Final answer:
The true statement about givers is that they tend to be more successful than matchers or takers in the long-term, despite possibly appearing less successful in the short-term due to their focus on helping others.
Step-by-step explanation:
When analyzing which of the following statements is true about givers, it is important to consider the context provided by organizational psychologist Adam Grant. according to research, givers - those who contribute to others without expecting anything in return - can indeed end up both more or less successful than matchers (those who aim to give and take equally) or takers (those who aim to get more than they give).
Thus, the correct statement is: givers tend to be more successful than matchers or takers. However, this success often manifests in the long-term, as their inclination to give can initially make them appear less competitive. In the short term, they may seem less successful because they spend time and effort helping others. Nevertheless, this reputation for giving can lead to better relationships, trust, and eventual success over time.
