation that engineers have to provide opinions and services based on reliable knowledge and evidence. An opinion lacking sufficient understanding can result in inadequate advice or potentially harmful decisions, which could adversely affect public safety, welfare, or the integrity of the engineering profession.

In many jurisdictions, engineers are bound by codes of ethics that require them to only provide services or opinions in areas where they are competent. Failing to do so can expose them to legal action if the performance of their duties results in damages or injuries due to their negligence. Thus, providing an unqualified opinion can lead to significant repercussions, including loss of credibility, disciplinary action, and legal liability for any fallout caused by the inaccurate advice or information shared.
