Hidden hazards are potential dangers that are not easily seen or noticed. They can be physical, such as traps and pitfalls, or they can be psychological or emotional. Traps are hidden dangers that can cause physical harm, such as a bear trap or a snare. Pitfalls are hidden dangers that can cause mental or emotional harm, such as a false promise or a hidden agenda. Both traps and pitfalls can lead to unexpected and potentially dangerous outcomes.
