The term "negative" or "adverse" refers to something that is harmful, unfavorable, or detrimental. It can describe effects, outcomes, or conditions that lead to undesirable results. For example, in medicine, an adverse reaction to a medication can cause health complications, making it important for healthcare providers to monitor patients closely. In various contexts, such as psychology or economics, negative factors can influence behavior or market trends. For instance, negative feedback in a work environment can demotivate employees, while adverse economic conditions can lead to job losses and reduced consumer spending. Understanding these implications is crucial for effective decision-making.
