A questioning attitude is a safety culture trait where workers challenge assumptions, notice when something seems off and pause to ask questions before continuing.

A questioning attitude is a safety culture trait in which people avoid complacency, challenge assumptions and stop to ask questions when something does not look, sound or feel right. It is the habit of asking "what could go wrong here?" and "are we sure?" rather than assuming that because a task worked yesterday, it is safe today.
The term is widely used in high-reliability industries. The U.S. Nuclear Regulatory Commission lists a questioning attitude as one of the traits of a positive safety culture, and it is a core idea in Human and Organizational Performance (HOP). It works hand in hand with stop work authority and psychological safety: workers need both the habit of questioning and the confidence that speaking up will be welcomed.
An electrician is about to start work on a panel that has been locked out. The voltage tester reads zero, but she notices a breaker label that does not match the drawing. Instead of carrying on, she stops and asks the supervisor to confirm the isolation. They discover a second supply feeding the panel that was not on the lockout procedure.
No. It is about curiosity and checking assumptions to prevent harm, not about blocking work. Good questions usually make a job go more smoothly by catching problems early.
Leaders ask questions themselves, admit when they are unsure, respond calmly to concerns and follow up on what was raised. How they react the first few times someone speaks up sets the tone.
It is most closely associated with nuclear power and other high-reliability industries, where regulators and industry groups identified it as a key trait of a strong safety culture.
Signs include regular near-miss reporting, workers using stop work authority, active discussion in pre-task briefs and few incidents where people later say they "had a bad feeling" but said nothing.
