Which of the following is NOT an effective de-escalation technique?

Yelling at the person to calm down is not an effective de-escalation technique because it typically exacerbates the situation rather than diffuses it. When emotions are running high, raising one's voice can increase tension and provoke a defensive reaction from the other individual, leading to further agitation.

In contrast, speaking calmly and clearly, employing active listening skills, and showing empathy and understanding are recognized strategies for de-escalation. These methods promote a sense of safety and respect, allowing individuals to feel heard and understood, which can significantly reduce conflict and encourage a more constructive dialogue.
