An engineer who participates in illegal gambling is likely to violate what ethical principle?

The engagement in illegal gambling by an engineer is most closely related to the principle of honesty and integrity. This principle governs an engineer's obligation to be truthful and maintain ethical behavior in all professional matters. Participating in illegal activities can compromise an engineer's credibility and trustworthiness, which are essential traits for maintaining professional integrity.

Furthermore, honesty and integrity are foundational to the engineering profession; they uphold the trust placed in engineers by the public and by their peers. When an engineer is involved in illegal gambling, it can create conflicts of interest, lead to decision-making that is not in the best interest of clients or the public, and ultimately undermine the integrity of the profession. Therefore, by participating in illegal activities, the engineer fails to act in accordance with the ethical standards expected in their field.
